Show us a link of THIS John Tyndall using proxies for paleo climate reconstruction and getting them upside down you STUPID ASS.
Then, one of you ignorant FOOLS can address the PILES of EMPIRICAL EVIDENCE that CO2 is a greenhouse gas and that the greenhouse effect is real.
Billy Boy, have you told your advisor yet that you reject the greenhouse effect? That should advance your fucking career by leaps and bounds.
PS, the much crowed about upside down proxies were Michael Mann's 2008 use of Tiljander's 2003 varve x-ray density data. I strongly suggest you read
Tiljander
Tiljander 2003... Tyndall 1859... yeah, I can see how YOU could get those mixed up. And then, of course, only YOU would double down on your stupidity. You REALLY need to learn how to admit your mistakes. I think if you did, you'd make less of them.
