Atlantic Ocean's Waters Reversed Direction, Study Finds
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.

STOP swimming in the atlantic ocean, you are fucking with the currents and bringing catastrophic climate change to our planet!!!!!
