George Bush today reiterated his concerns about greenhouse gases:

And therefore, I remind those who share my concern about greenhouse gases that nuclear energy produces no greenhouse gases. If you are interested in cleaning up the air, then you ought to be an advocate for nuclear power. (Applause.) Without nuclear power here in the United States, there would be nearly 700 million additional tons of carbon dioxide in the atmosphere every year. There is no single solution to climate change, but there can be no solution without nuclear power.
