Thank you for your considered response.
MBH98 was 20 years ago. https://en.wikipedia.org/wiki/Hockey_stick_graph goes into details about the various analyzes of MBH98 and later, including criticisms and counter-criticisms. The Moberg 2005 analysis I referenced above is one of them, which used wavelet transforms instead of PCA. It found similar conclusions as MBH99, the extension of MBH98.
> A 2010 opinion piece by David Frank, Jan Esper, Eduardo Zorita and Rob Wilson (Frank et al. 2010) noted that by then over two dozen large-scale climate reconstructions had been published, showing a broad consensus that there had been exceptional 20th century warming after earlier climatic phases, notably the Medieval Warm Period and Little Ice Age
It then adds that more reconstructions have been done since then, again following the broad consensus.
they should be read and considered rather than being rejected out of hand.
This goes back to my original objection, which is that the g'g' etc. poster didn't point to something to read, other than "Willis Eschenbach's work over on https://wattsupwiththat.com/ ".
I can certainly reject out of hand the undirected suggestion to read hundreds if not thousands of blog posts without having some solid reason to believe it's worthwhile, especially given that several of the poster's other comments on the topic seemed to be wrong, and internally inconsistent.
