Yes, it is a calculated result and not a measured result. Then again, a direct calculation is better than a computer simulation any day… so I’d say it’s over to the Nintendo Kids to work out a comeback.
The bottom line is that adding a bit of CO2 to some damp air makes the whole works cooler, not warmer.

It’s technical, but not too hard to follow if you’ve had some chemistry and physics.
Bottom line is that the prior assumption of warming from CO2 is wrong.
How you say “Ooops”…
I think someone needs to learn that a mixture of things is different from them in isolation. Like alloys.
Maybe someone needs to tell the trees. This video was one I reached after following a link from Scarlet Pumpernickel. In it, Freeman Dyson basically says ~” Real observations matter, we are presently doing them badly, and when you do measure, you find it’s all about the trees, if you don’t understand them, the computer models are useless’.
I’ve moved Scarlet Pumpernickels comment from the Ozone Hole thread to here (it’s the first comment below with part 2 of this video in it). While that part does talk about ozone loss as the stratosphere cools, I think if fits better with this new posting. In it, Freeman Dyson points out that CO2 causes the Stratosphere to cool. That was a loose end for me in the posting about tropospheric convection. I knew that the upper atmosphere cooled (thermosphere / mesosphere) when solar UV output dropped. I knew that the troposphere had convective dominance. That still left the Stratosphere in the middle. This completes the set. So now we have:
Sun takes a break and UV plunges.
Lower UV means a colder mesosphere and thermosphere, and lower ozone in the Stratosphere.
Lower Ozone means the 11 micron IR window “opens”.
Stratosphere cools as well (and the whole upper atmosphere gets more compressed) so heat transport will be more effective.
All the cooling cuts water vapor as it makes rain / freezes into noctilucent clouds.
Troposphere convects a bit more rapidly (the “gustier” and “blustery” quality I’ve noted) and we have a net large increase in heat flow out, or cooling.
CO2 cools damp air. CO2 cools the stratosphere. The sun cools the stratosphere, mesosphere, and troposphere when the UV level drops
(and thus must also warm them when UV rises…)
All observable and testable / measurable (or already observed in most cases).
The Sun “did it”:
That plants dominate the CO2 cycle:
Rain and the troposphere:
I think this whole picture is starting to come together nicely.
