Carbon Dioxide ‘Leak’ in Southern Ocean May Have Warmed Earth for 11,000 Years
Sci-News ^ | Aug 1, 2018 | News Staff / Source

“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.

The Earth’s oceans lock away atmospheric carbon dioxide, but a ‘leak’ in the Southern Ocean, which surrounds Antarctica, brings the greenhouse gas back into the atmosphere.

A team of scientists led by Princeton University and the Max Planck Institute for Chemistry looked at concentrations of nitrogen embedded in deep-sea corals and shelled microorganisms called diatoms and foraminifers to identify an increase in Southern Ocean upwelling during the past 11,000 years, which could explain the mysterious warmth of the Holocene period that allowed human populations to flourish.

Note how they’re saying the climate is stable.
Yet they claim it isn’t and we must embrace communism to save the earth any other time.
Seems they want it both ways.

Just recently it was announced that at least one (and,IIRC,it was more than one) active volcano was discovered under the Antarctic ice shelf and that it's believed that volcanic activity is at least partially responsible for the melting of that ice shelf.

And yet I'm forced to ride a bike in order to lower CO2 in the atmosphere.

CO2 is life.

Life is what they are trying to stomp out.

“The biological pump, in its simplest form, is the ocean’s biologically driven sequestration of carbon from the atmosphere to deep sea water and sediment.[1]

It is the part of the oceanic carbon cycle responsible for the cycling of organic matter formed mainly by phytoplankton during photosynthesis (soft-tissue pump), as well as the cycling of calcium carbonate (CaCO3) formed into shells by certain organisms such as plankton and mollusks (carbonate pump).[2]

Overview:

The biological pump can be divided into three distinct phases,[3] the first of which is the production of fixed carbon by planktonic phototrophs in the euphotic (sunlit) surface region of the ocean.

In these surface waters, phytoplankton use carbon dioxide (CO2), nitrogen (N), phosphorus (P), and other trace elements (barium, iron, zinc, etc.) during photosynthesis to make carbohydrates, lipids, and proteins. Some plankton, (e.g. coccolithophores and foraminifera) combine calcium (Ca) and dissolved carbonates (carbonic acid and bicarbonate) to form a calcium carbonate (CaCO3) protective coating.

Once this carbon is fixed into soft or hard tissue, the organisms either stay in the euphotic zone to be recycled as part of the regenerative nutrient cycle or once they die, continue to the second phase of the biological pump and begin to sink to the ocean floor.

The sinking particles will often form aggregates as they sink, greatly increasing the sinking rate. It is this aggregation that gives particles a better chance of escaping predation and decomposition in the water column and eventually make it to the sea floor.

The fixed carbon that is either decomposed by bacteria on the way down or once on the sea floor then enters the final phase of the pump and is remineralized to be used again in primary production.

The particles that escape these processes entirely are sequestered in the sediment and may remain there for millions of years.

It is this sequestered carbon that is responsible for ultimately lowering atmospheric CO2. ...”

CO2 does not cause warming...or cooling...C02 IN the atmosphere FOLLOWS warming or cooling.

So glad we have all the right answers now.

That is precisely what the Vostock ice core evidence shows. That CO2 rises actually lags behind temperature rises, by something like 800 years on average, if I recall correctly.

Temperature and CO2 levels do not coincide.

Historically, CO2 increases lag behind temperature increases

These tards won’t let go of the greenhouse gas theory.

Well that can't be right. The upwelling warm water caused increases in atmospheric CO2? And then the abundant CO2 caused land-based plants to flourish, enabling agriculture and causing much better conditions for human?

Can't be so at all. CO2 and warmth is supposed to be

DOOM.

Don't those scientists know that's the consensus?

Nothing so practical as a plug. But they do want money, to pay for more regulations to clamp down on people.
