As global temperatures increase, bees experience significant challenges including rising heat, which can elevate their body temperatures. They have shown adaptability by using fewer but more powerful wingbeats to regulate their temperature. However, continued climate change may hinder their ability to resist diseases and find food. Habitat loss, increased pesticides, and insufficient forage are also contributing to the decline of both managed and wild bee populations. This year’s US Beekeeping Survey indicates substantial losses, with beekeepers reporting a 56 percent decline in managed colonies, the worst since tracking began.
Bees, like people, may cope with rising heat by retreating to cooler environments, such as shade or their nests, to avoid overheating, researchers found.
As global temperatures rise, scientists are studying how heat affects both managed and wild bees as they pollinate crops, gather nectar, and reproduce.
The effects of global warming on bees include increased disease susceptibility and challenges in gathering food, alongside threats from habitat loss and pesticide use.
The annual US Beekeeping Survey revealed that beekeepers lost nearly 56 percent of their managed colonies this year, the highest loss since 2010.
