There is tons of proof for AGW to be real. You of course have only looked at one side; so you wouldn't know. It's half and half, it could be us, it couldn't be us. But do you really want to risk it?
BTW it isn't a ridiculous, how many car accidents have you yourself been in? I haven't been in any, but I still buy insurance. Also, there is a first time for everything. Usually when it's a bad mistake there is only one or two of those mistakes occur. That's why we study history.
Do you want several generations ahead of us learning about the collapse that came from global warming and the years of disasters that followed it? I don't.
Every single argument I have ever seen that attempts to "prove" global warming has been just as easily created as it has been disproved (and by disproved, I don't necessarily mean wrong, but at the minimum, it doesn't end up proving anything). If you have one you'd like to share, be my guest.
Also, if global warming is so positively true, why are there 31,000 American scientists saying it is not?

And saying it's half and half is just your guess. I say it's 99% to 1%, but does that make it true? No. Really, it doesn't matter what percentage may or may not be true, that's not the point. The point is, no one has proven global warming has anything to do with what we as humans are doing, so we shouldn't stop what we are doing.
I hate being inconvenienced and have money taken away from me for some initiative that I do not agree with. It's basically a loss of my freedoms because some idiots convinced people that global warming is real. I will say it could be, but I'm willing to take the risk. If others are not, well, that's up to them. They can walk every day to work if they want (which, by the way, actually creates a larger carbon footprint than driving, but that's another story). Anything to do with "stopping" global warming should be funded by charities, and people that actually buy into the bogus theory should give to the charities. And things like incandescent lightbulbs should NOT be outlawed. If I want to buy an incandescent lightbulb, and someone wants to sell me one, then I should be able to do that.
Oh, and the car accidents example still is ridiculous. We know that car accidents happen. We do NOT KNOW that global warming happens - some people only guess that it does.
