For about 33 years, many of us have been battling against climate hysteria. We have correctly noted
The exaggerated sensitivity,
The role of other processes and natural internal variability,
The inconsistency with the paleoclimate record,
The absence of evidence for increased extremes, droughts, floods, wild-fires, and so on.
We have also pointed out the very real benefits of CO2 and even of modest warming. And, as concerns government policies, we have been pretty ineffective. Indeed our efforts have done little other than to show (incorrectly) that we take the threat scenario seriously. In this talk, I want to make a tentative analysis of our failure.
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”
