Also in the mid-1990s, another group of scientists proposed the now widely accepted mechanism for how lakes can form under glaciers: Heat radiating from Earth's interior is trapped under the thick, insulating ice sheet, and pressure from the weight of all the ice above it lowers the melting point of the ice at the bottom.
