More than 400,000 people turned out for the People's Climate March in New York City on Sunday, just days before many of the world's leaders are expected to debate environmental action at the United Nations climate summit.
Early reports from event organizers are hailing the turnout as the largest climate march in history, far bigger than the Forward on Climate rally held in Washington, D.C., last year. High-profile environmentalists including Bill McKibben, Leonardo DiCaprio, Jane Goodall and Vandana Shiva marched alongside policymakers such as Sens. Sheldon Whitehouse (D-R.I.), Bernie Sanders (I-Vt.) and Charles Schumer (D-N.Y.). U.N. Secretary-General Ban Ki-moon and former Vice President Al Gore were also there, and more than 550 buses carried in people from around the country.
The rally came as 120 world leaders, including President Barack Obama, are expected to convene Tuesday at the United Nations in New York to discuss ways to tackle the growing threat of carbon pollution.
