You're not delusional about that point.
However, I will say this: Even if global warming is a scam (which I don't entirely buy), I would propose that it's a good thing to hit the American people with. We live frivolously and incredibly wastefully. We suck at a black teat, never to be torn away until absolutely forced. I believe the science shows very well that we
are affecting the planet, and if we don't want to see that which we hold dear to go the way of the dodo bird then we must change our habits. If its ultimate purpose is to get us, as a whole, to live in a manner that is less damaging to the environment then I don't think it's necessarily a bad thing.
I should probably try to clarify my point, which is this; I believe that humans have affected the planet about as much as those microbes that changed our atmosphere to a close to 20% O2 content, and that was DISASTROUS for the anaerobic creatures! That being said, I feel that "environmentalism" is entirely selfish. Life will go on, it WILL go on. What won't is human life, and what won't is life as we know it. We love and value that with which we are familiar, that which we find beautiful. To that end, in in that vein, environmentalism is indeed a selfish endeavor. Does that make sense?
Do a little Googling on what happened to world sunlight and temperature levels in the days following the 9/11 attacks because of the massive global reduction in condensation trails from jet airliners. Search using the terms 'evaporation pans' and 'coral light bleaching temperature' (I
think those will net you the research results). In the meantime, Dave and I keep in touch with our paleoclimatologist friend.

Because, let's face it, we still don't know enough about the earth's climate changes pre-modern human to really say with any certainty just how much of the change we're recording is due to human activity versus natural shift.
