Gadhafi takes the stage

World leaders, many reeling from a year marked by global economic freefall and a growing threat from global warming and nuclear proliferation, exhorted one another Wednesday to work together to meet those challenges.

But it was Libyan leader Moammar Gadhafi, both with his entrance and his 96-minute address, who stole the show completely.

Gadhafi called for world unity in confronting crises -- such as climate change and food shortages -- but he expressed ire at the world body and the United States.
