I reported last year on the CERN experiment which reconfirmed that cosmic rays have a strong influence on cloud formation and hence on climate. In the newly leaked draft report, the IPCC now admits to the “existence of an amplifying mechanism such as the hypothesized GCR-cloud link.”

OK, so let’s see what effect this hypothesised link would have actually had on the climate, according to solar physicists:

“We have previously placed the solar contribution to recent global warming in context using observations and without recourse to climate models. It was shown that all solar forcings of climate have declined since 1987. The present paper extends that analysis to include the effects of the various time constants with which the Earth’s climate system might react to solar forcing. The solar input waveform over the past 100 years is defined using observed and inferred galactic cosmic ray fluxes, valid for either a direct effect of cosmic rays on climate or an effect via their known correlation with total solar irradiance (TSI), or for a combination of the two.

…

The conclusions of our previous paper, that solar forcing has declined over the past 20 years while surface air temperatures have continued to rise, are shown to apply for the full range of potential time constants for the climate response to the variations in the solar forcings.”
