I'm sorry, I'm just another hack douchebag on the internet and not a 'science type', but how does this make Mars a good "control group" when atmosphere is the main problem with Earth?
I admit I don't know squat about solar radiation(nor care to), but I get that it's rising, that's not exactly a shocker, right? I would think that is 'common knowledge', too. I mean, If someone like me has heard that before, then it has to be out there, right?
Well, anywhoo, Isn't the rational point of all this is that man is not helping the situation by polluting the planet?
