Richard Mackey wrote this paper about Rhodes Fairbridge and the Idea that the Solar System Regulates the Earth's Climate in 2007. It likewise projects quieter cyles 24 will be quieter than 23 and that 25 and 26 will be very quiet and result in colder decades ahead.
A similar finding was made by Archibald who speculates a major cooling ahead that could rival or be worse than the Dalton Minimum. In the hyperlinked paper, he even projects the impact on some US locations based on historical trendlines. Such a cooling would of course further call into question the idea that greenhouse gases are behind all the changes in our climate and natural factors are now suddenly unimportant. In our recent stories, we have shown how important ENSO and the multidecadal cycles in the oceans are to temperatures. It is my belief that someday we will find proof that solar changes drive the ocean cycles which drive the land temperatures.
The sun undergoes cyclical changes on multiple time scales that appear to correlate very well with temperatures. Long and relatively quiet solar cycles historically have been associated with cold global temperatures, short and very active cycles, warm periods. The current cycle 23 appears to be the longest in at least a century and may project to quieter subsequent cycles and cooling temperatures ahead.
