Yesterday, our local paper, The Philadelphia Inquirer, reported on a little skirmish at the U.N. climate conference in Copenhagen between the U.S. and China over climate change policy. In essence, the U.S. wants China to open its books in order to determine whether the world's most populous nation is adhering to the voluntary greenhouse gas reductions they are committing to (as a so-called developing nation, China is not confronted with the same requirements as the U.S., European Union countries, Japan, Australia, etc.).
