Warming causes cooling, and drought causes mudslides.
Drought can cause mudslides. When there is plenty of water in the winter and spring, lots of ground cover plants grow and thrive. These plants become part of a hillside. They can last for so many months without water. Then, during the next year’s rainy season, rain mostly runs down the hillsides with the surface intact, protected by the plants. If there wasn’t enough water to support surface plants, the rain after months of dry dust will wash down the side of the dusty mountain and cause the soil to slip with no support.
This is why when we joke that California has two seasons, fire and mudslides, it’s partly true. Fire removes all that protective small bushy growth from a hillside as well.
OK, so drought can cause mudslides. But the explanation that drought leaves glaciers exposed and that makes them melt faster is a bunch of BS. Shasta is always covered with snow. I have seen it in dry years and wet years. It looks the same. But they are willing to say anything to sensationalize any coincidence.
