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.
Arctic species are currently under multiple pressures and several are red-listed. Adaptive ecosystem-based monitoring and management applied to the critically endangered arctic fox in Finnmark, illustrates how such pressures can be uncovered and potentially mitigated.
With Arctic permafrost thaw rapidly outpacing projections, researchers are racing to understand the impacts of an increasingly unstable future.
The State of Alaska recently received $38 million from the Department of Housing and Urban Development to ease the burden of climate change. The money was made available through the Community Development Block Grant Disaster Recovery Program. These funds are aimed at helping communities better rebound from presidentially declared disasters, but Salazar says the state will be allowed to allocate the new funds for preventative measures.
The relocation between from Newtok to Mertavik has taken time and community members stay patient as local, state, and federal agencies figure out the complex funding and logistical hurdles.
Taking care of Hawaii's unique natural environment takes time, people and money. Now Hawaii wants tourists to help pay for it.
Coordinating teams to collect and sort marine debris, plus shipping it to a landfill or recycling center is an expensive logistical nightmare as Alaska waters increase with marine debris.
"Siku" means sea ice in the Siberian Yup'ik language. But about a hundred other Yup'ik words describe different types of sea ice, including icebergs, floating pressure ice ridges, solid ice safe for travel — and "pequ," "an unsuitable area in ice field where the current causes ice to heave up or break up," Vera Metcalf said.
Story telling provides a powerful tool in a changing climate. Epen Hobson has been experiencing the land and ocean through the perspective of an Inuit photographer and hunter. A recipient of the Arctic Resilient Communities Fellowship he shares, "We're an oral people, we tell stories, we teach by telling stories," The effects of climate change are concrete and dramatic for the Arctic communities such as Utqiagvik, and Hopson is hungry to see infrastructure and policy solutions to address them.
In 2016 Renato Alberti, who had overseen the structure for 35 years, noticed a vertical crack in one of the outer walls. Alberti, now age 67, filled the gap with repair foam, but the crack reopened after only a few days. Alberti thought something unusual must be happening. Perhaps the mountain was becoming unstable.
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.
The government of Nunavut has once again flipped its position on resource development on caribou calving grounds, now supporting a "prohibition of development within calving grounds and key access corridors, with seasonal restrictions on activities in post-calving grounds."
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.
Take a typical Alaska cruise and see the damage in its wake. Waste-water disposal to on board garbage piles up leaking into the natural environment and local waste sites. Noise pollution from the ships impact whales and other species that rely on sounds for communication. Total visitors from the industry impact on small communities has pros and cons. The evidence is clear: the industry needs an overhaul.
World leaders already have many options to reduce greenhouse gas pollution and protect people, according to the United Nations report.
Trapped in all that permafrost is an estimated 30 billion tons of carbon. It’s an unfathomable amount, Kirkwood says. With global warming, the permafrost is thawing, threatening to release a “carbon bomb” of heat-trapping methane gas into the atmosphere. But there’s something else lurking in the permafrost that has the potential to be more immediately dangerous to the people and wildlife living in the area: mercury.
Oulu has more than 900 kilometres of separated bike paths, which is comparable to Montreal. In the winter, the city plows this huge bike network by 6 a.m. every day and will plow multiple times a day if needed.
A video of the reindeer on the steps of the wind turbine has caused wonder. Aren't the animals intimidated by wind power anyway? Here are some reasons why it is so difficult to find clear facts and secure figures.
