Libraries at two Anchorage elementary schools — Klatt and Spring Hill — were closed after the maintenance department identified ceiling damage. The district also decided “out of an abundance of caution” to proactively close the libraries of Bear Valley Elementary, Fire Lake Elementary, and Ravenwood Elementary, which share the same building design with Klatt and Spring Hill.

In addition to blizzard conditions, Kotzebue residents have been experiencing power outages, water service interruptions and travel complications because of the storms.

Engineers caution that residents wanting to clear their own roofs face greater risk of hurting themselves or damaging roofs than from a collapse.

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.

East Finnmark region was 4 to 5 degrees warmer than normal in January.

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.

Ship captains are battling with major volumes of sea-ice across the Russian far north. Temperature data show that the Arctic has almost never before been this hot.

Rain began to fall on the already snow-covered Yamal Peninsula, an Arctic region of northwest Siberia, in November 2013. Rain fell for the next 24 hours.  As rain saturated the snow, the temperature dropped below freezing, turning the precipitation into a thick, icy crust. 

National Weather Service says Alaska has been lucky to have three La Niña years. Due to climate change we could see a shift into warmer La and El Nino's.

The Yukon, the N.W.T. and western Nunavut are experiencing above-average temperatures. According to Environment and Climate Change Canada, it's going to stay that way for the month of January.

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.

Warming soils beneath Utqiagvik are triggering erosion that threatens homes, infrastructure and cultural resources. The North Slope has seen some of the fastest changes in coastal erosion in the nation.

Three temperature records this week were broken in Chukotka. Forecasters recorded abnormally high temperatures for this time of year in Pevek and Omolon.

Alaska’s longest and most popular hunting season ended early this year. The Delta Junction bison hunt usually extends from October to March, but the state limited this year’s season to just two weeks, and only 50 animals were taken, because last winter’s heavy snow and ice buildup wiped out nearly a third of the Delta bison herd.

Garbage and wood were removed by the municipal services of the village of Rytkuchi of the Pevek urban district from the coastline and tundra near the settlement. This was the final stage of a large-scale clean-up, which began in the summer after a strong storm.

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.

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.

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.

When hurricanes cause both extreme high tides and heavy rains, devastating floods ensue. Such storms will get much more frequent by the end of the century, according to a new study.
