Study: Climate Change Could Kill Off Bees

This article discusses the impact that global warming could have on bees. Climate change poses all sorts of potential challenges for Earth and those that call it home. But it could be especially troubling for bees.

A new study from Northwestern University and the Chicago Botanic Garden found that global warming could lead to extinction for bees in the southwestern U.S. and other naturally warm climates.

The two-year experiment involved altering the temperature of bees’ nests to simulate a warmer, future climate. The result: 35 percent of bees died in the first year, and 70 percent died in the second year. This was compared to a 1-2 percent mortality rate for bees in a control group, where the temperature was left unchanged.

Results from the study were published Thursday in the British Ecological Society’s journal, Functional Ecology.
