Global heating a serious threat to the world's climate refuges, study finds

Biodiversity hotspots with millions of years of climate stability could be among the world's hardest hit regions

Biodiversity hotspots that have given species a safe haven from changing climates for millions of years will come under threat from human-driven global heating, a new study has found.

Species that have evolved in tropical regions such Australia's wet tropics, the Guinean forests of Western Africa and the Andes Mountains will come under increasing stress as the planet warms, the study finds.
