Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to ...

Just as explorers once searched the vast reaches of Africa’s Nile River for clues to its behavior and ultimate source, modern-day scientists are searching Antarctica for its hidden lakes and waterways ...

A new large-scale study of crevasses on the Greenland Ice Sheet shows that those cracks are widening faster as the climate warms, which is likely to speed ice loss and global sea level rise. Crevasses ...

Surface meltwater that drains to the bed of the Greenland Ice Sheet each summer causes changes in ice flow that cannot be fully explained by prevailing theories. Surface meltwater that drains to the ...

Canberra City ACT 2601, Australia. Global warming alarmists have suggested that the ice sheets of Greenland and Antarctica may collapse, causing disastrous sea level rise. This idea is based on the ...

A growing network of meltwater lakes at the edge of the Greenland ice sheet is accelerating the flow of major glaciers, ...

Hotter summer temperatures in Greenland can speed up the seaward flow of the islands massive ice-sheet in just weeks, new research shows. Previously, scientists believed that temperature changes at ...
