An amount of shoreline roughly the size of central Moscow now collapses into the sea every year.

A major source of pollution comes from wood-burning stoves. Other sources are vehicle exhaust systems, power plant emissions and heating oil. The air pollution can permanently harm respiratory function and cause other health problems.

An aerial survey of the moose population in Zone 17 and the southern part of Zone 22 carried out in 2021, shows a 35 per cent decline in moose populations, a moderate and concerning decline, says Cree Grand Chief Mandy Gull-Masty.

Pacific pink salmon (Oncorhynchus gorbuscha) were introduced in the Kola Peninsula for their valuable eggs in the 1950s. Since then, the species has spread along the entire Norwegian coast and will probably remain. This sudden increase in pink salmon numbers in Norway, thought to be linked to favourable climate conditions for pink salmon reproduction and survival, is expected to continue as water temperatures rise with climate change and large numbers of fish continue to arrive from Russia.

“While many factors, such as weather, climate change and changes to the historical extent and timing of caribou migration may be contributing to lower harvests by federally qualified subsistence users, the board should act to help ensure that rural residents are able to meet their subsistence need, and to provide for a subsistence priority,” said Thomas Heinlein, acting Alaska director for the Bureau of Land Management, during the board meeting.

Rising temperatures and dwindling oxygen levels are decimating marine species. But humanity can avert mass die-offs by curbing fossil fuel use and other planet-warming activities.

Ten electric cars including Teslas, Rivian pickup trucks and potentially Ford F-150 Lightings will drive more than 1,000 miles on the Dalton Highway from Fairbanks to the Arctic Ocean and back, to demonstrate electric vehicle technology in a remote, rugged, low-infrastructure environment.

Alaskans have shown interest in online smoke and air-quality advisories after a surge of lightning-caused fires across the Interior.

Prime Minister Justin Trudeau is convening a high-level emergency meeting to discuss the wildfire situation in the Northwest Territories. "This is an example of how bad the forest fires have become now in our country where we're seeing unprecedented forest fires ... my thoughts are with the community."

A fungus that lurks in desert soil makes thousands of Americans sick every year with a condition known as Valley Fever. Thanks to climate change, it’s spreading north.

A fire broke out on the nuclear-powered container ship Sevmorput in Murmansk, but information about the incident was scarcely communicated to the public.

Arctic soil microbes in Svalbard are equipped with enzymes to degrade carbon compounds and can adapt to climate change, potentially affecting CO2 emissions feedback loops.

The city told owners their buildings should not be occupied until snow is removed if they have a roof at risk of collapse.

To learn more about wolf diet Roffler and colleagues used a new technique called DNA metabarcoding. This technique identifies prey species by DNA found in scats.
