I am afraid that is just sloppy journalism Pat. :-S

According to (another Pat?) Pat Michaels at World Climate Report:

“Dr. Knorr carefully analyzed the record of anthropogenic CO2 emissions, atmospheric CO2 concentrations, and anthropogenic land-use changes for the past 150 years. Keeping in mind the various sources of potential errors inherent in these data, he developed several different possible solutions to fitting a trend to the airborne fraction of anthropogenic carbon dioxide emissions. In all cases, he found no significant trend (at the 95% significance level) in airborne fraction since 1850.

(Note: It is not that the total atmospheric burden of CO2 has not been increasing over time, but that of the total CO2 released into the atmosphere each year by human activities, about 45% remains in the atmosphere while the other 55% is taken up by various natural processes—and these percentages have not changed during the past 150 years)“

Here’s a link to the original paper hosted by another site

Rezwan thinks it sweet that I still believe in an evidenced based outcome to the (still very much alive) GW debate.
Sweet though I undoubtedly am :), if there is any chance of the truth prevailing then, when we are presented with a piece of actual science, we must read what is there rather than what we want to see.
