The highly pathogenic influenza that just claimed its first known polar bear victim continues to circulate in the world’s wild populations.
A decades-long decline in salmon in the Yukon River has reached a crisis this year, forcing harvest closures and prompting emergency shipments of salmon from other regions of Alaska to river residents who are otherwise facing food shortages.
When 200 million metric tons of rock tumbled down a remote Southeast Alaska mountain in October, nobody was around to see it. But thanks to a beefed-up seismic network and a new system that can distinguish landslides from earthquakes, scientists knew it had happened.
Every year since 2015, the Bering Sea has melted out earlier than in every year before 2015. If heat is killing animals, scientists have yet to pin down exactly how it is doing so.
Clams collected in late August had concentrations of saxitoxin considered dangerous for human consumption. The samples were collected in August about 70 miles north of St. Lawrence Island and about 50 miles north of Cape Lisburne, much further north than previously documented.
Smoke from wildfires in Alaska could cause very unhealthy air quality conditions and low visibility over the weekend in Anchorage, the state's largest city, officials said.
A new report identifies climate change as one of the challenges facing transportation in Alaska's most famous national park.
In New England where ticks have decimated moose, the average tick load is 40,000, and some have been found with 90,000.
Following another year of stark climate impacts in the Arctic, scientists warned Tuesday of a new scourge hitting the region: marine trash. With the region warming twice as fast as the rest of the world, sea ice that has long blanketed the Arctic Ocean is disappearing, opening new routes to shipping.
The 2007 fire was probably the first for that area in 6,500 years, according to scientific evidence examined later, Higuera said. But the wait for the next big burn won't be nearly as long, according to the evidence gathered in the study.
A parasite-riddled seal afraid of the water is the first Alaska marine mammal rescued in 2017. The seal will not be returned to the wild if it continues to survive rehabilitation at the Alaska SeaLife Center in Seward.
Climate-induced habitat changes on Alaska's North Slope such as coastal erosion and permafrost thaw have produced more food for migrating brant, a study says.
One of the largest caribou herds in North America has declined by nearly a quarter in the past two years, hitting a population level that justifies new hunting restrictions. The news was delivered last week at the annual meeting of the Western Arctic Caribou Herd Working Group, an advisory organization with representatives of villages dependent
The booming Bristol Bay salmon run has broken the record set just last year, while on the Yukon River, Chinook are too scarce to harvest.
Smoke and soot from central Alaska wildfires have afflicted the subarctic city of Fairbanks with some of the world's worst air pollution in recent days, forcing many residents indoors and prompting one hospital to set up a "clean air shelter."
Object shot down by US Air Force, ordered by Biden, over North slope of Alaska.
The celebrity glacier on the Kenai Peninsula, though relatively small and getting smaller, looms large in the public consciousness.
Sleeper sharks are already known to range as far north as the Chukchi Sea, but reports of possible shark attacks on seal and sea lions have increased — and now come from further into the Arctic.
As sea ice off Alaska continues its long-term vanishing trend, two seal species that depend on ice may be showing the effects in their bodies. Ribbon seals, distinctive for their black-and-white striped patterns on their fur, and spotted seals, known for their speckled coats, became thinner over time.
Canadian researchers learned that local Inuvialuit hunters had spotted beavers in the region in 2008 and 2009. Those sightings are the first documented signs of North American beaver occupancy on the Beaufort coastal plain.
