There is no evidence that CO2 levels effect climate; either long term, as seen in the graph below; intermediate term, as in throughout the Holocene; or short term, like over the last 150 years. The so called greenhouse effect (which by the way is a poor choice of name since a greenhouse is a closed system and the atmosphere is not) is dominated by water vapor. There is theory and evidence that any possible effects of added CO2 is negated by negative H2O feedbacks for example: clouds in the lower atmosphere. If CO2 has any effect at all then it acts as a radiative thermal insulator. As such, added CO2 will cause increases in temperature in the lower troposphere but decreases in temperature in the upper troposphere where SWIR is radiated out to space. If temperatures drop so does H2O content which negates the effect of added CO2. This alone constitutes a substantial theoretical and evidential basis against the idea of AGW. As you both claim, solar forces alone does not account for the warming that we have been observing over the past 100 years but if one would just turn up the solar activity climate warming gain by assuming a relationship between solar activity and albedo then CO2 based warming is not required to account for what we have been observing.
