Meta-analysis of current global warming impacts suggests a third of all species could be extinct by 2100

A biologist at the University of Connecticut has found evidence that up to a third of all species alive today could go extinct by 2100 if greenhouse gas emissions are not slowed or stopped. In his study published in the journal Science, Mark Urban conducted an analysis of 485 studies carried out over the past 30 years on the ability of species to adapt to climate change.
