Fires in the Arctic are spreading to areas which were formerly fire-resistant. The tundra — north of the Arctic Circle — is drying up and vegetation there like moss, grass, dwarfs shrubs, etc is starting to catch fire.
The fires and record temperatures have the potential of turning the carbon sink into a carbon source and increasing global warming.
