Michael Mann.. Deception and Misinformation

A movie put out staring Michale Mann has over 20 deceptions and lies that can be shown by empirical evidence to be lies or outright deceptions in an effort to gain monetary influence...

Conclusion
The perpetrators of the offending video are, so they think, so well protected by the current U.S. Administration’s prejudice on the climate question that they can get away with a campaign of multiple, wilful, mutually reinforcing and no doubt profitable deceptions on this monstrous scale with impunity, to the detriment not only of the truth but also of two diligent and hard-working scientists.

Without saying anything more in public at this stage, we shall see. In the meantime, readers may care to recall the terms of 18 U.S. Criminal Code §1343 (wire fraud):
“Whoever, having devised or intending to devise any scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises, transmits or causes to be transmitted by means of wire, radio, or television communication in interstate or foreign commerce, any writings, signs, signals, pictures, or sounds for the purpose of executing such scheme or artifice, shall be fined under this title or imprisoned not more than 20 years, or both.”

It may be just me, but there is hint that a criminal/civil prosecution might be in the works over this... Me thinks Mann just stepped on his Johnson, hard and it is about to come back to haunt him...

Its stuff like this that is about to hit alarmists real hard..

Any more cherry picking and this thing will be a pie.... You simply cant make this up.. The facts are about to kick them in the ass....

20 false representations in one 10-minute video

Sounds like the IPCC and their enablers here in the US could be delat with on legal grounds...

Yet Micheal Mann has scientists in every nation and culture that state that by their observations, he is correct. And who does Silly Billy have? LOL. Fellow fruitloops, crackpots, and fakers.

An appeal to authority, and exactly no evidence to support your supposition, while the link I provided gives ample facts for the case. And then you end it with an adhominem attack..

Standard alarmist drivel...

Yup. Old Rocks cannot separate what is being said from who is saying it. You cannot convince him with evidence. Nothing is valid until it has been properly vetted by the right kind of authority.

 

[Old Rocks]

Ah yes, undegreed ex-TV weathermen, obese junkies on the AM radio, and fake British Lords are so much more knowledgeable than real scientists.

From Cazenave 2009:

From this, one obtains a number representing the GMSL for each repeat period, which in the case of T/P and Jason-1/2 is 10 days. Numerous authors have used altimetry to estimate present-day GMSL from altimetry. The most recent estimated linear trends generally agree that sea level has been rising at a rate in the range 3.0 to 3.5 mm/yr since 1992 (e.g., [8-10]). Differences are generally due to the time-span used to estimate the linear trend, and to differences in satellite orbits and geophysical corrections applied to the data. Fig. 2 compares T/P and Jason altimetry-derived sea level curves from two groups (seasonal signal removed; inverted barometer correction and 60-day smoothing applied). The trend over the 1993-2008 time span is similar for the two curves and amounts to 3.3 ± 0.4 mm/year (after correcting for the -0.3 mm/yr glacial isostatic adjustment or GIA effect, [11]). Some differences are noticed at sub-annual and interannual time scale.

They are ACTIVIST first --- and scientists 2nd -- and hiding out in labcoats. That's how Mann got rich and Hansen got the gig at NASA..

Early life and education[edit]

Hansen was born in Denison, Iowa to James Ivan Hansen and Gladys Ray Hansen.[9] He was trained in physics and astronomy in the space science program of James Van Allenat the University of Iowa. He obtained a B.A. in Physics and Mathematics with highest distinction in 1963, an M.S. in Astronomy in 1965 and a Ph.D. in Physics, in 1967, all three degrees from the University of Iowa. He participated in the NASA graduate traineeship from 1962 to 1966 and, at the same time, between 1965 and 1966, he was a visiting student at the Institute of Astrophysics at the University of Kyoto and in the Department of Astronomy at the University of Tokyo. Hansen then began work at the Goddard Institute for Space Studies in 1967.[10]
Career[edit]

After graduate school, Hansen continued his work with radiative transfer models, attempting to understand the Venusian atmosphere. Later he applied and refined these models to understand the Earth's atmosphere, in particular, the effects that aerosols and trace gases have on Earth's climate. Hansen's development and use of global climate modelshas contributed to the further understanding of the Earth's climate. In 2009 his first book, Storms of My Grandchildren, was published.[11] In 2012 he presented a 2012 TED Talk: Why I must speak out about climate change.[12]
From 1981 to 2013, he was the head of the NASA Goddard Institute for Space Studies in New York City, a part of the Goddard Space Flight Center in Greenbelt, Maryland.
As of 2014, Hansen directs the Program on Climate Science, Awareness and Solutions at Columbia University's Earth Institute.[13] The program is working to continue to "connect the dots" from advancing basic climate science to promoting public awareness to advocating policy actions.

Early life, undergraduate studies[edit]

Mann was born in 1965, and brought up in Amherst, Massachusetts, where his father was a professor of mathematics at the University of Massachusetts. At school he was interested in math, science, and computing. In 1983 he was prompted by seeing the film WarGames to write a rudimentary self-learning tic-tac-toe program which made random moves and listed losing moves which it would not repeat. Mann found a "trick" of using symmetry to reduce the number of unique moves to store so that the computer would not slow down so much.[4]
In August 1984 he went to the University of California, Berkeley, to major in physics with a second major in applied math. His second year research in the theoretical behaviour ofliquid crystals used the Monte Carlo method applying randomness in computer simulations. Late in 1987 he joined a research team under Didier de Fontaine which was using similar Monte Carlo methodology to investigate the superconducting properties of yttrium barium copper oxide, modelling transitions between ordered and disordered phases.[5]He graduated with honors in 1989 with an A.B. in applied mathematics and physics.[1]
Doctoral and postgraduate studies[edit]

Mann then attended Yale University, intending to obtain a PhD in physics, and received both an MS and an MPhil in physics in 1991. His interest was in theoretical condensed matter physics but he found himself being pushed towards detailed semiconductor work. He looked at course options with a wider topic area, and was enthused by PhD adviserBarry Saltzman about climate modelling and research. To try this out he spent the summer of 1991 assisting a postdoctoral researcher in simulating the period of peakCretaceous warmth when CO2 levels were high, but fossils indicated most warming at the poles, with little warming in the tropics. Mann then joined the Yale Department of Geology and Geophysics, obtaining an MPhil in geology and geophysics in 1993. His research focused on natural variability and climate oscillations. He worked with the seismologist Jeffrey Park, and their joint research adapted a statistical method developed for identifying seismological oscillations to find various periodicities in the instrumental temperature record, the longest being about 60 to 80 years. The paper Mann and Park published in December 1994 came to similar conclusions to a study developed in parallel using different methodology and published in January of that year, which found what was later called the Atlantic multidecadal oscillation.[6]
In 1994, Mann participated as a graduate student in the inaugural workshop of the National Center for Atmospheric Research's Geophysical Statistics Project aimed at encouraging active collaboration between statisticians, climatologists and atmospheric scientists. Leading statisticians participated, including Grace Wahba and Arthur P. Dempster.[7]
While still finishing his PhD research, Mann met UMass climate science professor Raymond S. Bradley and began research in collaboration with him and Park. Their research used paleoclimate proxy data from Bradley's previous work and methods Mann had developed with Park, to find oscillations in the longer proxy records. "Global Interdecadal and Century-Scale Climate Oscillations During the Past Five Centuries" was published by Nature in November 1995.[8]
Another study by Mann and Park raised a minor technical issue with a climate model about human influence on climate change: this was published in 1996. In the context of controversy over the IPCC Second Assessment Report the paper was praised by those opposed to action on climate change, and the conservative organisation Accuracy in Media claimed that it had not been publicised due to media bias. Mann defended his PhD thesis on A study of ocean-atmosphere interaction and low-frequency variability of the climate system in the spring of 1996,[9][10] and was awarded the Phillip M. Orville Prize for outstanding dissertation in the earth sciences in the following year. He was granted his PhD in geology and geophysics in 1998.[1]
Postdoctoral research: the hockey stick graph[edit]

Michael Mann speaking about "The Hockey Stick and the Climate Wars" at The Amaz!ng Meeting in Las Vegas, July 13, 2013​

From 1996–1998, after defending his PhD thesis at Yale, Mann carried out paleoclimatology research at the University of Massachusetts Amherst funded by a United States Department of Energy postdoctoral fellowship. He collaborated with Raymond S. Bradley and Bradley's colleague Malcolm K. Hughes, a Professor of Dendrochronology at the University of Arizona, with the aim of developing and applying an improved statistical approach to climate proxy reconstructions. He taught a course in Data Analysis and Climate Change in 1997 and became a Research Assistant Professor the following year.[1][11]
The first truly quantitative reconstruction of Northern Hemisphere temperatures had been published in 1993 by Bradley and Phil Jones, but it and subsequent reconstructions compiled averages for decades, covering the whole hemisphere. Mann wanted temperatures of individual years showing differences between regions, to find spatial patterns showing natural oscillations and the effect of events such as volcanic eruptions. Sophisticated statistical methods had already been applied to dendroclimatology, but to get wider geographical coverage these tree ring records had to be related to sparser proxies such as ice cores, corals and lake sediments. To avoid giving too much weight to the more numerous tree data, Mann, Bradley and Hughes used the statistical procedure of principal component analysis to represent these larger datasets in terms of a small number of representative series and compare them to the sparser proxy records. The same procedure was also used to represent key information in the instrumental temperature record for comparison with the proxy series, enabling validationof the reconstruction. They chose the period 1902–1980 for calibration, leaving the previous 50 years of instrumental data for validation. This showed that the statistical reconstructions were only skillful (statistically meaningful) back to 1400.[12]
Their study highlighted interesting findings, such as confirming anecdotal evidence that there had been a strong El Niño in 1791, and finding that in 1816 the "Year Without a Summer" in Eurasia and much of North America had been offset by warmer than usual temperatures in Labrador and the Middle East. It was also an advance on earlier reconstructions in that it went back further, showed individual years, and showed uncertainty with error bars."[13] Global-scale temperature patterns and climate forcing over the past six centuries" (MBH98) was published on April 23, 1998 in the journalNature. In it, "Spatially resolved global reconstructions of annual surface temperature patterns" were related to "changes in greenhouse-gas concentrations, solar irradiance, and volcanic aerosols" leading to the conclusion that "each of these factors has contributed to the climate variability of the past 400 years, with greenhouse gases emerging as the dominant forcing during the twentieth century. Northern Hemisphere mean annual temperatures for three of the past eight years are warmer than any other year since (at least) AD 1400.[14] The last point received most media attention. Mann was surprised by the extent of coverage which may have been due to chance release of the paper on Earth Dayin an unusually warm year. In a CNN interview, John Roberts repeatedly asked him if it proved that humans were responsible for global warming, to which he would go no further than that it was "highly suggestive" of that inference.[15]
In May 1998, Jones, Briffa and colleagues published a reconstruction going back a thousand years, but not specifically estimating uncertainties. As Bradley recalls, Mann's initial reaction to the paper was "Look at this. This is rubbish. You can't do this. There isn't enough information. There's too much uncertainty." Bradley suggested using the MBH98 methodology to go further back. Within a few weeks, Mann responded that to his surprise, "There is a certain amount of skill. We can actually say something, although there are large uncertainties."[16][17] Mann carried out a series of statistical sensitivity tests on 24 long term datasets, in which he statistically "censored" each proxy in turn to see the effect its removal had on the result. He found that a dataset which would otherwise have been reliable diverged from 1800 until around 1900, suggesting that it had been affected for that time by the CO2 "fertilisation effect". Using this dataset corrected in comparisons with other tree series, their reconstruction passed the validation tests for the extended period, but they were cautious about the increased uncertainties involved.[18]
The Mann, Bradley and Hughes reconstruction covering 1,000 years (MBH99) was published by Geophysical Research Letters in March 1999 with the cautious title Northern Hemisphere temperatures during the past millennium: inferences, uncertainties, and limitations.[17][19] Mann said that "As you go back farther in time, the data becomes sketchier. One can't quite pin things down as well, but, our results do reveal that significant changes have occurred, and temperatures in the latter 20th century have been exceptionally warm compared to the preceding 900 years. Though substantial uncertainties exist in the estimates, these are nonetheless startling revelations."[20] When Mann gave a talk about the study to the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory, climatologist Jerry D. Mahlman nicknamed the graph the "hockey stick".[17]
Career[edit]

University of Virginia​

University positions[edit]

In 1999, Mann secured a position as a tenure-track assistant professor in the Department of Environmental Sciences at the University of Virginia. He left Virginia in 2005 to become an associate professor in the Department of Meteorology (with joint appointments in Department of Geosciences and Earth and Environmental Systems Institute) at Pennsylvania State University, where he was also appointed the Director of its Earth System Science Center. He was promoted to full professor in 2009 and to "Distinguished Professor of Meteorology" in 2013.[1]

Michael Mann: The Penn State professor who went from stormless scientist to climate crusader


The distinguished professor of meteorology recently penned an op-ed in The New York Times titled, “If You See Something, Say Something.” The piece, which Mann said he approached a New York Times editor about writing rather than the other way around, describes Mann’s relatively newfound philosophical view on the role of scientists: “It is no longer acceptable for scientists to remain on the sidelines.”

He said in an interview that that crux of the argument is deciding what is scientists’ role and what is their responsibility.

“My view of this has evolved, in part, because of my role and the way that I’ve found myself in the center of this debate,” he said. “I’ve found myself subject to attacks, and those attacks have awakened me to the fact that scientists have to fight back. And it isn’t just to protect ourselves and to defend our integrity, but it’s because of the larger implications.”


God help us if this is what we're teaching next gen scientists.. That if you refuse to release your data -- even in a COURT PROCEEDING, that you being unfairly attacked and need to take action.

 

[flacaltenn]

Or ole Doc Hansen feeding the mush minds of the press images of "coal trains of death" and "boiling oceans" so they have "scientific cover" to make highly exaggerated documentaries and people panicking claims as tho they have any scientific validation..

ACTIVISTS is what they are -- somewhere down the list of priorities they might have trained as scientists.

Are you trying to use Penn State as some sort of ethical prop for Mann? That is not going to work with their whitewash of him and his actions. Sex offenders and liars is who they prop up and ignore the actions of.. Simply because they both brought them millions upon millions of dollars..

No Ethics... and certainly not a resume enhancement of any kind.
