Muscheler retracts? Offers a NEW excuse for why solar activity can't be responsible for post-70's warming
Guest post by Alec Rawls Technically Dr. Muscheler is asking me to retract the title of my post, “Raimund Muscheler says that a steady high level of forcing can’t cause warming“:…
Linking the ENSO and PDO induced rainfall of the Pacific Northwest to proxy data in tree rings and lake sediments
From Penn State , another Mann paper with proxy sets, and a divergence problem. At least they are talking about the MWP, or as they call it, the Medieval Climate…
