One in 10 Species Could Face Extinction: Decline in Species Shows Climate Change Warnings Not Exaggerated, Research Find

ScienceDaily (July 12, 2011) — One in 10 species could face extinction by the year 2100 if current climate change impacts continue. This is the result of University of Exeter research, examining studies on the effects of recent climate change on plant and animal species and comparing this with predictions of future declines. Published in leading [...]
