Lemurs and giant tortoises among species at risk if global heating hits 3C

Research warns that large proportions of endemic marine and mountain species face extinction

Unique island species including lemurs and the Galapagos giant tortoise could be at high risk of extinction if the planet warms by more than 3C above pre-industrial levels, new research warns.

Analysis of 270 biodiversity hotspots suggests almost half of endemic marine species and 84% of endemic mountain species will face extinction if the planet warms by more than 3C, which if current trends continue could happen in 2100.
