The Environmental Protection Agency has determined that lead emissions from small planes pose a threat to public health, potentially leading to the agency's first-ever limits on lead fuel in aviation.
Unalaska in Alaska is under an air quality advisory due to ashfall from the eruption of Mount Shishaldin on Unimak Island, with the advisory extended until Thursday.
Scientists warn that methane trapped beneath the Greenland ice sheet could intensify climate warming as the ice melts, releasing the potent greenhouse gas into the atmosphere at accelerating rates.
Wildfires in the N.W.T have emitted 97 megatonnes of carbon into the air so far this year according to the Copernicus Atmosphere Monitoring Service. That's 277 times more than what was caused by humans in the territory back in 2021.
The temperature of asphalt and pavement and concrete and sidewalks in Arizona on a warm sunny day or summer afternoon is 180 degrees sometimes.
Clean, fresh air can be part of the draw for tourists to Canada's North — but they won't find it this week in Yellowknife due to wildfire smoke.
Wildfire smoke has been blasting much of the N.W.T. lately, with air quality advisories in nearly every community Tuesday morning. Meanwhile, much of the territory is also coping with record-breaking heat.
People in Southeast Alaska are starting to see smoke from Canada's record-breaking wildfire season — and there’s more to come. The air quality levels are still fair: hovering around 17, on a scale that goes up to 300.
Shishaldin is one of the most active volcanoes in the Aleutians — it’s had nearly 30 eruptions since 1824.
The virtual reality project Qikiqtaruk: Arctic at Risk is transporting people to Yukon's northernmost point without them ever having to leave home.
Heat waves like the one that engulfed parts of parts of the South and Midwest and killed more than a dozen people are becoming more common.
As the Fairbanks North Star Borough continues to tweak plans to improve air quality in its nonattainment zone, its wood stove change-out program continues to grow.
A study by the Yukon-Kuskokwim Health Corp and the CDC found that COVID vaccination was 92% effective in preventing hospitalizations and extremely effective at preventing symptomatic cases among the mostly Yupik residents of the region, with booster shots restoring protection against symptomatic cases.
“This is the first time that we’ve sent a crew to Canada in May,” said Lily Coyle with the Alaska Division of Forestry and Fire Protection.
Dr. Micah Hahn received an EPA grant to make air quality and health data easier to access in rural Alaska.
A long, thin cloud of ash began drifting toward the Aleutian Islands on Wednesday and continued east toward the Gulf of Alaska, where it caused major disturbances for air traffic starting Thursday. Volcanic ash is a danger to planes because it is abrasive and can cause engines to fail. Alaska Airlines canceled 51 flights that day, the company said in a statement. Alaska Airlines canceled 11 flights by 6 a.m. and said more are possible, with delays likely through the day.
Due to ash from the volcano in Kamchatka, Russia, Alaska Airlines canceled eight flights Wednesday between Anchorage and Western Alaska airports in Adak, Bethel, Dillingham and King Salmon.
The Copper River Basin in Alaska has experienced less reliable snow and ice conditions in recent years, impacting winter activities such as trapping, hunting, and gathering firewood. This study, based on nine oral interviews with local residents, reveals that crossing rivers has become more treacherous and difficult, with significant changes in ice conditions observed since the 1970s. Decreased snowpacks and increased shrub growth have also posed obstacles for accessing winter trails, requiring individuals to cut through forests. These changes, combined with socio-economic and technological factors, have affected the way people engage in winter activities in the Copper River Basin. Overall, this research contributes to the understanding of climate change's impact on winter activities in Alaska and the Circumpolar North.
World leaders already have many options to reduce greenhouse gas pollution and protect people, according to the United Nations report.
