Atlantic Ocean's Waters Reversed Direction, Study Finds
LiveScience.com ^ | 11/3/10 | Charles Q. Choi

Although it's said that still waters run deep, now scientists find that deep waters aren't still - in fact, the deep waters of the Atlantic Ocean seem to have reversed their direction of flow since the last time ice dominated the Earth.

Instead of heading southward as they do now, these abyssal waters once flowed northward roughly 20,000 years ago, back when the world saw ice sheets more than a mile high, a new study suggests.

The change in flow could have accompanied profound changes in climate, researchers explained.

Climate connection

In the Atlantic, the Gulf Stream brings warm surface water northward from the tropics to high latitudes, where it cools, sinks and flows southward in the deep ocean. The way that water flows in the ocean helps redistribute large amounts of heat - and in this way is critical to how the world's climate works.

The manner in which this Atlantic circulation behaved when global climate was different has proven controversial. Contradictory lines of evidence from during the cold peak of the ice age - the last glacial maximum - make it difficult for scientists to determine whether this ocean circulation was strongly or weakly southward back then.

Now scientists have evidence that such circulation was not only weak, but actually flowed in the opposite direction. The current pattern apparently only arose in the past 10,000 years.

Wow... the Earth and it’s complex interacting systems aren’t static over time.

Who knew?

It’s gotta be Bush / Cheney / Rove / BP / Halliburton’s fault, somehow...

The last similar occurrence was quite awhile ago, long before man and his gas guzzling SUVs ruled the plains

So if we want to effect global climate change, which way do we make the currents flow, and how do we do it?

Yeah sure, let me know when you figure out if that 70’s ice age is still coming or not. If not, I want my money back for the crappy college books I had to buy.

I think their favorite computer model is the one where you feed absolutely ANY data into it and shows it is either caused by or causes global warming.

The old, long-discredited "Hockey Stick" model was pretty good at it. You could feed your grocery list into it and out comes global warming.

and how do we do it?

Build a giant submarine anchored to the seabed and have the propeller push the water the other way??

Let me guess; someone drove an SUV onto the beach it backfired and started the whole thing. /s

Was it 10,000 years ago - or the last time the Sun rose in the West and set in the East?

Silly man, that is at least two generations of model old!

Their newest, and BEST, model is the one where you feed in the causes of Global Warming, and it shows that Global Warming caused the causes!

When you feed in "Climate Science Grant Monies", it shows the data to be both cause AND effect!
