Global warming in the twenty-first century: an alternative scenario (PDF)
"Paleoclimate data (13, 32, 33) imply that the equilibrium global climate sensitivity for doubled CO2 (a forcing of about 4 W/m2) is 3 +/- 1°C (thus 3⁄4 +/- 1⁄4°C per W/m2). This figure is similar to the sensitivity derived from climate models (4, 12), but it has a higher precision and confidence level. This climate sensitivity implies a thermal response time of the ocean surface of 50–100 years (32, 34). One implication of this ocean response time is that the observed global warming of 3⁄4°C since the late 1800s is consistent with the equilibrium warming of 1.2°C that a forcing of 1.6 W/m2 implies, because about 70% of the forcing was introduced in the last 50 years (6, 35). The remaining global warming of 0.4–0.5°C that is ‘‘in the pipelineÂ’Â’ is consistent with the present planetary energy imbalance of 0.6 +/- 0.1 W/m2".
I don’t think post 241 said that there was a lag due to solar variability.
To buttress your case, you provide a link to a study by James Hansen and others. The study does not appear to consider the sun. If you don’t consider the sun, you won’t find a solar effect.
