Climate change hysterics cannot discuss the basis for their passion without mentioning Michael Mann, who must be regarded as the face of whole climate change movement. Wikipedia makes him seem like a master of his domain:

Mann has contributed to the scientific understanding of historic climate change based on the temperature record of the past thousand years. He has pioneered techniques to find patterns in past climate change and to isolate climate signals from noisy data.

As lead author of a paper produced in 1998 with co-authors Raymond S. Bradley and Malcolm K. Hughes, Mann used advanced statistical techniques to find regional variations in a hemispherical climate reconstruction covering the past 600 years. In 1999 the same team used these techniques to produce a reconstruction over the past 1,000 years (MBH99), which was dubbed the “hockey stick graph” because of its shape. He was one of eight lead authors of the “Observed Climate Variability and Change” chapter of the Intergovernmental Panel on Climate Change (IPCC) Third Scientific Assessment Report published in 2001. A graph based on the MBH99 paper was highlighted in several parts of the report and was given wide publicity. The IPCC acknowledged that his work, along with that of the many other lead authors and review editors, contributed to the award of the 2007 Nobel Peace Prize, which was won jointly by the IPCC and Al Gore.

Mann was organizing committee chair for the National Academy of Sciences Frontiers of Science in 2003 and has received a number of honors and awards including selection by Scientific American as one of the fifty leading visionaries in science and technology in 2002. In 2012 he was inducted as a Fellow of the American Geophysical Union and was awarded the Hans Oeschger Medal of the European Geosciences Union. In 2013, he was elected a Fellow of the American Meteorological Society and awarded the status of distinguished professor in Penn State’s College of Earth and Mineral Sciences. In 2017, he was elected a Fellow of the Committee for Skeptical Inquiry.

Mann is author of more than 200 peer-reviewed and edited publications. He has also published six books: Dire Predictions: Understanding Global Warming (2008), The Hockey Stick and the Climate Wars (2012), together with co-author Tom Toles, The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy (2016) with Megan Herbert, The Tantrum That Saved the World (2018), The New Climate War (2021), and Our Fragile Moment (2023). In 2012, the European Geosciences Union described his publication record as “outstanding for a scientist of his relatively young age”. Mann is a co-founder and contributor to the climatology blog RealClimate.

All the honors and accolades prove is how politicized the scientific community is, and how progressive bias has infected so many of the world’s institutions. His so-called “hockey stick graph,” supposedly a reconstruction of past climate temperatures, was shown to be the product of dishonest statistics methodology; for example, it conveniently ignored the Medieval Warm Period that continues to bedevil the climate change narrative.

Mann has continued to wield his hockey stick like Jason Vooghies on a rampage. He calls all skepticism denial because he has an ideological agenda, and agendas bias research and make scientists untrustworthy. Like Michael Mann. Among other smoking guns related to his integrity, Mann has tried to intimidate critics who imply that he is more activist than scientist by filing defamation law suits. As one critical sources puts it, “Mann’s entire career has been one long exercise in not practicing neutrality.”

Don’t sue me, Professor: it’s just my opinion that your science is subservient to your activism and self-interest, and that you’re more interested in driving policy than finding truth.

Like a good little leftist ideologue, Mann’s commented on social media after Charlie Kirk’s death that he was “the head of Trump’s Hitler Youth”—now that’s surely a fact-based, well-researched conclusion.  Mann also said sarcastically of the assassination, “The white on white violence has gotten out of hand.” Then, of course, he deleted those posts.

Shortly after discovering, via considerable criticism of his idiotic remarks, that not everyone dwells in the Trump Hate bubble of the University of Pennsylvania where he was Penn’s Vice Provost for Climate Science, Policy, and Action, Mann announced his resignation. He risibly stated that his activism conflicts with the university’s “established institutional neutrality policy.” First, UPenn is anything but neutral, as its handling of the anti-Israel protests in 2024 proved. It is as biased and as hostile to intellectual diversity as the rest of the Ivy League. If it were genuinely neutral, it wouldn’t have employed Mann. Second, Mann’s activism conflicts with the mission, methods, traditions and ethics of science.
