WORLD: we got this with Esau Williams

A recent assessment found that the area of Earth's landmass that will be too hot for even healthy adults to keep a safe core body temperature will approximately triple - to an area almost the size of the US – if global warming reaches 2°C above the preindustrial average. We've already reached 1.5°C.This week Esau asks: what does 'too hot' actually mean? What will happen to the people who live in these areas? And what might be done to help combat the impacts?Joining him are Dr Tom Matthews, lead author of the study and Senior Lecturer in Environmental Geography, and Aditya Pillai, who is a doctoral researcher in King’s India Institute, a Visiting Fellow at the Sustainable Futures Collaborative, New Delhi, and author of a recent report investigating India’s readiness for the extreme heat of a much, much hotter world.
