These are old experiments dating to the mid 1800's.http://www.searchanddiscovery.com/pdfz/documents/2011/70092sorenson/ndx_sorenson.pdf.htmlhttp://aip.org/history/climate/co2.htmTyndall, John (1861). "On the Absorption and Radiation of Heat by Gases and Vapours..." Philosophical Magazine ser. 4, 22: 169-94, 273-85.Tyndall set out to find whether there was in fact any gas in the atmosphere that could trap heat rays. In 1859, his careful laboratory work identified several gases that did just that. The most important was simple water vapor (H2O). Also effective was carbon dioxide (CO2), although in the atmosphere the gas is only a few parts in ten thousand. ...Yes I know that you don't believe in backscatter. The second law refers to heat not energy. That is easy to see by a simple example. Thermal energy in a solid metal is vibratory energy and it's atoms stay put. Thermal energy in a gas is largely free kinetic motion. If a hot solid is in a closed system with a colder gas, the gas spontaneously bombards the surface of the solid because of kinetic energy of it's free moving atoms.That is a very clear and obvious example of energy from a colder substance spontaneously impinging on a hotter substance. Of course more energy from the hotter solid is transferred to the colder gas than the other way around. So the second law is preserved as a spontaneous one way flow of heat even though there is a two way flow of (kinetic) energy.
