A response to climate-change deniers

I found this takeaway particularly informative: ... we can recount a few of the established physical laws and properties of CO2 that would all be wrong if human activity wasn’t the dominant driver of climate disruption today:

Conservation of energy
Conservation of mass
Quantum mechanics
Vibrational modes of CO2
Radiative transfer
Isotope ratio science for carbon-12, carbon-13, and carbon-14
Radioisotopic dating

That is a hard list to argue with.
