As Gilbert Harding would have said in times gone by "it all depends on
what you mean by the Greenhouse effect"
The basic idea that solar radiation comes to the ground by light and
infra red radiation and is transmitted at a longer wavelength - that
part is very well understood. So is the propensity of particular
molecules to absorb radiation of particular wavelengths. Perhaps less so
are the exact constituents of the upper atmosphere where all this
absorption goes on.
