Welcome to Cop15, the UN Conference on Global Warming being held in Copenhagen. Denmark is not easy to forget. In the first place, every school child knows the tales of fearless, seafaring Danes. In the second place,every traveler remembers Copenhagen as the city of $20.00 hamburgers and $40.00 seven minute taxi cab fares. Copenhagen is, in fact, the second most expensive city in the world, just slightly less expensive to live in than Oslo. But that will be nothing compared to the price the world pays for this conference.
