The rising frequency of extremely hot temperatures tied to human-caused global heating is creating “climate chaos” that drives widespread declines of bumblebees, some of the planet’s most important pollinators, according to a new study published in the journal Science.
Researchers at the University of Ottawa in Canada and University College London in the United Kingdom developed a new measurement of temperature based on species’ heat tolerance. “We have created a new way to predict local extinctions that tells us, for each species individually, whether climate change is creating temperatures that exceed what the bumblebees can handle,” explained study co-author Tim Newbold.
