Researchers have observed extremely high rates of melting at the bottom of the Greenland Ice Sheet, caused by huge quantities of meltwater falling from the surface to the base. As the meltwater falls, energy is converted ...

Underneath Antarctica's vast ice sheets there's a network of rivers and lakes. This is possible because of the insulating blanket of ice above, the flow of heat from within the Earth, and the small amount of heat generated ...
