Non-greenhouse gases like O2 and N2 (air) absorb radiation “almost to the same degree” as CO2 does in outdoor experiments, which is “proof that the greenhouse theory cannot be true.”  – Allmendinger, 2023

A principal reason why CO2 is regarded as a special gas, the “control knob” of the globe’s surface temperature, is that it is thought to be a potent greenhouse gas that absorbs thermal radiation.

But a real-world outdoor experiment (Allmendinger, 2023) involving containers heated by sunlight reveals there is no equilibrium temperature or heating rate difference when filling a container with 100% CO2 vs. 100% argon (Ar), a non-greenhouse gas. That’s because noble gases (like Ar) absorb radiation too.

Furthermore, there is only a modest (<5%) temperature differential when the container is filled with only air (21% O2, 78% N2, 0.042% CO2) vs. a 100% (1,000,000 ppm) CO2-filled container. Like Ar, O2 and N2 are regarded as non-greenhouse gases, but they nonetheless absorb thermal radiation too.

The molecular weight of the gases, and the consequent variation in convective heat transfer, is what primarily determines the slight (<5%) temperature differential (Wagoner et al., 2010). Argon and CO2 have similar (heavier) molecular densities, allowing them to more effectively reduce heat loss, whereas as O2 and N2 are lighter gases. The radiative heat transfer properties of non-greenhouse gases vs. greenhouse gases are thus not temperature-determinative in real-world experiments.

Dr. Allmendinger conducted another outdoor experiment demonstrating the temperature gradient at different altitudes above the Earth’s surface is not determined by the radiative properties of greenhouse gases vs. non-greenhouse gases either. While the atmosphere does thermally radiate back to the Earth’s surface, “this radiation has nothing to do with trace gases such as CO2,” but instead it “depends on the atmospheric pressure which diminishes at higher altitudes.”

Thus, it can be empirically demonstrated that “trace gases such as CO2 don’t have any influence on the behavior of the atmosphere, and thus on climate.”
