The use of the phrase "global warming" is unfortunate -
"a runaway greenhouse effect" would more succinctly describe the interesting thing about the temperature of Venus.
Venus is 100's of degrees hotter than would be predicted solely by its distance from the sun. This is caused by its dense atmosphere of over 90% CO2. This was discovered in the 1970s (Carl Sagan is a famous contributor) and is not controversial.

Interestingly, it is thought that it was once much cooler, but that the positive feedback produced by increased temperatures from atmospheric CO2 caused more CO2 to be released from surface minerals, accelerating the process.

Why doesn't Earth's C02 escape through the hole in the Ozone Layer?

"but that the positive feedback produced by increased temperatures from atmospheric CO2 caused more CO2 to be released from surface minerals, accelerating the process."

AND THE POINT?

Actually, it is supposedly hotter on the surface of Venus (400-740k) than on Mercury (90-700k).

Kinda makes you wonder what you could do with Venus if you could introduce some kind of fungus/bacteria into its upper atomsphere that would help re-entrain some of that carbon.

I appreciate you bringing some actual science discussion to this thread.

I initiated it as a light-hearted jab at the author's choice of politically charged terminology.

However, its good to see someone actually provide the type of valuable information that is usually missing in these MSM articles.

Are there any realistic connection or lessons that can be derived about Earth from studying Venus' environment?
