Arctic rivers are undergoing significant changes due to a warming climate, with increased precipitation and permafrost thaw leading to stronger flows and altered chemical compositions.
The Alaska Arctic Observatory and Knowledge Hub and the Native Village of Kotzebue deployed an under-ice oceanographic instrument to monitor ice thickness and snow depth at a site offshore of town.
Conservationists petition for federal protection of the rare Kigluaik buttercup, threatened by climate change and proposed mining activities.
NASA's PACE satellite, designed to study ocean biology in unprecedented detail, has been successfully launched to enhance understanding of Earth's changing climate and improve weather forecasting.
Idaho's Panhandle is experiencing near record-low snowpack levels, with persistent dry conditions and forecasts suggesting a continued negative impact on snowpack development.
A Dartmouth study reveals a significant decline in New England's snowpack, with many river basins losing over 10% per decade due to human-caused climate change.
The new children's book combines traditional knowledge and scientific research to tell the story of a ringed seal pup in Kotzebue, Alaska, with a focus on the impact of climate change.
Two local governments have retracted their criticism of Conoco's Willow project, now focusing on protecting subsistence resources and leveraging project opportunities.
Kotzebue Elder Gladys I’yiiqpak Pungowiyi said that over the years, many skilled hunters were lost when they went out hunting and fell through the ice. I’ve been called to pray for people that are affected mentally.”
A study reveals that increased ship noise in the Arctic disrupts the behavior and communication of marine mammals, impacting local wildlife and indigenous hunting practices.
The U.S. Forest Service has finalized a plan to revamp Juneau's Mendenhall Glacier Recreation Area, addressing tourism growth and community concerns.
The 2023 Arctic Report Card highlights unprecedented summer warmth, ecological shifts, and the integration of Indigenous knowledge in understanding and adapting to climate change impacts.
Alaska communities are facing significant challenges due to climate change, including the disappearance of snow crabs, threats to subsistence hunting and fishing, and difficulties in processing and storing food, but some communities are taking action and developing local climate adaptation plans with the support of funding and collaboration between different governments and agencies.
Wildlife surveys in southwest Yukon have shown a 'concerning' decline in the number of Dall sheep — and biologists say recent snowy winters may be to blame.
A new study reveals that four dozen Antarctic ice shelves have shrunk by at least 30% since 1997, with 28 of them losing more than half of their ice, raising concerns about sea level rise due to climate change.
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.
“Particularly when it comes to the topmost 20 metres of the water column, just below the sea ice, there was no available data on the zooplankton,” Hauke Flores, a researcher from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI),said in a statement. “But it’s precisely this hard-to-reach area that’s most interesting,
The Permafrost and Infrastructure Symposium this month brought together over 50 scientists, engineers and residents this month, creating a space for them to exchange their perspectives on the effects of thawing permafrost in the Arctic.
Satellite images from NASA show the alarming and above-average ice loss in Greenland due to rising temperatures, with significant melting and a transformation of the snow cover observed during the 2023 melting season.
The forces of climate change that are reducing ice cover and opening up the Arctic to more activity are making Alaska more important in regards to Homeland Security. For the Department, which has a combination of public safety, emergency response and law-enforcement functions, climate change is creating new challenges for which old responses are no longer adequate.
