Climate Change Dialogue III

ME: How do you feel about the following two quotes?

“Suddenly the hockey stick, the poster-child of the global warming community, turns out to be an artifact of poor mathematics. That discovery hit me like a bombshell, and I suspect it is having the same effect on many others. How could it happen?”
Richard Muller October 2004
OF: From what I’ve read about Mr. Mann’s hockey stick theory, I definitely agree with the comment.
ME: How about this one?
“It’s a scientist’s duty to be properly skeptical. I still find that much, if not most, of what is attributed to climate change is speculative, exaggerated or just plain wrong. I’ve analyzed some of the most alarmist claims, and my skepticism about them hasn’t changed.” Richard Muller July 2012

OF: I think the second comment hits on what I’ve been saying for a long time … there can’t be that many “climate scientists” on the planet … we wind up with a lot of people with degrees in biology and other scientific fields writing articles on things well beyond their core competency, but it’s all feel-good sort of stuff and gets lots of support.

ME: OK, Old Friend, this is my last shot; I’ll leave you alone on this subject after this. Those quotes by Richard Muller, a global warming denier questioned the temperature statistics used by climatologists. He created Berkeley Earth address potential biases in the land surface temperature record and got grants, among others a $150,000 grant from the Charles G. Koch Charitable Foundation. He felt there were biases from urban heating, from data selection, from poor station quality and from human intervention and data adjustment.
Please take a serious look at this research and tell me how it is flawed.

OF: while I’m reviewing what you sent, please take a squint at this:

Subject: Amid criticism, Berkeley Earth extends record, upholds findings : Nature News Blog

Apparently some folks think Mr Muller is a flipping idiot … certainly not me … I do hope he’s not doing that tree ring thing

ME: Thanks for this link. I enjoyed it immensely especially the link to climatologist Judith Curry’s blog where I found this quote from climatologist Ken Caldeira:
I am glad that Muller et al have taken a look at the data and have come to essentially the same conclusion that nearly everyone else had come to more than a decade ago. The basic scientific results have been established for a long time now, so I do not see the results of Muller et al as being scientifically important. However, their result may be politically important. It shows that even people who suspect climate scientists of being charlatans, when they take a hard look at the data, see that the climate scientists have been right all along.

***I am looking forward to my friend’s response to the Berkley Earth research and conclusions in which Professor Muller states:

“Much to my surprise, by far the best match was to the record of atmospheric carbon dioxide, measured from atmospheric samples and air trapped in polar ice.” Muller emphasizes that the match between the data and the theory doesn’t prove that carbon dioxide is responsible for the warming but the good fit makes it the strongest contender. “To be considered seriously, any alternative explanation must match the data at least as well as does carbon dioxide.”
