Thousands fill NYC streets for climate march

NEW YORK – Demonstrators are making their way through Manhattan's streets as part of a series of global marches over climate change.

Thousands filled the streets Sunday near Columbus Circle and Broadway, including actors Mark Ruffalo and Evangeline Lilly.

Other cities held similar marches. In London, organizers said 40,000 took part including actress Emma Thompson and musician Peter Gabriel. A march in Melbourne, Australia drew 10,000 people.

The Manhattan march comes two days before the United Nations Climate Summit. More than 120 world leaders will convene Tuesday for the meeting aimed at galvanizing political will for a new global climate treaty by the end of 2015.

The march also coincides with New York's annual climate week, which will include a string of events this week, some featuring celebrities, CEOs and climatologists.
