As Greenland’s ice loss triples over the course of a decade, researchers are growing concerned over the effects of global warming.
Scientists have proclaimed that the last edge of the Greenland ice sheet has now become unstable. On Sunday, researchers announced that the melting of this ice sheet will add billions of tonnes of melt water to the rising sea and cause an imbalance.
The study, which was published in the journal Nature Climate Change, states that from 2003 till now there has been a dramatic temperature increase. This has resulted in the melting of Greenland’s ice sheet.
What once use to be a long and calm river of ice that flowed to the coast of northeastern Greenland is now a raging waterfall. Researchers stated that prior to the temperature increase, the river slowly cycled ice to the sea as there use to be a build-up of ice debris that constrained the river. However, the heat has now removed that blockage and has accelerated the flow of ice.
Known as Zachariae, the ice river covers 16 percent of Greenland’s ice sheet. With this accelerated increase in ice flow to the sea, researchers are now becoming even more concerned with global warming. Leader of the study and Earth sciences professor at Ohio State University Michael Bevis stated:
“Northeast Greenland is very cold. It used to be considered the last stable part of the Greenland ice sheet. This study shows that ice loss in the northeast is now accelerating. So, now it seems that all the margins of the Greenland ice sheet are unstable.”
