Greenland’s Northeastern Ice Sheet Melting
18 Mar 2014
by Eilís Quinn, Eye on the Arctic
A new study suggests that Greenland’s northeast ice stream, located 600km to the interior of its ice sheet is thinning because of warming temperatures. The study used data from several dozen GPS locations along Greenland’s coast.
Greenland’s previously stable northeastern ice sheet is starting to melt, according to a new study published in the journal Nature Climate Change.
While Greenland’s melting ice sheet has contributed to an increase in the world’s sea levels over the last 20 years, the recent study suggests that Greenland’s northeast ice stream, located 600km to the interior of the ice sheet is also thinning because of warming temperatures.
Greenland is believed to contribute 0.5 mm per year to the 3.2mm annual rise of the world’s sea levels.

The study used data from several dozen GPS locations along Greenland’s coast.
“The Greenland ice sheet has contributed more than any other ice mass to sea level rise over the last two decades and has the potential, if it were completely melted to raise global sea level by more than seven metres (22.75 feet),” Jonathan Bamber, a professor at Britain’s University of Bristol and one of the study’s co-authors, told Agence France-Presse (AFP) this week.
“About half of the increased contribution of the ice sheet is due to the speedup of glaciers in the south and northwest. Until recently, northeast Greenland has been relatively stable. This new study shows that it is no longer the case.”

Nails for the coffins of climate change denialists from northern Ontario, 300~400 miles NE of Thunder Bay: “The warming trend goes back at least 30 years, and is exemplified by the increase in annual crop heat units (CHU) at Earlton from 1800 to 2300 CHU. This has had a major positive impact on crop production. For example, soybeans, corn grain and silage corn are now reliably grown in the Temiskaming region, while canola has supplemented the traditional barley, oat and wheat crops in the Cochrane-Kapuskasing area. Crop Yields in the Temiskaming District: Corn = 130 – 145 bu/ac, Soybeans = 50 – 60 bu/ac”

Climate change is having a global impact on agriculture, especially in Northeastern Ontario. What could this mean for the future of this region?
