The ocean's biological pump works to draw down atmospheric carbon dioxide (CO2) by exporting carbon from the surface ocean.

The earlier benchmark happens because the biosphere draws down only a certain amount of carbon dioxide each growing season, leaving behind excess CO2 that hangs around into next year.

Since there is much more land and vegetation north of the equator, it is there that CO2 concentrations fall for a few months, as plants draw it down from the atmosphere.

Reforestation and increase of soil carbon can help draw down atmospheric CO2.

I do believe that research has shown that sequestration of CO2 in soils and biomass through organic agriculture (including the use of biochar) and reforestation (which must of course begin with ending deforestation) can draw down the already dangerous anthropogenic excess of CO2 and I think it is urgent that we start doing that — it's as urgent as ending CO2 emissions as rapidly as possible.

That solution is to rapidly phase out fossil fuels and replace them with non-carbon sources of energy, use that energy with maximum efficiency, and use organic agriculture and reforestation to to draw down the already dangerous anthropogenic excess of atmospheric CO2.

And eventually as the far more massive ocean cooled it would be able to hold more dissolved CO2, so atmospheric CO2 would be drawn down, thus reducing the greenhouse effect further (even more energy out).

We still need to end ALL anthropogenic GHG emissions as soon as possible — AND we need to beging drawing down the excess CO2 that we have already put into the atmosphere.

The existing anthropogenic excess of atmospheric CO2 is self - evidently already causing dangerous warming so we do need to draw it down to preindustrial levels as quickly as possible.

All of this is reason for everyone and his brother, aunt and sister to greatly reduce their own GHG emissions, and to scream bloody murder till every corporation, institution and governmental body they have any influence over to immediately institute policies to rapidly bring down GHG emissions and look at reliable ways of drawing down atmospheric CO2 levels directly (especially replanting grasslands in the north, tree planting toward the equator where albedo change is not an issue).

They have ranged from seeding the oceans with iron filings to draw down atmospheric CO2, to the launching of billions of aluminised balloons to reflect the sun's rays away from the Earth, to the installation of giant mirrors in space that intercept those rays before they reach us.

Circulation would bring fresh CO2 from elsewhere to replenish what had been drawn down over Antarctica.

Draw down of CO2 plus active geo - engineering to hold the permafrost and its methane stores — and that's not even considering the need to halt falling albedo.

And then it cooled again right after that anyway — again without a concomitant «amplifying - the - cooling» draw - down in CO2 concentration.

Fourth, steps must be taken to «draw down» atmospheric CO2 via improved farming and forestry practices, including burning of biofuels in power plants with CO2 sequestration.

CO2 could be removed by using the draw - down from such methanogens, especially if they are supplied with carboxysomes (via GE).

We need to rapidly transition to a zero carbon economy, and draw down billions of tonnes of CO2 from the atmosphere, so it makes no sense for the SA government to allow any new projects that put us at greater climate risk, particularly in sectors where climate - safe alternatives are readily available.

We need to rapidly transition to a zero carbon economy, and draw down billions of tonnes of CO2 from the atmosphere in order to restore a climate that is safe for all people, species, and ecosystems.

Burning sustainably designed biofuels in power plants, with the CO2 captured and sequestered, would also help draw down atmospheric CO2.

Actually my guess would be that by 2075 new technologies like inertial confinement fusion will have decreased CO2 emissions to the point where nature is drawing down more than we emit, so that CO2 will decrease for a while, starting well before 2100.

We then define our assumptions about the potential for drawing down atmospheric CO2 via reforestation and increase of soil carbon, and we define fossil fuel emission reduction scenarios that we employ in our study.

Reforestation and increase of soil carbon can help draw down atmospheric CO2.

Ergo, it is simply wrong to assume that any excess draw down of CO2 due to the CO2 fertilization effect will not only be matched, but exceeded by an increased production of CO2 by cellular respiration.

The «draw down» may be achieved by using that percentage of carbon from an atmospheric source such as agricultural waste, deliberate agriculture (e.g. azollaculture), or artificial photosynthesis via, for instance, using solar energy to hydrolyze water, and combining the hydrogen with CO2 from the air to produce fuel.

Of course, using CO2 dragged from the atmosphere will, in turn, drive R&D for carbon capture of various types, which will end, IMO, in drawing down atmospheric CO2 to pre-industrial levels.

Because of that, in any healthy plant over the course of a year, it draws down far more CO2 through photosynthesis then it produces by oxidizing sugars.

New methods of grazing, called Adaptive Multi-Paddock (AMP) grazing, are showing great promise in regenerating soils — and regenerated soils draw down enormous amounts of CO2 from the atmosphere.

The past 150 million years has seen a steady drawing down of CO2 from the atmosphere.

It could also have increased the rate of weathering and helped to draw down atmospheric CO2.

However, equilibriating the deep ocean will only draw CO2 concentrations down to 25 - 30 % of total emissions (Archer), or to 45 to 55 % of the net increase to a given date.

In that case it would just be feasible to get atmospheric CO2 back beneath 350 ppm via the carbon uptake potential of improved forestry and agricultural practices, which could draw down atmospheric CO2 by as much as about 50 ppm.

Perhaps it draws it down but the CO2 outgassing from warming oceans eventually starts to catch up — after 800 years.

And if we don't take urgent action NOW to quickly end our GHG emissions and draw down the already dangerous anthropogenic excess CO2, then AGW is likely to have horrific effects on the entire biosphere that will go far beyond merely ending human civilization.
