A new study reports that Atlantic salmon exposed to the anti-anxiety drug clobazam during migration became bolder, passing through hydropower dams faster, though this behavior might increase predation risk later.

A new study finds that polar bears in Svalbard are beginning to leave their dens with cubs one week earlier than before 2016, a trend that may be linked to climate change and the resulting loss of sea ice.

A recent report highlights the unprecedented low snowfall during the 2024-2025 winter in Anchorage and Southcentral Alaska, affecting not only the weather but also events like the Iditarod race.

Salmon advocates have raised concerns over declining salmon numbers, blaming an oversupply of hatchery-reared fish that overwhelms natural stocks and disrupts ocean ecosystems.

This article explains how Interior Alaska’s cold, airy snow uniquely bends off railings and loops from power lines, defying gravity due to slow deformation and the sintering process.

Seismic activity at the Sundhnúk crater row has intensified with over 20 earthquakes recorded in the past 24 hours, while a separate swarm in Öxarfjörður is being closely monitored.

Anchorage School District has activated its Emergency Operations Center and released a preparedness plan for a potential eruption of Mount Spurr, located 75 miles west of Anchorage.

An investigation into the death of roughly 100 fish near Alaska’s Kensington gold mine remains inconclusive months later, with both state regulators and Coeur Mining unable to pinpoint the cause despite extensive testing.

Researchers warn that European glaciers are retreating rapidly, exemplified by significant losses in Norwegian glaciers, potentially jeopardizing water supplies, agriculture, and energy. The article highlights the urgency of glacier conservation on World Glacier Day 2025.

The City of Ketchikan is recovering from a landslide that displaced hundreds of residents, prompting swift emergency responses and community cooperation, though no injuries were reported.

A Unesco report warns that unprecedented glacier melt driven by the climate crisis threatens the food and water supply for two billion people worldwide, with major impacts on irrigated agriculture and mountain communities.

Anchorage has upgraded its emergency response to level two due to potential eruption risks from Mount Spurr, located 75 miles west of the city.

A new report by the World Meteorological Organization declares 2024 as the warmest year in 175 years, driven by human-caused CO2 emissions. The unprecedented warmth is raising sea levels faster and endangering millions along coastlines, especially in Arctic regions like Svalbard.

While the U.S. grapples with an egg shortage caused by avian flu, eggs remain plentiful and affordable in Canada. There are reasons for that, including that egg farms there tend to be smaller.

In Maine, Wabanaki tribes, scientists, and conservation groups are banding together to preserve native seeds, particularly those of the culturally significant brown ash, as a defense against the invasive emerald ash borer.

A powerful storm in southwest Iceland caused extensive coastal damage and raised concerns over the adequacy of existing sea defences, prompting calls for a significant increase in funding for future protection.

"The amount we could export would not solve their egg shortage," says the head of the Finnish Poultry Association.

Researchers in southwestern Alaska are investigating why the once-thriving Mulchatna caribou herd has not rebounded, focusing on factors such as disease and nutrition. The study employs real-time monitoring of pregnant caribou and detailed fat measurements to evaluate calf survival and overall herd health.

Researchers in southwestern Alaska are closely monitoring the Mulchatna caribou herd using advanced technology to determine whether disease or nutrition is behind the herd’s failure to recover. The study comes amid efforts to understand a dramatic population decline that has led to a subsistence hunting closure.

Rising Arctic temperatures are causing centuries-old graves on Svalbard to deteriorate, with collapsing coffins exposing skeletal remains to the elements.
