OK.
I don't have the answer. I'm not a climatolagist with all the intellect and answers, and i don't understand your maths (didn't understand your first post, mathematically). How can your calculations assume 0% absorbtion? There is absorbtion, so how do you cancel it out? I don't mean to be rude, but if one mathematician with one point of order isn't enough to sway the bulk of scientific opinion then it won't sway me. If you can, take your idea to the scientific community and dumfound them and I will be intruiged.
What about this?
Southern Ocean already losing ability to absorb CO<SUB>2</SUB> - earth - 17 May 2007 - New Scientist Environment

Corinne Le Quéré at the University of East Anglia in the UK, and colleagues say their study suggests that climate feedback loops – whereby more CO2 in the atmosphere causes warming which in turn releases even more CO2 from the oceans – are happening between 20 and 40 years before they were expected.

As the atmosphere warms due to the buildup of greenhouse gases, it transfers some of this heat to the ocean, slowing the pace of climate change.

Of the new carbon released to the atmosphere from fossil fuel combustion and deforestation, some remains in the atmosphere, while some is taken up into the land biosphere (in places other than those which are being cut) and into the ocean. The natural uptake has been taking up more than half of the carbon emission. If changing climate were to cause the natural world to slow down its carbon uptake, or even begin to release carbon, that would exacerbate the climate forcing from fossil fuels: a positive feedback.
...
They find that the Southern Ocean has begun to release carbon since about 1990, in contrast to the model predictions that Southern Ocean carbon uptake should be increasing because of the Henry's Law thing. We have to keep in mind that it is a tricky business to invert the atmospheric CO2 concentration to get sources and sinks. The history of this type of study tells us to wait for independent replication before taking this result to the bank.

The whole article is good. Not irrefutable yet, but they're checking it out.
So the ocean sucks it up, kills off a bunch of life (if too much is sucked up), lets it back out again, but can't suck up as much next time as the acidification has already begun - which kills the nutrients that would absorb the co2. Same for the forests that we see in that "breathing Earth" graph in Al Gore's documentary and everywhere else. This gets progressively worse over time. Leaving more and more co2 in the atmosphere than before.
If it isn't being safely absorbed - it is being released. Forests, oceans, wetlands, permafrost absorb, hold and release according to a natural cycle - unless destroyed. Man has elevated levels AND reduced Earth's capacity to cope with even it's regular releases (excluding direct man-made emissions).
In a few months, i expect, this angle of skeptic attack will be widely debunked also (I would be suprised if it hasn't already been - i just can't find it - maybe i need to contact my local university). I can only go off the literature that is available at the time and this is the first time i have seen anyone use the Earths "mysterious
extra" emissions (using their own calculations i might add.. which i cannot possibly refute as i don't even understand them) to cast doubt. Are you the only person who thinks this proves that man isn't to blame? Any climatologists support you?
I won't respond to all your other stuff as we have deviated from your original assertion. Feel free to ask them elsewhere. Start a thread about feedback loops and we can talk about them there.
I've got tons more to learn, i appreciate this topic.
