The Marcot et al is "not robust" (their words at RealClimate) so that "scary" ski jump graph is invalid, this obviously hasn't penetrated Climate (lack of) Progress yet.
PAGES2k seems to recycle a lot of papers which have been challenged, junked, and even in one case withdrawn due to major error (Gergis et al 2012). (EDIT - retraction notice
here).
If I was in someway suspicious of some scientists I could potentially think that it was made up to get these dead papers into the next IPCC report - not that they would do that of course,
unlike before.
Did you notice this
one from Antarctica ? Not so scary either.
Or this one on
lower sensitivity again ?
