Unusual weather patterns in Sweden’s arctic region seem to be jeopardising the migrating animals’ traditional grazing grounds, as rainfall during the winter has led to thick layers of snowy ice that block access to food.

The birds are smart and attractive, but can also be a hazard for other avian species and the environment.

For the past five years or so, former state Sen. Randall Hardy has watched a few dozen turkey vultures roost in a tree next to his garage. He can tell when the migratory birds return to his central Salina neighborhood each spring as the colors begin to change.

Task Force Iqaluit is making plans to move its water purification operation indoors, after a winter storm knocked down the tent housing its purifying system. Meanwhile, city staff are being redeployed due to the crisis, leading to some cuts to recreation services.

This summer, for the first time on record, rain fell on Greenland’s frozen summit. The Northern Hemisphere experienced warmer-than-usual summer temperatures this year, and even the coldest environments are being impacted.

Employees of the Kronotsky Reserve have published the results of a large-scale summer expedition to collect and classify garbage on the coast of the South Kamchatka Federal Reserve. The main pollutants that threaten the lives of marine and coastal animals are identified.

Researchers are predicting low fish runs in the Norton Sound and Northern Bering Sea region again next year, according to research biologist Jim Murphy.

Lake Superior is warming faster than any of the Great Lakes, with impacts on ice fishing, wildlife and Indigenous ways of life

Researchers from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences (CAS) and their collaborators published a high-accuracy and high-resolution permafrost map over the Northern Hemisphere.

This season’s quotas of snow crab catch were slashed by nearly 90%, a body blow to the small island government on St. Paul, where the crab are processed — and taxed.

Coxiella burnetii, a zoonotic bacterium, has recently been identified in several marine mammal species on the Pacific Coast of North America, but little is known about the epidemiology, transmission, and pathogenesis in these species.

A Bering Strait study, part of a program examining ear infections and hearing loss, links lack of running water to childhood ear diseases.

Experts say a wasting disease epidemic has decimated about 95% of the sunflower sea star population from Alaska’s Aleutian Islands to Mexico’s Baja California peninsula. Without sea stars to keep them in check, sea urchins are causing a troubling decline in kelp forests that provide food and shelter.

The Alaska blackfish is an evolutionary loner that fins through lakes and tundra ponds across much of the state. It exists nowhere else, except just across Bering Strait in Siberia. The fish is different from others in the state because in addition to gathering oxygen through its gills, it can pull oxygen from free air.

The Arctic Encounter Symposium (AES) held its 2023 event, bringing together policymakers, industry leaders, military leaders and other experts to discuss the leading issues in Arctic policy, innovation and development. The event allowed attendees to hear from several Alaska Natives about their experiences in a rapidly changing climate and ecosystem.

The risk of a tsunami hitting Anchorage – Alaska’s largest city, at the head of Cook Inlet – has been the subject of debate for years.

A growing number of Americans are finding it difficult to afford insurance on their homes, a problem only expected to worsen because insurers and lawmakers have underestimated the impact of climate change, a new report says. “If you’re not worried, you’re not paying attention,” said California Sen. Bill Dodd, whose district includes the wine-country counties devastated by the LNU Complex fires in 2020.

The Northern Bering Sea showed signs of ecological recovery in 2023, with improved conditions for zooplankton and fish despite ongoing challenges from climate change and variable sea ice patterns.

"We need to keep all political options open, including a withdrawal from the Arctic Council," says Russia's Arctic Ambassador, Nikolay Korchunov.
