If this ice melts in Greenland it can shut down the Gulf Current.

Back in the mid-1970s, we adopted some fairly ambitious goals to improve efficiency of our cars. What did we get? We got a tremendous boost in efficiency.

With millions of family wage manufacturing jobs lost since 2001, we need an energy bill that takes bold action to tap into American ingenuity in order to lead the world in new clean energy technology, rather than playing catch-up to the Japanese, Danish, and Germans.

We can't tell China what to do if we don't do it ourselves. You don't inspire someone to take an action by refusing to take it yourself. We are in a race to be the dominant clean-energy provider to the world. Maybe this goes without saying: We've got to get China into an international protocol and the magic words are "common responsibility with differentiated action."

There is no excuse for this administration shielding information about Iraq and the fact that we have great difficulties there from the American people.

Air is one we hold in common; it has a limited carrying capacity for pollutants and that's being used up by those who pollute the atmosphere. So we have to stop that externality. We would never allow a utility to put their coal slag in a dump truck and back it up to the city park and dump it in unlimited amounts for free. But that is exactly what we do with carbon dioxide and methane.

We've introduced the New Apollo Energy Act, which is, I think, safe to say the most comprehensive and aggressive bill that has been introduced in Congress because it does have the scale, scope, and ambition of the original Apollo Project, and it attacks the problem in every way you can imagine. There's no silver bullet here, but there are lots of opportunities.
