“Had read somewhere that CO2 being heavier than air sank to ground or sealevel, hence it being taken in by plants and the oceans. This “sinking” in fact made CO2 impossible as a Greenhouse gas.”
Yes, the molecular weight of CO2 is greater than that of air, a mixture of mostly nitrogen and oxygen. But CO2’s behavior in air is to disperse, or ‘dissolve’ into the air as a gas. CO2 only ‘sinks’ in air to the extent it remains ‘together’, as in the example of the contents of a CO2 fire extinguisher discharged at the base of a fire. As a gas, CO2 will thoroughly mix with the atmosphere, not sink therefrom to the oceans or plant life. It will be absorbed by plants or dissolve in water through contact with the atmosphere.
Not wanting or actually being able to necessarily argue the technical point, would seem unless they cease being individual molecules of CO2, to which the chemical mixture would no longer be oxygen, nitrogen and CO2, but some other gaseous compound what is the reaction catalyst?
The Warmers do not refer to “a mixture including CO2” rather only CO2.
If individual pure molecules not reacted and remaining pure CO2 but dispersed as you say and being heavier will surely eventually settle out displacing the lighter molecules at the lowest level. Am I misunderstanding this?
