No Rise of Atmospheric Carbon Dioxide Fraction in Past 160 Years(updated 1-1-10)

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.

The anthropogenic CO2 lie by Michael Schmitt

Another domino in the global warming hoax has fallen. "It is shown that with those uncertainties, the trend in the airborne fraction since 1850 has been 0.7 ± 1.4% per decade, i.e. close to and not significantly different from zero." Knorr, W. Is the airborne fraction of anthropogenic CO2 emissions increasing? Geophysical Research Letters, 2009; 36 (21): L21710 DOI: 10.1029/2009GL040613.

This study, the climategate scandal, the contradictions of global cooling claims in the 1980's and the obvious political motivations of global warmers show any reasonable person that there is no global warming or that there are serious doubts about it. And if there is global warming, there should be questions if it is anthropogenic (manmade) and if it is something that is bad for us. This new study shows that it is not caused by anthropogenic CO2 as the global warmers claimed. This manmade CO2 theory was the basis of the entire hoax of manmade global warming.

This will not stop the global warming hoax. There are too many politicians and "climatologists" making billions of dollars off this scam. They belong in jail. They will ignore this study, explain it away, or twist it around. It is irrelevant how much proof you can show, they will insist that their way is right. And they will continue to lie.

The mountain of evidence will continue to grow. Just as "global cooling" was disproved 20 years ago, so shall this be disproving. It is just a question of how much money will be lost in the process. The hundreds of billions of dollars spent will be gone and it could have gone to help feed starving people instead of lining the pockets of greedy and dishonest politicians and climatologists. But then they will find some new scare tactic. They will even try to take credit for preventing global cooling despite the fact they have done nothing in reality. They have already taken credit for stopping global cooling in some articles I read. The contradiction does not even appear to faze them.

Despite their arrogance and audacity, we must fight back with the truth and reveal their true motivations and goals. By exposing their lies, we expose their agenda.
