This image breaks me. At 2.7 degrees of warming, which is our present policy trajectory, two billion people will be exposed to extreme heat.
99.7% of those people live in the global South. People who have done nothing to cause this crisis. The injustice is staggering.

Yes, Southern Europe and other regions shaded grey here will face extreme heat at 2.7C (and already are even at 1.2C). Grey does not mean OK. This study is focused on serious extremes, like 80+ days per year with max temps above 40C.

I should say: for most of the affected countries, their cumulative emissions are still within their fair-share of the safe planetary boundary of 350ppm concentration of atmospheric CO2. (This map updates this study to 2019: sciencedirect.com/science/ar…)
