Yale Study Links Climate Change to the Decline of Bumblebee Species

New Yale Study Tracks the Impact of Climate Change on Bumblebees

A newly published study from Yale University links climate change to the decline of bumblebee species in North America and Europe.

The study, published in the journal Science, found that bumblebee ranges are shrinking in the south and the insects are not moving north. In addition, some species are moving to higher elevations on both continents.

The study looked at data covering 67 bumblebee species over the course of 110 years, using specimens from institutional collections such as the Yale Peabody Museum of Natural History. “We’re one of the main contributors and provided large amounts of electronic data,” said co-author Lawrence Gall, a Peabody Museum entomologist.

The study found that bumblebee range losses occurred independently of changing land uses or pesticide applications. The data suggested a clear connection to changing climate, the researchers said. “This also highlights the important role that specimens preserved in museums play in current scientific inquiry,” Gall noted.

Lead author Jeremy Kerr of the University of Ottawa said range losses for bumblebees in southern Europe and North America total about 300 km. “The scale and pace of these losses are unprecedented,” Kerr said. “We need new strategies to help these species cope with the effects of human-caused climate change, perhaps assisting them to shift into northern areas.”

    This is just the latest buzz to push panic buttons about the anthropogenic global warming hoax.

    • “We need new strategies to help these species cope with the effects of human-caused climate change, perhaps assisting them to shift into northern areas.”

      Yeah, way to put the emphasis on “human-caused”… Even though the reasons for the climate change are absolutely irrelevant to the study. This is just more “research” that is intentionally linked to doomsday in order to get more grant money. I’ve grown so g’damn sick of the modern research system.

    Climate is the major modifying catalyst of animal evolution. If bumble bee is extinct, another hundred modified varieties may emerge in nature. Extinction of animals and plants are a constant phenomena. Since we cannot control the nature, we have to live with it continuously. Can we truthfully record all the extinct living beings so far in this world? Thank You.

    What ????
    We haven’t polluted some of the air ,water or soils ?
    Ya might wanna get out more and “see” what Humans are doing to Nature …
