I have commented upon the Dr. Murry Salby presentation recently touted by the critics of the academic climate science consensus, at the claes johnson site:
I prefer the summary analysis presented at appinsys.com. And if you look at the temperature record (the first graph at the appinsys link), you will see what everyone should know, that the temperature decreased from 1880 to 1910, increased from 1910 to 1940, decreased again from 1940 to 1975, and increased again from 1975 to about 2000. Now the CO2 record from 1957 onward shows dC/dt has increased monotonically over that period, i.e., d/dt(dC/dt)>0 from at least 1957 onward. But your CO2 vs. T relation above requires d/dt(dC/dt)=dT/dt, and dT/dt was negative from 1940 to 1975 (including the period 1957 to 1975). So the posited relation dC/dt=T is empirically wrong. And physically, that relation flies in the face of what I (a general physicist, not a climate scientist) have heard repeatedly as common knowledge: That a warmer ocean cannot hold as much CO2 dissolved in it, and releases more CO2 into the atmosphere the warmer it gets (in line with the skeptic's claim, "atmospheric CO2 follows temperature, not vice-versa as the consensus claims"). So the posited CO2 vs. T relation is also falsified according to (the general understanding of) the basic physics of CO2 sequestration by the ocean as a function of T. So, again, I prefer the appinsys summary of the situation. I commented on Dr. Salby's presentation at hockeyschtick also.
