Researchers found that Arctic mixed‑phase ice fog can linger 3‑5 days—far longer than expected—threatening shipping lanes and reducing the effectiveness of naval laser defenses.
A new study shows that the self‑cooling air layer protecting mountain glaciers will collapse by mid‑century, accelerating ice melt and increasing meltwater runoff, sea‑level rise, and Arctic infrastructure vulnerability.
The 2025 Arctic sea ice minimum reached 4.60 million km² on September 10, ranking tenth lowest in a 47‑year record and marking the lowest extent in the past 19 years, underscoring a rapidly changing Arctic environment.
A crew replacement took place on a Russian drifting expedition at the North Pole, marking a routine operational shift in the Arctic.
Snorri Sigurðsson, an evolutionary biologist from Iceland, has been named Chair of the Arctic Council’s CAFF Working Group, where he will lead efforts to integrate Indigenous Knowledge and advance the Action Plan for Arctic biodiversity in alignment with global frameworks.
China has built a new icebreaking research vessel to study Russia's Arctic seabed.
NSIDC’s AROSS study shows that Arctic precipitation is shifting toward more rain in summer, especially over the North Atlantic, increasing the frequency of rain‑on‑snow events that threaten reindeer herders and alter sea‑ice dynamics.
A 16‑day 2,500‑mile cruise on the Sikuliaq will deploy wave buoys, seafloor sensors, and drones along Alaska’s coast, gathering data to improve storm forecasts and hazard assessments for Arctic communities.
June's swift shift to hot, dry conditions caused a 4‑day cutoff of the Dalton Highway, halting road access to Prudhoe Bay, and ignited over 160 wildfires across interior Alaska.
Satellite data shows Bathurst caribou start migration days after snow melts, highlighting snowmelt as a key cue and underscoring climate change risks.
The Arctic Council’s EPPR Working Group has introduced the S‑COSRVA, a shoreline oil‑spill response tool that analyzes feasibility, logistics, and environmental constraints to guide responders in selecting the most suitable cleanup methods for Arctic coastlines.
Arctic wildland fires are accelerating, releasing vast permafrost carbon, disrupting Indigenous communities, and prompting the Arctic Council to launch a Wildland Fires Initiative to coordinate prevention and response.
The Arctic Council’s SAON ROADS initiative is developing a wildfire observation system that integrates indigenous knowledge, local inputs, and new modeling tools to improve fire risk warnings for Arctic communities.
The Saami Council’s co‑production projects link Sámi reindeer‑herding knowledge with science to improve climate adaptation, biodiversity management, and data stewardship in Sápmi and the wider Arctic.
Rising Arctic shipping amplifies underwater noise, disrupting marine life and Indigenous livelihoods; a new PAME report models 2030 scenarios and recommends speed limits, rerouting, and technical upgrades to mitigate impact.
The 14th Arctic Council meeting, held virtually on 12 May 2025, closed Norway’s chairmanship and launched Denmark’s, issuing the Romssa‑Tromsø Statement and outlining priorities on climate, shipping, Indigenous participation, and sustainable development.
Rain‑on‑snow in November 2021 killed hundreds of sheep in South Greenland, prompting NSIDC’s AROSS study to share adaptive strategies with Inuit herders as Arctic weather shifts.
Carbon Brief
A new Science review predicts that by the century’s end, Arctic summers will become sea‑ice‑free, Greenland’s melt area will quadruple, and permafrost will be cut by half, endangering infrastructure and communities.
Scientists use GNSS bedrock measurements to show Greenland’s meltwater storage peaks in July, compressing bedrock by ~5 mm, revealing that climate models may underestimate runoff by up to 20% during record melt years.
Climate scientist Ketil Isaksen reports record‑breaking summer temperatures in Svalbard, exceeding the 10 °C Arctic threshold, and outlines impacts on permafrost, infrastructure and the need for rapid climate action.
Earth observation satellites, led by Norway’s Space Agency, provide critical data on Arctic cryosphere changes, support permafrost monitoring, community relocation, maritime traffic, and broadband deployment, aiding climate adaptation and security.
