“We think we may have found the answer. Increased circulation in the Southern Ocean allowed carbon dioxide to leak into the atmosphere, working to warm the planet,” said Princeton University’s Professor Daniel Sigman, co-author of the study.
For years, researchers have known that growth and sinking of phytoplankton pumps carbon dioxide deep into the ocean, a process often referred to as the ‘biological pump.’
“The biological pump is driven mostly by the low latitude ocean but is undone closer to the poles, where carbon dioxide is vented back to the atmosphere by the rapid exposure of deep waters to the surface. The worst offender is the Southern Ocean,” Professor Sigman said. ..."
“This process is allowing some of that deeply stored carbon dioxide to invade back to the atmosphere. We’re essentially punching holes in the membrane of the biological pump,” Professor Sigman said.
The increase in atmospheric carbon dioxide levels over the Holocene worked to counter the tendency for gradual cooling that dominated most previous interglacials.
Thus, the new results suggest that the ocean may have been responsible for the ‘special stability’ of the Holocene climate.
The same processes are at work today: the absorption of carbon by the ocean is slowing the rise in atmospheric carbon dioxide produced by fossil fuel burning, and the upwelling of the Southern Ocean is still allowing some of that carbon dioxide to vent back into the atmosphere.
“If the findings from the Holocene can be used to predict how Southern Ocean upwelling will change in the future, it will improve our ability to forecast changes in atmospheric carbon dioxide and thus in global climate,” Professor Sigman said.

“I ride a bike too. 1300cc “
You are a biker not a cyclist
Kind of blows a huge whole in all this ‘man-made’ hype, huh? /s
Maybe the answer is to put one of them swimming pool covers over the oceans with venting controls.....hope someone gets a big juicy grant to study the feasibility....
