Re: A rich man...
yeah, well it's understanding the mechanism by which a greenhouse gas would alter temperatures on the planet that is the core of this.
Greenhouse gasses [of which there are several] trap heat that would OTHERWISE escape out into space, acting like a blanket (i.e. keep the heat on the planet). Some of them have opposite effect during the day (like water). ALL of them absorb infrared radiation, and those energies absorbed would then (effectively) 'warm the planet' through various means (convection, radiation).
An object that is above absolute zero emits radiation to cool down to (eventually) absolute zero. The sun keeps earth from doing that completely, but on the 'dark side' of the planet, it emits "black body radiation", in the form of photons. The emitted photons have energy levels that are well known. The distribution of energy is asymptotic, and theoretically includes ALL energies below the one corresponding to the temperature, but being practical, it's a small band. So yeah, at 20C, you'll see energies corresponding to something that CO2 *might* absorb (like the energy for -50C), but it will be so FEW photons you can consider it to be "effectively zero" - like a limit in calculus.
Understanding that - examine the physical properties of CO2, for REAL, and NOT just because a bunch of self-proclaimed (paid by those with a political agenda) "climate scientists" "concur" on something.
Someone already mentioned 'flat earth'. A bunch of "scientists" used to CONCUR on *THAT* falsehood, too... for MANY CENTURIES!
Here's a thought: if a compost pile produces methane, a REAL greenhouse gas, how come the warmists aren't going after THOSE? It's a fair bet that a LOT of environmentally-conscious people do composting...
Additionally, at higher CO2 levels [like cloud seeding] you should see MORE RAIN. That may have a much LARGER effect than any 'greenhouse gas' might have, and in the OPPOSITE direction! Thing is, rain ALSO depletes the CO2, putting it into the dirt, lakes, rivers, and the ocean [where it eventually precipitates out as MgCO3 and CaCO3]. It's like when there's a forest fire in California, and the smoke gets blown over the ocean, expect it to come circling back as a major rainstorm because the smoke particles form 'nuclei of condensation' for the water vapor [again, like cloud seeding].
to (as I remember) quote C.S. Lewis from one of his books: "What DO they teach in these schools?"
