"The climate was stable for thousands of years"?
And the mini iceage that collapsed civilizations around the world, and left Greenland non-green.....?
And Troy being found inland?
And evidence of decades long droughts in the American west?
And the trunks of great cypress trees that used to grow along the south Texas coast?
And the evidence of Nebraska and Iowa being forested only hundreds of years ago?
Please clarify what you mean by "stable".
I think that at the least understanding what drove past dramatic climate change prior to human technology would be of interest.
The correlation you seem to cling to looks a lot like the blue light in the field the night the cow died.
