Let's use this handy calculator to create our own test of the "greenhouse effect," assuming an Al Gore apocalyptic scenario of the earth's atmosphere [currently 0.0389% CO2] having a greenhouse gas concentration so high that the atmosphere becomes a perfect "back-radiator" of heat from the earth and doesn't let any heat at all escape to space, but still lets the solar energy in. We use the default values for solar input of 1367 Wm-2, albedo of 31%, and set back radiation at 100% (.999) rather than the default 39.7%, and observe that the average temperature of the earth rises to 1428.05°K, or 2111°F. Now 2111°F is pretty hot, in fact aluminum melts at 1220°F, magnesium at 1200°F, and steel at 2600°F. Amazing that the "greenhouse gases" can accomplish this while ideal laboratory conditions cannot. The maximum laboratory temperatures that could be obtained with a laboratory blackbody which absorbs nearly all incoming radiation is given by the Stefan-Boltzmann equation, which tells us the maximum temperature with the same inputs would be 359.11°K or 186.72°F. Hmmm, that's less by a factor of 11 than what greenhouse gases can supposedly achieve according to U Mass. The greenhouse hypothesis makes a self-contradictory claim that back-radiation causes a body to EXCEED the blackbody limit, even though a laboratory blackbody EPITOMIZES the effect of back-radiation.
I'm pretty sure that if you tried this at home, with ten 100 Watt light bulbs mounted on a mirror 1 meter square to provide 1000 Wm-2 heat input (analogous to solar input of 1367 Wm-2 minus 31% albedo = 943 Wm-2), hung this contraption a bit above the earth and facing downwards, that the earth's surface temperature would rise less than to 2111°F. Or just stand up and point a 1000W hair blower down at your foot; I did and my foot is fine. I'm also pretty sure that if you did the Siddons mirror example, you would not find that the mirror makes the spot on the wall brighter by a factor of 11 (actual amount is zero).
Why such an absurd result from UMass? It's because greenhouse theory ignores the conservation of energy demanded by the 1st law of thermodynamics by assuming our atmosphere is one giant perpetual heat engine "back radiating" heat energy from colder "greenhouse gases" to the earth, causing it to warm up far beyond the solar input, and rinse, cycle, repeat...global calamity. It also ignores the 2nd law of thermodynamics by assuming a cold body ('greenhouse gases") can warm a hot body (earth).
These errors in basic 19th century physics continue to be promulgated at U Mass and indeed most everywhere else. The "beauty" of the greenhouse theory is that it has two major fudge factors to play with: albedo (which is poorly understood and difficult to measure) and unphysical % "back radiation." By assigning arbitrary values to these two fudge factors one can program a computer model that looks like it agrees with global temperatures and thus bamboozle most scientists and the public, while hiding a perpetual motion machine (heat pump) inside. These science fiction theatrics do not warrant the waste of billion$ to enrich the likes of Al Gore & George Soros to the detriment of the rest of humanity.
For papers reflecting the actual physics of the atmosphere, see the Gerlich & Tscheuschner papers and this non-technical summary. See also the Chilingar et al paper.
Maybe someday folks will discover why the Cascading Oven from former atmospheric scientist Jim Peden never sells:
