Scientists from research institutions, non-profits, and the private sector made themselves seen and heard on Sunday, September 21, when 310,000 people marched through New York City to demand action on climate change.  This “People's Climate March” was timed to coincide with a special climate summit for world leaders at the United Nations on Tuesday, September 23. 

Next week is Climate Week in New York City. The happenings begin on Sunday with what promises to be a massive march demanding action to curb human-propelled global warming. On Tuesday, the United Nations will hold an all-day climate-focused summit for world leaders.
