I’m a professional infrared astronomer who spent his life trying to observe space through the atmosphere’s back-radiation that the environmental activists claim is caused by CO2 and guess what? In all the bands that are responsible for back radiation in the brightness temperatures (color temperatures) related to earth’s surface temperature (between 9 microns and 13 microns for temps of 220K to 320 K) there is no absorption of radiation by CO2 at all. In all the bands between 9 and 9.5 there is mild absorption by H2O, from 9.5 to 10 microns (300 K) the atmosphere is perfectly clear except around 9.6 is a big ozone band that the warmists never mention for some reason. From 10 to 13 microns there is more absorption by H2O. Starting at 13 we get CO2 absorption but that wavelength corresponds to temperatures below even that of the south pole. Nowhere from 9 to 13 microns do we see appreciable absorption bands of CO2. This means the greenhouse effect is way over 95% caused by water vapor and probably less than 3% from CO2. I would say even ozone is more important due to the 9.6 band, but it’s so high in the atmosphere that it probably serves more to radiate heat into space than for back-radiation to the surface. The whole theory of a CO2 greenhouse effect is wrong yet the ignorant masses in academia have gone to great lengths trying to prove it with one lie and false study after another, mainly because the people pushing the global warming hoax are funded by the government who needs to report what it does to the IPCC to further their “cause”. I’m retired so I don’t need to keep my mouth shut anymore. Kept my mouth shut for 40 years, now I will tell you, not one single IR astronomer gives a rats arse about CO2. Just to let you know how stupid the global warming activists are, I’ve been to the south pole 3 times and even there, where the water vapor is under 0.2 mm precipitable, it’s still the H2O that is the main concern in our field and nobody even talks about CO2 because CO2 doesn’t absorb or radiate in the portion of the spectrum corresponding with earth’s surface temps of 220 to 320 K. Not at all. Therefore, for Earth as a black body radiator IT’S THE WATER VAPOR STUPID and not the CO2.
This is exactly what I have been reporting from running the radiative transfer model used by NCAR. The people writing these models know that global warming is BS.
