Zim, I think it is a lot more complicated than that. Also, while there is variability of the sun's output, I'm not aware of any evidence that it varies a LOT, and then holds those changes in output for thousands of years, are you?
I know Armstrong says we are in a solar cooling period until about 2034. So far, I don't see that much cooling.
I understand there is a wobble in the earth's rotation which is believed to have created a period of regularl rainfall in the Sahara from (if memory serves me) about 25K BC to about 10K BC. Then it shifted into this dryer phase. If that wobble holds up as the determinant, then the Sahara will bloom with life again in about another 1,000 years.
And then, quoting further from the article I cited previously:
"These large ice ages can have smaller ice ages (called glacials) and warmer periods (called interglacials) within them. During the beginning of the Quaternary glaciation, from about 2.7 million to 1 million years ago, these cold glacial periods occurred every 41,000 years. However, during the last 800,000 years, huge glacial sheets have appeared less frequently — about every 100,000 years, Sandstrom said.
This is how the 100,000-year cycle works: Ice sheets grow for about 90,000 years and then take about 10,000 years to collapse during warmer periods. Then, the process repeats itself."
And THEN there is volcanism -- a huge arbiter of "climate change".
And the climate change sure took those dinosaurs by surprise when the asteroid hit!
The only thing which seems certain is that the climate is always going through one change or another.
Also, that predicted "global warming", even if it happens, cannot be known to necessarily be worse than what was coming anyway, and certainly not worse than what has already been.
