No rise of airborne fraction of CO2

Science Daily reports, “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.”

SD says, however, that “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”.

But in contradiction to those studies, Wolfgang Knorr of the Department of Earth Sciences at the University of Bristol analysed afresh available data and found that “carbon dioxide has not increased either during the past 150 years or during the most recent five decades.”
