Tropical species also threatened by climate change

WASHINGTON - If you can't stand global warming, get out of the tropics. While the most significant harm from climate change so far has been in the polar regions, tropical plants and animals may face an even greater threat, say scientists who studied conditions in Costa Rica.

"Many lowland tropical species could be in trouble," the team of researchers, led by Robert K. Colwell of the University of Connecticut, warns in Friday's edition of the journal Science.

"The tropics, in the popular view, are already hot, so how could global warming harm tropical species? We hope to put this concern on the conservation agenda," Colwell said.
