 My reply:

 Once again, the lie that never dies is peddled as common knowledge.

The lie is that the T^4 Stefan-Boltzmann Law can be inverted so that surface photons returned to the Earth's surface can reraise its temperature. The truth is that the temperature of the surface causes radiation that follows the S-B Law, but not vice-versa.In the case of the Earth's surface, the only heating is caused by solar radiation at 0.4-0.8 microns, raising the temperature to the range of -50C to +50C, with a wavelength range of 8-13 microns. Returning the longer wavelength radiation doesn't make the tail wag the dog and reheat the surface to the same temperature that the Sun did.

This lie is based on the bigger lie that all photons of any wavelength have the same power to raise the temperature of an absorbing material based on raw energy (Joules) alone. The truth is that a rod of temperature T cools by emitting radiation controlled by Planck's Radiation Law, whose power curve has a peak power wavelength dependent solely on T, independent of the material, meaning that its radiation can't raise the temperature of an absorbing material higher than T, regardless of the material. Thus, CO2's 15 micron radiation absorption/emission wavelength has a Planck radiation temperature of -80C, colder than dry ice, hence its radiation is indistinguishable from an iron rod cooled to -80C, which can't melt an ice cube, much less cause global warming. The U.N. IPCC lie machine tries to twist the science like a pretzel with ridiculous arguments about energy balance at the top of the atmosphere, claiming that the surface will magically increase its temperature to maintain the balance without any feedback signal or any increased radiation energy input at any temperature. It's fantasy and magic, not science. The IPCC just wishes that atmospheric CO2 can cause global warming, and jumps to save us from our anxieties by demanding trillions, with no money-back guarantee, intending the money to be used for redistribution of wealth using climate as a punch line. Since it's currently picking up steam daily, the hardened global Marxists at the top of the IPCC must be laughing all the way to the bank.
