9/22/2014 Climate Change Activists Take Over Manhattan to Demand Action - An estimated 400,000 people took to the streets of Manhattan over the weekend to demand world leaders take action on climate change.

Joining the march were several labor unions, former Vice President Al Gore, UN Secretary General Ban Ki-moon, New York City Mayor Bill de Blasio, and celebrities Leonardo DiCaprio and Edward Norton. . . .
