It's no mystery why carbon dioxide (CO2) levels fluctuate with the seasons: As greenery grows in the spring and summer, it soaks up the planet - warming gas, and when trees shed their leaves in the autumn, some of that gas returns to the atmosphere.

By accounting for both CO2 and oxygen levels in the atmosphere, scientists have calculated that oceans and plants each absorb roughly one - quarter of humanity's CO2 emissions, leaving half to build up in the atmosphere.

Instead of piping in natural CO2, it will use the greenhouse gas captured at a coal - fired power plant just completed nearly 100 miles north of here and send it down into the reservoir, pushing oil out and leaving the greenhouse gas deep below, safely locked away from the atmosphere, so it does not add to global warming.

So what we might like as the effect in a beer or wine is a waste product from the organisms that are excreting this, and those yeast took in Dave as a [n] atom of carbon in a maltose sugar molecule that the brewmeister made — it's part of the beer - making process — and I tracked this back in a few paragraphs to being in the grain of the barley plant, in the starch of a barley plant and then coming from the atmosphere as a CO2 molecule that entered the leaf of the barley plant.

They used three runs: a control run with CO2 at the leaf level and in the atmosphere, a run where only the vegetation responds to a rise in CO2, and a run where only the atmosphere responds to the CO2 increase.

The finding that a significant portion of CO2 can take thousands of years leave the atmosphere makes the case for developing CDR solutions all the more imperative.

One thing that always seems to be left out of attempts to give clarity to the subject is the fact that it is CO2 in the atmosphere that makes Earth a habitable planet, well one of the things.

It is the reduced amount of radiation leaving the top of the atmosphere that changes the earth's balance of heat, and therefore defines the «direct radiative forcing» caused by doubling CO2.

Today, as we pump more CO2 into the atmosphere, slightly more flows from the atmosphere into the ocean, leaving enough to increase the atmospheric CO2 concentration, and increasing the oceans carbon content.

Because CO2 makes the atmosphere more opaque to infrared radiation, and because the atmosphere gets colder as you get higher, the «effective radiation temperature» of the infrared radiation leaving the earth is made colder by increasing CO2 (fewer Watts per square meter of infrared radiation leave the top of the atmosphere).

There is CO2 continually leaving the ocean and entering the atmosphere in places where ocean upwelling brings carbon - rich waters to the surface.

Kim, for this to be the case, ocean acidity would have to be decreasing as CO2 leaves the water to enter the atmosphere.

Because the CO2 is «seeking» equilibrium, half is left in the atmosphere whether the amount added to the atmosphere is a large or small amount.

Not only do we know how much CO2 we emitted (more than is now left in the atmosphere — which means that the natural reservoirs have taken up part of our CO2 emissions, rather than having released CO2 in response to a climate change).

There are two possible places to cap carbon: (1) where CO2 leaves the economy and enters the atmosphere, and (2) where carbon enters the economy in the form of a fossil fuel.

3) Some recent research indicates that enhanced CO2 availability increase the efficiency of water use by trees, because it's easier to pull sufficient amounts of the gas from the atmosphere without having to leave their stomata open and let water escape.

Global warming is expected to reduce the ocean's ability to absorb CO2, leaving more in the atmosphere... which will lead to even higher temperatures as below from NASA.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

But if we fail to reduce at the required rate — and the inadequate emissions targets indicate this is the intention — then we will be left with no option but to scrub the excess CO2 back out of the atmosphere in future.

3 claims that the GHG human emission rate is approximately 2 times larger than the observed rate during the last decades, so if the Sun drives a little bit the CO2 and CH4 cycle mechanisms (which in this case are absorbing large amount of CO2 and CH4 from the atmosphere) it might leave a signal in the CO2 and CH4 record as well.

But also, it absorbs CO2 from the atmosphere, via its leaves, and by the process of photosynthesis converts that to organic (carbon based) compounds.

If they can not provide a verifiable experiment regarding the present amount of CO2 in the atmosphere and how it effects the climate and creates their anthropogenic global warming, then believing that it does so is akin to believing that Santa Clause is real and you need to be good to get something left under the tree.

This leaves around 3 or 4 billion tonnes that are somehow being absorbed by the oceans, the land biosphere, or both.One possibility is that most of the man - made CO2 which does not accumulate in the atmosphere is being absorbed by the oceans... This view is supported by indirect evidence derived from the atmospheric nuclear bomb tests of the 1950s and 1960s.

It may be that CO2 is still the main problem, or it may be high atmosphere water vapour left by planes, or it might just be natural after all.

But the spike for CO2 on the left dwarfs all the other greenhouse gases, and tells us something very important: most of the energy being trapped in the atmosphere corresponds exactly to the wavelength of energy captured by CO2.

On that basis CO2 can add a million times as much heat as is required to remove it if you leave it in the atmosphere long enough.

In the upper layers of the atmosphere the band initially gets narrower and then splits into several narrow bands (the roto - vibrational spectrum) leaving more room for the increase in CO2 concentration being more effective.

If you were to produce a chaotic model using the above, I would venture a prediction that the above former were the massive attractors about which we could make some decent predictions about the future but that the latter human produced CO2 inserted into our atmosphere would leave us with hopelessly inadequate and wrong predictions because CO2 contributed by man is not an attractor of any significance in the chaotic Earth climate system nor is CO2 produced by man a perturbation that would yield any predictive ability.

Nearly 1/3 of the 8 GtC / year is absorbed by just forests worldwide currently http://www.csiro.au/news/Forests-absorb-one-third-our-fossil-fuel-emissions.html Which leaves a miserly 1.333 GtC / year for the rest of the biological sinks (and oceans) to absorb leaving the atmosphere CO2 at 4 GtC / year increase = the CO2 levels are still to low and this shows the CO2 global pathway as definitely unknown.

Thus even if more C4 plants are grown, that changes the amounts of 12CO2 which is absorbed vs. 13CO2, but as long as the O2 levels show that the biosphere is a net sink for CO2 (whatever the type), more 12CO2 leaves the atmosphere than 13CO2, compared to the atmospheric isotope ratio.

It also ignores a further positive feedback whose occurrence is widely predicted, namely the Ocean Heating & Acidification causing the decline of the oceans» carbon sink, thus leaving more of annual anthro - CO2 emissions in the atmosphere, thus adding to ocean heating.

The space left in the atmosphere for storing CO2 is the ultimate scarce resource, and it needs to be priced accordingly.»

That shows that the biosphere is a net source of oxygen, thus more CO2 uptake than decay (the «greening earth»), preferably more 12CO2, thus leaving more 13CO2 in the atmosphere.

Exactly where the CO2 is going, when it leaves the atmosphere is another issue.
