Ummm, errr... from my life, it just seems like common knowledge...

I was introduced to a theory long ago.
That ice-ages aren't just about it getting cold. If it is just cold, then there is no rain to make huge glaciers, and then from that, this and this and this have to be true.

Sooo, i am watching things unfold, and this and this and this are happening exactly along the lines of the theory.

Anyway, ice age farmer used to talk about it on Steem

Here he is on bitchute, but i do not know which of his current stuff is on ice-age.

It will become very apparent that we are in an ice-age soon.
i am sorry, i do not know how to explain what has become a foundation of my thinking.
And i do not know how to find the books that started this way back then...
