Nicholas Kristof does the Katrina-to-climate link in a reasonable way in Sunday’s New York Times. He gives props to Portland for taking technologically available and cost-saving steps to reduce their emissions to just above 1990 levels. It really shouldn’t surprise us that it is the state and local levels that are the environmental innovators. It is just usually one state to the south in California where local conditions (read thermal inversions in LA) eventually beget US environmental regulations.
Kristof also provides extensive links at the bottom of the piece, something more pontificators should do.
