A newly published paper, titled “Evaluating the Performance of Past Climate Model Projections,” mistakenly claims climate models have been remarkably accurate predicting future temperatures. The paper is receiving substantial media attention, but we urge caution before blindly accepting the paper’s assertions.
___________ “Global warming is not a purely scientific issue any more,” he said. “It has repercussions for society. It has also taken on a moralistic, almost religious quality. If you believe what everyone believes, you are a good person. If you don’t, you are a bad person. Who wants to be a sinner?” ___________

The U.S. auto industry and regulators in California and Washington appear
deadlocked over stiff Obama-era fuel-efficiency standards that automakers oppose and the Trump administration have vowed to roll back – an initiative that has environmental activists up in arms.
John Raymond Christy is a climate scientist at the University of Alabama in Huntsville (UAH) whose chief interests are satellite remote sensing of global climate and global climate change. In February 2019 he was named as a member of the EPA Science Advisory Board.

In May 2019 he was interviewed by Grégoire Canlorbe for Association des climato-réalistes, the only climate-realist association in France. The conversation was first published in the French journal Valeurs Actuelles (in a French edited version), and on Friends of Science (in the original English version).
Grégoire Canlorbe: You have been at pains to show that climate models are over-predicting warming by roughly a factor of two. Could you come back to this alleged falsification?
John Christy: We should be applying the scientific method to claims scientists (and others) are making about the climate. In this case I downloaded the output from 102 climate model simulations used by the IPCC and compared the tropospheric temperature since 1979 between the models and several observational datasets, including the satellite dataset we generate. The models on average were warming the atmosphere at a rate Continue reading “A conversation with John Christy, for Association des climato-réalistes”
It’s been long known that NASA1 GISS2 has been going through its historical temperature data archives and erasing old temperature measurements and replacing them with new, made up figures without any real legitimate reason.
This practice has led to the formation of new datasets called “adjusted” data, with the old datasets being called “V3 unadjusted”. The problem for global warming activists, however, was that when anyone looks at the old “V3 unadjusted” – i.e. untampered data – they often found a downward linear temperature trend. Such negative trends of course are an embarrassment for global warming alarmists, who have been claiming the planet is warming up rapidly.

The original article is available here. This article should be of particular interest to our forum in light of the recent discussions regarding progress, or lack thereof, in getting the skeptical point of view out to the general populace. One might conclude from this article that the skeptical community with help from climate economics may be seeing more success in changing minds than we might have thought. Ed.]
From Alberta to Australia, from Finland to France and beyond, voters are increasingly showing their displeasure with expensive energy policies imposed by politicians in an inane effort to fight purported human-caused climate change.
Skepticism about whether humans are causing dangerous climate change has always been higher in the United States than in most industrialized countries. As a result, governments in Europe, Canada, and in other developed countries are much farther along the energy-rationing path that cutting carbon dioxide emissions requires than the United States is. Residents in these countries have begun to revolt against the higher energy costs they suffer under as a result of ever-increasing taxes on fossil fuels Continue reading “Climate Politics Abroad Are Turning Decidedly Skeptical”
