We see from the past post us technical guys like reader kdk33, can pick up on the more obvious flaws of paleoclimate pretty quickly. Honestly there are times when I feel sorry for Mann, his role in history will not be a good one in the long term but it was brought about by an initial mistake in his early papers. After the accolades he received for his 98, 99 work the censored directory was created with a corrected PCA reconstruction. What should he do, phone the UN — um world, I screwed up a little…..
His reaction, of course, has been the opposite. He doubled down, creating one reconstruction after another using math which is actually worse than the original. Food for skeptics! Leading to Pielke Jr’s writing of my single favorite quote in all of climate science:
If Michael Mann did not exist, the skeptics would have to invent him.
Damn that’s good.
So here’s the question,
Where would the IPCC be without the proxy based reconstructions?
It’s a scary question because if the climatologists were to excise the bad paleo stuff, IMHO the AGW story is strengthened rather than damaged.
