Climate change drives animals to high ground
18.08.11
Global warming is causing animals and plants to migrate further up mountains and away from the equator in attempts to avoid the higher temperatures associated with climate change, scientists have found in an exhaustive survey of nearly 1,400 species.
The rate of movement is on average up to three times faster than previously expected for species migrating towards the poles and about twice as fast for organisms that are migrating further up the sides of mountains, the scientists said.
A major review of the distribution of animals and plants, published in the journal Science, found wide variations between individual species but taken as a group there appears to be unequivocal evidence that climate change is the cause of the mass movement, said Professor Chris Thomas of the University of York.
"Species of animals and plants have been moving their distributions away from the equator and towards the poles much faster than previously realised. In fact species are moving northward in the northern hemisphere and southward in the southern hemisphere on average at a rate of about 16km or 17km per decade," Professor Thomas said.
