Huge hidden flood bursts through the Greenland ice sheet surface +EMBARGO 0900GMT 30 July 2025+
A sudden flood from a hidden lake beneath Greenland's ice sheet reveals a powerful meltwater process not currently accounted for in climate change models. As global warming intensifies, researchers say the discovery highlights the need to better understand how ice sheets respond to extreme melts.

Ancient river landscapes under Antarctica may may stabilize ice sheet
Landscapes left behind by ancient rivers and buried beneath the Antarctic ice may affect the rate of ice loss, researchers report in Nature Geoscience. The team used radio echo sounding, a technique that measures ice thickness using radar, to study the East Antarctic Ice Sheet between Princess Elizabeth Land and George V Land in Antarctica. Parts of the ice sheet are thought to be particularly susceptible to climate change because the land beneath it contains huge troughs that let warming ocean water reach the ice, causing rapid shrinking.
