AbstractArctic tundra has experienced rapid warming, outpacing global averages, leading to significant greening whose primary drivers include widespread shrubification. Here we confirm that a fire–greening positive feedback loop is evident across the Alaskan tundra, and evidence suggests that this feedback loop is dominated by the fire–shrub interactions.

The fire ecologist didn’t know much about remote sensing when he and some colleagues started noticing burned areas on the Arctic Slope that they knew were not listed in the Alaska Large Fire Database, which includes fires dating to 1939. If the fire record was missing the tundra fires they stumbled across, had it missed others in the past, too? And did the increasing amount of fires in the record in recent years really indicate a trend, or just improved detection methods?
