New Study Reveals Fastest Antarctic Glacier Retreat in Modern History

A glacier on the Eastern Antarctic Peninsula has experienced the fastest recorded ice loss in modern history, according to a landmark study co-authored by Swansea University.

The research, published in Nature Geoscience, reveals that Hektoria Glacier lost nearly half its length—eight kilometres of ice—in just two months during 2023; a pace similar to the dramatic retreats seen at the end of the last ice age.

"Hektoria and Green, once glaciated, are now reduced to drifting ice rubble." - Naomi Ochwat, lead author of the study

Led by the University of Colorado Boulder (CU Boulder), an international team—including Swansea glaciologist, Professor Adrian Luckman—found that Hektoria’s retreat was boosted by the shape of the land beneath it.

Author's summary: Fastest Antarctic glacier retreat recorded in modern history.
