Climate change could eventually claim a sixth of the world’s species

Up to one-sixth of the species on Earth could disappear if climate change remains on its current course, according to a new analysis of more than 100 smaller studies.
“All the studies are in pretty good agreement: The more warming we have, the more species we’ll lose,” says Dov Sax, a conservation biologist at Brown University who was not involved in the work. “This is really important to know, from a policy viewpoint.”
Industrial emissions of carbon dioxide and other planet-warming greenhouse gases have boosted the global average temperature about 0.8°C (1.44°F) since the beginning of the Industrial Revolution. But studies have disagreed about what impact the rise is having on the world’s species, says Mark Urban, an ecologist at the University of Connecticut, Storrs. Some have estimated that as many as 54% of species could eventually become extinct as a result of climate change, but others have suggested no significant impact.
Such disparate results might stem from the limited nature of some in
