Antarctic glacier collapses at record speed as Hektoria retreats 15 miles in just 15 months

Antarctica's Hektoria Glacier underwent an astonishing collapse between early 2022 and spring 2023, retreating at a pace rarely seen in modern observations. In just 15 months, the glacier lost roughly 25 kilometers (15 miles) in length. During one especially dramatic two month period, the glacier's terminus pulled back by more than 8 kilometers (5 miles), marking the fastest retreat of grounded glacial ice ever recorded in modern history.
