Community-based archaeology in Alaska helps reinforce Indigenous cultural resilience as the Arctic warms four times faster than the global average, amid U.S. executive actions prioritizing fossil‑fuel extraction.

New research highlights potential climate feedback risks as Arctic glaciers melt, with scientists Gabrielle, Leonard, and Silje studying methane emissions, glacial hydrology, and glacier biogeochemistry.

Greenland's icecap shed 139 Gt last year, raising sea level 0.4 mm, but the rate is similar to that of the early 20th century and would take about 27,000 years to disappear at current speeds.

Satellite imagery from summer 2026 shows a new island on Nordaustlandet’s southeast coast after the Austfonna glacier retreated, underscoring rapid Arctic ice loss and its effect on Svalbard’s geography.

Research shows that recent Arctic earthquakes have triggered rockslides and glacier collapses, with warming conditions intensifying the risk of cascading hazards on both Arctic and Nepal slopes. Long‑term analysis underscores the link between climate change and seismic‑induced geohazards.

The piece explores how thawing permafrost, driven by climate change, could heighten the damage from Arctic earthquakes.

Scientists have recorded the first severely deformed invasive pink salmon in Arctic waters, noting worse deformities in the 2024 year‑class and spotting two adult fish with pronounced abnormalities. This finding signals possible ecological impacts of the species in the Arctic.

Europe launches BlueMissionAA2030, a coordinated ocean action initiative that spans the Atlantic and Arctic, marking a new phase of cross‑regional environmental cooperation.

A new weather station has been installed at Grise Fiord, providing real‑time data on Arctic climate change, part of research by the Northern and Arctic Coastal Research Lab under David Didier.

Researchers find that the fungal community in a high-Arctic semi-desert ecosystem has remained stable over a 20-year period, despite climate projections that predict precipitation could double by 2075. The finding suggests that key soil microbial functions may persist even as Arctic weather patterns shift.

Experiments reveal that microplastics smaller than 5 mm, found in Arctic sea ice and down to the ocean’s deepest layers, interfere with plankton feeding and reduce the sinking of carbon‑rich particles, potentially diminishing the Arctic’s role in global carbon sequestration.

New field recordings show that Arctic rivers are creating new channels much faster than previously believed, indicating that erosion processes in the high‑north are more dynamic than scientists had assumed.

The Trump administration’s new policy would exempt drilling and seismic surveys in Alaska from environmental review, potentially allowing activities that scar tundra, disturb female polar bears, and alter caribou behavior, raising concerns over Arctic ecosystem impacts.

MIT researchers drilled a 2‑by‑3‑foot hole through 3.6 feet of Arctic sea ice, deployed a robot below, and transmitted data through the ice at 1.2 kbps.

A new bridge spanning the 475‑foot Pretty Rocks landslide at Polychrome Pass in Denali National Park has opened after five years of engineering, restoring the park road and improving access for visitors and researchers.

From the 1828 rescue of shipwreck survivors to the 1961 wildfire evacuation and the 9/11 air‑passenger sheltering, Newfoundlanders and Labradorians have repeatedly opened their homes in crisis, demonstrating a longstanding tradition of spontaneous hospitality that continues to shape the region’s identity.

NOAA satellite data indicates that the Arctic sea ice extent for 2006‑2025 has been stable but is now nearing its annual minimum, marking a continuation of the linear decline trend that affects Arctic ecosystems and shipping routes.

Korea’s plan to open an Arctic shipping route is challenged by rapid ice melt in polar regions, raising concerns about navigability and environmental impact.

A new study examines how xanthates decompose under Arctic conditions, assessing key environmental parameters. The research comes amid growing interest in expanding Arctic mining, highlighting concerns about potential ecological impacts.

Australian shorebirds travel from Australia to breed in Arctic and sub‑Arctic wetlands across Asia and Alaska, underscoring the global connectivity of these habitats.

A newly discovered Arctic cloud factory can boost cloud particles 50-fold, potentially reshaping climate models and Arctic warming projections, underscoring the role of small‑scale cloud processes in regional climate change.

An Israeli explorer completed a grueling crossing of Spitsbergen, braving blizzards, deep snow and polar bear habitat to test his place in the Arctic.

Chinese and Russian researchers performed their first joint on‑site observation of Arctic sea ice, providing data that could help track climate change and support safer shipping routes.
