Not sure attacking "conservative white males" does anything constructive to advance the discussion, but whatever. We all come to this board with our own biases and self-motivations.
Kinda difficult at this point, at least in the opinion of this particular "conservative white male," to argue that man's actions haven't had some negative effect on the global climate. And frankly it infuriates me when so many of the people who sit next to me in church every Sunday, and as such should have a vested interest in protecting the planet they believe was created by God, don't even consider the possibility of man-made global warming simply because it's a "liberal" concept.
At the same time, this planet has been around a long, long time. The earth has seen prolonged periods of warming and cooling (hello Ice Age!) long before there were factories and automobiles with internal-combustion engines. I've read many respected scientists who believe the alternating pattern of warming and cooling will continue regardless of man's impact on the process.
Conservative or liberal, black or white, I'd hope we could at least agree that it is our responsibility as the people who inhabit this wondrous planet to nurture it and make sure we have something to pass on to future generations. While thoughtful people can disagree on how to go about that, at least it would be a starting point.
But considering the sorry state of our political discourse, it seems that this is just another area in which we are destined to fail.
