Muller: "The fact is if you dump carbon dioxide into the atmosphere half of it disappears in the first year, and the rest will probably get mixed out over the next 20 to 25 years"; "The U.S. is responsible for .15 degrees Celsius...US automobiles have contributed almost nothing to global warming and they will contribute almost nothing in the future"

[Muller, June 21, 2012]: There are statements from scientists who should know better saying it [carbon dioxide] stays up there for hundreds of years. The fact is if you dump carbon dioxide into the atmosphere half of it disappears in the first year, and the rest will probably get mixed out over the next 20 to 25 years.

Greg Dalton: So you’re saying we could reduce it quickly and sharply

Richard Muller: We could reduce it. But we can’t, not you and me, it has to be China.

What really bothers me is that there’s so many meaningless things out there. People say let’s get all electric automobiles. The U.S. is responsible for .15 degrees Celsius. Of that, U.S. automobiles are responsible for one quarter of that which is .05 degree, .04.

US automobiles have contributed almost nothing to global warming and they will contribute almost nothing in the future. And if we think the thing to do is for us to make electric automobiles. Well, electric automobiles in China produce more carbon dioxide than gasoline automobiles in China, because they’re based on coal.
