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.
Climate change has been observed for hundreds of years by the plant specialists of three Odawa Tribes in the Upper Great Lakes along Lake Michigan. Sleeping Bear Dunes National Lakeshore is the focus of two National Park Service (NPS) studies of Odawa Traditional Ecological Knowledge (TEK) of plants, ecosystems, and climate change. Data collected during these studies contributed to developing Plant Gathering Agreements between tribes and parks. This analysis derived from 95 ethnographic interviews conducted by University of Arizona (UofA) anthropologists in partnership with tribal appointed representatives. Odawa people recognized in the park 288 plants and five habitats of traditional and contemporary concern. Tribal representatives explained that 115 of these traditional plants and all five habitats are known from multigenerational eyewitness accounts to have been impacted by climate change. The TEK study thus represents what Native people know about the environment. These research findings are neither intended to test their TEK nor the findings of Western science.
Questions still linger about what caused the bear to kill a woman and her baby — but more important for Wales is the question of how to move on.
Scientists say climate change appears to be a factor making Florida and other parts of the U.S. welcoming to non-native mosquitoes.
World leaders already have many options to reduce greenhouse gas pollution and protect people, according to the United Nations report.
Some of the world's leading makers of flu vaccines say they could make hundreds of millions of bird flu shots for humans within months if a new strain of avian influenza ever jumps across the species divide.
The recent death of an 11-year-old girl in Cambodia's Prey Veng province infected with avian influenza has reinvigorated concern over the virus potentially gaining the ability to spread among humans. And while experts maintain the risk of that happening "remains low" at this time, the World Health Organization has said that increasing reports of avian influenza infection in humans are "worrying."
This weekend marks the third anniversary of the World Health Organization’s declaration of the global pandemic — and Juneau’s wastewater is awash with COVID.
A new variant of bird flu has recently infected both sea lions and mink. Health authorities around the world are now monitoring that it does not begin to infect humans.
There’s an old saying that captures the essence of subsistence harvesting: “When the tide is out, the table is set.” Clams, mussels and other food are available for the person. Climate change has impacted subsistence in the ocean and on the land. Community members share observations on changes.
The petition is the latest step in a long effort to better protect oil spill responders from a range of long- and short-term health problems suffered after BP’s Deepwater Horizon oil disaster in 2010 and other spills.

A polar bear that killed a young mother and her baby last month in western Alaska was likely an older animal in poor physical condition.
Atmospheric rivers, those long, powerful streams of moisture in the sky, are becoming more frequent in the Arctic, and they’re helping to drive dramatic shrinking of the Arctic’s sea ice cover.
Harmful algal blooms will become a more common feature of a warming Arctic. Last summer, a massive bloom was detected off the coast of Western Alaska, almost by chance, when scientists sailing through the Bering Strait and Chukchi Sea found worryingly high levels of Alexandrium catenella.
We (Norway) need to build solar power, at a pace we have not seen before, according to the Energy Commission. And the industry believes a 33-fold increase in seven years is realistic.
About 25 kg of sticky mass from a company entered the sewage system. Sewage goes into the sea from operating plant impacting fish and other sealife.
The nation's six million feral pigs are destroying crops and preying on endangered species. But the most serious threat they pose is to human health.
The decision caps a decades-long battle over a region that is home to both the world’s largest wild salmon run and one of the world’s largest deposits of copper and gold.
