摘要：
We tracked the annual extent of rivers on the Greenland ice sheet, revealing that the ice sheet's runoff area expanded by 29% between 1985 and 2020. Strong melting and refreezing has transformed the upper snow and firn layers into thick ice, enabling runoff from higher elevations even during cooler summers.
