Archived’ heat trapped below the surface of the Arctic has the potential to melt the entire region’s sea ice, scientists warn.
-
The study, published in the journal Science Advances, shows that Arctic sea ice is not just threatened by the melting of ice around its edges.
-
Warmer water that originated hundreds of miles away has penetrated deep into the interior of the Arctic, researchers found.

-
The upper ocean in the Canadian Basin has seen a two-fold increase in heat content over the past 30 years.
-
They traced the source to waters hundreds of miles to the south, where reduced sea ice has left the surface ocean more exposed to summer solar warming.
-
In turn, Arctic winds are driving the warmer water north, but below the surface waters.
-
This means the effects of sea-ice loss are not limited to the ice-free regions themselves, but also lead to increased heat accumulation in the interior of the Arctic Ocean that can have climate effects well beyond the summer season.
