Climate change has been getting a lot of notice lately. From the highly acclaimed Years of Living Dangerously series on Showtime to the EPA’s recent moves to restrict carbon emissions from power plants, we’re making progress. But it’s not enough. We need to get serious about cutting greenhouse gas emissions and moving aggressively to a clean and sustainable energy future.

This year, in conjunction with the annual meeting of the United Nations, Secretary General Ban Ki-moon is organizing a “climate summit” to prepare world leaders ahead of the next round of climate negotiations scheduled for 2015 in Paris. Climate change activist organizations from around the country and across the globe see this as an opportunity to weigh in and tell our leaders it’s finally time to take concrete actions to curb the effects of global warming. The People’s Climate March is the result.

You can do three things:

1. Mark Sept. 21 on your calendar and join thousands from around the world in marching for definitive action on climate change.
2. If you’re a member of an organization or group, join the growing list oforganizations supporting the March, including Greater NYC for Change.
3. Get out the word. Come join 350NYC this Saturday, Aug. 9, to spread the word to other New Yorkers to join the March next month.
