A paddler shot and killed a protected polar bear near the mouth of Seal River on the Hudson Bay coast west of Churchill, Manitoba. The incident is under investigation by provincial wildlife officials and highlights how changing ice conditions may be increasing human‑bear encounters along the northern coastline.

Polar cod stocks have fallen sharply in West and East Greenland since the early 1990s, with the species moving north as warming waters shrink sea ice—a trend that already forces fishermen to shift bait choices and threatens ringed seal and broader marine food chains.

The study finds that predation patterns in sub‑arctic soft‑sediment ecosystems vary depending on both the number of crustacean predators present and their species composition, indicating a complex regulatory dynamic within these habitats.

A recent UNESCO inspection of Wood Buffalo National Park found progress under Parks Canada's $87 million action plan minimal since 2022, while Canada and Alberta push oil sands pipeline plans that critics say threaten the park’s delta ecosystem.

Wildfires now cover about 3.5 million acres across Russia’s Krasnoyarsk region and Sakha republic, driven by extreme summer heat and mass infestations of the Siberian silk moth that have left large amounts of dry deadwood vulnerable to fire.

The shallow soil layer above Canada’s permafrost means black spruce roots grow close to the surface, making them vulnerable to thawing conditions that could destabilize these forests.

Researchers show that where Arctic‑breeding shorebirds originate and how they refuel during migration influence their mercury load, a key concern as global shorebird numbers dwindle.

Growing drunken forests above thawing permafrost are becoming more common across Canada’s Arctic, illustrating how climate change alters northern ecosystems and highlighting challenges in monitoring these changes.

A nuclear‑powered Russian ship has navigated the Arctic sea lanes, a development driven by climate‑induced ice loss that is creating new potential shipping corridors for China and other nations.

Three independent studies show Hudson Bay’s ice conditions and modern vessel capabilities now allow year‑round shipping through Churchill, paving the way for Canada to expand its northern trade corridor and boost exports beyond the U.S.

Photographer Piet Van Den Bemd’s collection shows polar bears moving across diminishing pack ice while nearby glaciers visibly recede, underscoring the visual evidence of Arctic climate change.

Students guided by Quinton examine how thawing permafrost reshapes Canada’s Arctic terrain, noting changes already affecting nearby communities.

Paul Fuhs says Alaska’s pollock trawl fleet is managed conservatively and its mortality is largely due to cannibalism, not human harvest or bycatch. He rejects Whit Fosburgh’s comparison with East Coast fisheries and argues for practices that reduce bottom‑trawling impacts while maintaining sustainable yields.

Understanding how rising temperatures affect the immune resilience of endangered Arctic charr informs conservation and fishery management in a warming Arctic ecosystem. In Finland, these fish are farmed mainly to stock wild populations.

A small expedition vessel circumnavigated Svalbard, documenting polar bears, walruses and seabirds as evidence of its fragile Arctic ecosystem.

A golfer named Billy Joss played the world’s northernmost golf course in the remote Inuvialuit community of Ulukhaktok, Northwest Territories—an experience that highlighted the unique recreational possibilities and potential economic benefits for this High Arctic settlement.

As Arctic ice melts, a once‑barely usable sea passage is becoming viable for faster shipping between Asia and the rest of the world, attracting interest from freight operators while heightening threats to whales and marine ecosystems.

New research from Simon Fraser University indicates Arctic landscapes are eroding faster than previously estimated, largely due to climate change.

India has joined China and South Korea in pursuing new Arctic shipping routes, citing melting ice that opens commercial corridors as climate change enables. The move signals growing Asian interest in the region’s strategic maritime lanes.

A walrus caught in Naujaat was found carrying trichinella roundworm, prompting Nunavut Health officials to urge residents who ate the uncooked meat to seek medical care and recommend testing and proper cooking before consumption.

Scientists have introduced a new adaptive multimodal fusion network that enables fine‑grained analysis of Arctic sea ice. By integrating diverse data sources, the tool improves tracking of how sea ice regulates global heat, carbon, and freshwater.

Canada’s new defense spending plans would deploy technology to detect whales and submarines in Arctic waters, offering northern communities enhanced surveillance and environmental monitoring as part of a broader focus on Arctic sovereignty.

Smoke from large wildfires in North America, Eurasia, and Indonesia has spread across the Northern Hemisphere, reaching the Arctic and influencing its environmental conditions.
