A heatwave pulsating through the Arctic helped push Alaska to its warmest month ever recorded in July, with the state’s vast coastline left completely barren of sea ice.

Alaska’s average temperature in July was a record 58.1F (14.5C), nearly 1F above the previous monthly high set in July 2004, according to the National Oceanic and Atmospheric Administration (NOAA). Cities and towns across the vast US state, such as Anchorage, Utqiaġvik (formerly known as Barrow) and Kodiak all had their warmest month in 125 years of record-keeping.

This heat, 5.4F warmer than the long-term average for July, helped spur wildfires that shrouded much of Alaska in a pall of smoke and has now resulted in a remarkable melting away of shoreline ice.

There is now no sea ice within 150 miles of Alaskan shores, according to an analysis by the National Weather Service. The pace of ice loss is “unprecedented” in 40 years of satellite records, scientists said, with the Bering Sea, which separates Alaska from Russia, left completely ice-free.

“It looks like the worst case scenario put forward by the IPCC [International Panel on Climate Change] could be an underestimate because we are seeing ice melting now that we expected 30 to 40 years from now. It’s alarming because it’s very fast-paced and the consequences are hard to predict.”
