First, Al Gore has nothing to do with Global warming theory other than the fact that he is smart enough to understand it and communicate it. The evidence has been compiled for more than a hundred years by PhD scientists who study it every day. Its hard science, not Al Gore's or anyone else, imagination.
Second, natural warming and cooling cycles are not part of the man made global warming problem. It is proven; it is a fact, and no expert in the field denys it.
Third, you can't simply "prepare" for some of the predicted outcomes of continued warming. dead crops, dead forests, dead ocean, sea level covering major cities, etc. All this stuff doesn't happen tomorrow, but refusing to acknowledge that we have a responsibility to our planet and to our children is the ultimate irresponsibility.
I have no problem with contingency planning for environmental changes we will unfortunately be unable to avoid, but that has to be combined with an understanding of how we as humans impact this earth and doing what we can to keep it in balance. Nobody is talking about stopping oil drilling, but it only makes sense to talk about alternatives for a long term plan. Logical people have been talking about that for decades, long before Global warming was in the news.
Decreasing supplies of oil (yes it is limited), increased effect of emmisions, growing populations and demand for energy, Political instability that will be caused by demand for energy, food, water and space, etc.
A plan to "keep doing what we are doing" is not a plan, and we don't need the short sighted and the ignorant in this country making policy decisions so vitally important.
Republicans need to join the rest of the civilized world and quit acting like a bunch of ignorant bible thumping dopes. Let's talk about how to manage environmental concerns without killing economic growth. Let's drop the head in the sand science denial.
