Temperature Extremes Increasing Local Extinction of Bumblebees

A study published in Science indicates that an increasing frequency of unusually hot days is leading to local extinctions of bumblebees. The study of 66 bumblebee species across North America and Europe found that increasing frequency of hotter temperatures reliably predicts species’ local extinction risk. Furthermore, the method developed in this study that permits spatially explicit predictions of climate change–related population extinction-colonization dynamics could also predict and explain wider biodiversity losses.
