Warming affects tropical species too

Global warming is likely to imperil tropical species much more than fauna in the Arctic regions, even with a slight rise in temperature. "Many tropical species can only tolerate a narrow range of temperatures, as the climate they experience is pretty constant throughout the year,' said Curtis Deutsch of the University of California and co-author of a new study. "Our calculations show that they will be harmed by rising temperatures more than would species in cold climates. Unfortunately, the tropics also hold the large majority of species on the planet,' he said.
