European satellites have detailed the abrupt change in conduct of considered one of Greenland's largest glaciers.

Within the 2000s, Jakobshavn Isbrae was the quickest ice stream on the island, touring 17 km a yr.

As he headed for the ocean, his entrance finish additionally retreated and thinned, with a peak of as much as 20 m per yr.

However now the whole lot adjustments. Jakobshavn travels far more slowly and his trunk has even began to thicken and lengthen.

"It is a full reversal of conduct and it was not deliberate," mentioned Dr. Anna Hogg of the College of Leeds and the UK Polar Observing and Modeling Heart (CPOM).

"The query now’s: what’s the subsequent step for Jakobshavn? Is it only a break or is it a dynamic thinning cease that we've seen earlier than? "

The glacier is positioned in southwestern Greenland. It’s well-known for its spectacular manufacturing of icebergs – colossal boulders calve from its terminus and descend alongside its fjord, into Disko Bay, then into the North Atlantic.

Greater than seemingly, it’s Jakobshavn that spawned the iceberg that sank the Titanic.

The scientists' curiosity within the glacier lies in its position as a drainage channel for the Greenland icecap. It’s a necessary channel for the export of ice which may then elevate the ocean stage.
