Global heating will push billions outside ‘human climate niche’
The world is on track for 2.7°C of heating with current #climateaction plans. This would mean 2 billion people experiencing average annual temperatures above 29°C by 2030, a level at which very few communities have lived in the past. Up to 1 billion people could choose to migrate to cooler places. In countries with large populations & already warm climates most people will be pushed outside the human climate niche, with India & Nigeria facing the worst changes. Photo: Street market in India
