Permafrost thaw and 'shrubification' have tipped Alaska's North Slope into a wildfire regime not seen for 3,000 years
An analysis of peatland soil samples and satellite images has found that wildfires on Alaska's North Slope are more frequent and severe now than they were at any point over the past 3,000 years.

More shrubs in the mountains?! 😮
Why would this be a problem for the local biodiversity? Shrubs are tall and can form dense canopies, eventually outcompeting many of the smaller alpine flowers.
