The paper he wrote together with Friis - Christensen in which he found a correlation between solar activity and clouds had a «slight» flaw: it ignored that the period of the study coincided with a big El Nino, and that large scale changes in ocean surface temperature are going to have an effect on cloud formation.
In fact, all climate models do predict that the change in globally - averaged steady state temperature, at least, is almost exactly proportional to the change in net radiative forcing, indicating a near - linear response of the climate, at least on the broadest scales.

``... it is now very likely that anthropogenic forcing has contributed to the observed changes in the frequency and intensity of daily temperature extremes on the global scale since the mid-20th century.
Ice cores show atmospheric CO2 variations to lag behind atmospheric temperature changes on a century to millenium scale, but modern temperature is expected to lag changes in atmospheric CO2, as the atmospheric temperature increase since about 1975 generally is assumed to be caused by the modern increase in CO2.
