Alaska’s black‑capped chickadees are showing a sudden increase in beak deformities that resemble fishhooks, with sightings rising from a handful in 1991 to hundreds across Southcentral Alaska, raising concerns among biologists about potential environmental causes.

The review synthesizes historical records of Arctic mosquitoes from early expeditions to today, highlighting taxonomic gaps, limited data, and the need for updated surveillance to evaluate climate‑driven shifts and arbovirus risks.

Polish researchers identify a new tardigrade species, Paramacrobiotus klimaszyki, from leaf litter on Spitsbergen, marking the 100th tardigrade species recorded in Svalbard and the first new species discovered in deciduous leaf litter there.

Since April, at least 19 people have died from brown bear attacks across Russia’s Far North, Siberia and Far East, prompting compulsory mandatory obligations and calls for mandatory precautions by authorities.

Agnico Eagle Mines finished construction on Pistol Bay Falls in summer 2026, modifying natural barriers to give Arctic char better access to upstream spawning and overwintering habitat near Rankin Inlet, with a ten‑year monitoring plan.

Arctic sea ice is rising again after hitting its yearly minimum, while shipping on Russia’s Northern Sea Route has surged to a record high of more than 50 vessels—including over 30 tankers—highlighting Russia’s intent to boost Arctic cargo throughput amid a new EU ban that will redirect LNG exports eastward.

Norwegian researchers found large numbers of juvenile Atlantic cod in Svalbard fjords, suggesting Atlantic species are moving north as Arctic waters warm.

This is an unedited video of a large glacier calving in Svalbard. I recorded this during ...

Three polar bears were photographed on the Beaufort Sea coast within the 1002 Area of the Arctic National Wildlife Refuge.

Former Finnish President Sauli Niinistö, in his book, stresses climate change as the primary threat to the Arctic, reflecting on his decade‑long diplomatic efforts amid rising security tensions, a cancelled summit, a black‑carbon campaign, and Finland’s transition into NATO.

Short‑tailed shearwaters migrate annually from southern Australia to the Bering/Chukchi Seas, historically bringing over half a million birds per day to Gambell in late August/September. Since the 2019 mass‑mortality event linked to warming waters and dwindling krill, daily counts have fallen to below 100 000 but tens of thousands still pass each day. The 2019 die‑off, the largest recorded, was primarily due to starvation amid reduced sea ice and altered food‑web dynamics.

The exhibition displays artist‑generated maps that illustrate radium‑isotope data indicating chemical changes in the Arctic Ocean.

A reconstructed bridge over the Redknife River has reopened, allowing traffic and restoring seasonal fish passage to a culturally significant Dene site.

A devastating storm that displaced over 1,500 people and destroyed villages in Western Alaska prompted residents of Kipnuk and Kwigillingok to relocate, a situation highlighted in award‑winning reporting by Yereth Rosen.

The preprint uses variable‑resolution climate models calibrated with CMIP6 Arctic and Antarctic storylines to show that storyline‑based lower‑boundary forcing influences future climate responses more strongly than horizontal resolution, with Arctic low‑level temperature and humidity dominated by the storyline and Antarctic precipitation and wind better captured under the storyline scenario.

The DEW Line was a network of 63 radar stations linked along the 69th parallel from Alaska to Baffin Island, built after a 1954 US‑Canada agreement and formally handed over on 15 April 1957; it was designed to detect bomber aircraft and became obsolete against missiles, ultimately replaced by the North Warning System in 1993.

Greenland inaugurated Pilivik National Park, covering 22,249.8 km² between Kangerlussuaq and Disko Bay, and combining nature protection with traditional hunting and fishing.

Research shows that thinner, mobile Arctic sea ice near Wrangel Island can accumulate, creating unpredictable hazards and increasing icebreaker dependence.

Sierra Club volunteer Gary Keir highlighted the vulnerability of Alaska’s Brooks Range to oil development at a Patagonia store event in Manhattan, urging support for the group’s opposition to lease sales.
