In my experience, it's always good to be optimistic in negotiations. We have a powerful interest in achieving an ambitious and comprehensive outcome in Copenhagen. We have a strong interest in achieving effective global action that addresses this problem. I am optimistic, based on the tone in the negotiations, that we can address some of the major questions. Whether the dynamics of what is ultimately a completely multilateral process will enable us to get there, I can't say. I am optimistic, however, that we can achieve a significant agreement in Copenhagen.
