Everytime I think this guy has reached the lowest depth of stupidity, he proves me wrong by reaching lower. The CO2 in Venus’ atmosphere did not simply cause the temperatures to reach 870 degrees. There were a lot of factors, but basically it appears that Venus got locked in a feedback loop of sorts. Rising temperatures caused by the Sun and lack of sufficient atmospheric protection caused the rock in Venus’ crust to release CO2, exactly as we see on Earth. However, unlike Earth, which has a biosphere to compensate and regulate CO2, Venus had no easy way to deal with the increased CO2 until the solar heating subsided and the atmospheric CO2 was re-absorbed by the crust. Therefore it became a deadly cycle leading to greenhouse heating, more CO2 released, more greenhouse heating, etc.
The key difference is life! Without life on Earth, Earth could get locked in a cycle like Venus, and would be unable to support life. What does Al Gore think caused the CO2 on Venus in the first place? Venusians driving SUV’s?!?
Excellent. My instructor years ago would compliment you.
