Even tho I didn't bring up solar irradiance and the graph is irrelevant. There is strong correlation between the two shown on that graph UNTIL about 1980.. As a scientist -- I find that fascinating. Don't you? Why DIDN'T the correlation continue?
Insolation was largely based upon surface measurements up until the late seventies/early eighties and aerosols largely masked many of the CO2 increase impacts of the time, until the clean air acts in US, Europe and most of the developed world in the '70s began clearing these aerosols out of the atmosphere and the beyond the atmosphere orbital solar obervatories began building much more accurate incident TSI information. The actual divergence of strongly correlated TSI and surface temps begins in the late '40s-mid '50s (when TSI significantly exceeds previous surface temperature correlation ratios - it isn't initially that solar irradiance declined, its that temps began to fall while TSI continued to increase - the signature of masking in association with the wartime activities and industrializations of many parts of the planet to support that war and in recovery from it).
