For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages. Now, a new study published in Science Advances challenges this idea ...

Sea ice is frozen ocean water that melts each summer, then refreezes each winter. The Arctic is warming more than twice as fast as the rest of the planet.

The Arctic Ocean will be ice-free in the summer within the next 30 years, ... Sea ice is frozen ocean water that melts each summer, then refreezes each winter.

Scientists believe the Arctic sea ice, or the floating ice cover of the Arctic Ocean, has reached its minimum extent for the year, shrinking to the second lowest extent since record-keeping began ...

With the setting of the sun and the onset of polar darkness, the Arctic Ocean would normally be crusted with sea ice along the Siberian coast by now. But this year, the water is still open. I’ve ...

According to Cai, in the 1980s and 1990s, carbon dioxide levels were lower in the Arctic Ocean and it was understood that ice melt was happening more in the Marginal Sea basin, and it advanced ...

From more frequent wildfires to rising sea levels, climate change is disrupting ecosystems and upending once-stable weather ...

Researchers are warning that Arctic Ocean sea ice is melting at an even faster pace than previously thought — and the region could experience its first ice-free conditions sometime before the 2030s.

For that reason, changes in sea ice cover have a big impact on how much sunlight the planet absorbs, and how fast it warms up. Each year a thin layer of the Arctic Ocean freezes over, forming sea ice.

Weakening of Cold Halocline Layer Exposes Sea Ice to Oceanic Heat in the Eastern Arctic Ocean. Journal of Climate , 2020; 33 (18): 8107 DOI: 10.1175/JCLI-D-19-0976.1 Cite This Page : ...

Evidence for an increasing role of ocean heat in Arctic winter sea ice growth. Journal of Climate, 2021; 1 DOI: 10.1175/JCLI-D-20-0848.1; ...

For comparison, recent years have seen the Arctic Ocean with a minimum sea ice cover in September of around 1,274,000 square miles, which is about a third of the area of the US.
