Bees are affected by rising global temperatures, which can increase risks to their survival and pollination roles. A recent study indicates that bees modify their wingbeats to avoid overheating, which impacts their nectar gathering and mating activities. While many bees are traditionally heat-tolerant, climate change and various other stressors like habitat loss, pesticides, diseases, and food scarcity threaten their health and functionality. These combined factors contribute significantly to the global decline of both managed and wild bee populations, posing risks to food systems reliant on their pollination.
As global temperatures rise under climate change, scientists are trying to better understand the effects on managed and wild bees as they pollinate crops, gather nectar, make honey and reproduce.
Scientists also say that bees, like people, may cope by retreating to a cooler environment such as the shade or their nest.
Heat is just one challenge for critical pollinator. Generally, most bees are heat-tolerant, but as the climate warms, their ability to fend off disease and gather food might become harder.
Habitat loss, increased use of pesticides, diseases and lack of forage for both managed and wild bees are all listed as potential contributors to the global decline of bees.
