Sun’s output has barely changed since 1970 & is irrelevant to recent global warming

Ben Lankamp at 06:24 AM on 13 September, 2007 Biocab: surely you can agree with the consensus that solar irradiance has not increased significantly in the last 50 years, while the global average temperature has? The only conclusion can be that changes in solar irradiance cannot have contributed to recent warming in the last half century. With regard to CO2: I think you are not completely aware of the exact concept of the natural greenhouse effect, the enhanced greenhouse effect and most important of all radiative forcing. I am not an expert on the exact chemistry of all the trace gases and how that works, so I cannot judge your comments on the exact emissivity (though my gut feeling hints at the missing of the immediate re-emittance of longwave IR-radiation while you seem to be talking only about the independent emittance of the absorbed heat). I do know the following thou...
