New Lab Research Shows Increasing CO2 Leads To A Negative Greenhouse Effect At The Poles
By Kenneth Richard on 2. September 2025
The evidence keeps piling up. Climate sensitivity to an increase in atmospheric CO2 is effectively zero.
Scientists Hermann Harde and Michael Schnell published a paper in 2021 entitled “Verification of the Greenhouse Effect in the Laboratory.” The study alleged to experimentally determine the atmospheric CO2 greenhouse effect not only exists, but functions in concert with physical laws.
“To our knowledge we present the first demonstration of the atmospheric greenhouse effect in a laboratory experiment, which also allows quantitative measurements under conditions as in the lower troposphere. We use an experimental set-up consisting of two plates in a closed housing, one plate in the upper position heated to 30°C, the other at the bottom and cooled to -11.4°C.”
A few years later Thorstein Seim and Borgar Olsen (2023) analyzed their experimental setup in further detail. They noted that when the CO2 is increased 500-fold, or from 0.04% (400 ppm) to 20% (200,000 ppm) in the Harde and Schnell greenhouse effect experiment the plate temperature increases by just 1.18°C, and by just 0.4°C more (1.6°C total) when the CO2 concentration reaches 100%.
