For those not familiar with Science Daily, it is a decidedly leftwing website. But even with the spin they put on things, it has a few interesting posts today.
The earth's ability to sequester Carbon Dioxide is not changing as many had claimed.
Can Carbon Dioxide be at Good Thing?
I am not sure why this is such a new "revelation" or an "unexpected benefit" as the article claims.
The earth's ability to sequester Carbon Dioxide is not changing as many had claimed.
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. . . .
