The Goldilocks Dilemma: Why Climate Change Puts Bumble Bees at Risk

Climate change is pushing many animals to the brink, and surprisingly, winter conditions might be a key factor. Take bumble bees, for instance. These crucial pollinators are struggling due to climate change, but scientists are only beginning to understand how winters affect them. It turns out, bumble bee queens facing the cold need to pick just the right spot in the soil to survive. Too shallow, and they might freeze; too deep, and they waste precious energy. Scientists used this "Goldilocks" effect to create computer models showing how warming temperatures could make it even tougher for these queens to find their perfect spot. The models suggest more temperature swings will mean higher risks. To really know how winter conditions impact dormant creatures, we need more studies on how different animals handle temperature changes while they're hibernating.
