On Monday, about 175 people gathered in Emeryville, Calif., to board a train to the People's Climate March in New York City this weekend.
Activists are calling it "the People's Climate Train." It will roll across the country this week, picking up more climate activists along the way, before stopping in N.Y.C. for the march that will have an estimated 100,000 climate activists in attendence on Sept. 21.
Environment California and the other Environment America affiliates have been working 'round the clock to help make the People Climate March the biggest action on climate to date.
The march is set to happen as world leaders descend on New York for the United Nations Climate Summit that UN Secretary General Ban Ki-moon convened to urge all countries to take action on global warming.
