Day One: U.N. Climate Summit Begins in Copenhagen

After hacked e-mails, angry Copenhagen sex workers, and months of lead-up time with which to question whether the leaders of the world will actually do anything to slow down global warming, the big meeting is finally here. Today marks day one of the U.N. climate summit held in Denmark's capital, in which diplomats from 192 nations, including more than 100 heads of state, will try to iron out some kind of agreement that would be the successor to the Kyoto protocols. The conference opened with videos about the consequences of climate change; the big decisions won't come for a few days.
