Bees are vital to producing the fruit, vegetables, nuts and other foods humans rely on. And while they’re generally heat-tolerant, scientists say the warming climate is putting bees at risk by reducing their ability to fend off disease and find food.

Scientists have identified that rising global temperatures are putting bees at risk by causing them to become dehydrated before reaching their heat tolerance limits. This dehydration leads bees to spend more time searching for shade or water, reducing their time spent pollinating crops vital to human food supplies. 

Additionally, the decline in bee diversity, particularly in urban environments, is highlighted as a concern. Researchers suggest that planting a greater variety of flowers that bloom at different times could help support bee populations. However, limited data and reduced funding for bee research may delay further understanding of climate change's impact on pollinators.

Scientists say warming climate putting bees at risk

Bees are vital to producing the fruits, vegetables, nuts and other foods humans rely on. And while they're generally heat tolerant, scientists say the warming climate is putting bees at risk. One of the most interesting things we found is that the vast majority of the species that we are looking at, as their body temperature heats up, which happens as the environment warms up, they become dehydrated. And that was sort of unexpected. And then when we looked at sort of their limits, like how much heating can they tolerate, how much dehydration can they tolerate, what we found is as they got hotter, as their body temperatures got hotter, they became close to their dehydration limits, way before they reached their overheating limits. And when the bees' environment gets stressful, they spend their time searching for shade or water instead of pollinating. Another concern is the lack of diversity among the bees we do have. The bee diversity does decline when it becomes more urban, when you have more pavement, but if you plant more flowers, it erases that decline. So it could be as simple as planting more flowers. Planting more flowers that bloom at different times of year, that provide nectar and pollen resources for the bees at different times of year. That could be the biggest solution. Data is limited on how much climate change is contributing to pollinator decline. U.S. government cuts to bee research programs could mean a long wait for answers.
