Global Warming Causing Plants, Animals to Flee Upwards and Reshuffle – International Business Times http://www.ibtimes.com/articles/200556/20110819/global-warming-causing-plants-animals-to-flee-upwards-and-reshuffle-ecosystems-university-of-york-co.htm?cid=2

The study reveals that species have moved toward the poles where the conditions are cooler at almost three times the normal rate and also toward higher altitudes at twice the previous known rate.

A study of more than 1,300 different species of animals and plants by the research team has shown a specific trend of movement. On average, species have shifted to higher elevations at 12.2 meters per decade and, more dramatically, to higher latitudes at 17.6 kilometers per decade.
