Global Warming on Free Republic
The math in this article is very interesting, but I do have a question - for anyone.
I wonder if the fact that the Earth’s atmosphere at 1000 MB is bordered on one side by land and sea changes the temperature equation?
On Venus, that same pressure is bordered on two sides by gas.

Our problem must be the cow-farts —
“absolute proof”
“NO WAY”
Sounds more like the rants of a religious fanatic than science.
This is nonsense. Go back and learn something about science.
CO2 constitutes 0.039% of the Earth’s atmosphere. Not 10%, not 1%, not 0.1%; just 0.039%. About 4 parts per 1,000. Climate change alarmists have never explained how a gas that constitutes such an infinitesimally small percentage of the atmosphere could have oh so powerful an effect on climate.
“there is almost NO difference between Earth and Venus when it comes to atmospheric temperature, even though Venus has an atmosphere composed almost entirely of CO2. ... The temperature of Venus at 1000 millibars is 339 Kelvin (66 C).” (1000 millibars = temp at the surface).
There is no way that Venus has a balmy surface temp of 65.8 degrees Fahrenheit. This guy must have done his “math” in the 1950s when 65 degrees at surface was believed to be correct.
Kelvin measures temps in relation to absolute zero, while Celsius measures in relation to the freezing point of water.
His “math” is BS:
“There are many geophysical similarities between Venus and the Earth. Average temperature is not one of them. Where the Earth has an average surface temperature of 14 degrees Celsius, the average temperature of Venus is 460 degrees Celsius. That is 410 degrees hotter than the hottest deserts on our planet.
The temperature on Venus does not vary like it does on our home world. It is 460 degrees day or night, at the poles or at the equator.”
(733.15 degrees Kelvin = 460 degrees Celsius, or 860 degrees Fahrenheit).

“And so today we have a carbon dioxide atmosphere on Venus which is 92 times more dense than Earth’s atmosphere at the surface.”

Proximity to the Sun does not account for the radical differences in surface temperatures. Nor does the Earth have surface pressures anywhere near that of Venus, being the equivalent to that found a half mile beneath the ocean. This guy makes some simplistic adjustments to various known numbers, then composes some formula out of his head to produce the result he desires.
