As for me, while I am a global warming agnostic, I am not stopping anyone from taking the bus. Schwarzenegger and others have argued that new technologies can light the way. But those that exist cost too much, which means that only effective way to cut greenhouse gas emissions is to pass huge energy tax increases.
Newsweek columnist and economist Robert J. Samuelson, a reasoned voice on global warming, wrote that he supports gradually raising the gasoline tax of $1 to $2 per gallon. I wonder how many Californians would be willing to not only pay $4 or $5 for a gallon of gas but more for every commodity. And Samuelson is clear that his modest gas tax can't do much to reduce greenhouse gases.
America's sacrifices could be for naught, as long as China -- which is or is about to be the world's greatest generator of greenhouse gases -- is exempt from any global warming pact.
To go the distance supported by global warming alarmists requires big changes.
If the alarmists are right, the whole world will have to change and it will be onerous. If the global warming alarmists are wrong, much of the sacrifices they demand will have been for nothing.
