A large number of uncontrolled fires are burning across the Canadian NWT. The prevailing flow brings some of that smoke to darken Greenland ice.

“The amount of acres burned in the Northwest Territories is six times greater than the 25-year average to-date according to data from the Canadian Interagency Forest Fire Center.

Boreal forests like those in the Northwest Territories are burning at rates “unprecedented” in the past 10,000 years according to the authors of a study put out last year. The northern reaches of the globe are warming at twice the rate as areas closer to the equator, and those hotter conditions are contributing to more widespread burns.

The Intergovernmental Panel on Climate Change’s landmark climate report released earlier this year indicates that for every 1.8°F rise in temperatures, wildfire activity is expected to double.

We have a team on Greenland ice right now, and until mid August, tasked with measuring the impact of dark particles on ice melt. We are asking for support to increase our abilities to detect smoke landing on Greenland ice. The support will help us afford expanding our laboratory work.
