According to Jenny Turton, a researcher at Germany’s Friedrich-Alexander Universitat Erlangen-Nurnberg, heatwaves in recent years have accelerated the melting.

“Each summer, water drains from the Greenland ice sheet onto the tongue of the glacier, forming rivers and ponds on the surface. Refreezing of the water in winter creates additional pressure on the floating tongue, which can lead to calving events,” Turston said in a statement published by GEUS.
Researchers said the development mirrored that of a neighbouring glacier, the Zachariae, which collapsed into the ocean in 2015, leading to an increase in calving as it was heated from both the ocean and air.
