LOL, gotta love the caveat “almost” anything. Redditers are welcome to ask Dr. Mann questions in this online forum today:
Science AMA Series: I’m Michael E. Mann, Distinguished Professor of Meteorology at Penn State, Ask Me Almost Anything! (self.science)
submitted 1 hour ago by MichaelEMann Distinguished Professor of Meteorology Penn State
I’m Michael E. Mann. I’m Distinguished Professor of Meteorology at Penn State University, with joint appointments in the Department of Geosciences and the Earth and Environmental Systems Institute (EESI). I am also director of the Penn State Earth System Science Center (ESSC). I received my undergraduate degrees in Physics and Applied Math from the University of California at Berkeley, an M.S. degree in Physics from Yale University, and a Ph.D. in Geology & Geophysics from Yale University. My research involves the use of theoretical models and observational data to better understand Earth’s climate system. I am author of more than 160 peer-reviewed and edited publications, and I have written two books including Dire Predictions: Understanding Global Warming, co-authored with my colleague Lee Kump, and more recently, “The Hockey Stick and the Climate Wars: Dispatches from the Front Lines”, recently released in paperback with a foreword by Bill Nye “The Science Guy” (www.thehockeystick.net).
“The Hockey Stick and the Climate Wars” describes my experiences in the center of the climate change debate, as a result of a graph, known as the “Hockey Stick” that my co-authors and I published a decade and a half ago. The Hockey Stick was a simple, easy-to-understand graph my colleagues and I constructed that depicts changes in Earth’s temperature back to 1000 AD. It was featured in the high-profile “Summary for Policy Makers” of the 2001 report of the Intergovernmental Panel on Climate Change (IPCC), and it quickly became an icon in the climate change debate. It also become a central object of attack by those looking to discredit the case for concern over human-caused climate change. In many cases, the attacks have been directed at me personally, in the form of threats and intimidation efforts carried out by individuals, front groups, and politicians tied to fossil fuel interests. I use my personal story as a vehicle for exploring broader issues regarding the role of skepticism in science, the uneasy relationship between science and politics, and the dangers that arise when special economic interests and those who do their bidding attempt to skew the discourse over policy-relevant areas of science.
I look forward to answering your question about climate science, climate change, and the politics surrounding it today at 2 PM EST. Ask me almost anything!

…Ask Me Almost Anything!
Yes, can you just STFU?
One of these days UCB, Yale, Penn State and maybe UVa will regret your very existence with embarrassment.

I understand you think greenhouse gases (mostly water vapor) cause the “33 degrees of warming” rather than it being already there because gravity forms an autonomous lapse rate.
So I’m asking “What is the sensitivity to a 1% change in the percentage of water vapor above any particular region?”
You see, I just want to work out if, say a wet rain forest with 4% water vapor is supposed to be about 20 degrees hotter than a dry desert with only 1% water vapor.
My problem is that a comprehensive study based on 30 years of temperature data on three continents showed that wetter regions had lower mean daily maximum and minimum temperatures than dry regions.
DocMartyn@12:36pm,
Thanks for the clarification. I still think many “distinguished” professors would avoid the adjective in a self description (especially an informal one).

I am not going there. Let them talk to each other in their closed self-gratifying box.
————————————————————————————————————-
At times that is the best response to make.
On another note, would anyone know if Mann was clean shaven back in early 2011? At that time, I was in SF staying with my sister while the State of California took care of removing the cataracts from my eyes. One morning about this time of year, I had gone down to the family restaurant in North Beach for my morning coffee. As I was weaving my way out of the always crowded restaurant, I heard a voice whisper, ‘there he is’, I snapped my head to the right. Sitting at a table next to the doorway was a group of 4 men. I locked my tiger-gaze on the one who had spoken, who was now staring open-mouthed at me. Then I turned and walked out. He looked rather similar to Mann, although he was clean shaven. Would anyone know?
[snip – I don’t like Dr. Mann’s actions any more than you do, but lets focus on the issues, not his appearance – Anthony]
That this follows so closely to “Drink Wine Day” (Feb 18), I’m thinking this is one of those examples of why people shouldn’t drink and post. I’m not saying that is what Mann did, but his post is indistinguishable from such an act.
I initially thought this was a joke. Who refers to themselves as distinguished?
The folks at reddit apparently didn’t like my question. They down-voted it until it disappeared from the page because it was below the rating threshold:
Dr. Mann,
In your famous “Nature trick” you replaced the most recent section of your proxy-derived temperature graph with a graph of *measured* temperature data, to “hide the decline” in the proxy-derived values, because that decline was inconsistent with measured temperatures. Splicing in the measured data hid the fact that the proxy-derived values were plainly wrong during that period of time, a fact which (were it not hidden) cast doubt upon your method of deriving ancient temperatures from tree ring proxies.
Phil Jones discussed using your “Nature trick of adding in the real temps to each series…to hide the decline” in this 1999 email:

This was the reaction of a prominent longtime climate alarmist, physicist Richard Muller:
Muller sounds like a cheated-on spouse. He said he’s “infuriated.” He says your team is the group he “trusted the most,” but he vows that now he’ll no longer even read your papers.
Dr. Mann, will you please take this opportunity to apologize for deceiving the community with your “Nature trick?”
Ever notice that some of these doomsdayers worried about consuming the Earth’s resources
look like they have consumed too many resources themselves?
Big Al and MM could make sure some small island sinks.

It’s probably worth getting a list of the questions he didn’t answer, though I thought he said he may do a few more tomorrow. Mine is so far unanswered:
MBH98 said: “the long-term trend in NH is relatively robust to the inclusion of dendroclimatic indicators”,
yet in your book you said: “revealed that not all of the records were playing an equal role in our reconstructions. Certain proxy data appeared to be of critical importance in establishing the reliability of the reconstruction–in particular, one set of tree ring records spanning the boreal tree line of North America published by dendroclimatologists Gordon Jacoby and Rosanne D’Arrigo”.
How can trend be robust to inclusion of indicators if certain proxy data was of critical importance?

Re: the photo of Mann – thought I had seen it before;
Turns out to have a some resemblance to Gray’s Anatomy, Fig. 1081, viz. http://www.bartleby.com/107/illus1081.html

Sorry. Apologies in advance.
My previous post @ur momisugly 11:21pm= could be mistaken, only my opinion
Question to Mann: “Can the World see you meta-data?”
Don’t touch with a barge-pole, eh, hockey stick.
“…the uneasy relationship between science and politics…”
Read: “I am uneasy that, unless I keep pumping out the unfounded and discredited climate model ‘outcomes’ that back AGW, politicians will reduce grant funding levels for our cargo cult science.”
(Where’s Barbara Walters when you need her?)
Question for Mann: If you were a tree, what kind of tree would you be?
For anyone interested I posted some proof of how the mods were covering for Mann, called out the mods only to have an /r/science mod show up and a basic number of deleted posts as the AMA went on. At 9:17pm ET there were 397 total comments and only 291 visible comments. Check it out here, http://www.reddit.com/r/climateskeptics/comments/1yj82n/micheal_mann_is_doing_an_ama_on_rscience/

LoL that’s hilarious.

Fast forward to 7:12 for a lovely demonstration of trade winds courtesy of Bill Nye’s oh so intelligent understanding of all things sciency.
++++++++++++++++++++++++++++++++++++++++++++++++++
I reckon when he moved from helping to design airplanes to comedy, the comedy over rode his engineering skills. So you really need to take everything Bill Nye says with a huge helping of salt.

Dear Mikey;
Where abouts in your colon do you predict your head will meet your foot? Or has it already happened?
Dear Mikey;
Howcome vinyards and cathedrals sprouted like weeds in the MWP?
Dear Mikey;
Which do you reckon are the more deadly: bovine eructations or flatulence?
