Those average swings are very gradual, but even in a cooling cycle the SunSpots will alter a few days to a few weeks with unseasonable weather changes.
An idea for those Army worms would be Salt of the Earth, water and electic, and a cold period.
In 2006, my father told me he had the data and it was pubically availabled to show the temp swings... but he also said he was ashamed that he bought into the SCARE for first 70 years of his life and that he knew the government was using Global Warming/Cooling and now Climate Change to TAX.
That’s interesting. Did he tell you anything about The Plan from Iron Mountain? That was a plan where they were think tanking about peace.
They felt that some sort of threat was needed to replace war, and Global Climate catastrophe was just one of the options, alien enemies was another. This group also felt that open borders and no nation state was needed too.
The news media of course claimed it was conspiracy, and someone wrote a book that they called a hoax. The book was republished in 2008, I think.
The Government lies all the time. If you ever read some of their white papers or studies, it makes you think we might be governed by idiots. However, if you follow the money, then you’ll see the real reason for some of the nonsense.
I recently read a study though, that showed that sometimes in the past, there has been sudden changes and those are tied to break down of the flow related to saltiness - can’t remember the technical terms, but it could result in lots of water in a short time, and require relocation of people on the Coasts and along the Mississippi. They emphasized, though that they were not saying it was the most likely thing, just that it could happen. So they monitor the salt content.
