What if "made-made global warming" DOESN'T exist? Can we afford to spend several trillions of dollars (thus destroying our economic system, our personal freedoms, and all that we and our ancestors have toiled over ...
OK, let's start with that, the economic impact. Largely, we're talking about reduced use of fossil fuels. Well, yeah - our economic system is based on unsustainable exploitation of fossil fuel, so like it or not, we're going to have to face this some day, and the sooner, the less catastrophic. So on this point, we can't afford not to. I mean, seriously, oil and coal aren't being created at the rate we burn them, correct? I know just the word "sustainable" makes me a commie, but how was I going to fool you anyway.
Will our economy be eviscerated by this change? I don't accept that premise. I don't spend a lot of time reviewing climate change literature so that I can argue about it on this tuba bulletin board, but - at least, less of our oil money goes to all those friendly countries around the globe, right?

As I understand it, the change is already proving beneficial to some animals, unfortunately insects that damage spruce trees. The notion of "undeniably demonstrated" is of course vacuous if there exist large numbers of people who are so dedicated to denial, and I'm not really motivated to dig up the details on as much of the scenario as we know, but the way I've heard it, expect catastrophe. Even if the temperature change itself didn't matter to any organism (though it will), there will be changes in weather patterns that are bound to seriously disrupt agriculture, for example.
