TX Kevin, shut up. The reason is that these morons are going to waste YEARS and spend MILLIONS for no other reason than to try and discredit what is already Scientific Theory(fact) and needs to be addressed immediately. Waiting even 4 years could push us past the point of no return in which we are unable to slow or even stop the polar caps melting, sea level rise, and the destruction and death associated with both. Think about what happens to the world if every major port city, most of which are pretty close to zero elevation are flooded with even 6 inches of water that never recedes. All the chemicals that leech from buildings and the ground will destroy entire vast swaths of ocean life and our ability to eat them. The extreme changes in weather patterns and currents will disrupt shipping and the delivery of goods worldwide, etc etc, so on and so forth FOREVER screwed.
