Like of a mechanism? Wait, the CERN experiments showed there was insufficient production even with the compound multipiers.
They also said that GCRs enhance the nucleation rate by up to ten times that of normal rates in the troposphere, which
is a significant rate, and changes in the GCRs can impact climate, though how significant this impact is, is still up the air.

What? Where is the evidence of the mechanism causing that cloud decrease? Not a correlation, but evidence of the specific mechanism.
See for example:

Except for the recent period where there has been a decrease in solar activity and no corresdponding decrease in temperature. Unless there is some other factor for positive temperature gain, such as GHGs you have a problem.
The GCR Flux, ACRIM TSI, the AA Index, the Solar Flux, and the Solar Cycle length all point to increasing solar activity since the 1970s.

Note the temperature starts to diverge after the start of the 20th century and is mainly above the scale at the end decade or so.
The authors of the study found that up to 70% of the warming can be attributed to the sun over the 20th Century. That is an extremely large portion for the 20th Century. The rest could be due to various other things, like the PDO/AMO, land use changes, and CO2.

The problem is the recent period.
There is no problem with 'the recent period.' Look at the charts from Scafetta and West 07 and Dorman 12.

A correlation with an evidenced mechanism is evidence of causation in such a case.
No it is not.

Not in areas which are not coastal, not immediately impacted by coastal weather patterns, or are not urban.
Then can you explain Fall et. al 2011's discovery that in the best sited stations, there is no significant DTR trend, while in the worst quality (urban contaminated) stations, there was a trend downwards?
Fall et. al 2011 finds that in the CRN 5 weather stations, there is a significant decrease in the DTR range. Keep in mind that the CRN 5 stations are the worst quality stations, with many of them being impacted by urbanization.

The graph above shows the trends in the diurnal temperature range for each type of weather station. There is no statistically significant trend in the diurnal temperature range for the best quality stations, wheras in the urbanized stations there is a statistically significant decrease in the DTR. What does this mean? It means that urbanization could account for most or all of the decrease in the DTR for most of the weather stations, since the highest quality weather stations do not display a trend in the DTR.
This also means that CO2 is not the driver of climate change in the best quality weather stations, or else we still would have observed a statistically significant decrease in the DTR in these non-urbanized weather stations, since there is no urban effect to contaminate the trends in the DTR in the best quality weather stations.
