The Baltic Sea is experiencing a reduction in ice due to climate change, with this winter seeing significantly less ice compared to previous years.

Residents wonder if a proposed port expansion will help or hinder efforts to address chronic social problems.

Engineers caution that residents wanting to clear their own roofs face greater risk of hurting themselves or damaging roofs than from a collapse.

In coming decades, the ocean conditions that triggered the snow crab crash and harvest closure are expected to be common.

Atmospheric rivers, those long, powerful streams of moisture in the sky, are becoming more frequent in the Arctic, and they’re helping to drive dramatic shrinking of the Arctic’s sea ice cover.

Backyard Buoys project will give residents real time data such as wave height to whaling crews and communities throughout the North Slope. A system of buoys will be displaced across the slope this summer.

For isolated communities at the top of the world, keeping the planet’s largest land predators -- polar bears -- out of town is key to coexistence.

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.

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 troublesome shipping on the Northern Sea Route continues into the new year. Almost three weeks after the world's most powerful icebreaker arrived in the Chukchi Sea, none of the four vessels stuck in the area have broken out of the ice.

In 2021, the average temperature in Norway was normal, while precipitation was 10 percent below normal. The year is nevertheless marked by great contrasts. The summary of the weather in 2021 was presented at the Meteorological Institute's annual event Climate Status on 5 January. Here you can see video footage of Climate Status (Vimeo)

It has been an Arctic odyssey for the ships and crews that in November got stuck in sea-ice on the remote Northern Sea Route. After a month of icy captivity and subsequent icebreaker rescue, a convoy of nine vessels this week made it to safety in the Kara Sea. On December 7, a Russian nuclear icebreaker completed

Never before at this time of year have so many vessels been rescued out of the ice, says Russia's nuclear icebreaker operator Rosatom. It has been an Arctic odyssey for the ships and crews that in November got stuck in sea-ice on the remote Northern Sea Route.

Majestic, increasingly hungry and at risk of disappearing, the polar bear is dependent on something melting away on our warming planet: sea ice.

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.

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.

Seal meat makes up a good portion of what’s in subsistence hunters’ freezers in Kotzebue. But the sea ice the seals haul out on is diminishing, and new research shows that's shortening the window to hunt seals.

Within a set of glaciers and mountains near Juneau, there’s seismic activity almost every day in the summer. They’re called ice quakes. They’re not as widely understood as earthquakes, but researchers are monitoring them closely.

Ski resorts in Levi, Pallas and Saariselkä kept their slopes open until Mother’s Day this year.

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.
