A third of common land animals could see dramatic losses this century because of climate change, scientists predict.
More than half of plants could be hit the same way as habitats become unsuitable for numerous species. The collapse of ecosystems would have economic impacts on agriculture, air quality, clean water access and tourism.
Global temperatures are set to rise 4C above pre-industrial levels by 2100 if nothing is done to stem greenhouse gas emissions.
This could have a hugely destructive effect on thousands of common as well as endangered species around the world, according to the researchers.
An estimated 57% of plants and 34% of animals were likely to lose half or more of their habitat range. The damage would be greatly reduced, however, if emissions were scaled down in time.
