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.
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 significantly greater than the observations. This is a test result from which we can say the models failed, and thus one shouldn’t depend on model output to characterize the future climate.
Grégoire Canlorbe: You are notably known for your involvement—along with Roy Spencer—in devising the first successful satellite temperature record. It turns out that beforehand you had already built your “first climate datasets” at the age of twelve, “using a mechanical pencil, graph paper, and long-division (no calculators back then.)” Could you tell us more about this life of invention?
John Christy: I was fascinated with the weather conditions around my home in the San Joaquin Valley of California (a desert basically) and the contrast with the climate of the Sierra Nevada Mountains immediately to the East. I was curious as to why some years were wet, others dry… why the Sierras had more precipitation and why the snow levels varied so much. I was the first high school student in California to write a simple program to predict the weather and to calculate the snow level in the mountains. These were very crude, statistical models in 1968, written for computers that were far less sophisticated than today’s cell phone. But, they introduced me to computer coding and to the power that was required to study. That was over 50 years ago.

“The agreement of the Paris COP 21 was not signed to save the planet and to prevent us from roasting due to an imaginary temperature increase of +2°C. Behind all that masquerade is hidden, as always, the ugly face of power, greed, and profit. All the industrialists who are in favor of that commitment, which will ruin Europe and immensely impoverish its citizens, do so for the good reason they find in it a huge and easy source of income. As for NGOs, when they are not simply motivated by greed, their motive consists in a resolutely Malthusian ideology. Their object is to return the world to a very small population, on the order of a few hundred million people. To do so, they impoverish the world, remove the power of fossil fuel energies, and thus ensure that the number of deaths increases.”
Professor István Markó (1956 – 2017)
The eminent Davos man that is Emmanuel Macron does not only profess his faith in cosmopolitanism—namely, the refusal of sovereign nations, as well as of genetic and cultural differences (between men), and of moral boundaries (in the human heart).[i] Climate activism, which fights for the reduction of the human emissions of carbon dioxide—in the name of the warming supposedly caused by those same emissions—occupies an essential place in the creed of the current French President, who does not hesitate to challenge Trump on this ground. Be it climate activism or cosmopolitanism, Macron’s conceptions lie in the lineage of the global superclass whose emissary he is.

Richard Siegmund Lindzen is an American atmospheric physicist known for his work in the dynamics of the atmosphere, atmospheric tides, and ozone photochemistry. He has published more than 200 scientific papers and books. From 1983 until his retirement in 2013, he was Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology. He was a lead author of Chapter 7, “Physical Climate Processes and Feedbacks,” of the Intergovernmental Panel on Climate Change’s Third Assessment Report on climate change. He has criticized the scientific consensus about climate change and what he has called “climate alarmism.”
A short while ago, Prof. Lindzen had a conversation with Mr. Grégoire Canlorbe, who interviewed him on behalf on the French Association des climato-réalistes—the only climate-realist organization in France.
Grégoire Canlorbe: Your early work dealt with ozone photochemistry, the aerodynamics of the middle atmosphere, the theory of atmospheric tides, and planetary waves. How do you present to the layman the several scientific discoveries you were responsible for in these areas?
Richard Lindzen: My work is mostly about ‘explaining’ rather than ‘discovering’, and I doubt that my achievements would mean much to laymen. With respect to my early work, I provided the explanation for the Quasi-biennial Oscillation of the tropical stratosphere. This phenomenon refers to the fact that the wind between 16 and about 30 km in the tropics blows from east to west for approximately a year, and then reverses and blows from west to east for about another year.
