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.

 

About the author Jason Box

Dr. Jason Box has been investigating Greenland ice sheet sensitivity to weather and climate as part of 23 expeditions to Greenland since 1994. His time camping on the inland ice exceeds 1 year. Year 2012 brought a deeper level of insight as the scientific perspective shifts to examine the interactions ice with atmospheric and ocean systems, including the role of fire in darkening the cryosphere. As part of his academic enterprise, Box has authored or co-authored 50+ peer-reviewed publications related to Greenland cryosphere-climate interactions. Box instructed climatology courses at The Ohio State University 2003-2012. Box is now a Professor at the Geological Survey of Denmark and Greenland (GEUS). Box was a contributing author to the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change 2007 4th assessment report. Box is also the former Chair of the Cryosphere Focus Group of the American Geophysical Union.
