 The people's climate march will take place two days before President Obama and world leaders attend a climate summit at the UN. Climate change will bring more extreme weather and action is now more urgent than ever. Millions of people around the world gather in the largest climate action march in history. The biggest gathering seeking to address climate change ever. 2,000 rallies in 162 countries from Paris, Melbourne, Australia, Rio de Janeiro. Activists are the only the streets to demand action on climate change. We are here because we are redefining this moment. We are also a massive people's march. I hope the leaders of the world listen. We're the first generation to feel the impacts of climate change and the last to do anything about it. Okay, well, please don't give up the criticisms, Keith. Mark, we cannot pretend we do not hear them. We have to answer the call.
