Large Chunk of Greenland’s Largest Glacier Simply Crashed Into The Sea

A large chunk of ice – bigger than the town of Paris – has damaged off from the Arctic’s largest ice shelf due to hotter temperatures in Greenland, scientists stated Monday.


The 113-square-kilometre (43-square-mile) block broke off the Nioghalvfjerdsfjorden glacier in Northeast Greenland, which the scientists stated had been anticipated given the rising common temperatures.

“We’re observing rising pace on this largest remaining ice shelf,” Jason Field, professor of glaciology on the Geological Survey of Denmark and Greenland (GEUS), instructed AFP.

GEUS additionally revealed satellite tv for pc pictures displaying the parts of the glacier that had damaged off.

Whereas it’s regular for items of ice to interrupt off from a glacier – a course of known as calving – they’re typically not this huge.

In response to GEUS, since 1999, the glacier has misplaced 160 sq. kilometres of ice, an space twice the scale of Manhattan, with the loss charge accelerating prior to now two years.

“If we see extra heat summers like we noticed the final two years, it will likely be contributing extra to the accelerating international sea degree rise,” Field stated.

The melting of Greenland’s ice sheet contributed to a sea degree rise of 1.1 centimetres between 1992 and 2018, in response to a research revealed within the science journal Nature in December.


A more moderen research by the College of Lincoln in England predicted that the melting ice in Greenland might increase sea ranges by 10 to 12 centimetres by 2100.

Common temperatures within the area have risen by about three levels Celsius since 1980 and are anticipated to succeed in file ranges in 2020.

In response to Jenny Turton, a researcher at Germany’s Friedrich-Alexander Universitat Erlangen-Nurnberg, heatwaves lately have accelerated the melting.

“Every summer season, water drains from the Greenland ice sheet onto the tongue of the glacier, forming rivers and ponds on the floor. Refreezing of the water in winter creates further stress on the floating tongue, which might result in calving occasions,” Turston stated in a press release revealed by GEUS.

Researchers stated the event mirrored that of a neighbouring glacier, the Zachariae, which collapsed into the ocean in 2015, resulting in a rise in calving because it was heated from each the ocean and air.
