WASHINGTON (AP) — Animals across the world are fleeing global warming by heading north much faster than they were less than a decade ago, a new study says.
About 2,000 species examined are moving away from the equator at an average rate of more than 15 feet per day, about a mile per year, according to new research published Thursday in the journal Science which analyzed previous studies. Species are also moving up mountains to escape the heat, but more slowly, averaging about 4 feet a year.
The species — mostly from the Northern Hemisphere and including plants — moved in fits and starts, but over several decades it averages to about 8 inches an hour away from the equator.
"The speed is an important issue," said study main author Chris Thomas of the University of York. "It is faster than we thought."
Included in the analysis was a 2003 study that found species moving north at a rate of just more than a third of a mile per year and up at a rate of 2 feet a year. Camille Parmesan of the University of Texas, who conducted that study, said the new research makes sense because her data ended around the late 1990s and the 2000s were far hotter.
