My contribution had its ups and downs — a low point was definitely when Judge Alsup declared «your chart sucks» in response to a powerpoint slide (right) which showed an artist's impression of the Nimbus 4 satellite at the expense of a graph of how the spectrum of outgoing
long wave radiation changed in response to rising greenhouse gases between 1970 and 1997.

«Arrhenius and Chamberlain saw in this [variations in carbon dioxide] a cause of climate
changes, but the theory was never widely accepted and was abandoned when it was found that all the
long -
wave radiation absorbed by CO2 is also absorbed by water vapor.
It comes down to simple physics, the fact that greenhouse gases absorb outgoing
long wave radiation and that according to the Stephan Boltzmann equation the
change in temperature is proportional to the
radiation balance.
As
long as the outgoing longwave
radiation is n`t decreasing over the Top Of Atmosphere, all the heat uptake comes from the

wave radiation in 1970 and 1997 to see if there are
changes.
This new paradigm states that rather than the TOA (top of the atmosphere) energy balance being maintained by
changes to the outgoing
long wave radiation (which is saturated), it is mainly maintained by
changes to the outgoing short
wave radiation, i.e. albedo.
The upper atmosphere is actually cooling due to a
change in the spectra of exiting
long wave radiation and the expansion of the atmosphere due to heating.
