A participant in the People's Climate March holds her sign as she prepares to make her way through the streets of New York City. The march, two days before the United Nations Climate Summit, is billed as the largest climate march in history.

The People's Climate March is a global weekend of action on climate change. More than 2000 events are planned over 6 continents, including huge rallies in New York and London. The march is held prior to the New York Climate Summit on Tuesday 23 September 2014. The summit, called by UN Secretary General Ban Ki-moon, will be attended by more than 120 world leaders and will be the largest gathering of world leaders to discuss climate change since the Copenhagen Summit in 2009.
