A longer-term fix could still be years away and cost hundreds of millions of dollars.

A combination of cold air and geography traps wood smoke pollution in Fairbanks. Drier firewood and more efficient stoves are helping.

The measure would open up new opportunities for oil and gas development in the 23-million-acre NPR-A, which is home to an estimated 8.7 billion barrels of recoverable oil.

Although Cook Inlet belugas are known to be susceptible to a variety of bacterial pathogens (10), F. tularensis has not been previously detected in this population, or in other cetaceans. The pattern of pathology represents the pulmonary form of tularemia, and the route of exposure was likely inhalation of contaminated water. F. tularensis is primarily a disease associated with freshwater, but the brackish nature of Cook Inlet and nearshore residence of belugas expose them to potentially contaminated freshwater runoff as well as to other reservoirs typically associated with freshwater (e.g., aquatic rodents, mosquito larvae) (1,2). The cause of the infections in a previously unreported host is unknown; however, host factors such as immunosuppression or environmental changes, such as increased runoff, could be considered.

In 1973, Elden Johnson was a young engineer working on one of the most ambitious and uncertain projects in the world — an 800-mile steel pipeline that carried warm oil over frozen ground. Decades later, Johnson looked back at what he called “the greatest story ever told of man’s interaction with permafrost.”

The spring hunt of any waterfowl except scoters will be closed beginning May 30 at 12:01 a.m. through midnight on June 29. Scoter harvest will be closed between June 4 and July 4.

More than 50 years ago, Elden Johnson helped guide construction of the trans-Alaska pipeline, which snakes above and below ground for 800 miles.

After years of assessments, a major step forward in riverbank stabilization for the Kuskokwim Delta coastal community has been derailed by wide-ranging cuts to the U.S. Environmental Protection Agency.

According to the reserve, in the last decade, the number of white goose in Chukotka has increased. Every spring, about 700 thousand of these birds fly to the island. Previously, this species was endangered and was listed in the Red Book, and now it is a common hunting species. - При перепечатке информации с сайта prochukotku.ru ссылка на первоисточник обязательна.

The paucity of common resident avian species, especially songbirds, was one more peculiar element of an unusually strange Anchorage winter. And, arguably, early spring. Local birders, biologists and watchers all noticed something was off.

Sitka had an early bloom that led to high shellfish toxins in April, and there is currently a paralytic shellfish toxin advisory across Southeast for recreational and subsistence harvest.

Warming temperatures and declining ice cover at Izembek Lagoon are leading thousands of Pacific black brant to overwinter in the Bering Sea instead of flying to southern wintering grounds.

A staple fish that fills freezers in Northwest Arctic could be expanding its habitat

State fire crews began a 35-acre prescribed burn on Anchorage’s Hillside May 12 between Hilltop Ski Area and the Prospect Heights Trailhead, expecting visible smoke and temporary trail closures.

Better knowledge and mapping of existing infrastructure is leading to a new estimate of future thaw costs under varying climate scenarios.

The Knik Tribe's monitoring program for paralytic shellfish poisoning was paused in April as the federal government investigates its legitimacy for funding.

According to an internal budget document, the Trump administration is seeking to end nearly all of NOAA's climate research.

A young wolverine found in a shed in downtown Turku in January was still exceptional. “Wolverines occasionally wander around southwestern Finland. However, the population is concentrated in the east, where conditions are more peaceful,” said Pinja-Emilia Lämsä, a doctoral researcher at Aalto University.
