There are new signs that killer whales, which are swimming farther north and staying for longer periods of the year in Arctic waters, are increasingly preying on Alaska’s bowhead whales. A newly published study found that 2019, an especially warm year in the region, also seems to have been an especially dangerous year for bowheads.

Some Southeast fishermen skipping fall season entirely, other’s say season has been “hit or miss”

As the driest summer in Seattle’s record books ended, trees across the city were sounding silent alarms. It was the latest in a string of Seattle summers in the last decade, including a record-breaking heat dome in 2021, to feature drier conditions and hotter temperatures that have left many trees with premature brown leaves and needles, bald branches and excessive seeding –- all signs of stress.

The recent closure of the Bering Sea snow crab and Bristol Bay red king crab fisheries has some Western Alaska towns taking a hard look at their futures, including St. Paul.

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.

Researchers have detected striking changes in narwhal migration times driven by climate changes in the North. "Our long-term dataset identified that passage boundary crossing dates were associated with changing sea ice dynamics as a result of climate change," the researchers said in their paper p

For the first time ever, the Bering Sea snow crab fishery will not open for the upcoming season. The Bristol Bay red king crab fishery will also be closed for a second year in a row.

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.

Iñupiat communities have been looking for alternatives to traditional ice cellars. Some households switched to using manmade freezers, which can be effective but they affect the taste and the quality of the food, Nelson said. Additionally, power outages, frequent in the villages, can make this storage method unreliable. So the search is on for creative ideas to preserve traditional ice cellars.

A study – now in its eighth year – has found a remarkably diverse diet among the region’s wolf population. Sea otter has become a primary source of food.  

Southeast Alaska’s wolves tend to favor deer and moose at mealtime, but in a pinch they won’t say no to black bear – or even sea otter.

These lakes form because warm temperatures in the Arctic are melting the permafrost.

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.

Smoke from a Siberian wildfire may have transported enough nitrogen to parts of the Arctic Ocean to amplify a phytoplankton bloom.

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.

Sweden's highest mountain Kebnekaise's southern peak has not shrunk further over the last year, scientists say. "I think the explanation is that it was quite a cold summer up here in the Kebnekaise Mountains and at the Tarfala research station so it has not melted away so much" says Nina Kirchner, director at Tarfala research center.

Yukon River chinook salmon runs have been steadily declining, with 2022 the smallest run on record. As the fish disappear, Yukon First Nations fear the cultures and traditions built around the salmon over countless generations will too.

Anchorage’s backyard wilderness is experiencing a surge in users that shows no signs of letting up. Driven in part by social media and location tracking apps, more people are recreating in historically less-used parts of the park than before.

Researchers found pesticide-contaminated plants in nurseries in 15 states
