i beg your pardon.....it's 4/10 of 1%!!!!<quoted text>
You're very addled. First, co2 is not the only greenhouse gas. Others are actually more impactful. Your percentage is wrong. And even if the percentage were correct the mechanism of greenhouse gases, mostly co2, is perfectly well known by everyone.
it's still a minor trace gas.
so go pound sand, son.
what mechanisms are you claiming to know, sport? are you the shining star who can back up your claims? nobody else here can. maybe you're 'special'.
