Because, while Schwarzenegger boasted at Georgetown that California is "sending the world a message" on global warming, his behavior and his rhetoric send a different signal: Conserving energy is for girlie men.
I will receive many e-mails defending Schwarzenegger -- all along the lines that at least he believes in global warming. And he has signed bills to force other people to conserve in the future.
After all, no one really expects stars or rich people to sacrifice. All the glitterati have to do is really believe in global warming, maybe ride in a hybrid to the Oscars -- and then their carbon trails (which are much larger than those of people who take the bus every day) won't stink.
It's laughable. Those who believe that global warming is caused by man -- I am agnostic on that score -- claim that they are on the side of Science. That's Science with a capital S.
Yet they applaud when a so-called leader on global warming speaks as if "environmentally muscular" technologies and carbon offsets can manufacture a 25-percent reduction in greenhouse gases by 2020. They have this odd belief that the key to fighting global warming is not by cutting energy use, but by believing in global warming. They embrace wishful thinking -- and call it science.
