New study says species moving north faster than previously thought

From Headwater News:
A new study found that more than 2,000 species had begun moving north to escape a warming climate in their traditional habitat at a much faster rate than previously predicted, including the American pika, a small rabbitlike species found in and around Yellowstone National Park, that was never found at elevations higher than 7,800 feet in 1900, but were found at 9,500 feet in 2004.
