A U.S. Energy Department climate scientist visited Utqiaġvik to evaluate research progress on permafrost and climate change, highlighting the importance of accurate measurements and models in predicting future climate patterns in the Arctic.
The Baltic Sea's main herring stocks have fallen below target levels, which is an alarming sign of changes in the sea's ecosystem, according to WWF Finland.
Researchers say climate change is playing a big role in the collapse, which has left thousands of people along the river without the salmon they depend on.
As climate change and high costs impact Alaska's fisheries, fewer young people are entering the trade, posing challenges for the industry's future.
A research team has discovered that bottom sediment temperatures in the Russian Arctic shelf vary across different regions, with the Kara Sea having higher temperatures due to warm currents and large Siberian rivers, and the Laptev Sea and East Siberian Sea having the lowest temperatures and thicker subsea permafrost, which is important for understanding the degradation of permafrost and methane emissions in the region.
Teller is considering moving to a new subdivision site to avoid flood zones and eventually connect to water and sewer systems, with the project estimated to be completed by summer 2025.
“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,
While the ships are free to pass through the Bering Strait, its 55-mile width means that any spills would be likely to drift toward Alaska communities.
The Southeast Alaska commercial red and blue king crab fishery will remain closed for the upcoming season due to low stock numbers, although some areas have shown signs of rebounding, according to the Alaska Department of Fish and Game.
Severe Vibrio vulnificus infections in the United States are associated with warming coastal waters, with an increase in infections in the Eastern United States and an expanded geographic range.
Volunteers of the Clean Arctic project in the north of Chukotka, Russia, have removed more than 25 tons of garbage. The project aims to clean up the Arctic region and protect its fragile ecosystem. The volunteers have been working tirelessly to collect and dispose of waste, including plastic, metal, and other debris. The efforts have been successful in reducing pollution and preserving the natural beauty of the area. The project has received support from local communities and organizations, and it continues to make a positive impact on the environment.
A decline in the population of sea otters, a well-known predator of urchins and other kelp-eating critters, led to the spread of “urchin barrens” along the Pacific coast, where urchins have mowed down entire kelp forests. Now, researchers are trying to figure out if, and how, other predators such as sunflower stars could play a complementary role in protecting the kelp forests.
So far, 22 sea lions have been found, with signs of human interaction, including gunshot wounds.
Extreme weather events like Typhoon Merbok are becoming more common, and many Alaska communities are wondering about the future.
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.
Kiwi crews exposed to radiation at Mururoa Atoll hold concerns for subsequent generations.
Scientists say worsening heat waves have a clear link to climate change. This year, a seasonal El Niño pattern will also be adding fuel to the fire.
Beluga whales in Cook Inlet have been in a long period of decline, about two percent a year. But a new population count points to a reversal. The latest numbers have led researchers to declare the population stable for the first time in decades.
