Future Arctic winter sea ice is likely to shrink by around 1 million square kilometers (386,000 square miles) more than previously thought, after researchers used clues from a warm period 6,000 years ...

What did the Arctic look like in the distant past? The answer carries significant implications for understanding how it will change in the future in the context of human-driven global warming. Yet ...

Arctic sea ice appeared to be entering a new phase. In the early 2020s, the rapid decline seen over previous decades seemed to ease, leading scientists to ask whether winter sea ice loss had slowed.

The Holocene epoch in the North Atlantic has been characterised by a complex interplay between ocean circulation, cryospheric change and atmospheric variability. Early in the Holocene, meltwater input ...

A new iScience study shows that modern sled dogs and ancient Arctic dogs alike share leg bones about 6% shorter than other canids, a biomechanically advantageous trait that lowers the center of ...

In a new paper, an international team led by scientists from Charles University, Czechia, has brought evidence linking widespread release of methane (CH₄)—a strong greenhouse gas—from the Greenland ...

Arctic sea ice has recorded its smallest winter peak extent since satellite records began 47 years ago, new data reveals. Provisional data from the US National Snow and Ice Data Center (NSIDC) shows ...

A landmark reanalysis of Arctic sediment cores resolves a 50-year taxonomic mystery, revealing that two distinct warm-water ...
