Since you obviously missed the questions in my last post, I’ll repeat them for you –one at a time:
What do you suppose this means: “No RISE of Atmospheric Carbon Dioxide Fraction IN PAST 160 YEARS”
This is'nt some denialist make-up –it's from Dr Wolfgang Knorr at the University of Bristol, and here’s his abstract:
“Several recent studies have highlighted the possibility that the oceans and terrestrial ecosystems have started loosing part of their ability to sequester a large proportion of the anthropogenic CO2 emissions. This is an important claim, because so far only about 40% of those emissions have stayed in the atmosphere, which has prevented additional climate change. This study re-examines the available atmospheric CO2 and emissions data including their uncertainties. It is shown that with those uncertainties, the trend in the airborne fraction since 1850 has been 0.7 ± 1.4% per decade, i.e. close to and not significantly different from zero. The analysis further shows that the statistical model of a constant airborne fraction agrees best with the available data if emissions from land use change are scaled down to 82% or less of their original estimates. Despite the predictions of coupled climate-carbon cycle models, no trend in the airborne fraction can be found.”
It seems to run directly counter to the core AGW argument that the earth’s natural CO2 sinks are weakening—indicating instread, that natural sinks have been expanding as anthropogenic CO2 emissions have increased.
I look forward to your full & thorough rebuttal/explanation —without the cephalopod-esque "flee quickly, expel ink, or use color-changing camouflage" response.
In closing last time you said:
“Those who believe they have credible data and arguments which contradict a relation between anthropogenic CO2 and climate change, ought to formulate it in quantitative terms …”
Seems a bit rich coming from someone who stakes his faith on reports that declare:
“These models DO NOT YET INCLUDE many processes and reservoirs that may be important, such as peat, buried carbon in permafrost soils, wild fires, ocean eddies and the response of marine ecosystems to ocean” [ "may be important"?--what an understatement!]
