Answer:
1) We don't really believe Global Warming will occur; it's probably just a liberal myth created to socialize (read: impoverish) the world
2) If Global Warming occurs, humans are hugely adaptable, and we'll cope just fine
3) If Global Warming occurs, we doubt Al's doomsday scenarios
4) Preemptive action to prevent Global Warming requires mass starvation (how will you move food?); we're not excited about global genocide
5) Kyoto alone will have virtually no effect on Global Warming, if it is true
6) No other country has taken proactive action that resulted in adherence to Kyoto. Only Russia and the U.K. have achieved their goals via de-population (Russia) and Thatcherite breaking of the coal unions in favor of natural gas.
7) If Global Warming is occurring, it's a result of natural forces far beyond human control.
The most important answer is that global warming or cooling has been occurring for the entire natural history of the planet, that it (climate change) is entirely natural and expected, that there is NO EVIDENCE that human activity either accelerates or retards climate change, or that such a thing is even possible.
