My reply:

Christy's understanding of thermal physics is at the 5th grader level. He still thinks that CO2's 15 micron radiation can affect Earth temperature. The truth is that only the surfaces of the Sun and Earth are black body radiators that absorb and emit photons of all wavelengths, while Earth's atmosphere can never be a black body, hence it can't stop the surface from cooling each day to rid itself of solar heat, much less stop and reverse it. Greenhouse gases are a pure fake physics hoax. Christy's career as a professor of atmospheric science is a waste from the starting gate.
