Climate science and reporting are vital to understanding how our climate is changing and what we can do about it. But false information about climate change spread online is causing big problems. It’s no longer just about saying that climate change isn't happening; it’s increasingly about spreading uncertainty about its causes, its speed and the solutions. That’s making climate misinformation and disinformation harder to spot - and more divisive.

Host Jordan Dunbar is joined by Jacqui Wakefield, global disinformation reporter with the BBC World Service and guests Marco Silva, climate disinformation journalist at BBC Verify and Prof Michael E Mann, climatologist and director of the Center for Science, Sustainability and the Media at the University of Pennsylvania.

Everyone who steps outside can appreciate the value that the natural world brings to our lives. To some people, the idea of placing a monetary value on trees and mangrove forests is wrong because nature and its gifts are priceless. But others say the love of nature has not stopped it from being polluted or destroyed.

The natural world plays a major role in capturing the carbon from our atmosphere. A marketplace now exists where countries and big businesses can pay others to protect their forests, swamps and bogs in return for offsetting their emissions. But several of these schemes have faced scandal and corruption. Could the world’s largest biodiversity conference in Colombia, COP16, help put a stop to that?

Geothermal energy is renewable, reliable and powerful. So, why is most of it untapped?

That’s what our listener, Anna in the UK, wants to know. Full disclosure, she’s a geologist and is thoroughly perplexed by the lack of uptake. Geothermal is renewable, reliable and abundant and yet, less than 1% of the world’s energy is generated from it.

Host Graihagh Jackson hears about a team in Iceland who hope to "super-charge" geothermal power by drilling directly into volcanic magma. And she travels to Germany to visit Vulcan Energy, a company which is combining geothermal with extracting one of the world's most sought-after metals: Lithium. Plus, our reporter in Indonesia tells Graihagh about local opposition to some geothermal power plants.

Engineers across the globe, from China to East Africa and the US, are turning to a new, nature-based solutions to fight floods, which are becoming more likely in many places because of climate change. They’re taking a pickaxe to asphalt and concrete and instead are restoring wetlands, parks and riverbanks, turning our metropolises into so-called ‘sponge cities’. Plants, trees and lakes act just like a sponge, mopping up rainwater instead of letting it pool and eventually flood our homes.

Professor Priti Parikh tells Jordan Dunbar how these spongey solutions have many benefits beyond flooding, encouraging biodiversity, helping our mental health and storing the planet warming gas, carbon dioxide. The BBC’s China Correspondent, Laura Bicker, meets the man who came up with the concept, Professor Kongjian Yu, and visits Zhengzhou, a sponge city in the making. And Katya Reyna tells Jordan how her NGO is helping low-income communities in Portland in the US to ‘depave’ disused car parks, turning them into plant-oases.

Climate change has been tightening its grip on the people of Afghanistan, with flood after flood and drought after drought. It’s considered one of the most vulnerable countries in the world, not just because it’s warming twice as fast as the global average, but because its people’s ability to fight back has been severely hampered by decades of conflict and war. To add insult to injury, Afghanistan has contributed very little to the industrial emissions that fuel the global climate crisis.

Since the Taliban takeover in 2021, financial aid to help locals adapt has drastically dropped, leaving Afghans to take matters into their own hands. But presenters Graihagh Jackson and Barry Sadid hear how the diaspora is helping villages back home to build life-saving dams and protect themselves against extreme weather. And we ask if there’s a way for foreign governments to financially support Afghanistan without legitimizing the Taliban.

The acclaimed US sci-fi author Kim Stanley Robinson is also a star in the world of climate activism because his work often features climate change - on Earth and beyond. Robinson has been a guest speaker at the COP climate summit, and novels such as The Ministry For The Future and The Mars Trilogy are admired by everyone from Barack Obama to former UN climate chief Christiana Figueres. Robinson's books are not just imaginative but scientifically accurate, and some of their ideas have even inspired new thinking about climate-proofing technology. Kim Stanley Robinson has been talking to the Climate Question team.

With more and more people moving to cities, informal settlements are expected to grow. When floods hit these unplanned places, it can be disastrous, as we often don’t know much about them. Crucial questions often remain difficult to answer, like how many people live there, what are the buildings made of, and could they withstand a flood? In the township of Alexandra in Johannesburg, the BBC’s Nomsa Maseko visits a project using drones and artificial intelligence to shed some light on the situation, helping authorities prevent the worst impacts of flooding. And in Porto Alegre in the south of Brazil, we hear how an innovative digital map helped the emergency response – and will soon be available to all for free across the world.

This little-known pollutant is making us sick and driving the climate crisis. It commonly comes from burning coal, diesel or wood and has a habit of getting stuck in people’s lungs as well as causing glaciers to melt. In Nepal, home to some of the world’s most beautiful glaciers, we meet journalist Tulsi Rauniyar, who tells us all about the impact black carbon is having on women and children. She meets Tenzing Chogyal Sherpa, a glacier expert who maps the ice losses in the Himalayas. Zerin Osho from the Institute for Governance & Sustainable Development helps us understand why black carbon is so important - but often forgotten - in the fight against climate change, and how we can change that.

The Paris Olympics are less than a month away. The last games in Tokyo were one of the hottest on record, with more than a hundred athletes suffering heat-related illnesses. And France, the host of this year’s Olympics, is no stranger to heatwaves – the country has seen 23 since 2010.

So how are top athletes training their bodies to not only perform at their best in high temperatures, but also to protect their health? Presenter Qasa Alom heads inside a sweltering, state of the art heat chamber at Leeds Beckett University to find out how one of the fastest marathon runners in Britain, Phil Sesemann, is maximising his chances of success in his Olympic debut.

Other athletes are more used to these conditions. We join India’s top triathlete, Pragnya Mohan, for a training run and hear what it’s like to compete when the thermometer climbs above 45 degrees Celsius.

More and more athletes are adopting heat training strategies in a warming world - but do they affect men and women the same? Dr Jessica Mee, Research Fellow at the University of Worcester tells us about her pioneering research into the impacts of heat on women’s bodies.

As a new play depicts the landmark global climate change agreement, the Kyoto protocol, Jordan Dunbar has a front row seat. He heads to the historic English town of Stratford-Upon-Avon to watch the opening night of the play, Kyoto, at the Royal Shakespeare Theatre. He hears why the writers, Joe Murphy and Joe Robertson decided to dramatize the seemingly slow and tedious action of a global climate change conference. And the duo explain their goal to highlight Kyoto as a ‘parable of agreement’ in a world full of disagreement.

The programme also hears from two veterans of many real world climate change negotiations, including the Kyoto Protocol, the first global agreement to set legally binding targets. Christiana Figueres was responsible for leading climate negotiations as the Executive Secretary of the United Nations Framework Convention on Climate Change and Farhana Yamin provided legal and strategy advice to the leaders of AOSIS, the Alliance of Small Island States at Kyoto and nearly every UN climate summit since. Christiana is now the host of the 'Outrage And Optimism' podcast.

Someone dies every other day protecting the environment, according to data gathered by the campaign group, Global Witness. Even higher numbers of people are attacked or threatened.

To understand why this is happening, the BBC’s East and Central Europe Correspondent, Nick Thorpe travels to the foothills of the Carpathians in Romania, to show us how important the forests there are in fighting climate change, why they’re subject to high levels of illegal logging and consequently, clashes with environmentalists. One activist, Gabriel Păun of Agent Green, describes the numerous and brutal attacks he’s experiences whilst out documenting illegal logging. We also hear from a mother, whose son was murdered when he confronted a ‘wood thief’ in 2019. Laura Furones from Global Witness tells host Graihagh Jackson why this is happening around the world and what we can do about it.

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm? Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test. Graihagh Jackson presents an update of a programme first broadcast in 2023.

China is scouring the globe for the raw materials of the future. How will we be affected? Graihagh Jackson investigates.

Today, more than half the world’s population live in cities – and as our numbers swell, so will our cities, especially those around the Pacific Rim, where it’s predicted our largest megacities of 10 million plus will be situated. And herein lies an opportunity: 60% of the buildings needed for 2050 are not yet built.

Could we shape our cities into places that are good for the climate and also good for our mental health? Can we design buildings and infrastructure that make green decisions easier and also help us deal with stress or depression?

Jordan Dunbar hears about examples in the Netherlands and Egypt. Are there win-win options out there that can help the world deal with two of its biggest challenges?

Experts say we need to be 40 per cent more energy efficient to meet our climate goals. Is that doable? And might it save us money too?

It's a solution that's been called the main route to net zero: energy efficiency - or using less energy to get the same or better results. But there’s an issue – it's got an image problem as many people think it’s boring. And it is hard to get excited about the idea of better lightbulbs!

But energy efficiency could save us money on our bills too - especially in a warming world, where many countries will need air conditioning just to function. So does this crucial area in the fight against climate change need a rebrand. And could it even become sexy?

NOTE: The speech made by President Jimmy Carter mentioned in the programme, was made in 1977 not 1974, as stated.

In this episode, Graihagh Jackson explores the new field of climate attribution science with leading climatologist Dr Friederike Otto. Dr Otto's team of experts can now rapidly assess to what extent extreme weather events such as heatwaves, droughts or floods have - or have not - been caused by man-made climate change.

Graihagh finds out how this information is becoming crucial for disaster planning and response. She is also joined by BBC World Service disinformation reporter Jacqui Wakefield to discuss how Dr Otto's data can help fight a growing tendency by politicians and journalists to overstate the role of climate change.

In this extra episode, Graihagh Jackson hears from our friends on BBC podcast The Global Story about a case that could change the history of climate activism.

For nearly a decade, a group of elderly women argued that Switzerland’s weak climate policies violated their human rights. Their victory – the first of its kind in the European Court of Human Rights – sets a precedent 46 countries must now follow. The BBC's climate reporter, Georgina Rannard, has been covering the case for years. She shares the women’s personal stories with presenter James Reynolds, while climate lawyer Sophie Marjanac explains what it could mean for those seeking climate justice everywhere.

Corals protect humans and sustain 25% of all marine life. But reefs are under threat from climate change, and mass bleaching events mean that some scientists estimate they could disappear by 2100.

In this episode, Graihagh Jackson is joined by BBC CrowdScience presenter, Caroline Steel. We go to Puerto Rico to see how self-duplicating, carnivorous coral could be the solution. We also speak to the scientist who helped discover what was causing coral bleaching in the first place - back when climate change was commonly denied.

Ammonia has revolutionised the way we produce our food, helping us to grow much, much more... But it’s also helping to grow global greenhouse gas emissions too.

Synthetic fertilisers are actually responsible for around 5% of the planet-warming gases going into the air - that’s more than deforestation.

In this episode, Graihagh Jackson examines this challenge that modern agriculture poses to the climate, and finds out whether it’s possible to cut emissions from fertiliser use without cutting food production at the same time. She’ll also be joined by local reporters in Kenya to hear about innovative projects aiming to tackle this problem and turn farming green.

Delhi’s roads are being taken over by electric mopeds, scooters and rickshaws. More than fifty per cent of two- and three-wheelers are already electric, and the market is expected to continue growing. It’s good news for the fight against climate change. Why has the transition to green vehicles been so swift in India and what can the rest of the world learn from it?

Graihagh Jackson speaks to reporter Sushmita Pathak, who’s been chatting to those who’ve made the switch to electric as well as those who haven’t. Akshima Ghate from the RMI Foundation and Louise Ribet of C40 cities explain why these small vehicles are so popular and what countries like India and others gain from encouraging electric uptake. From better air quality and healthier children to energy security and manufacturing expertise, there are many benefits beyond mitigating climate change.

Every year, the great migration sees hundreds of thousands of wildebeest, gazelles, zebras and antelopes migrate from the Serengeti plains in Tanzania to the Maasai Mara in Kenya, in search of water and juicy grass. But rising temperatures and unpredictable weather are changing this epic animal journey dramatically. It’s the same for great white sharks, which are being spotted in areas where they’d never normally live.

Tanzanian safari guide Neema Amos takes us into the Serengeti to explain why the wildebeest migration is so important. And shark expert Trisha Atwood reveals how these changes affect not just the animals, but our fight against climate change itself.

It may sound like the stuff of science fiction, but the idea of assembling giant solar farms in space and then beaming the renewable energy back down to Earth is gaining real life traction. Some advocates have claimed it could supply all the world’s energy needs by 2050.

But how would these solar farms be assembled, how much fuel and money would it take to blast them into space in the first place, and how would we safely beam their energy back to Earth?

In 2023, Sophie Eastaugh and Luke Jones spoke to Sanjay Vijendran, in charge of space-based solar at the European Space Agency, learn about the history of the idea from Rick Tumlinson, founder of SpaceFund, and hear words of caution from Dr Jovana Radulovic, head of mechanical and design engineering at Portsmouth University in the UK. Plus, French astronaut Thomas Pesquet describes life on the International Space Station and how it’s powered.

Graihagh chats to the BBC World Service's Global Story podcast about a plan for a super-category for storms. Is climate change making them so powerful that we need a new grade?

At the big COP climate summit last December, more than 20 countries pledged to triple global nuclear capacity by 2050 to help cut carbon emissions. The signatories included familiar nuclear names such as the US, France and Japan...but also newcomers, like Ghana.

Although Ghana doesn’t currently have any nuclear power plants, president Nana Akufo-Addo says he wants to build one or two by 2030. So why is this African nation turning to nuclear? How will it pay for the multi-billion-dollar power plants? And will this help fight climate change?

Presenter Graihagh Jackson is joined by: on-the-ground reporter Thomas Naadi; Dr Michael Bluck, Director of the Centre for Nuclear Engineering at Imperial College London; and Dr Kacper Szulecki, research professor at the Norwegian Institute for International Affairs.

Global temperatures have already increased by around 1.3C above pre-industrial levels, but this warming is not spread evenly across the planet. The Arctic, despite being one of the coldest regions on Earth, has become a hotspot for global warming.

Local temperatures there are rising as much as four-times faster than in other parts of the world. This rapid warming is unsettling the delicate environmental balance, causing significant ice loss – with implications for both the region and the wider world.

In a previous episode on the Arctic region, Graihagh Jackson explored the impact that climate change was having on the people – and ice sheet – of Greenland. In the second part of The Climate Question's focus on the High North, she explores the implications of an increasingly ice-free region on global politics, military relations, and trade.

2024 will see billions of voters head to the polls in a record-breaking year for elections. It follows 2023 – another record-breaking year for the climate... so could global warming impact the way people vote? Or will it be eclipsed by the other big issues that dominate news headlines, like inflation and the cost of living, healthcare, education, and jobs.

In this episode, presenter Graihagh Jackson hears from voters all over the world, and dives into research examining their priorities and what motivates them when they’re at the ballot box. She also finds out how climate change policies affected the outcome of recent elections in the Netherlands and Australia.

Lake Sihwa in South Korea is home to the world’s largest operating tidal power station, using the tides to generate enough power for a city of half a million people. This regular rise and fall of the seas is more predictable than sunny or windy weather and can be forecast years in advance. Nine thousand miles away in Northern Ireland is Strangford Lough. A narrow inlet leading to the mighty Atlantic Ocean means it’s one of the world’s best sites for harnessing tidal energy. The fast and strong currents have led to the world’s first commercial-scale tidal energy power station being built here. But now that’s being decommissioned.

The technology for harnessing tidal energy has been around for more than half a century and the potential to create energy from the sea is huge. Yet tidal power only accounts for a tiny proportion of the global renewable energy mix. Presenter Graihagh Jackson finds out what’s holding tidal power back.

The future of flying might depend on used cooking oil, plants and green electricity. Sustainable aviation fuels, known as SAF, are made from less carbon-intensive processes and renewable sources. Airlines are touting them as the key to decarbonising flying.

The aviation industry has pledged to move from 2.5% of all global CO2 emissions to net zero by 2050 – with these alternative fuels being the cornerstone of the strategy. However, there’s little SAF actually being produced, it, and it’s much more expensive than fossil fuels. Can the technologies really take off?

Climate Question host Graihagh Jackson investigates, with reporting from the BBC's Monica Miller in Malaysia and Singapore.

The deal at this year's COP conference in Dubai is being hailed as "historic" because it's the first time nearly 200 countries have all acknowledged the role of fossil fuels in Climate Change. But critics says the agreement is riddled with loopholes, and that the pledge to "transition" from oil, gas, and coal is too weak.

So who's right? And what difference will this year's discussions make? Graihagh Jackson gets the low-down from COP from BBC Climate Editor Justin Rowlatt, and she talks to three leading experts on Climate Change diplomacy.

As the world’s attention turns to this year’s COP summit in the UAE, questions remain about the host country and conference president.

It’s not the first time that an oil-producing country has hosted the climate change summit. But some environmental campaigners are unhappy about COP28 being held in the United Arab Emirates, and the choice of conference president, Dr. Sultan Al-Jaber – the CEO of the national oil company, ADNOC.

However, supporters say that the country is extremely vulnerable to the effects of climate change, so it has as much of a right to host the conference as anyone else. Meanwhile, Dr Al-Jaber boasts considerable experience working in renewables – having previously run the UAE’s renewable energy company MASDAR.

So what’s really going on? To find out more, presenter Graihagh Jackson is joined by:

It's the world's biggest - and most controversial - climate conference. But how does it actually work? And does it make a difference? Jordan Dunbar investigates.

To help get some simple answers to simple questions, Jordan is joined by climate experts- Dr Mosunda Mumba, Secretary General of the Wetlands Convention Professor David Victor of Innovation and Public Policy University of California, San Diego, USA Adil Najim, Professor of International Relations and Environment at Boston University's Pardee school in the United States.

Check out the other explainers in these series including – ‘What Is Climate Change?’ and ‘Why Is 1.5 Degrees Important?’

In his latest Climate Change 101, Jordan Dunbar finds out why 1.5C is the world's target for limiting global warming. Why 1.5 degrees? And what happens if we miss the goal?

Nearly three decades since the United Nations climate talks began, we take a look at what it has achieved when it comes to tackling climate change. We also look towards COP 28 taking place in Dubai and ask what progress can be made at the latest round of negotiations. It’s the only international negotiation on climate change and a unique opportunity to get agreement on how to best tackle global warming – but it has its critics as well as its fans.

As the world faces up to the increasingly apparent effects of climate change, access to accurate information that helps us to understand what’s going on, why, and what we can do about it, is vital. But in its efforts to do this, the science community is facing a growing amount of abuse from people who do not believe what they’re saying. Anger at the science is leading to threats against the scientists in some cases. In this episode, presenter Jordan Dunbar is joined by BBC Verify’s Merlyn Thomas to find out more and are joined by the following guests: Nihan Kalle, BBC Monitoring, based in Istanbul Helene Muri, research professor in climate change at the Norwegian University of Science and Technology.

Greenland is an island covered in a sheet of ice that is over 3km thick in places, containing 7.4 metres of average global sea level rise. Due to climate change, it’s melting at an astonishing rate. We meet some of the people being forced to rapidly adapt their traditional ways of life. And find out why ice loss means sea level rises for elsewhere in the world – but the opposite for the island itself

The Yasuni National Park in Ecuador forms part of the Amazon rainforest and is one of the most bio-diverse places on the planet. It also produces 60,000 barrels of oil per day. In a recent referendum, held as part of Ecuador’s Presidential elections, people voted to stop drilling for oil – including the newly elected President Daniel Noboa. We visit the town of El Coca – the gateway to the park - where the result thrilled people who are concerned about the climate. But many, especially those whose livelihoods depend on the oil industry, feel the opposite. Presenter Sophie Eastaugh speaks to: Lisette Arevalo, reporter in Ecuador Alejandra Santillana, activist with Yasunidos group in Ecuador who campaigned for the vote Fernando Santos, Ecuador’s Energy & Mining Minister Tessa Khan, climate lawyer and cofounder of the Climate Litigation Network, UK Navraj Singh Ghaleigh, Senior Lecturer in climate law at Edinburgh University, UK

This week we hear from listeners about the ways they cope and how they remain positive on climate change. From being involved in a like-minded community, to taking action in everyday ways. Or just knowing that the brightest minds are pushing innovative climate solutions forward every day.

In a wave of negative climate news, it can be easy to feel overwhelmed and uncertain about the future. Climate change is a real threat, and it’s normal to experience worry, but there are reasons to be positive. We hear from a psychologist about how ‘climate anxiety’ is a normal response to the uncertainty around us and from a Libyan climate activist about what motivates her, despite experiencing climate devastation in her own country.

Bill Gates, the tech billionaire turned philanthropist, has been combating poverty, disease, and inequity around the world for decades. However, in recent years he has shifted focus and resources towards the climate crisis.

Gates believes fighting climate change and fighting poverty are two sides of the same coin. Food, health and economic crises will last longer and become more severe as climate threats escalate; disproportionately impacting the most vulnerable communities.

Surprisingly, Gates remains optimistic and believes the power of human ingenuity will win out with a technology-driven approach in both mitigation and adaptation.

Graihagh Jackson sits down with Mr Gates to talk about his positive outlook and the billions he’s investing in tackling climate change.

In this, the second episode in our spin-off series on Climate Quitters, we invite trailblazers from three different continents to reveal the ups and down, highs and lows of their new lives in climate conscious careers.

In Mumbai, Namita Dandekar swapped a role marketing stock for one of India's largest - and wealthiest - conglomerates for a front-line position with The RainTree Foundation, an organisation that works with rural communities to introduce climate friendly practices into their everyday lives and livelihoods.

In Vihiga County in Kenya, Kevin Makova traded in his job as a schoolteacher to create sustainable employment opportunities for members of the community keen to work in climate and conservation focused jobs.

And in Berkeley, California, Eugene Kirpichov said goodbye to a lucrative post developing AI systems for Google to build a new, global workforce that he hopes will be capable of solving the climate crisis conundrum.

But is the grass always greener - and cleaner - for climate quitters? What are the realities of life on the other side of that leap? And does putting the planet first come at a personal cost?

In this globe-spanning episode, your host, Paul Connolly, probes all three guests for their views and experiences so far - and we go a step further to bring you on-the-ground, in-person reports from the projects based in both India and Kenya.

Bornholm – a Danish island in the Baltic Sea – is trying to go carbon neutral by 2025. It is a lofty ambition that would put the island decades ahead of most countries. This dream has been 15 years in the making; a crash in fish stocks meant Bornholmers had to reinvent themselves and they chose to become ‘the bright green island’. Since then, they have been making biogas from pig manure, building wind turbine after wind turbine, and now they are piloting new ways of storing this renewable energy, including in a battery made of salt.

The island is not just trying to rid itself of fossil fuels – it is also aiming to go zero waste by 2032. Graihagh Jackson teams up with CrowdScience presenter Caroline Steel to explore Bornholm’s double quest to go green.The changes have not just been at top-level – the island’s businesses and 40,000 residents have been encouraged to reduce their climate impact too. Graihagh visits a brewery whose production has gone carbon neutral by capturing CO2 to create the bubbles in its beers, and meets a chef whose Michelin-star restaurant uses locally-sourced food.

And over on CrowdScience, Caroline tackles Bornholm’s zero waste ambition, visiting a project turning used nappies into compost and a glassblower making tableware out of wasted insulin vials. See link below.

Will Bornholm make its bold goals, and what lessons can be learned for elsewhere?

The live music industry is booming. With global growth in concerts and festivals, more and more of us are enjoying our favourite bands and artists live. The music industry now relies on touring for money – encouraging more and more bands to travel and fans to see them. This is causing emissions to soar just like the private jets. So what can be done? Jordan Dunbar discovers the problem isn’t coming from who you might think and that this could be a climate opportunity rather than a problem.

Guests: Ben Pol, Afrobeats star Prof Carly McLachlan, Director of the Tyndall Centre for Climate Research, University of Manchester Jordi Herreruela, Director of the Cruilla Barcelona Festival Luke Howells, Head of Sustainability for Coldplay and Glastonbury Festival Henry Stuart, Co-Founder and CEO of Visualise

The Prime Minister of Barbados, Mia Mottley, has been raising awareness of the impact that climate change is having on small island nations like hers, from the Caribbean to the Indian and Pacific Oceans.

In addition to facing more extreme weather and temperatures, these islands also have to contend with the threat posed by rising sea levels – which, for some islands, is existential.

In this episode, Qasa Alom speaks to reporters in Fiji and the Maldives about what small island nations can do to survive.

Jordan Dunbar introduces The Climate Question's guide to the Climate Change basics - with the help of some friends of the show.

July 2023 has been confirmed as the hottest month ever on Earth. A combination of heatwaves across the Northern Hemisphere, unseasonable warmth in parts of South America and Antarctica, and global sea surface temperatures around 0.51°C above the 30-year average, meant it broke all previous records.

Climate scientists are now poring over the data, including Prof Jim Skea, the newly-elected chair of the Intergovernmental Panel on Climate Change (IPCC). He joins presenter Graihagh Jackson to discuss how worried we should be, and the challenges ahead as he takes up the most important role in global climate science.

Have you thought about quitting your job because of climate change?

Research shows more and more people are worried about their career’s impact on the planet. So this week The Climate Question hears from four people from around the world who’ve taken the plunge and done it.

Luke Jones meets an air steward who's swapped flying for teaching; a restaurant critic who's become a tree-planter; a fossil fuel company engineer who's switching to working in renewables; and a multinational CEO turned sustainable business campaigner.

Presenter: Luke Jones Series Producers: Alex Lewis and Simon Watts Sound Engineer: Tom Brignell Editor: China Collins

Funeral rites are steeped in culture, tradition and faith, with most of the world opting for cremation or burial. However, with new research now revealing the carbon impact of established funeral choices, more people are questioning their cost to the climate.

With alternatives such as ‘water cremation’ and ‘eco-burials’ becoming available, will people start to consider another way?

Presenter Jordan Dunbar hears about initiatives in India to modify traditional funeral pyres, calculates the climate cost of the most common choices, and hears from Archbishop Desmond Tutu’s daughter, Rev. Mpho Tutu van Furth, about her surprise at her father’s final act on earth.

Climate change has been tightening its grip on the people of Afghanistan, with flood after flood and drought after drought. It’s considered to be one of the most vulnerable countries in the world, not just because it's warming twice as fast as the global average, but because its people’s ability to fight back has been severely hampered by decades of conflict and war. To add insult to injury, Afghanistan has contributed very little to the climate crisis. Since the Taliban takeover two years ago, financial aid to help locals adapt has drastically dropped, leaving Afghans to take matters into their own hands. Presenters Graihagh Jackson and Barry Sadid hear how the diaspora are helping villages back home to build life-saving dams and protect themselves against flood and drought. And we ask if there’s a way for foreign governments to financially support Afghanistan without legitimising the Taliban.

Scientists say an El Nino weather event has started. Its effects will be felt everywhere in the form of heavier rainfall in some parts of the world and deeper droughts in others. What's the link with Climate Change? And is it making it harder for us to prepare?

On this week's edition of The Climate Question, Graihagh gets a briefing on El Nino from a leading expert; we travel to Peru to meet the coastal communities on the front line; and we hear how ancient civilisations not only learned to deal with El Nino, but managed to use it to their advantage.

The journey from catwalk, to wardrobe, to landfill is getting shorter and shorter. Our demands for fast fashion mean around 100 billion garments are produced every year. We’re buying more, then wearing them less often. Many will end up in the trash. Not only that, there’s been a big growth in clothes being made out of synthetic materials originating from crude oil. In this updated edition, we ask: can fashion cost less to the climate? and how much progress is the industry making? Speaking to Kate Lamble and Sophie Eastaugh are- • Vanessa Friedman, New York Times Fashion Editor • Lily Cole Fashion model, actress and podcast host ‘Who Cares Wins’ • Phillip Meister, Quantis Sustainability Consulting • Claire Bergkamp, Textile Exchange • Sonya Bhonsle, Global Head of Value Chains, CDP.

Mia Mottley, Prime Minister of Barbados, is on a mission to fight climate change through a radical scheme to reform the international financial system.

Called the Bridgetown Initiative, her plan aims to transform global institutions such as the IMF and the World Bank – freeing up billions, maybe even trillions of dollars, for poorer countries that are struggling to cope with the impacts of a hotter planet.

Presenter Graihagh Jackson is joined by the BBC’s Climate Editor, Justin Rowlatt, who interviewed Prime Minister Mottley at a crucial climate finance summit in Paris. With time running out in the battle to keep the world below the 1.5C warming threshold, we find out more about her plan, how it works and the progress being made.

With the Ukrainian counter-offensive underway, Sophie Eastaugh looks at the climate damage caused by the conflict there and by the recent civil war in Tigray, Ethiopia. Sophie speaks to Lennard de Klerk, a Dutch specialist in carbon accounting, who’s just published the most comprehensive analysis yet of the greenhouse gas emissions caused by the fighting in Ukraine. For her part, an environmental researcher in Kyiv tells The Climate Question her country may have an opportunity to build back greener once the war is over.

The programme also hears from farmers in Tigray about how a region once praised internationally for its reforestation efforts is now losing tree cover at an alarming rate.

And this edition of The Climate Question looks more broadly at the carbon footprint of militaries around the world, speaking to Professor Neta Crawford, one of the leading experts in the field.

This week, we’re off to Costa Rica, an eco-tourism hotspot in collaboration with BBC’s The Travel Show.The Climate Question gets lots of emails from listeners asking what they can do about climate change. Is it morally justifiable to fly for leisure? Which type of fish is most sustainable? And how can I use my career or free time to help the planet? In this programme a panel of experts answer your questions and run through some of the most effective things you can do to make a difference, wherever you are in the world.

How can you have a successful relationship with someone if you believe passionately in climate action, but they don’t? The fate of our planet can be a divisive, emotive, even frightening issue. It’s something that’s tearing more and more couples and families apart, experts have told us.

It’s not easy getting past those differences with the ones we love, but it is possible. We speak to a couple, as well as a mother and daughter, to find out how. And we ask whether the way we talk to our loved ones about climate change might offer important lessons on how we discuss the issue more broadly.

The impacts of climate change are already being felt around the world. Research shows that some groups are disproportionately affected. Women already face many socioeconomic, cultural, and political inequities, with those living in areas heavily impacted by natural disasters related to climate change, such as floods, drought, and coastal erosion, enduring even worse outcomes. So what can be done to address this?

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm? Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test. Plus, ten years on from the unveiling of the world’s first lab-grown meat, we ask why it’s still only available to buy at one restaurant in Singapore, and only on Thursdays.

If you are planning a trip, but you want to check the climate impact before choosing how to get there, then beware. Google has been seriously underestimating the carbon footprint of plane flights, and overestimating that of some train journeys. And its calculations don’t just appear in its search results, but also feed the sites of more and more online booking companies, like Skyscanner and Booking.com. To be fair, carbon footprints are actually very hard to get right, as the BBC’s Climate Editor, Justin Rowlatt, discovers on his own trip to Rotterdam. On the way out, he takes the Eurostar high-speed train, whose carbon emissions depend on the weather over the North Sea that day. On the way back he catches a plane, whose climate impact… also depends on the day’s weather conditions over the North Sea. So what is Google doing to fix its methodology and can we trust carbon footprint calculations at all? And do passengers even really care that much about the environmental impact of their journey, or should they be made to pay for it directly?

The idea of cities where everything you need on a daily basis can be reached within a quarter of an hour by foot or bike has grown in popularity in recent years, as local authorities adopt more sustainable approaches to urban planning. In theory, by having work, shopping, education, healthcare, and leisure all within a short distance could reduce dependency on cars, improving personal health and lowering carbon emissions. But the idea of adapting cities in this way hasn’t been universally-welcomed.

Many blame our obsession with economic growth as being one of the biggest drivers of climate change. The United Nations is currently looking at options for what might replace Gross Domestic Product (GDP) as the world’s primary go-to indicator of success, taking into account factors including sustainability and the natural environment. If this happens, it would be the biggest shift in how economies are measured since nations first started using GDP in 1953, 70 years ago.

Wind and solar power will play a crucial role in curbing climate change, but what happens to all the worn-out turbines and photovoltaic panels once they are past their best?

Most wind turbine blades are almost impossible to recycle, and solar panels are very expensive to disassemble, but efforts are under way to prevent a possible renewable waste mountain.

Presenter Graihagh Jackson hears how old wind turbine blades are being turned into everything from bridges to flowerbeds, and we visit one of the world’s only solar panel recycling facilities. Plus – what’s the carbon footprint of a wind turbine or a solar panel in the first place?

Plus we hear from listeners Prateek, Alex and Elle.

It may sound like the stuff of science fiction, but the idea of assembling giant solar farms in space and then beaming the renewable energy back down to Earth is gaining real life traction. Some advocates have claimed it could supply all the world’s energy needs by 2050.

But how would these solar farms be assembled, how much fuel and money would it take to blast them into space in the first place, and how would we safely beam their energy back to Earth?

Sophie Eastaugh and Luke Jones speak to Sanjay Vijendran, in charge of space-based solar at the European Space Agency, learn about the history of the idea from Rick Tumlinson, founder of SpaceFund, and hear words of caution from Dr Jovana Radulovic, head of mechanical and design engineering at Portsmouth University in the UK. Plus, French astronaut Thomas Pesquet describes life on the International Space Station and how it’s powered.

In 1856, an American woman called Eunice Newton Foote discovered that higher levels of carbon dioxide would warm the planet. But credit for discovering climate change was given to someone else who made the same discovery three years later. We celebrate Foote’s role in early climate science by recreating her little-known experiment and asking if there are some voices that continue to be overlooked in climate science today – and how we overcome these climate blind spots?

With rolling blackouts and huge waste disposal issues a regular occurrence in large parts of Sub-Saharan Africa, we look at how green tech start-ups offer smart, climate-friendly ways to solve the issues holding the region back.

In Malawi, our repórter Peter Jengwa meets Admore Chiumia, whose company Green Impact Technologies turns waste into energy.

In Zimbabwe, the BBC’s Shingai Nyoka visits AI entrepreneur Leroy Nyangani who’s come up with a way of making solar energy more financially accessible, while also solving a big problem of energy access in the country where, almost 70% are not connected to the grid and blackouts are the norm.

Audrey-Cynthia Yamadjako from the African Development Bank outlines a new scheme designed to support green SMEs on the continent.

Presenter Luke Jones is joined by the BBC’s Karnie Sharp who was raised in South Africa. They discuss how, with proper support, green solutions to everyday problems may unlock Africa’s economic and human potential.

Worsening energy blackouts are crippling South Africa. They’re being caused in part by an over-reliance on ageing coal-fired power stations which can’t produce enough electricity. The government has an ambitious plan to rapidly build up solar and wind power by opening up the grid to private providers. But it’s facing opposition from the coal lobby.

Will this electricity crisis be the thing that finally pushes South Africa to implement its climate plan? And can it be implemented in a way that treats all South Africans equally, and doesn’t unfairly benefit a rich minority?

Some oil and gas giants are being pushed by shareholders to adopt more climate friendly strategies.

An environmental law charity is suing the directors of a global oil company, arguing their climate strategy is not adequate to meet current targets, supported by other shareholders. Elsewhere, a group of investors in another fossil fuel giant, recently unseated multiple board members in an effort to force a change of direction.

Our warming world is changing the geographical distribution of several animal species. Mosquitoes have been able to colonise new regions, places where they haven’t been found before including Afghanistan and countries in Europe.

According to the World Health Organisation, dengue fever is the most critical mosquito-borne viral disease in the world. Globally there’s been a 30-fold increase in infections in the last 50 years.

But is there a way to prevent the spread of the disease?

Record-breaking temperatures in the Alps in Europe have led to a disappointing ski season so far. Some slopes have been more brown than white, while others have been forced to close all together. Many worry this is a bad omen for the whole industry – which employs thousands globally.

This is part of a wider trend of unpredictable weather. Some ski resorts are trying to adapt, by making artificial snow for example, but these short-term measures aren’t always sustainable.

It’s predicted that the Alps will have 25% less snow by 2050, whereas resorts in Arctic Sweden are forecast to stay colder for longer. Could the northern country become skiing’s last resort, or will the industry have to fundamentally change to survive?

India has made a lot of climate pledges in the last couple of years. They’ve had mixed reviews. Some have applauded the country’s ambition – including committing to a net zero target - while others argue it’s still too reliant on coal, the dirtiest of fossil fuels. India is already facing the brutal impacts of a warming planet and, with a population of around 1.4 billion, its energy demand is huge – and growing. But there are reasons to be optimistic. We travel to a rural area near Mumbai to hear about the benefits of solar energy and get a temperature check from BBC Marathi’s Janhavee Moole on what people are discussing locally.

We also speak to two experts to better understand how we can rate India’s commitments compared with other countries as well as the barriers it could face as it transitions to a greener economy.

In 2009, the G20 countries pledged to phase out 'inefficient' fossil fuel subsidies, which have long been seen as an obstacle to fighting climate change. But today, subsidies for oil and gas producers are at record levels -- $64 billion in 2021. It’s not just to do with the war in Ukraine.

Despite its image as a leader on climate change, the UK is listed as one of the worst offenders for government support to oil and gas producers because of its generous tax relief. We hear from the centre of the UK’s oil and gas industry in Aberdeen, Scotland, about the difficult balance between energy security, jobs and climate change.

The Arctic is warming four times faster than the global average temperature. Ice caps are melting, forcing the indigenous Inuit community living around the Northwest passage to change their way of life. Polar bears and wildlife are losing their habitats and the ability to hunt.

Further south, Middle Eastern countries are facing temperatures above 50 Celsius more regularly.

We speak to people living in these rapidly warming parts of the world and find out why their countries are warming faster than others and what impact it is having.

Heatwaves are already the most deadly of climate risks. If we don’t keep climate change in check, we’ll experience more of them, reaching even higher temperatures.

Already we need cooling to keep our homes, hospitals and workplaces comfortable, our vaccines stable and our food nutritious. As the planet warms up we’ll have even greater need.

Currently the cooling industry is incredibly polluting – it accounts for around 10% of global CO2 emissions. And the demand for it is only going to increase. An International Energy Agency report said that the amount of air conditioners will grow by 5.6 billion by 2050, up from 1.6 billion today – which amounts to 10 new ACs sold every second for the next 30 years.

So how can we cool our warming world sustainably?

This episode looks at the biggest problems with cooling, the rapid rise in air conditioners and the surprisingly simple ways we can keep things cool without using any energy at all.

Half of all the energy we use globally goes on heating and cooling. We need heating for all sorts of things; from keeping our homes warm to industry which needs super high temperatures. At the moment, the heat we use is mostly powered by polluting fossil fuels, a huge driver of climate change. But can renewables deliver the high temperatures and a constant supply which are so vital? In this episode we visit the world's first commercial-scale sand battery in Finland and find out how it’s using renewables to heat 100 homes and a public swimming pool.

Extreme weather is becoming even more extreme thanks to climate change. Countless lives are claimed by heatwaves, cold snaps, cyclones, droughts and torrential rains every year around the world. Climate change threatens to make things worse. But the United Nations is spearheading new action to make sure every person on Earth is protected by early warning systems within the next five years. It’s hoped that this could dramatically reduce the numbers of deaths caused by extreme weather.

Back in 2010, FIFA announced that the tiny country of Qatar would host the 2022 World Cup. It would be the first Middle Eastern country to do so. The tournament has seen thousands of fans travel to see it, with millions tuning in around the world. But it hasn’t been without controversy.

The event’s organisers claimed that it would be the first fully carbon-neutral World Cup. A big new solar park was built, fleets of electric buses were released onto the roads and climate-friendly projects were set up to offset emissions.

Some say that organisers are trying to do the right thing. But others are critical, arguing that emissions have been underestimated and that the carbon-neutral claim is misleading.

This episode dives into the debate and asks if the 2022 World Cup was really as green as it seemed.

The ecosystems of the land and ocean absorb around half our planet warming emissions. But these are being destroyed by human activity. At the same time, climate change is a primary driver of the destruction of these habitats and biodiversity loss. If biodiversity is our strongest natural defence against climate change (as it’s been described), what’s stopping us from doing more to protect it?

What we eat has a massive impact on global warming. Meat and dairy are among the biggest drivers of the climate crisis - creating more planet-warming emissions than all the cars in the world. As we all try to reduce our carbon footprints, it’s not surprising that the global market for meat alternatives that come from soy or pea protein is growing at a huge rate. In fact it’s estimated that by the end of the decade it will be worth nearly 20 times what it was in 2018. But are these meat substitutes as good for the planet as we’d like to think?

At the start of COP 27 Egyptian President Fattah al-Sisi told the world that it was vital that African countries receive "appropriate support and funding according to the principle of shared responsibilities and burdens”.

For years the richest nations have been accused of failing to meet their $100 billion-a-year pledge for funding. It turn out this doesn’t even scratch the surface - a recent report puts the estimated figure for all of Africa’s climate needs closer to $2.8 trillion dollars.

The Climate Question looks at whether COP 27 made a difference to the money flowing and asks how African countries will get what they need to protect themselves from climate change. Presenters Graihagh Jackson and Neal Razzell are joined by:

The world has been in Egypt for COP27, the UN’s big climate talks. It’s a country that’s already feeling the acute effects of climate change – temperatures have risen by two degrees since last century, damaging farming and driving up food prices.

Tensions are rising, but many are concerned that restrictions on the right to protest and freedom of expression mean that climate change is not getting the attention it deserves and preventing Egypt from adapting.

The Climate Question hears how global warming is affecting Egypt – and whether the government is listening.

If there were fewer of us, would the amount of greenhouse gasses we emit reduce? It’s a question that often creeps up in discussions about climate change. Studies show that the global population will decline eventually and populations in many rich nations are already declining. However, 11,000 scientists signed a paper warning of “untold suffering due to the climate crisis” unless society transforms, including the reversal of population growth. But an analysis by the United Nations found that affluence has a greater impact on the climate than population. When we talk about overpopulation, what are we really saying and where does the conversation go from here?

We’ve been told that big finance is crucial to the transition to net zero, and billions of dollars are invested in so-called sustainable finance every year. But the BBC’s Climate Editor Justin Rowlatt, together with the Bureau of Investigative Journalism, have been looking into a new green finance product and found that not all is quite as it seems.

Their investigation has found an example of sustainable finance backed by the multi-national bank HSBC being used to help extract a vast new reserve of fossil fuels in Brazil. And it's not the only one. Some question how this can happen, while others defend it. Presenters Justin Rowlatt and Graihagh Jackson are joined by: Tariq Fancy, former Global Chief Investment officer for Sustainable Investing at BlackRock Caroline Harrison, Head of Market Intelligence Research at Climate Bonds Initiative Ulf Erlandsson, Chief Executive at the Anthropocene Fixed Income Institute Julia Carneiro, journalist based in Brazil Email us: [email protected]

Africa accounts for around 10 per cent of the world's known fossil-fuel reserves. But plans to build an oil pipeline through East Africa to transport hundreds of thousands of barrels a day have been condemned by the European Union.

The pipeline, which runs from the source in Uganda to the Tanzanian coast, will generate billions of dollars a year. But critics say it will release tens of millions of tonnes of carbon dioxide into the atmosphere.

In this programme we hear from the people involved in the fight over the East African Crude Oil Pipeline, and find out if they think it will go ahead.

We know many of the obstacles in the way of a creating a cleaner planet - making cement green, decarbonising electricity or creating affordable clean transport. But how do we get the experts the funding they need to bring these solutions to the world?

Many people see innovation prizes as the answer - from Prince William’s ‘Earthshot’ to Elon Musk’s ‘X-Prize’ there are hundreds of millions of dollars up for grabs. Is this the best way to find solutions to the climate crisis? Who really wins from these prizes, companies or the climate?

The race to reduce emissions has more and more nations reaching for the nuclear option. Nuclear power plants are being built around the world, generating carbon-free electricity day and night, windy or calm. But they also generate radioactive waste, some of which can remain deadly for thousands of years. Thousands of tonnes of nuclear waste currently sit in “temporary” sites, some decades old. This has been fuel to critics who have described nuclear power as a scourge for future generations. No country yet has a permanent solution to the problem.

Now, almost 70 years after the first nuclear plant, Finland is set to change that. Engineers have been creating a giant cavern they say will become the world’s first permanent nuclear waste disposal site. Can it silence the critics or are we just passing on the problem to future generations?

Floods in Pakistan have destroyed or damaged millions of homes, schools and businesses. So far nearly 1500 people have died and 33 million have been affected. With Pakistan contributing less than 1% to global CO2 emissions, a keen sense of injustice is felt in the country, and demands for international support have been made. The Pakistan government has called it a “climate catastrophe” and according to the World Weather Attribution group, it is likely climate change led to intense rainfall. But critics blame mismanagement and say Pakistan should have been more prepared for the inevitable. In this programme, we tell the story of the collapse of one building to see how much of the crisis can be blamed on climate change.

As climate change brings rising temperatures and shifting patterns of rainfall, animals are adapting to keep pace. Bird’s bodies are growing smaller, their wingspan longer, lizards are growing larger thumb pads to help them grip more tightly in hurricane strength winds, beak size is changing.

We visit the Galapagos, where evolution was first discovered by Charles Darwin, to investigate the many ways the behaviour and physiology of animals are changing to survive the impact of climate change. But can they do it quickly enough?

Images are a key part of communicating climate change, and shape how we understand the crisis unfolding around us. But while lots of research has been done into the language we use to talk about climate, images are often left out of the conversation.

As a result, over time, a limited set of images have come to dominate how we think of climate change – like polar bears and melting glaciers - which haven’t kept up with the changing conversation about the crisis. All too often, these images tend to be abstract, removed from our daily lives and typically don’t feature people - when we know that climate change is happening all around us, all the time, and is very much a story with people and communities at its core.

So how can we develop a new, and more effective visual language for climate change? What kind of images ‘work’ to both convey the urgency of the crisis as well as inspire behavioural change? And what are some of the ways in which photographers are seeking to represent the crisis in a way that transforms apathy into action?

In 1985 British scientist Jonathan Shanklin and colleagues published a study that shocked the world. The study revealed a hole in the Earth’s atmosphere right over Antarctica. It had been caused over time by chemicals known as CFCs, used in things like fridges, air conditioning units and aerosol cans. These were destroying the layer of ozone in the stratosphere which protects us from most of the sun's ultraviolet radiation - without it, cases of skin cancer would soar. Less than two years after the discovery, world leaders signed an agreement called the Montreal Protocol, committing to phase out CFCs. It has been described as the most successful international treaty of all time - every UN country has signed up, and ozone is expected to return to its previous levels around the middle of the century. So what can we learn from how we tackled the ozone hole in how we address climate change?

From the Aztecs to the Zoroastrians, humans have always prayed for rain. We’ve tried dances, ritual sacrifices and even blowing up the sky to boost rainfall. This might sound crazy but desperate times call for desperate measures.

Climate change is making people desperate again, in some regions droughts are becoming more frequent and pervasive whereas in others floods threaten livelihoods and cities. We have already affected our weather cycle but can we control it? Many governments have turned to cloud seeding programmes to try to manipulate rain to fall where they desire it to. But does it actually work, and what are the potential ramifications? We speak to experts about how people are trying to create rain, whether we’re on the brink of a geopolitical nightmare.

In rural North East Spain, proposals to build hundreds of new wind turbines have sparked opposition and divided communities. And it isn’t only Spain. There has been resistance to wind power projects across the world from Mexico to the US. Opposition groups have succeeded in delaying, and sometimes cancelling, the construction of new wind farms. To move away from fossil fuels, we will need a huge expansion in renewables. But will wind power be able to meet this challenge in the face of local opposition around the world?

The Ocean, it covers more than 70% of the surface if our planet, it provides us with food, medicine and even influences the weather.

For years its also helped to mitigate the effects of climate change. Since the 1970’s over 90% of atmospheric warming caused by green house gas emissions has been absorbed by our Oceans. But this comes at a cost.

Overtime their temperatures have risen and this has had disastrous impact on some of our most important ecosystems. Join us on a dive into the world of warming waters to discover what this means for life below the waves.

Shopping online is nothing new but with the rise of influencer culture, livestreaming, and social commerce buying stuff has never been easier.

Research suggests that the production and use of household goods and services is responsible for about 60% of global greenhouse gas emissions.

So is influencer culture making us buy more - contributing to climate change? Or is it more complicated than that? In this programme we hear from Nigerian influencer Noble Igwe and eco-influencer Rosie Okotcha. As well as finding out about the growing popularity of influencers in India and the potential of Chinese live-streamers to become environmental icons.

Since the 1990s, air flight has made the world a smaller place. In one 24-hour period you can fly to the other end of the globe. In an hour you might be able to skip the traffic and fly to the other end of your country.

But this convenience comes at a cost….to the climate. Aviation accounts for somewhere between 2 to 5% of the world’s emissions. And as the world’s desire to travel proves insatiable, the number of planes in the sky each day is only increasing.

The aviation industry has aspirational plans to decarbonise using sustainable and/or synthetic aviation fuels. But these are currently some way off. In the meantime, airlines are offering carbon offsets. Offsets are controversial products and only 1% of passengers pay for them. So, this week on The Climate Question we are asking, can flying ever be climate friendly?

The development of agriculture some 12,000 years ago changed the way humans live.

As technologies have developed we’ve become more and more efficient at producing large amounts of food and feeding an ever growing population, often with the help of synthetically produced nitrogen fertiliser.

These fertilisers can damage ecosystems. They also produce a potent greenhouse gas called Nitrous Oxide which is 265 times more warming than carbon dioxide. It’s estimated that the manufacturing and use of this fertiliser contributes 2% of global greenhouse gas emissions. But is it feasible to ban synthetic nitrogen fertilisers or would that risk plunging the world into mass food insecurity?

Join presenters Qasa Alom and Graihagh Jackson as they journey from an urban garden in Sri Lanka, where a radical fertiliser ban caused chaos, to eastern Africa where Kenyan farmers are mixing tradition with new technology to try and save the world’s climate, and its soils.

Cycling is healthy, cheap - and as modes of transport go, they don’t come much greener. Worldwide, transport is responsible for nearly a quarter of all carbon emissions, with road transport alone accounting for 75% of that. But so far, most discussions on greening the transport sector have focussed on electrifying our cars, trucks and buses – overlooking the vital role that bicycles could play in the climate transition. In fact, experts say that we’re unlikely to meet our short-term climate goals without more people getting on their bikes. So what needs to change to make that happen? We look at what’s been done on streets of Bogota, New York and Kampala to get more people cycling across the world.

Along almost every tropical coastline you can find the tangled roots of mangrove trees, a natural barrier against extreme weather. They are also one of the most powerful weapons we have for fighting climate change. Mangrove forests are six times better at capturing carbon than tropical forests. But in the last 40 years up to a third of mangrove forests worldwide have disappeared.

Scientists estimate that peatlands around the world hold about 350 billion tonnes of carbon. The tropical peatland of the Congo Basin – known as Cuvette Centrale - are thought to store the equivalent of 20 years of US fossil fuels emissions.

BBC Africa Correspondent Andrew Harding has been up to his neck in it, witnessing the work being done by scientists to protect it and what might threaten its future. He also hears a warning from Environment Minister, Arlette Soudan-Nonault, about the choices the Republic of Congo faces between preserving the peatlands and making use of its resources to provide a living for its population.

We find out how one simple lesson learned in Indonesia is being shared with countries in Africa and South America to help keep a global promise to protect tropical peatlands. It’s not just about promises though – financial experts explain why persuading richer countries to pay cash for “wasteland” could be good for all of us.

Reduce, reuse, recycle is a familiar mantra the world over. Recycling has been described as ‘one of the easier climate-friendly acts” that individuals can do. A recent poll found that, globally, most of us believe that recycling is the single best thing we can do to tackle the climate crisis. But there isn’t much mention of “reduce” and “reuse”.

This week, presenters Kate Lamble and Neal Razzell explore how successful the world’s recycling system really is, visiting Port Klang in Malaysia where huge swaths of the globe’s recycling gets sent only to end up... well, listen and you’ll find out! Kate and Neal will also learn how climate friendly recycling really is and whether there are other more important actions we can take to improve how we manage our waste.

We often talk about the physical costs of climate change; the economic fallout, the effect on livelihoods and damage to the earth. But all of the changes to our world caused by global warming will have an effect on our minds, our mental health too. Earlier this year the mental health challenges caused by rising temperatures and extreme weather events were spotlighted in a report by the UN’s climate science body, the IPCC. Anxiety, stress, post-traumatic stress disorder, and even suicide, are all predicted to increase as the world heats up. Jordan Dunbar looks at what this means for people living on the front line of climate change, including examples from Nigeria, India and the Philippines.

Long term climate policy has long been at odds with short-term politics. As numerous countries head to the polls this year, we visit Brazil, Australia and the United States and see how climate policy is being used as a political tool to divide voters.

During recent the elections in Australia – a country with some of the world’s highest emissions per capita – experts believe that experiencing the effects of climate change first hand brought the need for action up the agenda, leading to the unseating of the climate sceptic Liberal National Coalition. We hear from a follower of Brazilian president Jair Bolsonaro, who believes that the country’s own deforestation figures are fake. Meanwhile, in the US, we look at how the Republican party’s position changed from the 2008 presidential elections from proposing climate policies to denying that man-made climate change is real.

Recent research shows that levels of Methane gas in the atmosphere are rising rapidly. It is over 80 times more potent as a greenhouse gas than carbon dioxide so poses a major threat to the world’s goal of limiting global warming to 1.5 C. At COP26, over 100 countries signed a Global Methane Pledge to reduce man-made emissions by 2030 – experts say cutting methane emissions is ‘the most powerful lever we have for reducing warming... over the next 30 years’. So what can be done to stop the levels rising further? We hear how farmers in Bangladesh, along with other parts of Asia, are using wetting and drying techniques in rice paddies to reduce emissions; how cows are being fed special dietary supplements with a surprising ingredient: seaweed, but why naturally occurring wetlands are a cause for concern.

The ocean covers over 70% of the Earth’s surface and can hold more than 150 times the amount of carbon dioxide as air. Around a quarter of CO2 emissions created by human activity each year is absorbed by them. From phytoplankton to whales to seagrass meadows we explore how this happens.

China currently has 53 nuclear power plants with plans to scale up significantly in the next decade, while India is planning to build 10 new power plants over the next three years. South Korea’s new government has committed to restarting its civil nuclear programme and even Japan’s prime minister has pledged to resume nuclear power in a country that has long been resistant.

Following Russia’s invasion of Ukraine, energy security has now become more of a priority with countries looking for alternatives to Russian gas. And as countries transition to renewable power in an effort to reach net zero by 2050, governments are looking for a stable, green power supply which is lower cost. In the latest IPCC report, all pathways recommended nuclear in some form to mitigate against climate change.

After nuclear disasters such as Fukushima in Japan, safety has become an even more pressing issue, both in the region and globally, in the face of a resistant public and to safeguard communities around any power plants. We gained access to the Hinkley Point power plant in the UK which has adapted the design of the reactors to make them safer after what happened in Japan; but the pace of building has been slow and costs have been high. In China, a commitment to build more has led to a coordinated approach in terms of training, the supply chain and funding. But there are challenges ahead.

Presenters Kate Lamble and Jordan Dunbar are joined by Changhua Wu, a policy analyst specialising in China's environment, energy, climate change and sustainable development; Diane Cameron, head of the Nuclear Technology Development and Economics Division at the OECD Nuclear Energy Agency; Edwin Lyman, expert on nuclear safety and proliferation; and Director of Nuclear Power Safety at the Union of Concerned scientists in Washington.

There are over 10 million electric cars on the road globally after a decade of rapid growth, representing around 1% of the world’s car stock. But there are questions about whether there is the infrastructure to match. In many countries there are not enough chargers being installed to cope with the number of electric cars being sold. There are also doubts about whether existing electricity grids have the ability to store enough capacity to cope with charging demand and whether the amount of energy required can be fulfilled by green electricity alone.

This week we look at Norway, an early adopter to electric vehicles, or EVs, and have been through a quick adaption period in which they improved their electricity grid to support night time charging, as well as improving the network of fast chargers around the country to enable EVs to take their drivers long distances.

We then look at Vancouver in Canada has been looking at ways in which they can improve their EV infrastructure, to encourage the public to make the switch away from internal combustion engines. But do they have enough public chargers to serve those without access to their own private driveway?

And finally we take a look at how Sub-Sahara Africa is electrifying motorbikes and minibuses. Many rural communities remain off-grid because demand for electricity is so low that it is not financially viable for them to build the infrastructure. For these rural areas, electric vehicles will bring a solid demand for electricity, bringing the potential for companies to make a profit from introducing solar mini-grids to those communities that don’t yet have electricity.

The renowned climate scientist and IPCC author Maisa Rojas has been making headlines after being appointed as Chile’s new Minister for the Environment. She has pledged to deliver a green, sustainable and resilient future – and a ‘just transition’ to renewables from an economy that has to date been reliant on mining, forestry and agriculture. The legacy of General Augusto Pinochet has cast a long shadow over Chile, so one of the first hurdles is a vote on a new constitution in July which would ease the passage of new climate legislation. The new government of leftist leader Gabriel Boric also faces a divided Congress, and will need to galvanise support for a radical new agenda. Chile has vast potential for solar energy and hydropower, providing the infrastructure is in place to transmit it to different parts of the country. Can the government play a leading role globally in shifting to great dependency on renewables – and closing down coal-fired power stations in the coming decade?

When talking about climate change, the term net zero has become popular with politicians over the last few years. More than 130 countries have now pledged to go net zero to help slow global warming. Reaching net zero means reducing the amount of emissions as much as possible and removing any that remain from the atmosphere. We hear from communities in South Africa, where the government plans to reach net zero by 2050. But the country is heavily tied to coal and faces several challenges around employment and energy security. And while politicians make their net zero announcements, the United Nations projects that emissions will continue to rise even with the current pledges politicians have announced. What does net zero mean and could it help climate change?

As more countries launch more rockets into orbit for commercial and scientific reasons, the space industry is experiencing rapid growth.

It’s on the verge of an even greater increase as space tourism takes off. The International Space Station is now open to tourists and private companies have developed rockets that can be reused – all meaning more launches into space.

But rocket exhausts contain particles that can affect the climate. What are the potential impacts and is it time to apply the brakes to the new space race?

In the wake of Russia’s invasion of Ukraine, parts of the world are so dependent on Russian gas that they have no option but to continue to buy it. This week’s episode looks long term plans for improving energy security, particularly in Europe where the biggest focus is on increasing renewables. Whilst this sounds like great news for the climate, Europe only accounts for 10% of the worlds’ emissions. For fossil fuel rich countries like the United States, energy security policy will mean pumping more oil and gas out of the ground.

We visit Bonny Island in the Niger Delta where business in Liquified Natural Gas is booming to explore how other resource rich countries stand to gain from the increase in oil and gas prices. And ask, as the world makes plans to stop purchasing Russian oil and gas, what will this mean for Russia’s climate policy?

The Russian invasion of Ukraine has been met with harsh financial sanctions. These have come from North America and Europe. The US and Canada have also banned Russian oil and gas, but Europe has found itself unable to do so - even as natural gas prices soar. The EU receives 40% of its natural gas from Russia, and for many countries, if they turn it off, the lights will go out and they’ll be unable to keep themselves warm. As a result European money continues to pay Russia for its natural gas resources.

This episode looks at the short term plans for European countries, dependent on Russian gas, to remove it from their energy systems and ask if this could be the perfect moment to turn away from fossil fuels, including natural gas, and turn toward a much improved renewable energy network?

Scientists say extreme weather is intensifying and becoming more frequent because of climate change and the impacts are causing huge losses.

People living in Brisbane and other parts of eastern Australia dealt with those impacts recently, when heavy rain fell for days - destroying thousands of homes and at least 22 people are known to have died.

Authorities declared it a once in a-100-year-event, making it the second disaster of its kind in the same area in just 11 years. While insurers face losses trying to cover it all, reinsurers say climate change is now a number one risk.

We talk to residents in Brisbane as they clean up after the floods and ask if insurance can be the world’s safety net as the impacts of climate change intensify?

As climate change brings rising temperatures, droughts and shifting patterns of rainfall, animals are adapting to keep pace. Bird’s bodies are growing smaller, their wingspan longer, lizards are growing larger thumb pads to help them grip more tightly in hurricane strength winds, beak size is changing. We visit the Galapagos, where evolution was first discovered by Charles Darwin, and investigate the many ways animals are adapting their behaviour and physiology to survive the impact of climate change. Changes to climate are also influencing animals’ genetics, meaning that we are seeing species evolve within our own lifetime. However, most animals won’t be able to adapt quickly enough to cope with the speed they need to in order to survive in a warming world. Presenters Jordan Dunbar and Kate Lamble look at what role evolution plays in helping animals adapt to climate change.

"A brief and rapidly closing window of opportunity” is how a new major climate change report from the UN described the effect of rising emissions. Already 40% of the world's population is "highly vulnerable" to the impacts, according to the latest report from the International Panel on Climate Change. And it’s all happening much more quickly than previously thought.

Sophie Eastaugh and Jordan Dunbar discuss the findings with a panel of experts. How much more serious do things need to get before action is taken? Produced for the BBC World Service by Darin Graham.

The need to be able to store electricity as part of our low carbon future, has increased dramatically as the use of renewable energy has expanded. Both solar and wind energy rely on sunlight and weather, only providing intermittent power. Electric cars need to be able to travel greater distances on one charge and cost less to have mass market appeal. It’s clear batteries are a key - but evolving - technology. Improvements still need to be made to their safety, power and cost.

Megawatt batteries are being built in many countries, in a step toward creating a renewable energy back-up for the grid. But these batteries are made using Lithium, which is limited because of their size, the length of their lifespan, and their track record in causing fires.

We look at the limitations of the batteries that exist right now, and what new technology in the field is expected to bring in the coming 10 to 15 years. We also visit a hydro-pump powered energy storage system in Israel, where the company, Augwind, is developing an interesting alternative to electric batteries.

We hear a lot about how melting glaciers are contributing to sea-level rise but not so much about the impact inland. In places like Tajikistan, glaciers feed rivers and are a significant water source.

As they melt climatologists expect water flows to increase, contributing to a rise in mudslides and floods. But in the long term, the melting ice will lead to water shortages.

We look at mountain communities living near glaciers and try to understand what impact this is having now and what might happen in the future. What can we do to prepare for the consequences of glacier melt?

For nearly a century, governments around the world have measured the health of their economies by a single metric: GDP, or Gross Domestic Product. It measures a country’s economic growth, and over the years has become a shorthand for national progress; a rising GDP is generally understood to mean more people in work, more companies in business, living standards on the rise. Yet, as experts have argued for decades, there is a lot that GDP leaves out. While it measures the value of all goods and services produced and consumed in an economy, it doesn’t account for nature, wellbeing, or planetary health. To GDP, a 100-year-old carbon capturing tree is worthless until its chopped down and sold as timber. Cleaning up after disasters, such as extreme weather events, improve GDP due to the increase in spending - even as people and planet suffer the consequences. In an age of climate breakdown, many economists are arguing that our obsession with GDP is damaging the planet. So is it time to ditch GDP as a measure of progress and come up with a new metric that puts sustainability at its core?

Ahead of COP 26, a rush of businesses declared their commitment to “net zero” emissions targets. But concerns were raised about how credible these targets were. Critics pointed out that many companies’ plans did not require them to change behaviour any time soon, or be held accountable for realising them - and that some of their promises just weren’t good enough. In this edition of The Climate Question, Kate Lamble and Jordan Dunbar ask how much can we believe in companies’ promises on climate?

At the UN climate summit in Glasgow last year, China and the United States announced they will work together on reducing greenhouse gas emissions.

Experts say this is a significant move because China and the United States are the two largest economies and polluters.

China emits the most greenhouse gasses, around 27% of global emissions, but it is walking a narrow path between its energy crisis and its commitment to climate work.

There are reports of plans to build up to 80 new coal power plants.

Without China acting, attempts to keep global temperatures down will not work.

How committed is China to climate change?

Written into many of the promises made by countries about how they intend to achieve their UN climate pledges to reduce emissions is an assumption that technology will help them make this happen. But this technology either does not currently exist or is in its infancy.

This includes schemes to take carbon out of the air via carbon capture and storage or direct air capture and to replace our dependency on fossil fuels with green hydrogen. We visit the world’s largest direct air capture plant in Iceland and speak to the person in charge of Namibia’s grand plans to become the green hydrogen production hub of the world - can both really be scaled up in order to meet our current needs?

Everyone who steps outside can appreciate the value that the natural world brings to our lives.

To some people, the idea of placing a monetary value on trees and mangrove forests is wrong because nature and its gifts are priceless. But others say the love of nature has not stopped it from being polluted or destroyed.

The natural world plays a major role in capturing the carbon from our atmosphere. A marketplace now exists where countries and big business can pay others to protect their forests, swamps and bogs in return for offsetting their emissions.

Could giving nature a dollar value make us care about it more and help us fight against climate change?

Billions of dollars are being invested in electric vehicles in the name of fighting climate change. World leaders are backing them as the green fix for our burgeoning road transport emissions. But when you factor in the carbon emissions that come from manufacturing EVs, how well do they stack up against their petrol and diesel counterparts? If all the cars on the road switched to EVs, could we meet our climate targets? This week The Climate Question looks under the bonnet of electric vehicles – and whether there is an altogether better solution.

For centuries, we’ve been reading, watching and listening to science fiction. And all too often, it’s pretty pessimistic about our future, especially when it touches on the topic of climate change. This is leading some to ask whether these doom and gloom stories are doing the climate fight more harm than good - causing us to feel so anxious and powerless that we don’t take action. So for this week's climate question, Graihagh Jackson is asking: Is sci-fi holding us back? First broadcast on 5th April 2021.

Images are a key part of communicating climate change, and shape how we understand the crisis unfolding around us. But while lots of research has been done into the language we use to talk about climate, images are often left out of the conversation. As a result, over time, a limited set of images have come to dominate how we think of climate change – like polar bears and melting glaciers - which haven’t kept up with the changing conversation about the crisis. All too often, these images tend to be abstract, removed from our daily lives and typically don’t feature people - when we know that climate change is happening all around us, all the time, and is very much a story with people and communities at its core. So how can we develop a new, and more effective visual language for climate change? What kind of images ‘work’ to both convey the urgency of the crisis as well as inspire behavioural change? And what are some of the ways in which photographers are seeking to represent the crisis in a way that transforms apathy into action?

For decades scientists have warned us about the risks of climate change. Yet humans are badly psychologically designed to face up to the challenge of changing our behaviour. Research shows that constant threats of impending doom make us hit the snooze button rather than waking us up. And our evolutionary shortcomings mean we respond to the threat of immediate danger rather than what might happen in the future. So what can actually work to help us change our status quo?

If there were fewer of us, would the amount of greenhouse gasses we emit reduce? It’s a question that often creeps up in discussions about climate change. Studies show that the global population will decline eventually and populations in many rich nations are already declining. However, 11,000 scientists signed a paper warning of “untold suffering due to the climate crisis” unless society transforms, including the reversal of population growth. But an analysis by the United Nations found that affluence has a greater impact on the climate than population. When we talk about overpopulation, what are we really saying and where does the conversation go from here?

The journey from catwalk, to wardrobe, to landfill is getting shorter and shorter. Our demands for fast fashion mean around 100 billion garments are produced every year. We’re buying more, then wearing them less often. Many will end up in the trash. Not only that, there’s been a big growth in clothes being made out of synthetic materials originating from crude oil.

In 1985 British scientist Jonathan Shanklin and colleagues published a study that shocked the world. The study revealed a hole in the Earth’s atmosphere right over Antarctica. It had been caused over time by chemicals known as CFCs, used in things like fridges, air conditioning units and aerosol cans. These were destroying the layer of ozone in the stratosphere which protects us from most of the sun's ultraviolet radiation - without it, cases of skin cancer would soar. Less than two years after the discovery, world leaders signed an agreement called the Montreal Protocol, committing to phase out CFCs. It has been described as the most successful international treaty of all time - every UN country has signed up, and ozone is expected to return to its previous levels around the middle of the century. So what can we learn from how we tackled the ozone hole in how we address climate change?

Around the world a growing number of rivers, mountains, nature reserves, even marshes have all been given legal rights. It’s an idea that’s being tested in courtrooms around the world.

Climate negotiators from all over the world are gathered in Glasgow for the global summit to discuss how we can curb the worst effects of global warming. The Conference of Parties (or COP26) has now reached its half-way point. Kate Lamble and Neal Razzell take the temperature on what has been discussed so far.

This week will bring around 25,000 world leaders, business people, policy shapers and campaigners together in Glasgow for COP26, a global climate summit that’s seen as a crucial moment in the fight to curb global warming. Among them will be young activists who in the last few years have made global headlines with the School Strike for Climate movement. Beginning with Greta Thunberg in Sweden in 2018, millions of young people have taken to the streets to try to get their voices heard. We hear from three young people devoted to climate activism. In the Philippines, Mitzi Jonelle Tan grew up amid severe typhoons that would flood her bedroom. In India, Disha Ravi saw her grandparents struggle to get enough water for their farm. And in the United States, 19-year-old Jerome Foster has been invited to join President Biden’s Environmental Justice Advisory Council. Do these young activists feel their voices are being heard? What action do they most want to see from world leaders at COP – and how realistic are their demands? Presenters Kate Lamble and Jordan Dunbar talk to Disha Ravi, Mitzi Jonelle Tan, Jerome Foster and the BBC’s Environment Correspondent, Matt McGrath.

World leaders are gathering in Glasgow for a global climate summit to agree on how to further limit the threat of global warming. Experts say the conference, known as COP26, could be the last chance for governments to agree on a way to cut global emissions in half by 2030. It’s also an opportunity to assess how well they have been doing with previous targets to prevent average global temperatures from rising beyond 1.5 degrees Celsius, agreed at a big climate meeting in Paris in 2015. According to the Climate Action Tracker, The Gambia is thought to be one of the only countries with plans in line with 1.5 degrees. What further commitments will leaders from the rest of the world arrive with at COP26 and what will it take for countries to keep those climate promises?

Russia is the world’s fourth-largest emitter of greenhouse gasses. Any talk of changing that needs to focus on President Vladimir Putin. Under his leadership, Russia has become a fossil fuel powerhouse. Since he took office in 2000, Russian oil production has risen by 70%. Today, the state is dependent on its revenues. Four in every ten dollars Moscow spends comes from fossil fuels. So the idea that Russia needs to shift away from fossil fuels to prevent the worst effects of climate change strikes at the very heart of Mr Putin’s power.

But Russia is already suffering more than most from the effects of climate change. Arctic temperatures are rising faster than the global average, forests the size of countries are going up in smoke. Two thirds of the country’s permafrost - permanently frozen ground - has roads, homes, schools, oil and pipelines and even nuclear reactors are built on it. And the permafrost is starting to melt. Putin’s latest national security document for the first time mentions climate change as a risk. But can he do what is necessary to prevent things from getting worse?

There are thought to be over 10,000 gas flares around the world that contribute to global warming by emitting tonnes of carbon dioxide and methane. Flared gas is a by-product of oil extraction and is frequently used as a method of eliminating unwanted gasses in countries such as Albania, Algeria, Libya, Iraq, Russia and Nigeria. Yet, year after year deadlines set to stop the practice are missed. The oil industry says better infrastructure is needed to stop flaring and some of the world’s largest producers of oil have committed to ending flaring by 2030. What will it take for that to happen? Presenters Neal Razzell and Kate Lamble are joined by: Bjørn Otto Sverdrup, chair, Oil and Gas Climate Initiative Mark Davis, CEO of Capterio.

Recent research has shown that oil companies knew about the threat of climate change decades ago. Yet over forty years, it has been revealed that they contributed millions of dollars to think tanks and campaigns to spread doubt and misinformation about climate change – its existence, the extent of the problem, and its cause.

Across the US, these revelations have sparked a wave of lawsuits against the fossil fuel industry, demanding accountability for climate change – and now a US congressional committee has started to investigate. Executives from the world’s biggest oil companies and trade groups have been called to testify before US lawmakers in October this year, in an inquiry modelled on the tobacco hearings of the 1990s, which paved the way for far tougher nicotine regulations.

This week, The Climate Question looks over the evidence behind these allegations – and asks whether Big Oil might finally be facing a reckoning for its role in the climate crisis.

Presenters: Neal Razzell and Phoebe Keane Producer: Zoe Gelber Series Editor: Ros Jones Editor: Emma Rippon

Heatwaves and floods are becoming more frequent around the world. But are the homes being built today taking that into account?

The Climate Question considers the impact that living in a building threatened by rising water or constructed so that you bake in the heat has. And it asks why planners and developers in many countries have been so reluctant to adapt. Where are lessons being learnt and will other places follow their lead?

For decades, around the world, climate change coverage has been thin. Guests discuss why the media in petrol states, in particular, have struggled to tell that story. Science illiteracy in newsrooms has led to a mixture of climate silence and false balance in print and on air. But, even when the science has not been contested, the way the crisis has been reported may have caused audiences to turn away. Can climate coverage learn lessons from how that other hugely consequential science story of our time – the pandemic - has been told?

If we are to ensure that there’s no more than a 1.5 degrees centigrade increase in global warming, the International Energy Agency recently stated that oil exploration must stop. A few countries have heeded that warning but the vast majority have not. The Climate Question hears from two nations – one already rich from oil, the other poor and yet to benefit from recent oil finds – about why they are continuing to explore. But, even for those who are following the IEA’s advice, will stopping be straightforward or might hurdles still lie in wait?

As extreme weather events become more frequent and intense, the developing world says urgent action is needed to avert catastrophe.

Some in the developing world say that as richer countries caused the bulk of global emissions, they should compensate them for the losses and damages caused by the climate crisis.

But will delegates, negotiators and politicians gathering at the international climate conference, COP26, in Glasgow in November take notice?

In previous years rich countries have been reluctant to agree to compensate poorer countries. If that happens again, what will the impact be on reaching a global commitment to reduce emissions?

Another chance to listen to an episode that asks whether we can change our ways. Drastic change is needed to limit the increase in global temperature caused by climate change. More than two-thirds of greenhouse gas emissions worldwide result from how we live our lives. But the behaviours that drive these emissions tend to be deeply habitual and hard to shift - the way we heat our homes, what we eat and how we travel to work. And our behavioural good intentions all too often fail to translate into action. So our climate question this week is how we can be nudged, or even shoved, to change?

A diplomatic deadline looms as new science urges faster action. Can nations respond? So far, the answer has been ‘no.’ Three decades of international talks to reduce greenhouse gas emissions has left them higher than ever and set to rise further. We provide a brief history of climate talks, with an eye on what can be learned ahead of the next round, called COP26, in Glasgow.

Hydrogen gas has long been recognised as a potentially valuable tool for tackling climate change. The most abundant element in the universe, it is also a clean-burning gas and – in theory – could be used to power almost anything, from our cars and homes, to planes and ships, to agriculture and heavy industry.

We already produce millions of tons of hydrogen each year for use in the chemicals industry, by extracting it from natural gas - a process which emits CO2. But hydrogen can also be made by splitting water molecules with electricity – and when that electricity is powered by renewables it comes without a carbon price tag.

It is this so-called ‘green hydrogen’ that is currently generating hype around the world as the ‘fuel of the future’ and the missing piece of the decarbonisation puzzle. Across the world, governments are announcing far-reaching hydrogen strategies. Fossil fuel companies, too, are investing big, hoping to cash in on the ‘hydrogen boom’.

But for all the talk of green hydrogen as a miracle fuel, it has a long list of drawbacks too. It is expensive, difficult to store, inefficient and explosive. Previous hype cycles around hydrogen have ended in failure for a combination of these reasons. So while experts agree that hydrogen does have a role to play in decarbonisation, the question is – how big should it be? And are we about to spend hundreds of billions of dollars on a white elephant?

Climate change is going to shape young people’s lives, and yet many students feel their schools are not equipping them with the knowledge and skills to face this future. Teachers aren’t always confident broaching climate change in the classroom. And governments have been slow to get comprehensive and compulsory climate change education onto national curriculums.

But how do you teach young children about something so big and scary? And how should adults deal with the hopelessness that some young people feel when faced with a crisis they feel powerless to change? This week, we’re going to Ghana, the US, China, the UK and Europe to find answers.

It's estimated that 9 out of 10 items sold in our shops are shipped halfway around the world on ships. The resulting emissions amount to around 3% of the global total, more than many countries, but we rarely hear about the role shipping plays in the climate crisis.

Partly this is because most of shipping's pollution occurs far out at sea, out of the sights and minds of many consumers - and largely out of the reach of regulation. Like aviation, ships travel across borders, so their emissions are not attributable to any one country.

There's no simple fix to shipping's climate problem. Currently most ships use one of the dirtiest forms of fossil fuels, known as 'bunker fuel' - because it's plentiful and cheap. And they use a lot of it - 300 million tonnes per year. But there are alternatives out there. Hydrogen, sustainable bio-fuels - even wind power - are all possible, so why aren't they already being used? What will it take to turn the shipping industry around?

The heatwave that hit parts of the west coast of North America shattered records by several degrees. It affected parts of the United States and Canada that were unused to extreme heat. Hundreds of people died and emergency teams were pushed to their limits. In Lytton, Canada, temperatures reached 49.6 degrees celsius. Days later, the entire village burnt down.

Scientists say that climate change had made this heatwave 150 times more likely. They also warn that, if global warming continues, about one-third of the world’s population will become threatened by extreme heat.

So does our attitude to extreme heat need to change?

You don’t often hear climate change and football mentioned in the same sentence, but rising temperatures are set to disrupt every area of our lives, the ‘beautiful game’ included. Heat and other extreme weather have already been affecting training and matches, which experts say we can expect a lot more of in coming years. But not only is the sport at risk from the climate crisis, it’s also a significant contributor to it. The operation of multi-thousand capacity stadiums, spectator travel and merchandise, not to mention the fossil fuel sponsorship that props up professional tournaments, mean that football is currently part of the climate problem. Yet football also has an audience of billions – all potentially affected by climate change – who could be part of the solution. Featuring footballers and fans, we ask if football can tackle its carbon problem and be a force for good in the fight against climate change.

Freshwater sources around the world are becoming more irregular, and disputes between countries are common, with fears that access to water could eventually lead to conflict.

There’s a high-profile case going on right now in northeast Africa, where talks about a huge new dam on the Blue Nile in Ethiopia have stalled. Ethiopia says it needs the hydroelectric dam to help solve some of its power supply problems. However, the Blue Nile is the largest source for the river Nile, which runs through Egypt, and there are concerns there that the dam will have huge consequences for people living further downstream.

According to the United Nations, around two-thirds of rivers shared by two countries or more lack formal agreements on how to manage the water.

So how can we help countries reach agreements over equal access to water, and ensure they stick to them in the future?

Australia is one of the world's biggest per-capita greenhouse gas emitters, and a Climate Question listener wants to know why the world isn't demanding her country do more.

Jodie lives in tropical Queensland, which she says is 'paradise', but it's also a place affected by bushfires, drought, and cyclones.

Prime Minister Scott Morrison says 'Australia can always be relied upon' to deliver action on climate change, but critics at home and abroad point to a record of over-promising and under-delivering.

Observers also blame the country's powerful and profitable fossil fuel industries as a reason why the Australian government has been slow to make progress.

But is it time, as listener Jodie asks, to give her country a 'a kick up the bum'?

The Brazilian legislature is currently considering a bill that would legalise the private occupation of some public land in the Amazon region - a move that would most likely lead to further deforestation. But could renewed international pressure from foreign governments and corporations demanding protection of the Amazon convince the Brazilian government to rethink its policies, or will they simply go ignored, as it favours short-term economic gain over long-term environmental protection?

It’s likely that there will be no successful green transition without an element of carbon capture, storage and re-use. The oil industry has been burying CO2 underground since the 1970s, so the infrastructure and technology is already available, but removing CO2 from the air at scale is new, and the companies doing it are small. We head to an experimental ‘direct air capture’ plant in Canada to hear how they are making fuel out of air, and explore what changes will be required to ensure that their industry becomes a significant one in the years to come. But if we think that a technology fix is out there, might we limit other efforts?

Cities emit around three-quarters of the world’s greenhouse gas emissions, according to the United Nations, and over half of the world’s population now live in one. Many have set ambitious targets to slash and offset their emissions, in the hope of neutralising their impact on the environment and slowing climate change. Some are aiming to do this very soon. Copenhagen’s goal is 2025. More than 700 others have committed to targets over the following decades. But how does a city, choked with traffic and packed full of buildings that require huge amounts of energy, actually go about achieving carbon neutral goals?

Scientists agree that cutting carbon emissions as soon as possible is key to tackling global warming. But as emissions continue to rise, some are now calling for more research into measures that could be used alongside decarbonisation, including – controversially – what’s known as ‘solar geoengineering’ technologies. One idea being considered is spraying light-reflecting particles into the atmosphere to temporarily cool down the earth. It may sound far-fetched, but the idea is based on naturally observed effects following volcanic eruptions. Scientists are now asking whether we could mimic those effects to avoid the worst climate impacts. But research into this technology is not without opposition. A recent solar geoengineering experiment in Sweden got cancelled following a fierce backlash from indigenous and environmental groups. Many say tampering with the climate in this way is too risky to ever try in the real world. So how does solar geoengineering work? What are the risks? And will we ever have to use it?

More than two thirds of our planet is covered by the oceans, but there’s still much to be uncovered about the role that these watery worlds play in climate change. But recent scientific research claims that bottom trawling, a method of fishing that involves dragging heavy nets across the seafloor, emits about the same amount of carbon annually as aviation. Seabed sediments, which act as huge carbon sinks, are churned up, resulting in carbon dioxide emissions. So should trawling – commonplace around the globe because of its effectiveness – be reduced? And has the climate change impact of bottom trawling been exaggerated?

South Korea’s economic development has been the envy of many nations: from war, famine and poverty to one of the richest countries on Earth, all within just a couple of generations. In 1955, gross domestic product was just $64 per capita. Last year, it was $31,000. But this growth was turbocharged by fossil fuels, and has come at a high environmental price. Seventy percent of the power generated in the country comes from fossil fuels and, compared to many rich nations, its commitment to renewables is small. Is South Korea a hero of economic growth or a climate villain? And should developing nations still look to the country as a model to follow?

Indigenous people represent only about six percent of the world’s population, but they inhabit around a quarter of the world’s land surface. And they share these regions with a hugely disproportionate array of plant and animal life. According to the UN and the World Bank, about 80 percent of our planet’s biodiversity is on land where indigenous people live.

Global climate policy has however been slow to recognise that indigenous knowledge - built up over centuries - is worth listening to. This is despite the fact that sometimes in very remote areas, where scientific and meteorological data is lacking, this knowledge may be all there is. Indigenous knowledge can provide valuable insight into what adaptations have worked in the past, and so provide an important guide to the future.

What are the barriers to bringing indigenous knowledge out from the margins of climate research and policy, and can they be overcome?

From fruit rotting in fields, to retailers turning down funny shaped vegetables, and consumers scraping leftovers into the bin, food waste is everywhere. It’s estimated that around a third of all our food ends up not being eaten. If we could sort this, total greenhouse gas emissions would reduce by around eight percent. To put that in context, the only countries that are responsible for emissions of that size are China and the US.

So, what can be done? Graihagh Jackson and Jordan Dunbar discuss fixes - big and small - and hear from a farmer in Morocco turning apples that would otherwise rot into vinegar. The first thing that needs to happen for change to start is for governments to properly count the climate cost of food waste. And that, it seems, is a long way off.

More companies are rolling out carbon dioxide emission labels on products to help us make greener choices. Unilever, the global consumer goods giant, recently announced it is committing to put carbon footprint information on 70,000 products, while multi-national companies Oatly and Quorn have already started adding labels like this to their packaging. But this is not the first time companies have tried this. In the 2000s, for example, an international supermarket put carbon labels on hundreds of products, but cancelled the project after a few years. Why are carbon labels coming back now, and what does this information really tell us? How do you measure the carbon footprint of a product? And will this drive behaviour change and help the environment? Presenters: Neal Razzell and Graihagh Jackson Producer: Darin Graham Researchers: Zoe Gelber and Olivia Noon

President Biden has invited the world’s major polluters to a summit on Earth Day (April 22nd). It may be the biggest climate summit ever organised by an American leader. On the campaign trail last year, Mr Biden said climate change was his “number one issue.” Now, the pressure is on for him to make a big announcement.

But while the US has rejoined the Paris Climate Agreement, it has no official plan to hit the Paris targets. Frantic work is underway in the US to come up with something that satisfies the President’s lofty campaign rhetoric but can actually get through America’s polarised, gridlocked political system.

Ahead of the summit, The Climate Question is reaching out to climate diplomats and experts from China, Bangladesh, the EU and beyond, to hear what the world expects from the US on climate change.

Cities, money, roads, beef burgers and telephones, in fact pretty much all of human civilisation as we know it, would probably not exist were it not for one simple invention. The plough. This humble yet revolutionary tool enabled us to cultivate vastly greater amounts of food than our hunter gatherer forefathers giving rise to villages, cities and empires. But it has come at a cost. Nearly 10,000 years of cultivated agriculture have released billions of tonnes of carbon from the soil into the atmosphere. Just within the EU, it’s estimated 5% of current greenhouse gas emissions come from agricultural soils. That’s more than aviation and shipping combined. Around the world an increasing number of farmers are adopting new methods without the plough to restore soil health and lock more carbon into the ground. But some scientists are questioning whether the potential for carbon sequestration into the soil is being over hyped. What’s more, for millennia the plough has been a crucial ally in boosting yields and in the coming decades we are going have to produce lots more food to feed the growing global population So the Climate Question is; Is it time for us to ditch the plough?

For centuries, we’ve been reading, watching and listening to science fiction. And all too often, it’s pretty pessimistic about our future, especially when it touches on the topic of climate change.

This is leading some to ask whether these doom and gloom stories are doing the climate fight more harm than good - causing us to feel so anxious and powerless that we don’t take action.

So for this week's climate question, we’re asking: Is sci-fi holding us back?

Bangladesh is a country that is exceptionally vulnerable to climate change. With a low elevation and high population density, as well as poor infrastructure and an economic reliance on farming, it is naturally susceptible to extreme weather. The intensification of conditions due to climate change means more people are being driven from their homes and land by sea level rises, storms, cyclones, drought, erosion, landslides, flooding and salinisation of the land. It's estimated that by 2050, one in every seven people in Bangladesh will become a climate migrant. But Bangladesh is far from being alone. Across South Asia, it’s estimated that more than 40m people will be displaced; worldwide, the figure runs into the hundreds of millions. Climate migration is coming. The question is, what are we going to do about it?

A Peruvian farmer is suing a German fossil fuel company, the city of Baltimore has filed a lawsuit against 26 oil and gas firms, and a Polish coal mining company was taken to court by its own shareholders.

As the world becomes more populous, experts say we’re likely to use 25 percent more concrete in the next decade.

The rise of renewables is good news for the climate, but for millions of families who rely on fossil fuels for a paycheque, it means big changes.

People have been talking about a “just transition” for decades. The term was first used in the 1990s, when US unions were demanding help for those who'd lost their jobs because of tightening environmental laws. Now it means looking at how we decarbonise our economies around the world, without leaving certain people behind. Neal and Graihagh hear from Craig, Colorado, as it plans for the shut down of its coal mines.

They also hear from the Middle East and North Africa, where countries have relied on oil and gas for their economies. The money from fossil fuels has kept an instable region together in the past, so what happens when that money runs out?

Drastic change is needed to limit the increase in the global temperature caused by climate change. More than two-thirds of global greenhouse gas emissions come from how we live our lives. But the behaviours that drive these emissions tend to be deeply habitual and hard to shift - the way we heat our homes, what we eat and how we travel to work. And our behavioural good intentions all too often fail to translate into action. So our climate question this week is how we can be nudged, or even shoved, to change?

It seems we all love trees. Politicians, celebrities and big businesses love trees too. They’re seen as a natural climate fix because they eat carbon dioxide, one of the main gases that cause global warming.

The number of trees pledged in the coming years runs into the billions. Pakistan wants to plant more than three billion trees in the next couple of years. Ethiopia claims to have planted 350 million in one day! Neal Razzell and Graihagh Jackson try to see the wood from the trees amongst all these claims, and discover that a ‘forest’ planting campaign doesn't always end up creating the natural woodland we imagine it to be.

And to add to the urgency of the climate crisis, there's a new problem - a warming world may mean plants can’t suck up our carbon dioxide as effectively. Have we planted too much faith in trees?

When a man sitting on nearly $9 trillion dollars of funds speaks, CEOs, investors and politicians listen.

In late January, Larry Fink, boss of the world’s largest hedge fund, BlackRock, announced in his annual letter that "climate risk is investment risk. But we also believe the climate transition presents a historic investment opportunity.”

He's not alone in championing big money's green awakening, but the titans of finance remain invested in the fossil fuel industry to the tune of hundreds of billions of dollars. So does the rhetoric marry with reality?

The big tech firms of the world have reported record profits during lockdown. These firms are some of the industrial titans of the digital age.

Their ability to manipulate vast quantities of data is revolutionising, well, everything. From streaming games and movies, to automating mining operations, controlling medical devices and even simple emails, the internet has brought incredible advances right across the globe.

But we now know that previous industrial revolutions placed a huge burden on the planet. Our climate question this week is: Will this one be any different?

Africa has an electricity crisis. Hundreds of millions of people lack cheap, steady supply, crippling lives in countless ways. Every other continent has electrified off the back of fossil fuels but Africa, on the face of it, has the opportunity to do it differently. Researchers found that some 2,500 power plants are planned across the continent. But the majority are expected to run on fossil fuels threatening to lock Africa into dirty energy for decades. In this edition of The Climate Question, we ask: What would it take to bring clean power to every African? For answers, we have one of Africa’s leading experts on power. Damilola Ogunbiyi ran the Lagos power authority before taking over efforts to electrify Nigeria’s rural communities. Today, she’s the CEO of Sustainable Energy for All and the Special Representative of the UN Secretary-General for Sustainable Energy for All. We are also joined by Tony Tiyou, the Cameroonian CEO of the firm Renewables in Africa. And we hear from a community in Nigeria where people just want the lights on, now.

Lockdown saw historic drops in global emissions in every sector, except one: sports utility vehicles, or SUVs. They are among the best-selling cars in markets around the world, from India to China, South Africa and Germany. But these vehicles pollute much more than a normal sized car, and require more fuel to move and energy to make. Seen as a status symbol and wrongly thought of as safer than other cars, what can we do to wean ourselves off this polluting vehicle?

Featuring World Service India reporter Arunoday Mukhardji; New York Times Shanghai editor Keith Bradsher, author of High and Mighty: The Dangerous Rise of the SUV; Jillian Anable, Professor of Transport and Energy at the Institute for Transport Studies, University of Leeds; and Jim Holder, editorial director, Haymarket Automotive.

Ugandan activist Vanessa Nakate is on a mission to make sure Africa is listened to on climate justice.

In early 2019 she started taking to the streets of Kampala to protest about climate change. It was a lonely pursuit. She was often on her own, or at best with a couple of her siblings or friends. But she quickly started gaining recognition, and has since spoken at the UN and Davos.

However, a year ago she was thrust into the spotlight for all the wrong reasons when the Associated Press cut her out of a photo with four other white youth climate activists at an international climate conference. That painful experience has since informed her activism and role within the climate movement: "We will not have climate justice without social and racial justice", she says.

So, of all the problems the African continent is facing, why did she choose to raise her voice on climate change - and is anybody listening?

As sea levels rise due to global warming, what does the future hold for our coasts?

Already threatened by rising tides, Jakarta, the capital of Indonesia, is in a perilous situation - it is sinking. We join reporter Resty Woro Yuniar on a crumbling sea wall to hear the reality of living under sea level, and speak with the engineer responsible for fighting flooding from both the sea and the mountains. We hear about plans to abandon the city as a capital, and try again on drier land.

Author Jeff Goddell describes being next to the glacier that could show just how high the oceans could rise. Solutions in the past have involved building our way out of this problem, but some locations will be too expensive to save. Is Jakarta a warning to us all?

Five years ago, there was widespread celebration after world leaders signed up to the Paris Agreement. However, despite pledging to pursue efforts to limit global warming to just 1.5 °C above pre-industrial levels, emissions have continued to rise. Many are saying the COP26 conference in late 2021, where world leaders will meet again, is a make-or-break moment to turn words into action. What needs to be achieved? What is the cost of failure? And where are the signs of hope for success?

Justin Rowlatt and Navin Singh Khadka talk to Laurence Tubiana, CEO of the European Climate Foundation (ECF), who was previously France’s climate change ambassador and special representative for COP21, and a key architect of the landmark Paris Agreement. They are also joined by Christiana Figuerres, who was Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC) between 2010 and 2016, and Dr Emily Shuckburgh, director of Cambridge Zero at the University of Cambridge, and reader in environmental data science at the Department of Computer Science and Technology.

In 2015, Pope Francis asked Catholics the world over to protect our planet. But five years on, with emissions and extinctions rising, what difference has it made? And have any other religions followed suit? For answers, Neal and Graihagh are joined by two leading voices on the environment: Christiana Figueres, who helped the world reach the Paris Climate Agreement, and Cardinal Peter Turkson, the Pope’s leading climate advisor. They’ll hear evidence from Poland, a Catholic country that runs on coal and where Church leaders are not always in step with the Vatican’s teaching on the environment. They’ll also assess the global impact of the Pope’s green push, and talk about the role of faith in fighting climate change. Produced by Anna Meisel and Eleanor Biggs Editor: Ravin Sampat.

Climate scientists have shifted the definition of what they believe is the "safe" limit of climate change. Researchers argued the global temperature rise must be kept below two degrees Celsius by the end of this century to avoid the worst impacts of climate change. But what are those worst impacts in reality? What does it mean to people, communities and the world we live in? In this episode, we go to the people who see the effect of the rising temperature in their daily life.

Many people have worried that the Covid-19 pandemic meant the harm of climate change was being ignored. But could the opposite be true? Neal Razzell and Graihagh Jackson look at the links between both emerging pandemics and deforestation. We’ll be on the ground in Nigeria, with BBC reporter Nkechi Ogbonna showing us the reality of farming and land use change in the tropics. While in the bush, she meets an illegal logger to find out their take on climate change and pandemics.

Professor Thomas Gillespie studies emerging infectious diseases, the types we don’t even have a name for yet. His work has shown the problems of land use change for mining and agriculture and the emergence of diseases that jump from animals to humans, like Covid-19. The more we cut down, the closer we get to diseases we’d never encountered before. We also hear about global solutions from World Service environment correspondent Navin Singh Kadhka, and how we can help in the fight to save the rainforests.

Will a Joe Biden presidency be better for the environment than President Trump’s policies? Is China really set to take the lead on tackling climate change?
