The oranging of northern rivers seems to be related to recent permafrost thaw that has allowed streams to release previously captive iron, trace metals and acid.
The Wrangell landslide tragedy underscores Alaska's challenge in landslide prediction due to insufficient monitoring and data collection.
The Little Diomede school is closed indefinitely after a collapsing city building, with rotted stilts, leaned on it, causing no injuries but prompting a switch to video conference classes and relocation of teachers.
Due to recent flooding, FEMA assessors will work with state, local and tribal officials to determine if federal aid is warranted with flood and erosion damage.
“We started seeing structural timber,” one resident said. “And then I was like, ‘Oh, my God. That’s from houses upstream.'”
Scientists from Moscow State University have studied the Lorino cliff in the Chukotka region and discovered that the rapid retreat of the coast is due to the reduction of sea ice, and they recommend that villagers prepare for the transfer of coastal structures further inland.
The damage wrought to the park’s road by melting permafrost is creating a new reality affecting visitors, park staff, local businesses and potentially wildlife.
A research project found that the Bering Strait is at least a meter deeper on the Alaska side than previously believed, according to the National Oceanic and Atmospheric Administration’s Alaska Fisheries Science Center. The project evaluated new and old bathymetric surveys, applying modern technology to the latter to more accurately pinpoint locations.
Following a thaw slump, the water becomes cloudy and full of sediment, potentially suffocating the eggs of spawning sheefish. Scientists are concerned that permafrost thaw could lead to declines in the sheefish population, a staple food for many Alaskans.
Taking care of Hawaii's unique natural environment takes time, people and money. Now Hawaii wants tourists to help pay for it.
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.
Warming soils beneath Utqiagvik are triggering erosion that threatens homes, infrastructure and cultural resources. The North Slope has seen some of the fastest changes in coastal erosion in the nation.
The Arctic hamlet of Tuktoyaktuk, N.W.T., is collapsing into the ocean as it loses up to a meter of coastline each year. The people who live there are in a race against time to preserve their way of life — and their community — before it is washed away.
Anchorage’s backyard wilderness is experiencing a surge in users that shows no signs of letting up. Driven in part by social media and location tracking apps, more people are recreating in historically less-used parts of the park than before.
Protecting the coast of Tuktoyaktuk from the onslaught of climate change is estimated to cost at least $42 million and is only guaranteed to last until 2052. Over the project’s 30-year lifespan, over 60,000 cubic metres of sand are expected to be brought to keep the beach intact.
Approximately 31 Alaska Native communities face imminent climate change due to floods and erosion. This can lead to the disappearance of culture and lifestyle changes. The four tribes are in the process of relocating from a rapidly disappearing village.
A contractor tore down six structures in the past few weeks, part of a process to remove erosion-threatened places that began almost a decade ago.
A researcher's quest to understand a mysterious mass extinction leads to cud-chewing culprits.
Líídlįį Kúę, in Dene Zhatie, means the place where two rivers meet. It has been a place for Dene to gather for millennia. It is also an area prone to flooding, sparking concern about how the community will be impacted by spring break-up, during a year of high water levels.
