As Europe experiences another record breaking heatwave, we look at the science of attribution. Usually it?s a long time after extreme weather events that scientists gather enough data to make a judgement on the influence of anthropogenic forces, such as man-made climate change.
However climate experts at a meeting Toulouse France, experiencing the worst of the heatwave, are crunching the data right now, to see if they can quantify the influence of climate change on this heatwave as it happens.
Also we find lakes of fresh water hidden ? under the sea, find that Neanderthals went west and discover how spiralling laser light may be used to control a new generation of microelectronics.
