North Pole soon to be ice free in summer

The Arctic Ocean in summer will very likely be ice free before 2050, at least temporarily. The efficacy of climate-protection measures will determine how often and for how long. These are the results of a new research study ...

Increasingly mobile sea ice risks polluting Arctic neighbors

The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil, according to new research from CU Boulder.

Video: Operation IceBridge completes 11 years of polar surveys

For eleven years from 2009 to 2019, the planes of NASA's Operation IceBridge flew above the Arctic, Antarctic and Alaska, gathering data on the height, depth, thickness, flow and change of sea ice, glaciers and ice sheets.

Researchers find new reason Arctic is warming so fast

The Arctic has experienced the warming effects of global climate change faster than any other region on the planet. Scientists at the Scripps Institution of Oceanography have developed a new theory aided by computer simulations ...

NRL researchers monitor changing Arctic using sound

U.S. Naval Research Laboratory scientists developed Ice-tethered Acoustic Buoys to monitor the acoustic and oceanographic environment in the changing Arctic. The buoys provide critical oceanographic data to improve prediction ...

A relationship between severe winter weather and Arctic warmth?

A new review article published in Nature Climate Change evaluates whether severe winter weather in the United States, Europe and Asia is sensitive to Arctic temperatures. The lead author is NSF-funded scientist Judah Cohen, ...

Meet the narwhal, 'unicorn of the sea'

Narwhals are often called the unicorns of the sea. The long tusk of the male narwhal sets these whales apart, but it's not the only thing that makes Monodon monoceros among the most intriguing and mysterious marine mammals.

Cracks in Arctic sea ice turn low clouds on and off

The prevailing view has been that more leads are associated with more low-level clouds during winter. But University of Utah atmospheric scientists noticed something strange in their study of these leads: when lead occurrence ...

Sea-ice-free Arctic makes permafrost vulnerable to thawing

Permafrost is ground that remains frozen throughout the year; it covers nearly a quarter of Northern Hemisphere land. The frozen state of permafrost enables it to store large amounts of carbon; about twice as much as in the ...
