Scientists alarmed after two wildfires hit Greenland within a week

Scientists and local officials in Greenland are raising alarms after two wildfires were reported within a week in mid-June, an unusually early start to the Arctic fire season.

The first fire burned near Sisimiut, on Greenland’s west coast, on June 14 and was still visible in satellite imagery the following day. A second blaze was reported in Kujalleq on June 17.

The timing stood out to researchers. Vegetation fires at high northern latitudes are more often associated with July and August, not mid-June.

Dr. Mark Parrington of the Copernicus Atmosphere Monitoring Service said the early timing was particularly unusual. Sonja Diaz of the University of Helsinki said the fires were early, but still fit conditions that have to be warm and dry enough for flames to spread.

What happened near Sisimiut

In the Sisimiut area, Qeqqata municipality emergency manager Inunnguaq Eigil Lundblad said the fire appeared to have been started recklessly by a person.

He also pointed to very dry soil, little snow and little rainfall as factors that left the area vulnerable. The combination helped explain why a fire could take hold so early in the season.

Satellite imagery showed the Sisimiut fire persisting across at least two days, underscoring how quickly dry Arctic ground can become a fire risk once ignition occurs.

The Kujalleq blaze

The second wildfire was reported in Kujalleq on June 17. Miki Sikemsen, the municipality’s emergency manager, said the immediate trigger was not yet known.

He said there had been no significant rainfall since May. That left the ground dry enough for fire to spread once conditions turned favorable.

Taken together, the two blazes suggested that the problem was not limited to one location or one incident. Officials were describing broad dryness across parts of southern and western Greenland.

Why scientists are concerned

Pelle Tejsner of the University of Greenland said the dry soil meant more fires could be expected. That concern goes beyond the individual blazes and points to a larger shift in Arctic fire behavior.

Greenland is often associated with ice, but its ice-free tundra can burn. When that happens, fires can release carbon stored in old peaty soils, adding a climate impact on top of the immediate local danger.

Researchers say Arctic warming is making fire-prone conditions more likely, and the Greenland fires fit that wider pattern of earlier and drier fire seasons.

The Guardian reported that Greenland wildfires remain rare but are becoming more common. It cited research showing no detected blazes in ice-free western Greenland from 1995 to 2007, followed by 21 separate events from 2008 to 2020, including major fires in 2017 and 2019.

What comes next

Researchers are watching for additional satellite analysis, fire-service assessments and any standalone municipal statements that could clarify how the fires spread and whether either blaze remained active beyond the reported dates.

The broader question is whether June’s fires were isolated events or another sign that Arctic wildfire seasons are expanding and starting sooner than expected.
