Microbial communities and ecological functions shift with glacier retreat in the Canadian High Arctic

The review explains how peatlands, covering only 3% of the planet yet holding more carbon than all forests, are vital for climate regulation and biodiversity, and details restoration efforts and policy needs highlighted by the author.

The article explains that polar bears rely on Arctic sea ice, which is now at record lows, making the species unable to survive in Antarctica if relocated, underscoring how climate change limits suitable habitat for Arctic wildlife.

Trump’s 2025 executive order to boost Alaska oil and gas faces criticism from archaeologist Dr Charlotta Hillerdal, who argues that archaeology can become a political ally for Indigenous communities by linking heritage and climate resilience amid rapid Arctic warming.

Scientists have linked the melting of permafrost to a large rock avalanche on Norway’s Jan Mayen island, highlighting climate‑driven geologic hazards in the Arctic.

Heavy rains from Aug. 24 to Sept. 5 caused flooding in Pond Inlet, shutting two streets and damaging pedestrian bridges, but municipal crews built culverts to clear the water and avoid a local emergency. The event also washed up seal bones and artifacts, prompting archaeologist interest.

Satellite and aerial imagery reveal North American beavers expanding into Arctic regions, marking a new wildlife disturbance that may alter local ecosystems.

Freshwater released by melting glaciers in East Greenland’s fjords and coastal shelf is now feeding two major Arctic currents, showing that glacier melt is reshaping ocean circulation in the region.

In 2025, parts of Kiruna, a city in Sweden’s Arctic region, were relocated on 224 wheels, including a 672‑ton church, as iron‑mining‑induced ground deformation threatened the area.

A forecast of a super El Niño suggests that Fairbanks and the Interior will experience below‑average snowfall during mid‑winter, according to climate specialist Rick Thoman who cited patterns from past strong El Niño events.

The study documents that rapid climate change is causing plant community shifts and permafrost thaw in sub‑Arctic palsa mires, underscoring how these coupled changes could diminish Arctic biodiversity and carbon sequestration.

Long‑term cloud condensation nuclei data collected at Pallastunturi and a second Finnish sub‑Arctic site enhance understanding of aerosol‑cloud interactions in the high‑north, supporting climate modeling efforts.

New study shows that wildfire, permafrost thaw and wetlands in Canada release extra greenhouse gases that could raise global warming by 20–30% beyond current models, underscoring the need to revise climate budgets and policy targets.

Scientists tracked Arctic char, lake trout, Greenland cod and marine sculpin using acoustic telemetry near Cambridge Bay, Nunavut, to observe their behavior and habitat use, advancing knowledge of fish health and ecosystem dynamics in the region.

Satellite imagery shows a rare Arctic ice tongue that had been absent for years has reappeared, illustrating that while global warming continues to shrink overall sea ice, certain regions can experience temporary recoveries.

The Federal Energy Regulatory Commission and the North American Electric Reliability Corporation reviewed bulk‑power system upgrades that were implemented to enhance reliability and coordination during the winter 2026 Arctic cold period, confirming that these measures improve system resilience to extreme Arctic winter conditions.

The authors analyze an elevated Arctic liquid fog event observed at a European Arctic site, using Raman lidar and radiosonde data to examine its properties and temporal evolution.

Arctic sea ice in August 2026 fell 9.2% below the 1991‑2020 average, marking the 12th lowest August extent in 48 years of satellite data, underscoring the accelerating loss of winter ice.

The study examines coastal polynyas across the Arctic from 2000‑2018 using a coupled ice‑ocean model, highlighting their role as major winter sea‑ice production zones and noting that current climate models underrepresent these features.

Deninu Kųę́ First Nation has pulled support for the Taltson hydro expansion and the Arctic Economic and Security Corridor until the government and Indigenous partners formally acknowledge its historical impacts and agree to share benefits, citing exclusion from decision‑making and potential environmental harm.
