Kathy and I have had a spirited discussion on global warming. See "Becker on Global Warming" if you want to take a look. Anyway, the Wall Street Journal had an interesting editorial on the subject of U.S. vs Europe and greenhouse emmissions.
The bottom line, despite greater economic and population growth, emmissions growth has increased more slowly in the U.S. in recent years. And the following pretty much sums it up:
"If global-warming activists were as interested in lowering air temperatures as they are in expanding the role of the state, they'd understand that the key to reducing carbon emmissions lies in unleashing the private sector, not capping it. That's the real lesson from the policies- and the results- in Europe and the U.S.
