Glen Reynolds wants to see some shared sacrifice:

THE BIG GLOBAL WARMING PUSH IS UNDERWAY: I won’t take it seriously until they ban private jets and stretch limos.
No, seriously. A Gulfstream III releases 10,000 pounds of carbon dioxide an hour. How can we demand “sacrifice” from ordinary Americans when our leaders — including those who call for the sacrifice — are flying in jets like this? If commercial first-class isn’t good enough, they should stay home.
