Experts are warning about the negative health impacts from air pollution as we head into wildfire season — and new research suggests it could exacerbate severe outcomes from COVID-19 and increase the risk of lung disease.

There are more than 20 invasive plant species in the Yukon that spread, change the makeup of the soil and generally prevent native plant species from thriving in their natural environment. here's what you can do about six of the most common ones.

Biologists want to know why there are so many moose. It may have a lot to do with shrubs — moose feast on their leaves during the spring and summer. These short woody plants are spreading west, aided by climate change, and moose populations are expanding along with them.

Federal regulators have approved a plan to demolish four Klamath River dams, a historic act that is intended to save imperiled salmon. “The Klamath salmon are coming home,” Yurok Tribe Chairman Joseph James said in a statement. “The people have earned this victory and with it, we carry on our sacred duty to the fish that have sustained our people since the beginning of time.”

Powerful underwater explosions were detected in the Baltic Sea at the end of September, near the Danish island of Bornholm. Explosive substances were found on several of the objects encountered during the crime scene investigation in the Baltic Sea, Swedish security police say.

Canada’s Western Hudson Bay polar bear population has fallen 27 percent in just five years, according to a government report released last week, suggesting climate change is impacting the animals.

The clam population crashed on the east side of Cook Inlet about a decade ago and has been slow to bounce back.

St. Jude Children's Research Hospital scientists discovered how the current epizootic H5N1 avian influenza virus (bird flu) gained new genes and greater virulence as it spread west. Researchers showed that the avian virus could severely infect the brains of mammalian research models, a notable departure from previous related strains of the virus.

Global average temperature exceeded previous record by substantial margin

A pilot program in Alaska lets firefighters tackle fires deep in the wilderness that burn carbon and speed climate change and don’t just threaten homes and lives.

Shaktoolik, a village in Alaska, is still waiting for aid from FEMA to rebuild a protective berm that was destroyed by a typhoon, leaving the community vulnerable to storms and erosion.

Berry pickers have long reported that the number of wild berries has been diminishing, and a 26-year study is now confirming the unexplained decline.

The $100 million Pretty Rocks Bridge will cross the site of a landslide that has closed the road at Mile 45 since 2021.

Bristol Bay’s prolific salmon runs are also made possible because of the effective and transparent management of the Alaskan salmon fishery, according to both Hill and Schindler. Decisions are made in real time, on the ground — or, to be precise, overlooking the water — compared to the much more cumbersome and bureaucratic Canadian system.

Late last year, four people in the Sea to Sky corridor developed encephalitis after being infected with California Serogroup viruses (Snowshoe Hare and Jamestown Canyon viruses). Vancouver Coastal Health is launching a mosquito surveillance pilot in the Sea to Sky corridor after four locally acquired encephalitis cases linked to California Serogroup viruses.

An assessment by geotechnical experts will need to be completed in order to know the stability of the slide and understand continuing risk.

The rapid pace of climate change is affecting the Arctic at a more accelerated pace than anywhere else in the world.

Hail severity will increase in most regions of the world while Australia and Europe are expected to experience more hailstorms as a result of climate change, an international review led by a UNSW Sydney researcher has found.

An evacuation alert has been issued by Yukon Emergency Measures Organization for areas of Tagish, Marsh Lake and Lewes River Road. This alert is due to high water and flooding in the areas. Water levels have exceeded what they were in the 2007 flood.
