Hi Ken G. in reply to your comments.
Which points do we agree on or disagree on?
1) In addition to correlation, there must be a mechanism to cause the change. In the case, of this problem, there is paleoclimatic evidence of semi cyclical abrupt changes in planetary temperature. As noted above, concurrent with the planetary temperature changes is an observed change in the solar magnetic field cycle. (Correlation does not prove cause. And in addition the solar magnetic field changes may be the trigger but other planetary climate forcing functions could amplify the solar magnetic field changes.)
2) A hypothesized mechanism was provided as to how solar magnetic field changes could affect planetary temperature. There is some observational evidence that supports the solar magnetic field mechanism. (The predicted increase and decrease in planetary clouds was observed over oceans and at latitudes as predicted by the hypothesis.)
3) Additional observations are required to determine if the solar magnetic cycle, modulation of planetary cloud hypothesis is correct and to determine the appropriate weighting for the different climatic forcing functions. This issue has not been resolved in the scientific community.
4) If the solar magnetic modulation of cloud hypothesis is correct and there is a slow down in cycle 24 the planet should cool. If the solar magnetic modulation of cloud hypothesis is not correct, there will be no change or a minor change. (Comment: Researchers agree there should based on solar modelling theories be a slow down in cycle 25. There is not agreement as to whether there will be a slow down in solar cycle 24.)
A link was provided above to Palle’s satellite paper that found 99.9% correlation between planetary cloud cover and GCR changes 1992 to 2001, when adjusted for the effect of electroscavenging. Below is a link to Palle’s earthshine paper that provides data to support a reduction in planetary albedo (less clouds) 1994 to 2001, which Palle states is equivalent to a forcing of 7.5W/M^2.

This discovery (see link below) supports the existence of some mechanism that can simultaneously reduce planetary temperature in both hemispheres.

"...Because the Earth is oriented in space in such a way that the hemispheres are out of phase in terms of the amount of solar radiation they receive, it is surprising to find that the climate in the Southern Hemisphere cooled off repeatedly during a period when it received its largest dose of solar radiation," says Singer. "Moreover, this rapid synchronization of atmospheric temperature between the polar hemispheres appears to have occurred during both of the last major ice ages that gripped the Earth..."
