@Foxfyre,
Foxfyre, my models are arbitrary.
I claim my models are no more arbitrary than those presented by IPCC. In the case of my model below, I have made the percentage of AAGT caused by SI = 99.0%, the percentage of AAGT caused by CAD = 0.9%, and the percentage of AAGT caused by MAF = 0.1%, totalling 100% (Please see below my definitions of SI, CAD and MAF in my Model II).
By posting arbitrary models, I think those who would rebut my models, should provide alternate models: models of their own or models of others they think are more valid. So far no rebuter has posted any such alternate models. Perhaps no alternates exist, or perhaps no one feels inclined to post a model of their own, or perhaps ......
My observation that the % reduction in AAGT during the years 2000 through 2008 is more than twice as large as the % reduction in SI during the same period, is valid independent of the arbitrariness of my models. I tentatively conclude from that that it requires a relatively small amount of SI reduction to cause a relatively large amount of AAGT reduction. Consequently, it may be true that CO2 and MAF are insignificant contributors to AAGT, since they have actually been increasing during the same period AAGT has been decreasing. If that were to be the case, then SI would be the major cause of AAGT, while CAD and MAF would be minor causes of AAGT.
