Maybe the answer lies in the quiet sun. As of this very moment, still very, very few sunspots in this current cycle. Climate science has drunk the AGW KoolAid and is not interested in any other climate models. Well, there is another climate model, one where the correlation between climate swings and solar activity is very high.
Indeed, climate science loves their models going forward, but few scientists seem interested in back-testing them, especially to test them against the 1800’s when snow in July caused such massive crop failures that many died from famine.
This corresponded to a sunspot cycle that lacked sunspots, a period that was named the Maunder Minimum. So far, this current cycle seems to mimic the paucity of sunspots during that time. If we have a similar paucity, we can expect similar weather disasters.
