Year to year changes are "NOISE." California had a drought for several years (virtually a blip in time) and then come the rains. It happens over an over.
Sun spot cycles are repetitive. Mega-Rains come to California every 160 years or so. Last time was 1862, so 2022 look out. These are formed over decades of hot water buildup in the Eastern equatorial Pacific.
Cycles have been consistent over centuries and it looks like they are changing now due to more limited solar input.
How these longer term cycles & their variences affect the Earth don't seem to be of concern in current evaluations where people are only interested in year to year or decade to decade changes.
Long term cycles are not "sexy", but may hold the fate of nations in their hands because of long term weather changes to dry or wet which cause massive changes in growing regions which means food for billions of people.
