Scientists can't predict the weather two weeks from now, but we are supposed to believe that they can predict it 20 years from now with infallible precision?
Of all the potential causes of global warming - the natural ebb and flow of the climate, sun activity, bovine flatulence , etc. - we know for certain that human pollution is the only cause?
Is it possible that human pollution is only partly responsible for global warming?
Do we even know if it is reversible at this point, assuming we caused it in the first place?
We are supposed to upturn our economies for that? While letting the really big polluters such as China escape any costs for it?
Even if there is global warming . . . so what? It will take thousands of years to reach the 23 feet of ocean rising Al Gore claims will happen, and the oceans have risen mere centimeters in the last century or so. Are humans now suddenly incapable of adapting to climate changes that have occurred many times before throughout our development as a species?
Global warming has indeed occurred innumerable times before, at levels far higher than we are experiencing now. And yet . . . how did the polar bear as a species survive?
Here is the real question: how do we know this isn't some scam by radical environmentalists to destroy capitalism by other means? It isn't as if they haven't used scare tactics and specious theories before . . .
