Not that simple (or simple-minded).
[FONT="]". . . Rising temperatures with falling solar activity from the 1990's. The argument here is of course that the negative correlation over this period tells us that the sun cannot be the major climate driver. This too is wrong.[/FONT][FONT="]First, even if the sun was the only climate driver (which I never said is the case), this anti-correlation would not have contradicted it. Following this simple logic, we could have ruled out that the sun is warming us during the day because between noon and say 2pm, when it is typically warmest, the amount of solar radiation decreases while the temperature increases. Similarly, one could rule out the sun as our source of warmth because maximum radiation is obtained in June while July and August are typically warmer. Over the period of a month or more, solar radiation decreases but the temperature increases! The reason behind this behavior is of course the finite heat capacity of the climate system. If you heat the system for a given duration, it takes time for the system to reach equilibrium. If the heating starts to decrease while the temperature is still below equilibrium, then the temperature will continue rising as the forcing starts to decrease. Interestingly, since the late 1990’s (specifically the 1997 el Niño) the temperature has been increasing at a rate much lower than predicted by the models appearing in the IPCC reports (the so called “global warming hiatus”).[/FONT][FONT="]Having said that, it is possible to actually model the climate system while including the heat capacity, namely diffusion of heat into and out of the oceans, and include the solar and anthropogenic forcings and find out that by introducing the the solar forcing, one can get a much better fit to the 20th century warming, in which the climate sensitivity is much smaller. (Typically 1°C per CO2 doubling compared with the IPCC's canonical range of 1.5 to 4.5°C per CO2 doubling). [/FONT][FONT="]You can read about it here: Ziskin, S. & Shaviv, N.

Thanks, but I'll stick with the IPCC reports. They are authored by thousands and thousands of the top climatologists in the world.
