While biologists worry primarily about global warming’s effects on life in the Arctic, a seemingly paradoxical result of climate change may be sneaking up on metabolically sensitive creatures in the tropics.

Temperatures in the Arctic have climbed upward faster than in low latitudes. Yet a quirk of physiology could mean that slight upticks in the tropics are delivering a disproportionate jolt to some residents, says Michael Dillon of the University of Wyoming in Laramie.
