Hmm, I was under the impression that cosmologists cared less about Earth specifically and more about the universe generally. I could be wrong though, so I'll retract point #1. :p:

lol you must have hawk eyes to catch that mistake/typo.

They study the atmospheres of other planets which probably helps understand the atmosphere of our own. My logic behind it. Understanding the effects CO2 has on another planet would help us understand the effects it'd have on ours.

Well

Venus is your example

Factors like gravity, solar winds, carbon based life forms, magnetic fields... will complicate the comparison

Makes sense, although I can't say I've ever heard of a cosmologist publishing a paper on climate change.

Or we can just study the effects on Earth much easier... what experiments do you think they are doing on other atmospheres? I don't see how that would be useful considering the infinitely greater abundance of research we've already done on Earth. We have enough information to make pretty good models, and they are only getting better.

Venus can help you understand how crazy it can get once heat gets trapped.

They do call it "Earth's evil twin"...

That's pretty funny actually. Unfortunately, this here is not an April Fools' joke.
