    Xiao’s study helps fill in the gaps. By analyzing climate and satellite data, Xiao found that a weather anomaly tied to climate change may explain the deadly surge.

    The details are complex, but the new paper — as well as a much lengthier, unpublished study that’s currently under peer review — suggests that climate change is weakening winds, known as the westerlies, that bring dry air into Japan and prevent moist air from the Pacific from flooding in. That’s making northern Japan cloudier.

    With more clouds, less light reaches the forest. And this is key: Without light, forests fail to produce young shoots, nuts, and other foods that bears rely on, the study argues. That leaves bears hungry and likely to venture into human settlements in search of sustenance. Last year, Akita, the epicenter of bear attacks, “endured one of its darkest springs in recent memory,” the authors write, and beech trees in northern Japan produced almost no nuts.

    TLDR: Climate change is reducing the amount of available food for the bears.
