BTW, since it gets chilly in the desert at night, why isn't the CO2 back radiation warming it up?but you can't provide any evidence that happens. Why is that so difficult for someone who appears to have some smarts about you? There is zero evidence that a back radiation exists in the atmosphere. ZERO. Otherwise it would have been posted by now.I agree that is the crux of the problem with global warming. To simply say that back radiation doesn't exist and therefore climate models are fraudulent, as SSDD does, is first of all a misunderstanding of the 2nd law of thermo. Secondly, as you say there are plenty of other modeling difficulties that would still remain if he did believe in back radiation.The problem with the atmosphere is that there are so many other variables to consider.
Even the example of the iron is problematic. If you put it in space, would the plate be warmer or cooler than on the surface? Conduction and convection are much more efficient at removing heat. Would loss of environmental input make up for the other pathways at equilibrium? I don't know for sure.
The hot iron was a simple example of feeling radiation going downward, but I agree radiation alone is totally inadequate to cover the full dynamics of the iron, let alone the atmosphere.
but you can't provide any evidence that happens.
You don't believe all matter above 0K radiates in all directions all the time?
There is zero evidence that a back radiation exists in the atmosphere.
Why can it get chilly in the desert at night?
Good point....there is as much CO2 in the air in the desert as their is in more humid areas...and when you remove the water vapor, you can see just how effective CO2 is at warming....that is...it isn't because it can't...
