As we enter the second week of negotiations of the United Nations Conference on Climate Change at Copenhagen, which looks no more likely to produce a binding agreement than the first week, it's funny to remember how different things were just a year ago.

A year ago, there was still so much hope for Copenhagen. Heck, people called it "Hopenhagen."

Representatives from nearly 200 nations would be getting together to sign the successor of the Kyoto Protocol, which expires in 2012. It would be a better treaty, with real teeth. Developed countries, which had been emitting greenhouse gases into the atmosphere with abandon in their race for industrial dominance would agree to mandatory reductions in emissions levels. They would also give financial aid to help developing nations develop cleanly.

This was not as naive as it now sounds.
