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.

Observations on 400 Mio. years of paleoclimate are found to well constrain the compound universal climate role of CO2, represented by a simple formula.

Climate Etc. recently carried several insightful posts about How we fool ourselves. One of the posts – Part II: Scientific consensus building – was right on the money given our experience! The post pointed out that… ‘researcher degrees of freedom’… allows for researchers to extract statistical significance or other meaningful information out of almost any data set. Along similar lines, we offer some thoughts on how others try to fool us using statistics (aka how to lie with statistics); others being epidemiologists and government bureaucrats.

Environmental justice organizations are currently a major driver of environmental regulation in New York. A new report “The Fossil Fuel End Game, A frontline vision to retire New York City’s peaker plants by 2030” illustrates the campaign strategy they are using to shut down peaking power plants in New York City.  Unfortunately their claims are based more on emotion than fact.
