New research predicts a significantly drier world if global warming reaches 2ºC. Over a quarter of the world’s land could become significantly drier and the change would cause an increased threat of drought and wildfires. Limiting warming to under 1.5ºC would dramatically reduce the fraction of the Earth’s surface that undergoes such changes. Areas which would most benefit from keeping warming below 1.5ºC include Central America, Southern Europe, Southern Australia, parts of South East Asia, and Southern Africa.
