Only GHGs in the lower half of the atmosphere are raising temperatures ... the GHGs in the upper half of the atmosphere work to keep solar longwave off Earth's surface, reducing temperatures ... this fact mitigates much of the man-made global warming due to carbon dioxide ...
Are you suggesting that the Earth and the Sun have similar radiative spectrums? It seems to me that there's a pretty significant temperature difference between the two and thus a pretty significant difference in their spectrums. While a few meters of CO2 at 400 ppm in our atmosphere is sufficient to absorb 100% of the IR radiated by the surface, while 22.5% of the incoming radiation from the Sun makes it through the complete thickness of our atmosphere, including reflective and opaque clouds. CO2 in the Stratosphere is not mitigating ANY significant amount of global warming
400PPM absorbs 100% IR? Are you insane?
Today I learned CO2 absorbs infrared completely in one direction, but only about 3/4 of it in the other direction.
Obviously, to save us all from
global warming climate change the horrors of American coal and SUVs, we need to turn all the CO2 molecules upside down.
That, and world socialism, of course.
