Greenland Ice Sheet Not Covered In Soot

Greenland ice sheet not covered in soot | Behind The Black

“The uncertainty of science: A new study of the Greenland ice sheet has found that the darkening sensed there by satellites is not caused by dust and soot deposited by forest fires and industry but was instead caused by the slow degradation of the sensors on the satellites themselves.

In trying to explain the apparent decline in reflectivity, lead author Chris Polashenski, an adjunct assistant professor at Dartmouth’s Thayer School of Engineering and a research geophysicist at the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory, and his colleagues analyzed dozens of snow-pit samples from the 2012-2014 snowfalls across northern Greenland and compared them with samples from earlier years. The results showed no significant change in the quantity of black carbon deposited for the past 60 years”
