It wouldn’t be spring in the climate change era without a massive heat wave in the Arctic.

Freakishly warm air has billowed up from Siberia over the Arctic Ocean and parts of Greenland, and the heat will only intensify in the coming days. The warmth is helping to spread widespread wildfires and to kickstart ice melt season early, both ominous signs of what summer could hold.

The Arctic has been on one recently. Russia had its hottest winter ever recorded, driven largely by Siberian heat. That heat hasn’t let up as the calendar turns to spring. In fact, it’s intensified and spread across the Arctic. Last month was the hottest April on record for the globe, driven by high Arctic temperatures that averaged an astounding 17 degrees Fahrenheit (9.4 degrees Celsius) above normal, according to NASA data.

Now, a May heat wave has pushed things into overdrive. Martin Stendel, a climate scientist at the Danish Meteorological Institute, told the Washington Post that the mid-May warmth is “quite extraordinary...there is no similar event so early in the season.”

The Arctic is the fastest-warming region on the planet, and these types of heat waves have become a seasonal occurrence. But that shouldn’t make them any less shocking or alarming, particularly since the changes happening there could actually cause the rest of the glove to warm up even more quickly. Melting sea ice exposes darker ocean waters that can absorb more heat, while fires cough up more carbon dioxide into the atmosphere, trapping yet more heat. The zombie fires are even more worrisome, since peat is extremely rich in carbon. The stubborn heat looks to be locked in until at least next week, so we’ll get to see all these horrible feedbacks on display through at least then.
