Yeah maybe if our atmosphere was as thick as Venus's the CO2 might have that sort of effect.
"Increased CO2 has no effect, because I say so!"
Let us know when you can muster an argument beyond "Because I say so!", eh cultist?
On Terra the prime mover for heat retention is our oceans.
Which has jack to do with CO2 being a greenhouse gas. That would be the topic under discussion.
So, are you trying to run from the topic, or are you just being stupid?
Clue for you there's lot's of water on Terra and that's the prime mover of our climate dependent on the solar input. Funny how the global warming experts feel neither of these two factors play a significant role when attempting to convince the public to their cause.
Not funny, how you're just lying outright about the science now. But then, it is what the cult commands of you.
Now take you CO2 and CH4 atmospheric content and shove it up you global warming hole.
Snowflake, you trying to play internet tough guy just makes everyone laugh at you harder.
