This topic is quite long to read, so I'm just going to throw my ideas out there.
Firstly, as has been said on the first page here, global warming is Far more the cause of nature than it is of human influence. (Astronomically, if my Earth Science Prof is right.)
Secondly, as was also stated, we have no way of knowing what the results of global warming will be, especially since warmer water means more precipitation, which means more cloud cover, which means more cooling.
Finally, I don't see why we should cut our emissions just to satisfy standards that we have little effect over. If we're going to cut emissions, let's do it because of the harms of pollution. Furthermore, rather than simply cut emissions, let's advance toward technologies for the new century, and get rid of ridiculous things like using gasoline for cars, because we have other ways to run vehicles, several of which could probably be mass-produced if we properly invested in them.
