Identifying climate impact hotspots across sectors

One out of ten people on Earth is likely to live in a climate impact hotspot by the end of this century, if greenhouse gas emissions continue unabated. Many more are put at risk in a worst-case scenario of the combined impacts on crop yields, water availability, ecosystems, and health, according to a study now published online by the Proceedings of the National Academy of Sciences (PNAS) including BGC-author Ryan Pavlick. It identifies the Amazon region, the Mediterranean and East Africa as regions that might experience severe change in multiple sectors.
