AMerica is unique in its utter prowess at pretending things aren't real when the truth poses an inconvenience. We rely on mass consumerism and environmental degradation to fuel our economy... God's economy, as they'd have you believe. Some degree of alarm is necessary in order to try to curb destructive behaviors. If you put a Republican on a sinking ship, he'd deny it was sinking and insist everyone go about their business even as the water's puring in, just so he wouldn't miss dinner! The Europeans don't quite have so much to lose, because they're not the ones who are wealthy from massive industry. The US is, so we have a slice of the population who'll really fight tooth and nail to shoot the whole green movement down.
Light a smoke, take a spin in the ol' SUV, and relax, guy! That's America's stance. The kids are the ones who'll see the effects in their lifetime, as are the young adults. Once again, Europe has shown that they've pulled ahead in terms of civility in the modern world.
