Atmospheric concentrations of CO2 produce a measurable greenhouse effect
Atmospheric concentrations of carbon dioxide produce a measurable greenhouse effect, a foundational principle supported by direct absorption measurements and climate models.
The claim is a well-established empirical fact in climate science. Multiple papers (0, 1, 2, 10) directly discuss the radiative forcing, absorption properties, and greenhouse warming contributions of atmospheric carbon dioxide, providing strong and consistent support without refutation.

Calculations of radiative forcing explicitly quantify the warming effect of carbon dioxide.

Laboratory absorption measurements demonstrate that atmospheric CO2 absorbs laser radiation, underpinning the greenhouse mechanism.

Atmospheric CO2 and added greenhouse forcing are modeled to artificially warm planets like Mars by producing a greenhouse effect.
