Monday Mirthiness – Mike Mann’s Hockey Team ‘will keep those papers out somehow’

by A. Watts, Aug 28, 2023 in WUWT


Remember the famous quote from the head of the UK Climate Research Unit, Dr. Phil Jones that was laid bare in ClimateGate?

…I can’t see either of these papers being in the next IPCC report. Kevin [Trenberth] and I will keep them out somehow, even if we have to redefine what the peer-review literature is!

Dr. Phil Jones – ClimateGate emails

These guys never learn. Josh writes on Twitter:

Mikey’ The Trick’ Mann at work…Another story about ‘scientists’ trying to bury papers and evidence they don’t like. It’s Climategate deja vu. Read about it here https://quadrant.org.au/opinion/doomed-planet/2023/08/how-science-is-done-these-days/

and here: The Climategate Gang Rides Again!

 

Shameless abuse of science…but then again, we know Mann has no shame, only hubris

Shock Retraction of Climate Science Paper Showing No Climate Emergency Draws Comparisons with Climategate Scandal

by C. Morrison, Aug 26, 2023 in TheDailySceptic


Shocking details of corruption and suppression in the world of peer-reviewed climate science have come to light with a recent leak of emails. They show how a determined group of activist scientists and journalists combined to secure the retraction of a paper that said a climate emergency was not supported by the available data. Science writer and economist Dr. Roger Pielke Jr. has published the startling emailsand concludes: “Shenanigans continue in climate science, with influential scientists teaming up with journalists to corrupt peer review.”

The offending paper was published in January 2022 in a Springer Nature journal and at first attracted little attention. But on September 14th the Daily Sceptic covered its main conclusions and as a result it went viral on social media with around 9,000 Twitter retweets. The story was then covered by both the Australian and Sky News Australia. The Guardian activist Graham Readfearn, along with state-owned Agence France-Presse (AFP), then launched counterattacks. AFP ‘Herald of the Anthropocene’ Marlowe Hood said the data were “grossly manipulated” and “fundamentally flawed”.

After nearly a year of lobbying, Springer Nature has retracted the popular article. In the light of concerns, the Editor-in-Chief is said to no longer have confidence in the results and conclusion reported in the paper. The authors were invited to submit an addendum but this was “not considered suitable for publication”. The leaked emails show that the addendum was sent for review to four people, and only one objected to publication.

What is shocking about this censorship is that the paper was produced by four distinguished scientists, including three professors of physics, and was heavily based on data used by the UN’s Intergovernmental Panel on Climate Change (IPCC). The lead author was Professor Gianluca Alimonti of Milan University and senior researcher of Italy’s National Institute of Nuclear Physics. Their paper reviewed the available data, but refused to be drawn into the usual mainstream narrative that catastrophises cherry-picked weather trends. During the course of their work, the scientists found that rainfall intensity and frequency was stationary in many parts of the world, and the same was true of U.S. tornadoes. Other meteorological categories including natural disasters, floods, droughts and ecosystem productivity showed no “clear positive trend of extreme events”. In addition, the scientists noted considerable growth of global plant biomass in recent decades caused by higher levels of carbon dioxide in the atmosphere.

In fact this scandal has started to attract comparison with the Climategate leaks of 2009 that also displayed considerable contempt for the peer-review process. One of the co-compilers of the Met Office’s HadCRUT global temperature database Dr. Phil Jones emailed Michael Mann, author of the infamous temperature ‘hockey stick’, stating: “I can’t see either of these papers being in the next IPCC report. Kevin and I will keep them out somehow – even if we have to redefine what the peer-reviewed literature is!”

A Brief Summary Of How ‘Global Warming’ Science Has Changed Since 1998

by K. Richard, Mar 31, 2022 in NoTricksZone


Two weeks before Dr. Michael E. Mann and colleagues published their 23 April 1998 “hockey stick” chart in Nature, a peer-reviewed journal published a paper asserting “an overwhelming majority of climate scientists” (50 out of 60) view catastrophic human-caused global warming – and even global warming itself – as an “unsupported assumption”.

At the time, satellite data indicated the lower troposphere had cooled by 0.13°C between 1979 and 1994. The Arctic had cooled by -0.88°C since the 1940s.

It was thought the IPCC had just (1995) perpetrated a “disturbing corruption of the peer-review process” in manipulating the conclusions of scientists to support favored government policies.

Internal Multidecadal and Interdecadal Climate Oscillations: Absence of Evidence Is No Evidence of Absence

by G. Müller-Plath, Nov 29, 2020 in WUWT


Introduction

The present paper contributes a critical commentary on the recent finding by Mann, M. E., Steinman, B. A. and Miller, S. K (2020). Absence of internal multidecadal and interdecadal oscillations in climate model simulations. Nat. Commun. 11, 1–9.

Climate oscillations are recurring large-scale fluctuations in the surface temperatures of the oceans in connection with the atmosphere. This commentary focuses on the Pacific Decadal Oscillation (PDO, interdecadal timescale) and the Atlantic Multidecadal Oscillation (AMO, multidecadal timescale), which have been regarded as intrinsic climate drivers on the adjacent continents in numerous studies based on observations and paleoclimate reconstructions (Henley, 2017O’Reilly et al., 2017). In a recent paper, Michael E. Mann and colleagues (Mann et al., 2020, hereafter M20) fail to find a PDO signal in global measured and modeled temperatures that is statistically different from noise. They further propose that the significant AMO-like signal is mainly due to anthropogenic aerosols in the 20th century, and to statistical artifacts before. Therefore they doubt the intrinsic nature of the two oscillations. The present paper shows that M20’s results are largely artifacts themselves with issues ranging from using inadequate data and referencing improper literature on anthropogenic aerosols with regards to the AMO to inappropriately interpreting the results with regards to the PDO.
