In reply to Ken G.
Let’s focus on the mechanisms first.
This paper by Brian Tinsley and Fangqun Yu “Atmospheric Ionization and Clouds as Links Between Solar Activity and Climate” outlines the two mechanisms.
http://www.utdallas.edu/physics/pdf/Atmos_060302.pdf
This is my attempt to summarize (See the above paper for details.)
The net effect of planetary clouds (all levels) is a reflection into space of 27.7 W/m2 (i.e. Clouds cool the planet by 27.7 W/m2.) [Hartmann, 1993] A mechanism that increases or decreases the total amount of planetary cloud cover will change the planet’s temperature.
GCR Modulation by Solar Heliosphere
Pieces of magnetic flux from the sun are carried out into the solar heliosphere. The solar heliosphere stretches out about
(edit 115 AU). The pieces of magnetic flux deflect GCR so that deflected GCR does not strike the earth. As the solar cycle progresses there is an observed change in the amount of Galactic Cosmic Ray (GCR) particles that strike the earth. Tracking the change in the number of GCR is a change total planetary cloud cover. This is shown by satellite data in Palle’s paper and also in Tinsley and Yu’s paper (figure 2.1.).
Cloud Modulation by GCR
Microscope cloud nuclei are created by the electrons that are produced when the GCR strike the upper atmosphere. (GCR create muons. The muons reach lower levels in the atmosphere and create free electrons.) Svensmark has confirmed the processes in a lab test. Two additional tests are planned. One in a deep under ground mine, to test the process in the absence of natural muons and the second with CERN, where CERN will be used to create a known modulated artificial GCR source.
Electroscavenging
High speed solar winds that are created by coronal holes (for example) remove cloud forming ions by the process of electroscavenging. The high speed solar wind creates a space charge in the earth’s ionosphere. The charge differential in the ionosphere creates a potential difference between the ionosphere and the lower atmosphere which removes cloud forming ions, from the lower atmosphere. (See figure 3.1 and figure 5.3 in Tinsley and Yu’s paper.) The ionosphere space charge is latitude specific (see figure 5.3.) Palle’s satellite analysis shows a significant reduction in clouds at the latitudes, as predicted by Tinsley and Yu.
The planetary cloud cover closely tracks GCR through two solar cycles. Around 1999 there is a gradual reduction in the earth’s total cloud cover and a reduction in the earth’s albedo based on the earthshine albedo data and satellite data. This reduction in cloud cover occurs when there is an increase in solar wind bursts due to coronal holes moving to the solar equator at the end of the solar cycle.

These times agree with those inferred from solar wind and magnetic field data. Using these times and a speed profile consistent with the observed slowing down between V2 and V1 puts the heliopause location at 115 ± 5 AU, which is near the inner limit of earlier estimates of its location but well inside the 151–158 AU inferred by the Iowa group for the new 2002 event. This difference is related to the slowing down of the interplanetary shock near the heliospheric termination shock that we find in this paper. Assuming a commonly accepted ratio of 0.75 for the heliospheric termination shock distance relative to the heliopause distance places the average termination shock location in the range ∼83–90 AU or at the distance of V1 between early 2002 and late 2003.
