Smoky air reached an AQI of 10 on July 19 in Yellowknife, forcing an Inuvialuit celebration at Somba K’e Park to relocate indoors and prompting the NWT’s chief public health officer, Dr. Kami Kandola, to urge masks, ventilation, and cooling strategies for vulnerable residents amid rising heat and pollution.

Indigenous peoples gathered in Geneva urged the United Nations to give them greater voice on climate impacts affecting their lands, citing rapid Arctic warming that threatens reindeer herding in Finland and calling for new accreditation mechanisms and funding pathways.

Eider ducks, walruses and gray whales hunt crustaceans on the seafloor, a feeding behavior that could be disrupted by warming waters and shifting prey availability in the Arctic.

Environment Canada has issued an orange rainfall warning for Fort Good Hope, Paulatuk and Colville Lake in the NWT, forecasting 50‑80 mm of rain—up to 100 mm locally—and possible snowfall as temperatures fall. The heavy precipitation could cause localized flooding, make roads impassable and damage critical infrastructure.

Sally Anderson incinerated garbage at Toolik Field Station on June 25, 2026, producing a ribbon of smoke over the Arctic Circle—a routine task that maintains the facility’s research activities and mitigates waste buildup.

The study uses C- and L-band Synthetic Aperture Radar to detect seawater flooding on first-year Arctic ice near Qikiqtarjuaq, Nunavut, evaluating how well these radar frequencies identify slush before the melt period.

Anchorage Daily News opinion piece questions whether Panthera can defend its wild‑cat conservation claim while board members profit from the proposed Donlin Gold mine that threatens lynx habitat and Indigenous lands in Alaska’s Kuskokwim region.

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.

Smoke from a nearby wildfire still blocks Transport Safety Board investigators’ helicopter access to the wreckage of a Buffalo Airways firefighting aircraft that crashed near Fort Simpson on June 24, delaying recovery and analysis of parts that may lie in a lake. Investigators plan another attempt in weeks.
