Obama's Company In Copenhagen

President Obama hadn't announced until Wednesday whether or not he'll be going to the UN climate summit in Copenhagen (he will be), but some other top world leaders had. Here are the other world leaders who will be in attendance: U.K. Prime Minister Gordon Brown, French President Nicholas Sarkozy, German Chancellor Angela Merkel, Brazilian President Luiz Inacio Lula da Silva, Japanese Prime Minister Yukio Hatoyama, Indonesian President Susilo Bambang, and Australian Prime Minister Kevin Rudd.

Chinese President Hu Jintao and Indian Prime Minister Manmohan Singh have yet to announce whether they'll be attending.
