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.
The virtual reality project Qikiqtaruk: Arctic at Risk is transporting people to Yukon's northernmost point without them ever having to leave home.
Rick Thoman is thinking hard about the cost of climate change and the benefits of better tracking, potentially influencing Alaska’s response to extreme weather and more.
Scientists found that the glaciers are triggering the release of methane, a potent greenhouse gas that causes global temperatures to rise.
