Although a game played on a relatively tiny stage, ClimateBall™ points to fundamental processes, which across the vastly larger global public stage and involving billions of meme transactions annually, have caused the emergence of a cultural belief-system based upon the narrative of ‘certain catastrophic climate-change’.

“The field of Sun-climate relations . . . in recent years has been corrupted by unwelcome political and financial influence as climate change sceptics have seized upon putative solar effects as an excuse for inaction on anthropogenic warming” – Lockwood (2012)

“We argue that the Sun/climate debate is one of these issues where the IPCC’s “consensus” statements were prematurely achieved through the suppression of dissenting scientific opinions.” –  Connolly et al. (2021)

One day after the IPCC released the AR6 I published a paper in Climate Dynamics showing that their “Optimal Fingerprinting” methodology on which they have long relied for attributing climate change to greenhouse gases is seriously flawed and its results are unreliable and largely meaningless. Some of the errors would be obvious to anyone trained in regression analysis, and the fact that they went unnoticed for 20 years despite the method being so heavily used does not reflect well on climatology as an empirical discipline.

Two new peer-reviewed papers from independent teams confirm that climate models overstate atmospheric warming and the problem has gotten worse over time, not better. The papers are Mitchell et al. (2020) “The vertical profile of recent tropical temperature trends: Persistent model biases in the context of internal variability”  Environmental Research Letters, and McKitrick and Christy (2020) “Pervasive warming bias in CMIP6 tropospheric layers” Earth and Space Science. John and I didn’t know about the Mitchell team’s work until after their paper came out, and they likewise didn’t know about ours.

Heat waves are the new polar bears, stoking alarm about climate change.  Climate scientists addressing this in the media are using misleading and/or inadequate approaches.  How should we approach assessing whether and how much manmade global warming has contributed to recent record breaking  temperatures?  Read on for some outside-the-box thinking on this.

Earlier this year, Eric Kaufmann of the University of London published a remarkably detailed and comprehensive study of bias in academia, “Academic Freedom in Crisis: Punishment, Political Discrimination, and Self-Censorship.” Kaufmann’s writing is a product of California’s Center for the Study of Partisanship and Ideology, a small think-tank set up to do research that is forbidden in today’s academy. His finding of rampant left-sided political bias in publication, employment, and promotion in the Academy — and discrimination against anyone right-of-center — qualifies as forbidden scholarship.

Simple models are formulated to identify the essentials of the natural climate variabilities, concentrating on the readily observable and simplest description. The results will be presented in a series of five articles. This first part shows an attempt to determine the climate role of CO2 from the past. Observations on 400 Mio. years of paleoclimate are found to well constrain the compound universal climate role of CO2, represented by a simple formula.
