Many of the claims made about climate change, like most social sciences, cannot be replicated which means the real world cannot be used as a way to separate the chaff from the grain.
you ignored the ask earlier; let me rephrase: given your expressed denial concerning the principal causal tie to CC/GW, which "claims made", have helped shaped and reinforced your denial... of those you claim can't be replicated?
Of course, you will insist that there is some magic that separates a fields where people manipulate tree rings to make unverifiable claims about past temperatures...
you're still clinging to concerns over decades old temperature reconstructions - still? Ah, good times: "hide the decline"... "Mike's Nature trick"... the divergence
problem effect!!!
But still? I mean, c'mon... notwithstanding other reconstruction proxies like ice-cores, lake/ocean bottom sediment, corals, etc., aren't there any reliable (confirming) tree-ring proxy reconstructions - not any? Not any multi-proxy reconstructions you accept - even those that don't use tree-rings? None?
I appreciate this board is somewhat obscure, but I understand the Mann has become somewhat litigious in wanting to protect his reputation... perhaps you can spell out your concerns (for him). Wait, what's this... just in recent weeks! C'mon - go for it!
in any case, imagine the chutzpah of CRU to prominently display this graphic on their home-page! Oh my... he shoots, he scores... with that hockey-stick!
