Laurent Alexandre is a French surgeon-urologist, essayist, and entrepreneur. The founder of the Doctissimo website, he is interested in the transhumanist movement and in the upheavals that humanity could experience, along with the progress of science in the field of biotechnology. His latest book is L’IA va-t-elle aussi tuer la démocratie [Will AI kill democracy as well]?

Grégoire Canlorbe: It should be remembered that Nietzsche saw in birth control, as well as in the non-assistance of weak elements (in terms of physical or mental abilities) in our society, an unavoidable aspect of the superhuman culture which he was calling for. As a supposed transhumanist, do you regret the collapse of the eugenic movement in the 1950s?

Laurent Alexandre: I do not believe that the 1950s are a period of decline of eugenics, they are rather a period of mutation of eugenics. When Julien Huxley invents the word “transhumanism” in 1957, it is for the purpose of creating left-wing eugenics… namely egalitarian eugenics. The 1950s did not see eugenics receding after the horrors of Nazism: they saw right-wing eugenics mutate into a leftist eugenics, dubbed “transhumanism” by Huxley.

Grégoire Canlorbe: The alleged responsibility of human carbon emissions for contemporary warming is a subject that is conducive to raising the temperature in debates. Could you remind us of the main lines of your Promethean (or Faustian) reassessment of climate policy: namely a reassessment that does not deny the need to mitigate the greenhouse effect supposedly linked to CO2 emissions, but which attempts to conciliate climate action, the industrial and cognitive domination of nature, and materialistic enjoyment?

Laurent Alexandre: Controlling CO2 emissions is going to be incredibly complicated. One is going to spend several very difficult decades. And if indeed, as I believe, there is a link between CO2 and climate, we will not be able to reduce CO2 emissions before 2050. We will have climate concerns probably until the end of the century.

First of all, collapsologists overestimate the social body’s acceptance of a CO2 reduction policy. We have seen what means a tiny drop in the purchasing power of Yellow Vests to fight against the greenhouse effect: one imagines what would give a drop of 30 to 40% of the purchasing power of the lower classes. One would have a real revolution, which would probably be a far-right revolution rather than an extreme-left one in the current context. A degrowth policy will therefore be very hardly accepted… and one can see that all the polls show that the priority of the French is the purchasing power before the ecological transition.

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.
