It is not all gloom and doom. The Copenhagen Summit was the first of its kind. Never before had the international community been so well represented in its willingness to engage in efforts to save the world from the effects of climate change. It was in the context of Copenhagen that the United States committed itself to a thorough - if insufficient - emissions reduction scheme. The other top polluter, China, also began to use a different language compared to only a couple of years ago. Progress has been made. But given the scale of the challenge, it is profoundly unsatisfactory.
