March for Climate Leadership Over B'klyn Bridge

Hundreds of New Yorkers joined environmental advocacy group Greenpeace this past Saturday in the March for Climate Leadership across the Brooklyn Bridge. The march was part of the largest global day of climate action ever as one of more than 4,500 events in over 170 countries to call on President Obama and other world leaders to secure a fair, ambitious and binding global deal in Copenhagen this December at the UN Climate Change Conference.
There were more than 50 events throughout New York City, as reported by the New York Times. Why was the number 350 on so many signs carried by demonstrators? According to the report, 350 parts per million is the upper limit for heat-trapping carbon dioxide in the atmosphere.
