Instapundit says it nicely:
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.
I'll add to that in saying I won't take it seriously until they are calling for all coal-fired plants to be converted to nuclear.
