but this article isn’t so useful in countering the alarmism about CO2 and climate.
I disagree.
The article explained that C02 is even less likely to function as a barrier to Infra Red, IR. Basically if this experiment did not show significant increase in temperature, there is no way C02 is going to. That trapping IR with C02 is like trying to capture mice with a chain linked fence. I think rather simple to explain to others.
Especially leftists rats. ; )
Well, that mice-through-a-chain-linked-fence comparison is simple, but it doesn’t ring so true. The so-called greenhouse gases absorbed over 94% of the outgoing infrared radiation from Earth’s surface before the industrial age, and that figure is probably a tiny bit bigger today. But that’s not the whole story either. When a so-called greenhouse gas molecule absorbs an IR photon, it reemits IR. The new emissions go in random directions, some go out towards space and some go down towards Earth. On their way, they too may be absorbed by another greenhouse gas molecule, or maybe they’ll hit a particle of black soot or something and transfer some or all of their energy to the particle. The greenhouse gas absorptions and remissions occur at the speed of light. It’s a very busy atmosphere. A lot of the infrared emitted from Earth’s surface does make it out to space, but the notion that relatively low ppm value makes these greenhouse molecules as easy to avoid (for IR) as a chain link fence is for a mouse doesn’t do justice to how many inches of atmosphere these photons have to travel through.
