Heavy Rain Can Speed Up Alaska's Sít' Kusá Glacier, Study Finds
Researchers report that intense rainfall can roughly double the speed of Alaska's Sít' Kusá Glacier. The study shows these rainfall-driven surges last longer than scientists had previously recorded. The glacier's movement depends heavily on how efficiently meltwater drains beneath it, since this shapes how water interacts with the ice. The findings point to meaningful shifts in how the glacier behaves under changing conditions. Because climate change is expected to increase rainfall, the researchers suggest such glacier accelerations could become more frequent.
