CR varies as solar magnetic strength varies and
that correlates with cloud cover and global temperature change.

Second: solar intensity on short term is inversely
correlated with low
cloud cover (see the reference here), which intensifies the variation and probably the long - term trend too.
In an analysis of global warming
cloud feedbacks, Dessler (2010) used short term (i.e., not climate) variations in surface temperature and CERES data to determine that
cloud cover was negatively
correlated with temperature.
There are also papers explaining the mechanisms by which specific solar cycle changes could reduce planetary
cloud cover and there is observational evidence that shows sub cycles of warming and cooling
with the sub cycles
correlating to the specific solar mechanisms during the 20 year period at which time there was satellite measurement of planetary
cloud cover.
This confirms research by Henrik Svensmark, Australia's David Evans and others, who
correlated low solar activity (fewer sunspots) and increased
cloud cover (as modulated by cosmic rays),
with a cooling climate.
From where I sit, surface temperature is most
correlated with humidity and
cloud cover.
The correlation coefficients between solar proxies and low level maritime
cloud cover are the highest,
with coefficients of − 0.130; AMO
correlates with low level continental
cloud cover at − 0.176, which is the highest coefficient for low level continental
cloud cover.
Other studies have indicated that synoptic scale changes in
cloud cover are more likely
correlated with regional climatological modes or oscillations rather than GCRs (Laken et al. 2012a).
Yes, it seems huge compared effects of increasing CO2 Abstract: «The 340 nm LER is highly
correlated with cloud and aerosol
cover becauseof the low surface reflectivity of the land and oceans (typically 2 to 6RU, where 1RU = 0.01 = 1.0 %) relative to the much higher reflectivity of
clouds plus aerosols (typically 10 to 90RU).
