Published Research Paper Finds No Rise in Fraction of Atmospheric CO2 in Past 160 Years!
Like I keep saying, the Earth continually re-absorbs CO2 and it isn’t going to stop anytime soon:
No Rise of Atmospheric Carbon Dioxide Fraction in Past 160 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.

I have been trying to figure out this climate change story for ages, I can see some gaping holes in the official story but for most of it I do not have the scientific background. The one thing I do know is that in the 50′s there were not only the gasworks but most houses used coal for heating. All this soot that came out of the chimneys did not go up into the atmosphere but came down, the front of most buildings were soot stained, at the end of the day the inside of my shirt collar would be black.
Everybody knows enough about physics that they know if something is lighter than the medium into which it is released it rises. If it is heavier it sinks. So a helium balloon, which is lighter than air goes up, a brick which is heavier than water sinks.
Weight of CO2: 1.97 grams per liter
Weight of air: 1.2 grams per liter
