The Price Of Wheat and Sunspots in 1800 England

As early as 1800, an English astronomer noted that the price of wheat went up when there were fewer sunspots.
Now we know this was related to natural global cooling. Fewer sunspots meant less electromagnetic radiation from the sun which resulted in less interference with cosmic radiation that helps nucleate low cloud formation which, in turn, meant cloudy cool summers, and this was not good for wheat production and hence the higher wheat prices.
The reverse has been true for the past decade or so; more sunspots than usual have been observed and thus more interference with cosmic radiation reaching the lower atmosphere and therefore fewer low clouds and warmer weather. GLOBAL WARMING!
This has nothing to do with man-made CO2 but there is no world to save and no lucrative contracts from which to profit if this natural phenomenon is at play.
Much to the dismay of man-made global warming profiteers, this is one possible driving mechanism for global warming or cooling over periods of  a few years or decades, riding on top of changes that occur over thousands of years.
