Retreating sea ice in Arctic affecting zooplankton behaviour
“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,

As climate change transforms the Arctic, Homeland Security must adapt, official says
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.

Tiny but tenacious: arctic-alpine plants are engineers and warning bells
When most people consider the arctic, or high-altitude mountain landscapes, they think of endless snow, ice and bare rock. But pastel-coloured flowers, sometimes just a few millimetres wide, bloom in these dramatic places too. The miniature flowers not only weather some of the toughest habitats on Earth, but can also help engineer the landscape for other species.

Snowverloaded: Kenai Peninsula residents deal with extended winter

Sea ice loss affects biodiversity, economy and travel safety, hunters and scientists say during a conference
"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.

Hunting, visual storytelling and loss: Utqiaġvik photographer speaks at the Arctic at youth panel
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.

Winter Travel, Access and Changing Snow and Ice Conditions
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.

Native knowledge of great lakes ecology: Climate changes to Odawa lands
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.

December was Anchorage’s wettest and second snowiest on record
Climatologist Rick Thoman says climate change is driving this more extreme winter snowfall. As the oceans warm, more moisture evaporates into the air. Then, when the atmospheric conditions are right for a storm, that increased evaporation results in “heavier and heavier precipitation,” Thoman said. That’s in part why Anchorage saw 41.2 inches of snow last month, capping off its wettest year on record, according to the National Weather Service.

In a Tiny Arctic Town, Food Is Getting Harder to Come By
One key species that is being affected by climate change in the tundra is the lemming. Lemmings are small rodents that spend the winter under the snowpack, where it’s warm enough for them to survive and reproduce. The snowpack, in addition to insulating their food, also protects them from predators.
