Earth’s oceans absorbed another record volume of heat in 2025, reinforcing a pattern that climate scientists say is accelerating ice loss in the Arctic and storing energy that will shape weather ...

Arctic sea ice has long been one of the planet’s most sensitive climate barometers, but until now scientists have struggled ...

With the Arctic sea ice maintaining its trend of declining, average extent since the 1980s, there is another side to the story with a unique, slightly more positive statistic. The Arctic sea ice ...

Six projects will investigate innovative approaches that could help slow Arctic sea ice loss and reduce escalating ...

In the middle of the Arctic Ocean, a research ship did something that sounds completely crazy at first. Instead of escaping ...

In the Arctic, there’s a chance that sea ice could disappear in the summer as soon as the 2030s. Already, since the U.S. government started measuring sea ice in 1979, more than 2 million kilometers of ...

Summer sea ice in the Arctic Ocean might be a thing of the past by the 2030s, no matter what we do to curb emissions of the greenhouse gases that cause global warming, an international study released ...

I walked out onto the frozen Arctic water off Utqiagvik, Alaska, for the first time, I was mesmerized by the icescape. Piles of blue and white sea-ice rubble several feet high gave way to flat areas ...

The oldest floating ice in the Arctic appears in red on these maps comparing ice levels in 1985 and this year, from the National Snow and Ice Data Center at the University of Colorado Boulder. Arctic ...

Arctic sea ice helps cool the planet and influences weather patterns around the world, but it is disappearing faster than ever as the climate warms. Scientists have now developed a new forecasting ...

Arctic sea ice reached a record low in March 2025, marking the lowest extent in the 47-year satellite record. The shrinking sea ice, attributed to rising global temperatures from burning fossil fuels, ...
