During the winter, temperatures at the North Pole spiked above freezing multiple times—an anomaly that used to be rare but is becoming terrifyingly common. In February, the Cape Morris Jesup station in northern Greenland recorded 61°F (6°C) above the seasonal average. For context, that is like having a spring thaw in the middle of the polar night. 2018 was the year scientists started to worry about a region we thought was invincible: the Last Ice Area north of Greenland. This thick, ancient ice (over 5 years old) was supposed to be the refuge for polar species when the rest of the summer ice melted.
As 2018 draws to a close, it is impossible to ignore the headlines coming from the northernmost part of our planet. For scientists, the Arctic is the canary in the coal mine. For geopolitical strategists, it is the next frontier. For the rest of us, 2018 was the year the Arctic officially stopped behaving as it always had.

The numbers are stark: The minimum sea ice extent in September 2018 was tied for the 6th lowest ever. The 12 lowest years on record? All have occurred in the last 12 years.

The Arctic in 2018 wasn't just melting. It was screaming. And while the world was distracted by other news, the thermostat at the top of the world kept climbing.
Here is a look back at the defining moments of the Arctic in 2018. If you remember one statistic from 2018, make it this: The Arctic experienced its second-warmest year on record (second only to 2016). During the winter, temperatures at the North Pole
In August 2018, for the first time in recorded history, the sea ice north of Greenland began to break up. Warm winds and a warm ocean current opened large leads (channels of open water) where there should have been solid ice. It was a visual shock—the fortress had a breach. While we didn't get the "mass starvation" event of 2019, 2018 provided the brutal math of a warming Arctic.
