I needed a copy of the "False Hope Graph" that Michael Mann painstakingly created for his Scientific American piece "Earth Will Cross the Climate Danger Threshold by 2036" for a presentation I'm doing, but it had to be simpler, leave some stuff off, and be readable across the room on a screen. The original graphic looks like this: It is a major contribution showing the relationship between climate sensitivity and climate change in the future depending on various important factors. The graphic I made from it is here (click on it to get the big giant version): You'll notice I left only one…
Michael Mann, Byron Steinman, and Sonya Miller have just put out a new paper on climate change which addresses a number of key concerns. The paper is called “On Forced Temperature Changes, Internal Variability and the AMO.” Here’s the abstract: We estimate the low-frequency internal variability of Northern Hemisphere (NH) mean temperature using observed temperature variations, which include both forced and internal variability components, and several alternative model simulations of the (natural + anthropogenic) forced component alone. We then generate an ensemble of alternative historical…
Well before mid century we will probably pass a threshold beyond which we'll really regret having not curtailed the release of fossil Carbon into the atmosphere in the form of Carbon Dioxide. The best case scenario for "business as usual" release of the greenhouse gas is that some of the carbon, or some of the heat (from sunlight) gets taken out of the main arena (the atmosphere and sea surface) and buried or reflected somewhere for a while, and this all happens on a slightly delayed time scale. The reason we know this is a little thing called science. And, more exactly, physics. And…
Very nice piece on MSNBC's The Reid Report. Spread this around. Nice job, Michael Mann and Bill Nye.
You probably already know about Michael Mann's book, "The Hockey Stick and the Climate Wars: Dispatches from the Front Lines." The ongoing assault on climate science in the United States has never been more aggressive, more blatant, or more widely publicized than in the case of the Hockey Stick graph -- a clear and compelling visual presentation of scientific data, put together by MichaelE. Mann and his colleagues, demonstrating that global temperatures have risen in conjunction with the increase in industrialization and the use of fossil fuels. Here was an easy-to-understand graph that, in…
This is a sea change, possibly one of the most important political changes to happen in US history. I've mentioned it before, we'll talk about it more, but for now, just watch this. Also, Michael Mann is interviewed: Visit NBCNews.com for breaking news, world news, and news about the economy
Here's a presentation by Michael Mann that I'm sure you will enjoy:
On April 2nd, I posted three iconic graphs showing some of the clear observational evidence that we’re changing the climate. That post produced a substantial, and largely thoughtful response, and a request for more information and data along these lines. Here are three more, along with a bonus fourth, all with a theme of exponential growth – the powerful force that is behind much of the concern about climate change and many other environmental and social challenges. Figures like these are increasingly called “hockey stick” curves, after the work of Professor Michael Mann and others in the…
There are two very important posts out there that I'd like to make you aware of related to climate change denialism. Here's the teasers, please click through and read them. If you like them, tweet them! First, from The Scientist, an opinion piece by Michael Mann, author of The Hockey Stick and the Climate Wars: Dispatches from the Front Lines: Life as a Target: Attacks on my work aimed at undermining climate change science have turned me into a public figure. I have come to embrace that role. As a climate scientist, I have seen my integrity perniciously attacked. Politicians have demanded I…
Michael Mann is one of the key climate scientists of the day. History will crown Mann as one of the great heroes who defended the freedom to do science rationally despite constant attacks from mean spirited and ignorant, self interested, politically motivated, oil-money-soaked climate science denialists. You know of Michael Mann as the coiner of the term "hockey stick" to refer to the alarming uptick in temperature and related measures connected to the human caused release of copious quantities of fossil Carbon into the Earth's atmosphere, causing one of the greatest disasters this planet…
Climate scientist Michael Mann is no stranger to smear campaigns. Man has the distinction of having made important contributions to climate science, for which he shared the Nobel Peace Prize. He is famous to many of you for having come up with the "hockey stick" metaphor. Michael Mann is a good scientist who has done honest, important, and high quality work, but there are those who don't want to hear about the results he and other climate scientists have come up with. So, they hate him. And by "hate" I don't mean that they sit there not liking him. I mean, they actively hate him. They…
Quite possibly Pete Sinclair's best and most important videos yet. Click here to get more background from Peter Sinclair's site. The post refers to this book: The Hockey Stick and the Climate Wars: Dispatches from the Front Lines
Peter Sinclair has a good run down of recent politically motivated FOIA fishing expeditions into climate and other scientist emails. It includes mention of the recent good news in the ATI v UVa case where the court agreed with UVa that the ATI and their lawyers could not be trusted to see emails UVa has claimed should be exempt from the FOIA request for the purpose of challenging that excemption. Ouch. But good call, I am sure. Peter also includes mention of an excellent non-climate science related example of the same tactic in the case of a Wisconsin history professor, William Cronon,…
You've heard about "ClimateGate." ClimateGate was a very successful but illegal campaign by anti-science to discredit climate science and climate scientists. Rest assured, the climate science is fine and the climate scientists are just trying to do their jobs, and doing quite well at that. Nonetheless, a combination of inaccurate representation of the contents of various emails written between climate scientists and what amounts to unethical treatment of climate science by the press resulted in a shift among the general populous in the US from about half of the people thinking that Global…
Barak Obama has finally released his long form birth certificate. Will it satisfy the Birthers? (Yes, there is a climate connection. Check the links!)
The sorry saga continues... WASHINGTON (October 21, 2010) - Yesterday, the University of Virginia made two court filings in its fight against Virginia Attorney General Ken Cuccinelli's politically motivated investigation of climate scientist Michael Mann. In its most strongly-worded court filing to date (pdf), UVA characterized Cuccinelli's investigation as "an unprecedented and improper governmental intrusion into ongoing scientific research" and said that Cuccinelli is targeting Mann because he "disagrees with his academic research regarding climate change." UVA also argued that Cuccinelli'…
Following vindications from the NRC panel, the independent Penn State Committee, the House of Commons report, the International Panel, the Penn state Investigatory Committee, the Independent Climate Change Email Review has reported On the specific allegations made against the behaviour of CRU scientists, we find that their rigour and honesty as scientists are not in doubt. ... we did not find any evidence of behaviour that might undermine the conclusions of the IPCC assessments. ... But we do find that there has been a consistent pattern of failing to display the proper degree of openness On…
When you're investigating charges that a scientist has seriously deviated from accepted practices for proposing, conducting, or reporting research, how do you establish what the accepted practices are? In the wake of ClimateGate, this was the task facing the Investigatory Committee at Penn State University investigating the allegation (which the earlier Inquiry Committee deemed worthy of an investigation) that Dr. Michael E. Mann "engage[d] in, or participate[d] in, directly or indirectly, ... actions that seriously deviated from accepted practices within the academic community for…
Way back in early February, we discussed the findings of the misconduct inquiry against Michael Mann, an inquiry that Penn State University mounted in the wake of "numerous communications (emails, phone calls, and letters) accusing Dr. Michael E. Mann of having engaged in acts that included manipulating data, destroying records and colluding to hamper the progress of scientific discourse around the issue of global warming from approximately 1998". Those numerous communications, of course, followed upon the well-publicized release of purloined email messages from the Climate Research Unit (…
Penn State investigation concludes: The Investigatory Committee, after careful review of all available evidence, determined that there is no substance to the allegation against Dr. Michael E. Mann, Professor, Department of Meteorology, The Pennsylvania State University. More specifically, the Investigatory Committee determined that Dr. Michael E. Mann did not engage in, nor did he participate in, directly or indirectly, any actions that seriously deviated from accepted practices within the academic community for proposing, conducting, or reporting research, or other scholarly activities.
