New research shows microplastics now act as active geophysical agents that modify Arctic climate feedbacks.

Arctic sea ice loss is reducing the region’s natural cooling, as dark water now absorbs more sunlight. Scientists in Britain are exploring ways to counter this by artificially dimming incoming solar radiation.

Fort Simpson’s evacuation order was downgraded to an alert after wildfire FS016, allowing residents to return at their own risk while crews mop up the blaze and staff prepare Yellowknife’s evacuee multiplex for reopening. Power outages lasting up to 13 days were reported but can be checked locally.

An unusually intense summer of polar bears visiting eider nests in Kongsfjorden reached the highest recorded level—30 days of presence between June and July—correlating with a 28% drop in nesting ducks amid record low sea ice.

The partnership merges Mila's artificial‑intelligence tools with PolArctic’s traditional insight and marine science to refine predictions of high‑latitude sea‑ice conditions.

The briefing argues that regulating polar fuels is required because the Arctic high‑temperature fuel oil ban does not eliminate use of all residual fuels, leaving significant black‑carbon emissions unaddressed.

The GNWT and Canada Water Agency signed a non-binding two-year memorandum to strengthen collaboration on northern waters, aiming to improve data sharing, research, and stewardship of the Mackenzie River Basin while integrating Indigenous knowledge and science-based decision-making. The agreement underscores the role of Indigenous knowledge in guiding policy and aims to enhance water quality monitoring.

Senators Huffman and Heinrich are seeking answers from the Trump administration on a federal proposal that would fast‑track oil drilling in Alaska’s Western Arctic by removing key environmental protections.

Wildfires across the NWT now cover over 1.7 million acres, with 180 out‑of‑control fires threatening Wrigley and Fort Simpson as strong southerly winds push blazes closer to communities.

Researchers measured mercury concentrations and stable isotope signatures on the Greenland Ice Sheet, revealing it as an under‑characterized source of mercury that can enter Arctic marine systems through ice‑to‑ocean pathways.

Mid‑July 2026 observations show the Arctic’s Pacific‑side ice extent higher than average, while the Atlantic sector’s edge remains well north of the 1981‑2010 median.

A wildfire north of Wrigley has moved roughly one kilometre closer to the community as temperatures topped 30 °C under extreme fire‑weather conditions, prompting continued evacuation orders for Wrigley and Fort Simpson.

The article describes the calving process of glaciers in northwestern Greenland, detailing how rising temperatures accelerate iceberg formation and contribute to sea‑level rise.

Water fixtures at Inuvik’s East Three Elementary and Secondary School tested positive for lead concentrations exceeding Health Canada limits, prompting removal of affected fixtures and provision of alternative drinking water while the broader Northwest Territories school‑wide testing program continues to address older plumbing in high‑north schools.

Clean Arctic completed its first mission in Svalbard, deploying fifteen volunteers to collect and remove litter across the archipelago, highlighting a growing international environmental cleanup effort in the region.

Real Ice is testing a sea‑ice thickening technique off the coast of Ikaluktutiak (Cambridge Bay), hoping to bolster fragile Arctic ice and protect local communities.

The study applies diffusion‑based super‑resolution to satellite images, producing finer estimates of landfast sea ice roughness that support better climate models and safer Arctic over‑ice operations.

The piece describes how Yellowknife’s expanding urban farm and garden network—backed by a four‑year Sir Wilfred Laurier University research initiative—are addressing rising food insecurity caused by Arctic supply‑chain disruptions, fires, and flooding.

Typhoon Halong remnants struck Alaska’s Yukon‑Kuskokwim Delta in October 2026, flooding Kwigillingok and Kipnuk villages and displacing over 1,600 residents. The disaster has sparked rising mental‑health crises among evacuated youth, prompting calls for expanded support and policy action.

Researchers uncover a quasi‑oscillatory semidecadal pattern in the Arctic Oscillation that closely links to Asian‑Pacific summer monsoons before and up to one year after convection peaks, offering fresh insights into high‑latitude climate dynamics.

A 12‑day Students on Ice voyage from Greenland to Iqaluit brings former Environment Minister Steven Guilbeault and Inuvik teen Reese Wainman together to discuss climate impacts observed along the route, while urging Canada’s federal government to balance northern investment with stronger emission reductions.

An international team of about 80 scientists aboard the polar research ship RSS David Attenborough will sail to Greenland for a five‑to‑six‑week study of rapid glacier melt and its potential to disrupt Atlantic ocean currents that regulate Europe’s climate, feeding new data into climate models and early‑warning systems.
