The real import of climate scientists’ work cannot be captured in simple headlines which obscure the complex regional distribution and variations in the impacts of global warming. Learning that an increase of more than 1.5°C in global temperature above pre-industrial levels is now unavoidable tells us nothing about the pertinent effects on Southeast and East Asia, for example.
