25 SEPTEMBER 2014
From around the country and across the globe, an estimated 400,000 marchers came to New York City for the People's Climate March on Sunday.
The march coincided with the start of the United Nations Climate Summit. The meeting, which began Tuesday in New York, brings 120 world leaders together in an effort to improve upon the last summit, which was held five years ago in Copenhagen and called "disappointing in substance and hectic in progress."
