Put Up or Shut Up, Indeed
Dr. Roy Spencer, another in the Church of The Lukewarm Greenhouse Effect, tells deniers of that effect to "put up or shut up", to which I have responded:
After all this time, everyone still clings to their own pet statement of a "greenhouse effect", when the only valid statement--promulgated to the public for over 20 years -- is "an increase in global mean surface temperature with increasing atmospheric carbon dioxide".
But a simple comparison of temperatures in the atmospheres of Venus and Earth, at points of equal pressure over the range of Earth tropospheric pressures, shows that the Venus/Earth temperature ratio is a constant (there is no ADDED temperature on Venus due to its much higher atmospheric carbon dioxide concentration), and in fact a constant that is PRECISELY explained by Venus's smaller distance from the Sun, and nothing else (except within Venus's cloud layer, between about 650 and 200 mb pressure, where the Venus temp. is about 5K LOWER--in other words, a minor ADDITIVE effect within the clouds themselves--than that calculated, simply, from the Standard Atmosphere model here on Earth and the ratio of solar distances of the two planets).
"Lukewarmers" like Spencer and Watts are stymied by their unswerving belief in the radiative transfer theory. My Venus/Earth demonstration of the absolute absence of a greenhouse effect--as I define it, and as it is sold to the public--implies the radiative transfer theory is also wrong, physically; but I am not about arguing theories, and I don't feel any need to put forward a better one to replace theirs. I only insist that the Venus/Earth temperature ratio is the definitive evidence that denies their theory. Contrary to Spencer's insistence heretofore, the onus is on defenders of the consensus greenhouse theory to demonstrate quantitatively, that the observed Venus/Earth constant temperature ratio--needing nothing but the ratio of their solar distances to explain--arises naturally from their theories. I have already demanded you put up or shut up, many times over the last two and a half years. Instead, you go on about how you "observe" the greenhouse effect (but not the one that counts), without confronting the definitive evidence that denies that effect's existence (specifically, in the atmospheres of Venus and Earth). How lukewarmers can fight against the alarmists, and often give evidence that the global warming "greenhouse effect" must be very small, nevertheless are dogmatically set against admitting that effect is zero, is all that separates you from the "Slayers", in the end. (And no, I am not one of them; they like to say carbon dioxide is a coolant, but my Venus/Earth comparison says that is no more correct than that it is a heater. It is a "heat lubricant", whose increase only speeds up heat transfer--by radiation--within the atmosphere, without changing either the lapse rate or the surface mean temperature; it neither traps nor slows down heat).
