After a number of quieter years, wildfires have returned to western Greenland.
Two fresh fires have introduced renewed consideration to a panorama extra most often related to glaciers and melting ice sheets than flames. But if we visited the area in 2023 to research a sequence of odd huge wildfires that burned a couple of years previous, native citizens informed us they wouldn’t be stunned if the fires got here again.
They remembered how dry the panorama had change into earlier than the fires, which made wildfire more straightforward to begin and tougher to keep an eye on. For other folks residing round Sisimiut on Greenland’s west coast, those newest occasions are subsequently now not fully surprising.
Our analysis suggests wildfires could also be a part of a brand new Arctic truth.

All the way through our 2023 fieldwork we spoke to firefighters, native trade homeowners and land-users, tourism managers and global guests, all of whom had direct enjoy of the sooner fires. A not unusual thread used to be that those fires have been not like the rest they remembered.
A lot of the ones fires, together with one that burned within the tundra for a number of weeks, coincided with an strangely heat, dry spell between 2015 and 2020. Even if wetter summers adopted, bringing a brief lull, this 12 months’s fires recommend the ones stipulations have returned.

The marvel wasn’t restricted to native citizens. This a part of Greenland draws hundreds of cruise send guests and journey vacationers, many mountaineering the multi-day Arctic Circle Path between Kangerlussuaq and Sisimiut. The hikers we spoke to have been surprised to come upon fires: “I’ve obviously heard of wildfires before but, you know, you sort of associate that with Australia or California […] it never crossed my mind that it would ever happen in Greenland.”
That chance has modified how the panorama is controlled. Lots of the fires came about alongside the path, main native government to remind guests about accountable use of campfires, and to distribute a briefing word on wildfires that we produced.
Greenland has all the time had a minimum of some fires, and standard panorama customers have lengthy practised secure hearth control, for instance development fires on bedrock clear of crops and taking care with smoke ovens, passing this knowledge down the generations to at the present time. On the other hand, the exceptionally dry stipulations in the ones years made the panorama itself a lot more flammable.
The burning tundra
Not like the wooded area fires that dominate headlines in different places, Greenland’s wildfires most often burn within the tundra, spreading thru mosses, shrubs and organic-rich soils reminiscent of peat which can be increasingly more being uncovered as permafrost melts.
This makes them specifically tough to struggle. Firefighters in Sisimiut informed us that the fires don’t simply burn around the floor, however can smoulder underground for days or weeks, spreading ignored earlier than flaring up once more. All the way through lengthy dry spells, close by lakes might also change into too shallow to offer sufficient water to position out the fires, making an already difficult job even tougher in Greenland’s far off tundra.

Those fires have far-reaching penalties. Smouldering tundra releases huge quantities of carbon that has been locked away in soils for hundreds of years, including to the greenhouse gases warming the local weather. When soot from the ones fires is deposited at the close by Greenland Ice Sheet it’ll even boost up melting via darkening the outside. The fires additionally produce positive particulate air pollution, which is able to commute lengthy distances and pose severe well being dangers to communities a long way from the flames.

Scientists have warned for years that local weather trade would building up wildfires around the Arctic. In puts reminiscent of Siberia it’s already going down. In that context, the 2015-2020 fires might constitute Greenland following the similar trail. Because the local weather continues to heat, and the stipulations that drove the fires change into extra not unusual, wildfire is more likely to change into an increasingly more acquainted function of a panorama lengthy outlined via ice.
“For sure, we have the fire on our memory”, one particular person we interviewed informed us in 2023, when our fieldwork came about in every week of continuing rain. However even then, the citizens have been transparent: if dry stipulations returned, so would fires.
This summer time, after an strangely heat and dry iciness, this is precisely what came about.
