New Global Warming Theory

Now this is really cool.

Global atmospheric carbon level may depend primarily on southernmost ocean

“Cold water that wells up regularly from the depths of the Southern Ocean spreads out on the ocean’s surface along both sides of this dividing line, and we have found that the water performs two very different functions depending on which side of the line it flows toward,” said Irina Marinov, the study’s lead author. “While the water north of the line generally spreads nutrients throughout the world’s oceans, the second, southward-flowing stream soaks up carbon dioxide, a greenhouse gas, from the air. Such a sharply-defined difference in function has surprised us. It could mean that a change to one side of the cycle might not affect the other as much as we once suspected.”
