Nearly every academic in the country believes that Venus is hot because of the large amount of CO2 in their atmosphere, which they say is “trapping the Sun’s heat.”
It is trivial to demonstrate that this theory is mindless nonsense.
The lapse rate on Earth is nearly the same as it is on Venus, despite the fact that the Venusian atmosphere has 95% GHG, and Earth’s atmosphere has less than 3% GHG.
Venus lapse rate is slightly higher than Earth, because CO2 is more dense than N2 or O2. Thus the atmospheric pressure increases at a higher rate as you descend through the atmosphere.
If GHG’s controlled the lapse rate on Earth, then humid days would have much higher lapse rates than dry days. In fact, we see the exact opposite. Humid days have slightly lower lapse rates than dry days, because H2O is less dense than N2 or O2. GHG’s have very little control of the temperature.
If GHG’s controlled the lapse rate on Earth, then the lapse rate would decrease with altitude, because there are more GHG’s near the surface. This doesn’t happen.
Venus surface receives very little sunlight. They go for months at a time in total darkness. yet the temperature doesn’t drop. How can anyone be stupid enough to believe that Venus is hot because of trapped sunlight?
Venus is hot because it has a very tall, high pressure troposphere. At 1000 mb in the Venusian atmosphere, temperatures are similar to Earth’s surface, despite a very different chemical makeup of the atmosphere.
The bottom of the Grand Canyon is hot because of high atmospheric pressure. The top of the Grand Canyon is cold because of low atmospheric pressure.
The combined IQ of academia on this subject is close to zero. Complete flaming idiots.
