(Extensive wildfires burn though Siberian Khakassia on April 12 of 2015. In the image, we can see down through a break in the cloud deck to view smoke plumes from scores of wildfires raging throughout the region. For reference, bottom edge of frame is 120 miles and the largest burn scars range from 3-5 miles across. As Siberian permafrost burn season progresses, we can expect fires that belch smoke plumes across the Northern Hemisphere emitting from burn scars as large as 30 miles or more across.
