Sea change: a talk with UN Special Envoy for the Ocean, Peter Thomson

Our oceans absorb 30% of the CO2 caused by greenhouse gas emissions. And they take in 90% of the heat that's caused by the same emissions. But our oceans are getting tired. UN Special Envoy for the Ocean, Peter Thomson, talks to us about ocean biodiversity, coral reefs and acidification. And the miracle of intertidal marshes, seagrass beds, lagoons, and mangrove forests. Host: Clara Young Producer: Robin Allison Davis Get the latest OECD content delivered directly to your inbox!
