Scientists present new visual data showing ozone concentrations across the Arctic from 1978 to 2024, highlighting years with unusually high total column ozone indicated by pink lines on the map.

Analyses indicate that the long‑term rate at which winter sea ice in the Arctic is shrinking has slowed in the early 2020s, according to 20‑year trend data.

UK‑based Gino Watkins Fund announces new awards for polar expeditions, backing researchers, teams and explorers to deepen knowledge of the Arctic and Antarctic.

A new study tracing shrub scar evidence and satellite imagery shows that climate change is pushing North American beavers into previously ice‑bound Canadian Arctic areas, where their dam‑building could reshape local landscapes.

Scientists suggest a coordinated experiment of Arctic climate models to map the ocean’s response functions, aiming to refine projections of temperature and sea‑ice dynamics.

The paper reviews how Arctic Ocean circulation is being reshaped by ongoing warming, freshening, and sea‑ice loss, outlining the resulting shifts in heat transport and their implications for regional ecosystems and global climate models.

China has set sail from Dalian with four research vessels—icebreakers Xuelong and Xuelong 2 plus Jidi and Tansuo 3—to conduct multi‑disciplinary studies of sea ice, ocean chemistry, biology, atmospheric dynamics, and geoscience across the Arctic Ocean. The mission, begun 3 July 2026 under China’s Ministry of Natural Resources, includes Russian and German scientists and aims to build a robust data base for climate research and sustainable Arctic development.

Ash from Shiveluch volcano triggered flight cancellations and delays at Anchorage, Fairbanks and Nome airports, affecting about ten Alaska Airlines flights with roughly 1,100 passengers.

An article reports that a newly identified Arctic predator could threaten the polar bears’ dominance in the region, raising questions about future ecosystem balance and impacts on local wildlife.

Researchers quantified sediment and organic‑carbon fluxes in a boreal sub‑Arctic river, revealing that climate change is driving substantial geomorphic alterations. The study highlights how shifting thermal regimes affect river morphology and the transport of carbon-rich sediments, potentially modifying downstream deposition patterns and influencing regional carbon budgets.

R/V Skagerak has left Gothenburg en route to the Arctic for a two‑month research expedition, equipped with new instruments and high expectations for scientific discovery.

ICM joins Tara Polaris I, an 18‑month research voyage that departs Lorient to investigate microbial communities across the Arctic Ocean, aiming to deepen understanding of polar ecosystems and climate impacts.

A new WRF‑Chem 4.6.1 modeling study shows that mineral dust emissions from high‑latitude sources substantially affect Arctic climate indicators, including aerosol optical depth and ice-related metrics.

According to a 2025 forest health report for the Northwest Territories, drought‑driven pest outbreaks and an established aspen disease have impacted more than 800,000 hectares of forest, while flooding has killed over 60,000 hectares along the Slave River. These findings underscore rising risks to the region’s forest ecosystems and associated economic activities.

Beaver activity has expanded into Alaska’s treeless tundra since the 1980s, creating over 10,000 ponds that are reshaping permafrost and revealing a measurable environmental shift visible from space.

A drone from a Turkish expedition captured the sea‑ice edge in Svalbard on July 16, 2026, offering new observational evidence of Arctic ice extent.

A new preprint documents highly pathogenic H5N5 infections in a polar bear and Atlantic walrus from Svalbard, showing the virus is spreading among Arctic marine mammals.

The study shows juvenile Arctic char can distinguish siblings from non‑siblings using odor cues linked to major histocompatibility complex variation, suggesting genetic immunity signals shape early social interactions.
