While the wildfire could possibly be the biggest in the icy country's history, their satellite records go back only as far as the year 2000, and it's "certainly the biggest one" in that respect, said remote-sensing scientist Stef Lhermitte, speaking to New Scientist.
Wildfires in Greenland, which is mostly associated with snow, are not unusual. In fact, the region experienced similar wildfires in both August 2016 and 2015, but "2017 is exceptional in the number of active fire detections," Professor Lhermitte tweeted.
The "sizable wildfire" is burning roughly 90 miles northeast of Greenland's second-largest town, Sisimiut, which has a population of 5,500 people and rests on the island's west coast, according to NASA.
"Most of Greenland is covered by ice, but dwarf willows, shrubs, grasses, mosses, and other vegetation do live in some coastal areas," NASA wrote.
First spotted by a pilot on July 31, the wildfire has continued to spread slowly, and with no rainfall forecast for the foreseeable future, the growing blaze threatens reindeer grazing and prevents hunting in the area.
It's not clear what triggered the blaze, however it appears to be a "peatland fire" and could be a result of the once-frozen ground melting, drying out, and becoming flammable if full of turf, according to Jessica McCarty of Miami University, who spoke to Wildfire Today.
