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 Universitys 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. Were 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.

There is a reason for it. If they want to sound credible they must explain how the ice ages ended. And if they want to sound consistent it has to be blamed on CO2. There's no other way. That's their whole premise. So how do you explain CO2 in an era before before fossil fuels ? Blame some BS phenomena that happened hundreds or thousands of years ago in an obscure ocean in a far corner of the world and which can never be proved.
You mean it wasn’t the SUV’s or cow farts? /s
Somewhere, some global warming, freaked out Democrat, social justice warrior, is having a cow, and dreaming up ways to blame Trump for it. What a bunch of asshats.
We actually have a long way to warm up before we reach “historic” temperatures. And it is all Antarctica’s fault.
Before Antarctica broke free from South America, you didn’t have polar water currents that fueled polar air currents. Once it was free, those polar currents formed and caused a place akin to modern Alaska to grow colder and grow miles thick ice sheets. This pulled the PLANET’s temperature down 10°F at least.
Before that, there were only tropical and semi-tropical climate systems on the planet barring deserts and swamps. There was no tundra or taiga. Ice ages probably occurred but were just spring-like versus freezing.
We’ll know we’ve warmed to historic norms when there is no ice at the south pole, just like it was when the dinosaurs ran around.
The breakup of the pre-Pangea supercontinent Rhodinia is believed responsible for the end of “Snowball Earth” and the subsequent “”Cambrian Explosion”, the sudden appearance of more varied and complex life forms.
so, nothing we did or could hope to do.
I demand Gondwanaland reunification!
Thanks ETL. And no thanks. This is just AGW BS.

All those SUVs... idling under water for 11,000 years...
A leak?....the gestimating and assumptions and computer models are all over the place...the Earth will do exactly as it pleases . Our existence is a mere hiccup to this fantastic creation of God’s ...I wish those who do such study and observations of our planet would just say that they think (guess) this is how it works...the arrogance of some of these hired scientists is only surpassed by their ignorance at times.
Mama’s been fartin’ for ELEVEN THOUSAND YEARS !!!! ???
What about carbon credits
I’d have more credibility in his findings if he had said that “fairy dust” combined with the CO2 had warmed us for 11,000 years.
The total amount of CO2 in the earth’s atmosphere today is something like a measly 0.038%. And that includes the NATURALLY occuring variety. Moreover, the single most powerful gas in the greenhouse system, by far, is water vapor, nearly all of which is of natural origins. Something like 97% of the GH effect on earth is due to water vapor.
True CO2 is not the driver of of the warming and cooling we've been seeing but it does crate some warming very little.
If the CO2 in our atmosphere doubled the CO2 alone would create approximately 0.6 Deg C warming. To return back to glaciation we would have to drop in temperature about 10 deg C.
There isn't that much CO2 in our atmosphere to create that much warming. Which means this CO2 alone isn't what is creating our present interglacial period.
