"No Rise of Atmospheric Carbon Dioxide Fraction in Past 160 Years"

Science Daily reports that a new study by 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" and finds that there has been no increase in the fraction of airborne carbon dioxide in the past 160 years.

Knorr's research was published November 7, 2009 in Geophysical Research Letters.

I have no reason to conclude that Knorr is trying to debunk global warming. But it's nice to know that there are still scientists who revisit the data and challenge aspects of prevailing theories. (I suspect more and more that it's journalists and politicians who are pushing the notion that these issues are settled.)
