The forcing from changes in total solar irradiance alone does not seem to account for these observations, implying the existence of an amplifying mechanism such as the hypothesized GCR-cloud link.
One of the fifteen lead authors of chapter 7 responded that the evidence for one of the proposed mechanisms of solar amplification, GCR-cloud, indicates a weak effect, and proceeded as if this obviated the IPCC’s admission that some such mechanism must be having a substantial effect:
[Professor Steven Sherwood] says the idea that the chapter he authored confirms a greater role for solar and…
