Climate change is causing wild bumblebees to disappear from large swaths of their historical range, which could spell disaster for pollinating crops in Europe and North America, new research suggests.
As global temperatures have risen, bumblebees have disappeared from the warmest regions they occupy, but have not spread northward to take advantage of new habitat, the study finds.
"They just aren't colonizing new areas to track rapid, human-caused climate change," study co-author Jeremy Kerr, a biologist at the University of Ottawa, said at a news conference.
