Atmospheric rivers, those long, powerful streams of moisture in the sky, are becoming more frequent in the Arctic, and they’re helping to drive dramatic shrinking of the Arctic’s sea ice cover.

Six weeks after a series of snowstorms dumped more than three feet of snow, bus stops along a handful of state-maintained roads remain buried, forcing transit users to navigate deep, slippery drifts and towers of snow.

A recent Interior Department grant aims to help residents in Newtok move to higher ground, but it’s just a sliver of what’s needed.

Climatologist Rick Thoman says climate change is driving this more extreme winter snowfall. As the oceans warm, more moisture evaporates into the air. Then, when the atmospheric conditions are right for a storm, that increased evaporation results in “heavier and heavier precipitation,” Thoman said. That’s in part why Anchorage saw 41.2 inches of snow last month, capping off its wettest year on record, according to the National Weather Service.

City officials say crews have made progress. But there are challenges. Crews are currently focused on hauling snow from main streets that are near schools, said Kohlhase’s Thursday email. He said he hopes to get every school cleared by the time classes resume on Monday, Jan. 9.

Three weeks after ex-typhoon Merbok hit Western Alaska and breached the Nome-Council Road, Department of Transportation crews and local contractors finished their repairs.

Alpine permafrost is thawing, according to an article by the National Science Foundation. This is bad news because thawing releases carbon dioxide and methane and because it can cause destabilization of the land, as a couple of northbound drivers found out last week when their car was buried in the slide at 23 miles, as reported in a Chilkat Valley News article.

Golovin was hurt worse than other places in the Norton Sound region by the remnants of typhoon Merbok as it swirled up through Bering Sea last weekend. Repairing the damage is going to take time — and the clock is ticking on winter’s arrival.

The powerful remnants of Typhoon Merbok pounded Alaska’s western coast on Sept. 17, 2022, pushing homes off their foundations and tearing apart protective berms as water flooded communities. Storms aren’t unusual here, but Merbok built up over unusually warm water. Its waves reached 50 feet over the Bering Sea, and its storm surge sent water levels into communities at near record highs along with near hurricane-force winds.

There is still thick sea-ice on the Northern Sea Route as the Russian oil carriers sail along the remote Arctic coasts.

The temperature on the delar of Svalbard has risen to twice as fast as the time period known. No can forecast at the Norwegian Meteorological Institute document the greatest warming in the world.

On Thursday, for the first time, the sheen was reported in Krestof Sound, an area where Pacific herring are known to spawn in the spring.

Ten years ago, Mike Gibeau, then the carnivore biologist for Banff National Park, identified a problem: collisions between grizzly bears and trains were increasingly prevalent. Between 2000 and 2010, ten grizzly bears there were struck and killed by trains and several more unconfirmed strikes were reported.

The troublesome shipping on the Northern Sea Route continues into the new year. Almost three weeks after the world's most powerful icebreaker arrived in the Chukchi Sea, none of the four vessels stuck in the area have broken out of the ice.

Permafrost contains microbes, mammoths, and twice as much carbon as Earth’s atmosphere. What happens when it starts to melt?

If that saying about Jan. 1 setting the tone for the year to come has any truth to it, 2022 is going to be a wild ride.

In 2021, the average temperature in Norway was normal, while precipitation was 10 percent below normal. The year is nevertheless marked by great contrasts. The summary of the weather in 2021 was presented at the Meteorological Institute's annual event Climate Status on 5 January. Here you can see video footage of Climate Status (Vimeo)

It has been an Arctic odyssey for the ships and crews that in November got stuck in sea-ice on the remote Northern Sea Route. After a month of icy captivity and subsequent icebreaker rescue, a convoy of nine vessels this week made it to safety in the Kara Sea. On December 7, a Russian nuclear icebreaker completed

Never before at this time of year have so many vessels been rescued out of the ice, says Russia's nuclear icebreaker operator Rosatom. It has been an Arctic odyssey for the ships and crews that in November got stuck in sea-ice on the remote Northern Sea Route.
