More than 300,000 protesters turned out last Sunday to turn up the heat on world leaders to recognize climate change. the 2-mile People's Climate march began at 86th Street and continued down Sixth Avenue for 6 hours. New York was one of 2,646 climate-change events in 156 countries. They pushed a variety of cause from anti-fracking to opposition to the Keystone pipeline. How poignant that I watched the march from the corner of the block which is home to the International Center for Photography boasting an exhibit of Sebastiao Salgado's latest masterpiece, Genesis - Earth Eternal.
