“Behold the humble bumblebee.

Hot temperatures linked to climate change, especially extremes like heat waves, are contributing to the decline of these fuzzy and portly creatures, according to a study published Thursday in the journal Science.

Researchers found that bumblebee populations had recently declined by 46 percent in North America and by 17 percent across Europe when compared to a base period of 1901 to 1974. The biggest declines were in areas where temperatures spiked well beyond the historical range, which raises concerns that climate change could increase the risk of extinction for bees, which are already threatened by pesticide use and habitat loss.

“The scale of this decline is really worrying,” said Peter Soroye, a doctoral student in biology at the University of Ottawa and lead author of the study. “This group of organisms is such a critical pollinator in wild landscapes and agricultural regions.”

The common eastern bumblebee, or Bombus impatiens, shown below, is an important pollinator in eastern North America. It’s also the species you’re most likely to encounter in your garden.”
