What is the scientific evidence for CO2's effect on heat retention? I have read Eunice Foote's "Pioneering Research On CO2 And Climate Warming" with data form 1856. I have only seen the data taken on faith and no testing. Has it been tested? - John Walker, former Laboratory Medical Director/Pathologist (1984-2011)
