Muller himself encourages you to hold on to that skepticism, even if he has lost it, and even if he now thinks the IPCC report is understated. In the TImes he says:
“These facts don’t prove causality and they shouldn’t end skepticism, but they raise the bar…”

Was the study peer reviewed? He says almost all of it has been, but he is putting it out now rather than wait for completion. But in the past you have criticized the entire peer review process as largely worthless, or less than trustworthy, so I am not sure what difference it would have made for you anyway. But if we can agree on the validity of the peer review process, I’ll take that. The excuse that Watts also did not wait for peer review because of Muller is rather shallow, then.
Did Judith Curry dissent? Indeed. I was curious if she would have agreed with Muller, but she does not. But that is science…Muller himself once thought like she did, and he changed. Her opinion is valued.
Were the temperature gauges trustworthy? Clearly Watts says no, based on his non-peer reviewed study, but Muller says that he was careful in this regard…he claims that he has used 100% of the stations available rather 20%, and that he separated out good ones from bad ones.

“One final note: Even if Muller’s data is 100% correct, there is nothing in it to justify his claim that the increase in temperature is solely due to human behavior. All his data shows is that the global temperatures has risen. It does not show why.”
Well, thats Ok to have that opinion, and I’m glad to see that you distance yourself from that silly posting below from c3headlines, which said the earth was cooling. Muller has concluded differently, he believes that his leap is entirely justified given where he has come from, and he believes “…to be considered seriously, an alternative explanation must match the data at least as well as carbon dioxide does.”
Maybe that will alternative will come. But I’ll take for now those things we can agree upon: the validity of the peer review process, the fact that the temperature of the earth is rising, and that AGW believers criticize each other if they think shortcuts were taken.
