Bumblebee populations in North America and Europe have plummeted amid rising temperatures and heat extremes, according to new research. A study in Science finds a 46 percent decline in areas inhabited by bees in North America and a 17 percent decline in Europe, a pattern it asserts is linked to increasingly severe heat and other climate extremes. Bumblebees are key pollinators, but their large bodies and preference for cooler climates make them vulnerable to extreme heat. |
