To anyone who criticizes a scientific theory for not being proven... gravity isn't proven. In fact, there isn't a single thing in science that is proven. That's why they're called theories. However, for something to even become a theory it has to tested rather extensively, so it's not so easily dismissed.
That's not entirely true, some basic concepts have been proven beyond any doubt. For instance, the existence of cells, the fact that a ind can be conditioned, mostly psychology and biology. Though that's really fairly irrelevant here. I'd like to say that climate change is among the more tested theories and it's one that's more likely to be true. Again, not being cautious becomes an unwise risk to take.

Right, the important part. See, I'm better at waffling through things without ever getting to the actual point, so I'm going to insult this rather than respond to it.
No.
Weather system: We understand it fairly well, just not as well as other things, so there is a fairly wide margin of error.
It also stands to reason that increased carbon dioxide (refuse to write CO2 to refer to it because the notation makes no scientific sense and you can't get subscript here) will increase temperature, and based on what we do know of meteorology, we can guess (not beyond any doubt, but beyond a reasonable one) what will be affected worse if we persist. It doesn't look pretty.
Then the other gasses that never were there... yeah, that makes it even worse.
Honestly, it's fix it now or wait twenty years to see if the hypothesis is proven. I have to take the unscientific route here, unfortunately.
And as for your moral question:
Economic collapse. Any day. Society has gotten fat and lazy, perhaps a shake-up (even if it shoves me and others below the poor bracket) is what we need. It would at least make things interesting for a couple decades. But that's philosophy again.
My point is essentially, it's an unnecessary and unwise gamble to take. I'd prefer to fix things up before they get worse. And they can get worse.
