I suppose I should have included the article in the original post.

No Rise of Airborne Fraction of Carbon Dioxide in Past 150 Years, New
Research Finds
ScienceDaily (Dec. 31, 2009) - Most of the carbon dioxide emitted by human
activity does not remain in the atmosphere, but is instead absorbed by the
oceans and terrestrial ecosystems. In fact, only about 45 percent of emitted
carbon dioxide stays in the atmosphere.

However, some studies have suggested that the ability of oceans and plants
to absorb carbon dioxide recently may have begun to decline and that the
airborne fraction of anthropogenic carbon dioxide emissions is therefore
beginning to increase.

Many climate models also assume that the airborne fraction will increase.
Because understanding of the airborne fraction of carbon dioxide is
important for predicting future climate change, it is essential to have
accurate knowledge of whether that fraction is changing or will change as
emissions increase.

To assess whether the airborne fraction is indeed increasing, Wolfgang Knorr
of the Department of Earth Sciences at the University of Bristol reanalyzed
available atmospheric carbon dioxide and emissions data since 1850 and
considers the uncertainties in the data.

In contradiction to some recent studies, he finds that the airborne fraction
of carbon dioxide has not increased either during the past 150 years or
during the most recent five decades.

The research is published in Geophysical Research Letters.

You along with many other ignorant bloggers and some either ignorant or
malicious news organizations have completely misrepresented the gist of this
research by omitting the critical word "fraction" from your title. When CO2
is released some stays in the atmosphere and some is absorbed by the ocean
and other sinks. All his research says is that the fraction that is absorbed
has stayed constant. In other words, this one analysis indicates that the
oceans have not YET lost their ability to absorb CO2 (albeit at the cost of
ocean acidification). It does NOT mean that the amount of total or
anthropogenic CO2 has remained the same in the air. It is increasing.

See the interview with the author of this paper who says reducing carbon
emissioins is still the only way to head off global warming.

That's almost 1/2 that remains in the atmosphere. And the part that goes
into the oceans is lowering the pH (or increasing the acidity of the
ocean). This is having negative effects on life in the ocean.

Oh, shoot. There you go citing science and not Al Gore.

The Nobel people are going to be very pissed with you. Politicians with
slide shows win over hard science every time.

We are still waiting for the scientific evidence that proves CO2, a gas the
comprise less than one tenth of one percent of our atmosphere, can effect
the average temperature of the earth either up or down.
