Arithmetic saves the day: Solar cells still an option.

Realclimate.org has a great post today called "An Open Letter to Steven Levitt." In case, you haven't heard, this is the economist, and one of the noted authors of the Freakonomics, who recently published Superfreakonomics, a book that is fast gaining notoriety as being fraught with many errors on the issue of Global Warming.

Essentially, the post does a great job in showing how some simple arithmetic could have easily demonstrated problems in one of the claims provided in the new book (on why utilizing Solar Energy would effectively be worse for Global Warming).

It's a wonderful piece, starting off as below, and definitely worth reading all the way through.

Dear Mr. Levitt,

The problem of global warming is so big that solving it will require creative thinking from many disciplines. Economists have much to contribute to this effort, particularly with regard to the question of how various means of putting a price on carbon emissions may alter human behavior. Some of the lines of thinking in your first book, Freakonomics, could well have had a bearing on this issue, if brought to bear on the carbon emissions problem. I have very much enjoyed and benefited from the growing collaborations between Geosciences and the Economics department here at the University of Chicago, and had hoped someday to have the pleasure of making your acquaintance. It is more in disappointment than anger that I am writing to you now.
