Study: Past Climate Change Was Caused by Ocean, Not Just the Atmosphere

Chipmunk100 writes Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. Researchers have found that circulation of the ocean plays an equally important role in regulating the earth's climate. The study results were published the journal Science (abstract. "Our study suggests that changes in the storage of heat in the deep ocean could be as important to climate change as other hypotheses – tectonic activity or a drop in the carbon dioxide level – and likely led to one of the major climate transitions of the past 30 million years," said one of the authors."

    I know you're kidding around, but make sure that you know the KKK was run as a militant arm of the Democrat party to run Republicans out of town.

    The year is 2014, and these "scientists" are just NOW realizing that the ocean plays a key role in global climate change?

    No, the slashdot summary paints a binary picture of air/water, to say that such a naive picture would find itself in one of the world's most respected scientific journals stretches credulity well past it's breaking point.

    BTW: El-Nino is caused by oscillating prevailing winds pushing warm water east or west, it acts like a "see-saw" in a strong wind, however you're correct in that the imbalance does "pump" some deep water to the surface. I haven't RTFA but what they are more likely talking about here is the The Great Ocean Conveyor Belt and the effect on prehistoric climate when those currents abruptly changed for some geological reason (such as a gazzillion tons of ice falling off greenland, tectonic movements, etc).

    The facts that the Republicans used to be the liberal party, and the Democratic Party, the conservative ones. But in the past 150 years or so, the parties swapped, they might as well have renamed themselves a few times in there. In the first 100 years of the USA, the parties changed names more often, but didn't after.

    Doesn't help that the mainstream politicians are always left of the southern standard. David Duke was a "local" Democrat, but when going national, he changed parties to the one that's more conservative. A Southern Democrat is right of a northern Republican. So dividing on party lines for such things is useless.
