Arctic sea ice isn't just threatened by the melting of ice around its edges, a new study has found: Warmer water that originated hundreds of miles away has penetrated deep into the interior of the Arctic.

That "archived" , currently trapped below the surface, has the potential to melt the region's entire sea-ice pack if it reaches the surface, researchers say.

The study appears online Aug. 29 in the journal Science Advances.

"We document a striking warming in one of the main basins of the interior Arctic Ocean, the Canadian Basin," said lead author Mary-Louise Timmermans, a professor of geology and geophysics at Yale University.

The upper ocean in the Canadian Basin has seen a two-fold increase in heat content over the past 30 years, the researchers said. 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 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," Timmermans said. "Presently this heat is trapped below the surface layer. Should it be mixed up to the , there is enough heat to entirely melt the sea-ice pack that covers this region for most of the year."

It looks like we have a new metric to watch for global warming's progress.

Oh... look Ma... there is another one of them there climate deniers eatin crow! Eeewwwhhhh,

Aren't the denialists still claiming that the world is cooling?

LOL!

Nice copy/paste, grandpa. How many articles will you post that same thing on? With no thought or research involved the sky is the proverbial limit, eh?

I've booked my cruise for next year because if I wait much longer it won't be here. Glad I went to the Antarctic last year.

The "Holier than Thou" Chicken Little Jackass brays.
Tell us jackass, do you even give the minutest thought to all the CO2 being spewed, when you go on these WASTEFUL jaunts. Of course NOT, but keep braying at the heretics, you'll save the world.

Only in AGW Cult Pathological "science", hot water sinks.

Denialism has sunk to a new low when it tries to deny basic physics, chemistry, and oceanography. Not all ocean water has the same salinity. https://www.scien...salinity Salinity has a dramatic effect on density. https://scienceof...ylor.png Water at 40 ppt salinity and 13 deg C, for example, will be denser than and thus lie under water at 32 ppt salinity and 0 deg C.

Another Chicken Little jackass brays.
AGW jackass-ism has risen to a new height.
This jackass "knows" the basic physics....and... HAWW...HEE...HAWW...HEE, that's why the ocean water heated in the tropics, sink, then travel north, before magically coming to the surface to release its heat....oh wait....it does not sink.
Keep braying jackass.

Yes, you can't be bothered to think about fluid dynamics beyond the ice melting in your highball glass.

anti has run out of arguments, it's all the same "Chicken little! Jackass! ... HAWW...HEE...HAWW...HEE" from him the last while. The cognitive dissonance is ringing louder and louder so he has to bray louder and louder. So sad.

Anyway, back to realty.

That warm water is going to mix and the ice is going to melt, just a matter of time. I wonder if we will see it happen?
