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.

Ukrainian drones attacked the Makhachkala commercial seaport and the Avarsky Theater in Dagestan, causing fires but no casualties, while maritime drones hit Sochi, injuring 28 people and damaging beach infrastructure. Satellite data also shows thermal anomalies at a compressor station in the Yamalo‑Nenets Autonomous District, suggesting possible damage to a key gas pipeline facility.

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.

DNA analysis has identified the identities of four sailors lost in the 1859 Franklin expedition, resolving a 166‑year‑old mystery.

Researchers at the University of Waterloo used DNA from living descendants to match four skeletal remains of Sir John Franklin’s 1845 Arctic expedition, including Harry Peglar, confirming identities and shedding light on the final escape attempt.

Scientists from Aarhus University revealed that the narwhal’s straight, spiraled tusk is held by opposing spiral collagen layers, a discovery that not only explains a key Arctic marine adaptation but could inspire new composite materials.

IUCN has reclassified three Arctic seal species as Near Threatened, up from Least Concern, citing sea ice loss driven by global warming as the main threat.

Scientists demonstrate that past orbital warming and future greenhouse‑gas‑driven warming can produce comparable summer sea‑ice loss, both linked through shifts in surface energy seasonality.

James Schaefer of Trent University is leading a study on how tundra plant communities on Victoria Island have evolved over the past 30 years amid Arctic warming.

A 3D fossil of an ancient animal was uncovered in a Norwegian Arctic sheep field, marking the first new major 3D fossil site there and offering fresh evidence of early Arctic life.

A magnitude 6.3 earthquake struck south of Nikolski on Sept. 3, part of a swarm that began Aug. 31, with eight magnitude‑5 or greater events recorded this week.

Vaisala will host a webinar on environmental intelligence for Arctic maritime operations, highlighting how expanding Arctic activity demands clearer operational insights to coordinate vessels and crews.

Researchers introduced an objective method that categorizes the Arctic into four climate types—cold‑dry, semi‑cold‑dry, semi‑warm‑wet, and warm‑wet—and mapped their spatiotemporal evolution, offering a clearer framework for assessing climate change impacts.

A new genetic study indicates that ancient variants carried by Greenlandic Inuit may heighten the risk of modern diseases, highlighting the need for targeted health research in this isolated Arctic population.

The study shows that Arctic amplification and surface boundary changes reduce the meridional geopotential height gradient aloft, offering a possible link between North American cold waves and Arctic sea ice fluctuations.

India can broaden its Arctic engagement through the BRICS Working Group on Ocean and Polar Science and Technology, but the country cannot replace the Arctic Council as a primary governance body.

A new Special Theme titled ‘Changing Arctic Coasts: Physical Drivers, Coastal Resilience, Governance and Socio‑Ecological Impacts’ is now open for submissions, encouraging research into coastal dynamics, resilience strategies, governance frameworks and their socio‑ecological effects across the Arctic.

Arctic sparrows have only a few weeks each summer to establish territories, mate, lay eggs, and raise chicks, underscoring the species’ vulnerability to climate‑driven changes in the region.

Scientists are probing whether rapid evolution in five core species can let Alaska’s North Slope ecosystem weather faster Arctic warming, combining genetics, diet tracking, and water‑flow monitoring in a $15 million NSF‑funded Evome study.

Professor Timothy Pasch has spent over 25 years researching the Arctic.

Summer 2026 saw unusually high temperatures across the Arctic, with parts of Siberia recording three‑month averages exceeding 5 °C above typical values—an indication of the region’s accelerating warming trend.

Eight research consortia were awarded funding under the Arctic and Mind STN programmes, and new programme directors were appointed, bolstering scientific collaboration and research capacity in the Arctic region.
