Stratospheric clouds over the Arctic may explain the differences seen between the polar warming calculated by climate models and actual recordings, according to researchers from the University of Cambridge and UNSW Sydney.

Ice sheets can retreat up to 600 metres a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured.

Researchers have found that the movement of glaciers in Greenland is more complex than previously thought, with deformation in regions of warmer ice containing small amounts of water accounting for motion that had often been assumed to be caused by sliding where the ice meets the bedrock beneath.

Scientists have used fibre-optic sensing to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet. Their findings will be used to make more accurate models of the future movement of the world’s second-largest ice sheet, as the effects of climate change continue to accelerate.

The filling and draining of meltwater lakes has been found to cause a floating Antarctic ice shelf to flex, potentially threatening its stability.

In early January, a team of Cambridge scientists set out on an expedition to study and map the Larsen C ice shelf in western Antarctica, and – ice conditions permitting – search for the wreckage of Sir Ernest Shackleton’s Endurance. 

A new study finds that changing climate in the polar regions can affect conditions in the rest of the world far quicker than previously thought.

A new study finds that the Greenland Ice Sheet, which covers 1.7 million square kilometres and contains enough ice to raise sea levels worldwide by seven metres, is less stable and more sensitive to climate change than previously thought.

The Scott Polar Research Institute has launched an appeal to save Captain Robert Falcon Scott’s ‘lost’ polar negatives. A last minute stay of execution means it now has until 25 March to save the negatives for the nation.

An urgent appeal to save 113 photographic negatives taken by Captain Scott has been launched today (February 11) by the University of Cambridge’s Polar Museum.
