Antarctica

In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a new study. By combining 25 years of European Space Agency satellite altimeter measurements and a model of the regional climate, the UK Centre for Polar…
Monitoring Antarctica from space has revealed how its ice is being lost to the oceans, providing crucial insight into the continent’s response to a warming climate. Scientists from the University of Leeds, the University of California San Diego and University of Maryland reviewed decades of satellite measurements to reveal how and why Antarctica’s glaciers, ice…
Ice losses from Antarctica have increased global sea levels by 7.6 mm since 1992, with two fifths of this rise (3.0 mm) coming in the last five years alone. The findings are from a major climate assessment known as the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), and are published today in Nature. It is…
Research demonstrating the melting of Antarctica’s biggest glaciers at their base, contributing to a speeding up of global sea level rise, has received worldwide attention. The study, led by scientists from the Centre for Polar Observation and Modelling (CPOM) at the University of Leeds, was published in Nature Geoscience on Monday 2 April 2018. (See…
Antarctica’s great ice sheet is losing ground as it is eroded by warm ocean water circulating beneath its floating edge, a new study has found. Research by the UK Centre for Polar Observation and Modelling (CPOM) at the University of Leeds has produced the first complete map of how the ice sheet’s submarine edge, or…
