Despite global warming, Antarctica’s sea ice is growing

antarctica sea iceThe Antarctic Ocean has remained unchanged by global warming due to the Deep Ocean water that is constantly pulled to the surface in a centuries-long pas de deux, a new study has found. The University of Washington and the Massachusetts Institute of Technology’s latest research discovered that ocean currents and strong winds keep the seawater around Antarctica at nearly the same temperature, despite some warming in other bodies of seawater.

Climate models and satellite imagery show that the unique currents around Antarctica are constantly pulling seawater up to the surface, which last touched the Earth’s atmosphere before the Industrial Revolution. The paper was published online May 30 in the journal Science Direct in Remote Sensing of Environment.

It shows gale-force westerly winds are constantly whipping around Antarctica and pushing surface water north, continuously drawing up water from far below. The Southern Ocean’s water comes from such great depths, and from sources that are so deep, that it takes centuries before the water reaches the surface and interacts with the atmosphere. Even if it does, the average temperature above the Southern Ocean is so cold that its impact is insignificant.

“With rising carbon dioxide you would expect more warming at both poles, but we only see it at one of the poles, so something else must be going on,” said lead author Kyle Armour, a UW assistant professor of oceanography and of atmospheric sciences. “We show that it’s for really simple reasons, and ocean currents are the hero here.”

    Blinkin’ heck that picture looks cold!

    As for “something else must be going on” – Look anywhere else, [i]everywhere[/i] else, but never ever inward at the meme. No sirree, we can’t have that.

    It amazes me how grimly some people will cling to an idea and never admit to being wrong. It’s as though they believe that being wrong is some kind of sin rather than evidence that one has grown up and matured.

    Either that or they’ve been bought outright.

    A.D. Everand They created a $$Trillion industry on nothing but hot air and complete BS knowing what they were doing . They aren’t about to apologise for the scam or the stupidity of others . That’s their living and ego’s wrapped into this fraud . As long as someone is buying they are selling it .
    It’ s just business, a crooked one but people buy junk they don’t need every day .
    Tax payers have been ripped off and industries devastated by the scam . The inconvenient truth disappeared long ago . No apologise expected … jail time yes .

    Hi Amber. Oh yes, I know that, I’ve been watching this for some years now. They’ve been bought outright, like I said. It still amazes me (I know it shouldn’t).

    I’m watching for the endgame now. Got the popcorn in. 😀

    Hi A. D. ,
    I believe you are right as the ship goes down the louder they will yell .
    Two legged stools tend to fall over and the “businesses” that received $ Billions of tax payer funding (the third leg ) are continuing to go bankrupt . Citizens in countries who have been sold out by politicians have had enough of the stop the planets fever BS and being ripped off in their energy bills.The subsidy game is unwinding too . Well except maybe in Ontario which is the poster boy of some of the dumbest ecovangilists on the planet .

    Despite their efforts to silence ,intimidate and lie their way further the engines have been cut on one of the biggest scams in history . It will drift on a while longer .

    What is truly amazing is that even with $$Billions of free media propaganda pushing the scam it took on water .

    Who ever invented the internet thanks .
