The strikes, detected by the NWS station in Fairbanks, Alaska, were produced by towering storm clouds. They were detected on Saturday, and while not unique, come as the region is experiencing record-low sea ice levels, high temperatures and widespread fires on areas of tundra.The strikes, detected by the NWS station in Fairbanks, Alaska, were produced by towering storm clouds.

An extreme ice-melt in Greenland is estimated to have produced a run off of 197bn tons of ice-sheet water into the Atlantic, enough to raise sea levels by 0.5mm, or 0.02in, in a one-month time frame. On a single day, 1 August, Greenland lost 12.5bn tons of surface ice to the sea.An extreme ice-melt in Greenland is estimated to have produced a run off of 197bn tons of ice-sheet water into the Atlantic, enough to raise sea levels by 0.5mm, or 0.02in, in a one-month time frame.

“I wouldn’t say it’s never happened before, but it’s certainly unusual, and it piqued our attention,” Metzger said.“I wouldn’t say it’s never happened before, but it’s certainly unusual, and it piqued our attention,” Metzger said.
The strikes are the latest sign that Arctic warming is accelerating beyond predictions due to human-caused global climate change. In July, Alaska had its hottest month on record with temperatures breaching 90F in Anchorage, exceeding those in Miami.The strikes are the latest sign that Arctic warming is accelerating beyond predictions due to human-caused global climate change.

There is no longer any sea ice present in Alaskan waters, with Bering Sea ice beginning its annual melt in February while the extent of Arctic sea-ice is at its lowest in at least 1,500 years, according to research.
