IPCC's Southern Hemisphere Reconstruction – Made With European Instrumental Record!

Steve McIntyre (emphasis mine):

A question for readers: which of the following proxies are used to reconstruct past Southern Hemisphere temperature in the IPCC’s graphic (Figure 5.7b) showing SH reconstructions:

1. Graybill’s California strip-bark bristlecone chronologies
2. upside down and contaminated Finnish lake sediments
3. European instrumental temperature data
4. Antarctic ice core d18O isotope data covering the medieval period

The answer, rather remarkably, is that IPCC’s SH temperature reconstructions in their signature spaghetti graph (Figure 5.7b) used California bristlecone chronologies, upside down Tiljander and European instrumental temperature data, but did not use Antarctic isotope data covering the medieval period. …

What I find interesting is that Michael Mann hasn't been recognized as the hack he is.

Maybe in two or three decades people will look back at the current period and mutter things like "… they were so stupid back then …", only to follow new hacks (all the while telling themselves "… thankfully this can't happen today …"). But maybe it will take longer.

Will I see the day when Michael Mann fully gets the credit he rightfully deserves? After all, people still think that Robert Gallo was helpful in discovering HIV…
