so I was off in R creating some figures to do what thatlookseasy has done just by taking them from other websites. suffice to say there is nothing in the raw, unbias data that twylght has provided that looks any different than the figures that thatlookseasy has provided.
"So now to calculate the change in temperature, we just need to know the climate sensitivity. Studies have given a possible range of values of 2 to 4.5°C warming for a doubling of CO2 (IPCC 2007), which corresponds to a range of 0.54 to 1.2°C/(W-m-2) for λ. We can then calculate the change in global temperature caused by the increase in TSIsince 1900 using the formulas above. Although Wang, Lean, and Sheeley'sreconstruction puts the change in TSI since 1900 at about 0.5 W-m-2, previous studies have shown a larger change, so we'll estimate the change in TSI at 0.5 to 2 W-m-2."
