An interesting discussion here:
http://tamino.wordpress.com/2007/07/24/pmod-vs-acrim/
Using ACRIM concludes:
"A better idea would be to fit a trend line to the residuals, which yields a slope of 0.01 W/m^2/yr, or 0.1 W/m^2/decade...If that trend were sustained throughout the 28-year duration of the data, it would lead to a net secular increase in TSI of 0.31 W/m^2, which would cause an increase in climate forcing of 0.076 W/m^2. That’s only marginally bigger than the climate forcing due to anthropogenic power generation. At a climate sensitivity of 0.75 deg.C/(W/m^2), it would lead to a net global temperature rise of 0.06 deg.C, far smaller than what is observed. Even using the ACRIM composite, satellite estimates of TSI will not support the idea that TSI changes are responsible for modern global warming."
Does anyone dispute the conclusion that neither TSI (total solar irradiance) composite can account for a significant fraction of the recent climate forcing?
