The Guardian newspaper article Who What Where When Why More than 300,000 marchers flooded the streets of New York on Sunday in the largest climate change march in history, vaulting the environmental threat to the top of the global agenda. On a day of 2,700 simultaneous climate events from Melbourne to Manhattan, the US secretary of state, John Kerry, reinforced the calls from the streets for action by calling on world leaders to take the threat of climate change as seriously as Isis or Ebola. Organisers had called the day of protests in order to put pressure on world leaders gathering in New York for a UN summit on climate change on Tuesday. It will be the leaders’ first such meeting in five years. Kerry, in remarks to foreign ministers of the 20 biggest economies, said climate change should be at the top of the agenda despite competition from more immediate challenges. “While we are confronting [Isis], and we are confronting terrorism and we are confronting Ebola, this also has an immediacy that people have come to understand,” he said. “There is a long list of important issues before all of us, but the grave threat that climate change poses warrants a prominent position on that list.” Organisers claimed 570,000 people protested in 161 countries, from a handful of protesters in Aleppo, Syria, to the mega-march by 310,000 through New York City – three times as many as the 100,000 people organisers had expected, and easily overtaking the 80,000 who demonstrated for climate action in Copenhagen in 2009. In Manhattan, the noisy, hopeful cavalcade of protesters – led by Hurricane Sandy survivors carrying placards of sunflowers and Native Americans in traditional headdresses – took over the streets of Midtown, juggling, singing, blowing synagogue shofars and conch shells, whistling and beating drums, with biodiesel-powered floats chugging along. They hoisted a papier-mache representation of Mother Earth and a giant parachute emblazoned with monarch butterflies, and carried signs reading “Melt chocolate, not polar ice caps” and “May the forest be with you”. Leonardo di Caprio marched with Mark Ruffalo; the UN secretary general, Ban Ki-moon, marched with the former US vice-president Al Gore. At least three Democratic members of the Senate also joined. “People are now much more aware in all our countries of how important this topic is,” said the French foreign minister, Laurent Fabius, who joined the march in Manhattan.
Upper West Side mothers pushed expensive strollers alongside protesters carrying signs reading “angry pacifists”. “I think it will make a difference,” said Tashina Red Hawk, aged 10, who wore intricately beaded traditional Sioux Indian dress, and who lives on the Rosebud reservation in South Dakota. “But it would still be good to do all kinds of other stuff.” She went on: “If you don’t take care of the land, it won’t take care of you.”
