The People’s Climate March in New York City is the centerpiece of the Big Apple's Climate Week . But in addition to the march there are several important activist events preceding it, and many events extending past Tuesday’s United Nations Climate Summit.

Some of the other events are officially sanctioned by the Climate March organizers, while others are run by other activist organizations. Many of the vigils, lectures, prayer services, and panels seem very worthwhile, and they’re listed on the Climate March’s events page and the Huffington Post has a generous listing of religious events on its site. NYC Climate Convergence will hold a series of workshops and teach-ins leading up to the march.

But we thought we’d keep it simple and list the most visible activist events in the next few days in more detail.

The New York City Permaculture Exchange Festival will take place on Saturday, Sept. 20. It’s a satellite event for the Climate March that focuses on sustainable living that will be held in Park Slope, Brooklyn. The goal of the festival is to strengthen the NYC permaculture community, and address issues such as environmental stewardship, urban homesteading, community interdependence, and environmental stewardship.

Many festival attendees will be hard at work making artwork and banners for the Climate March. You’re welcome to join other attendees in making signs while learning more about permaculture. The event will begin at noon and run to 7pm at the Old Stone House of Brooklyn, 336 3rd St., Brooklyn, NY.

Sunday’s rallies leading up to the People Climate’s March. Several pre-march rallies are scheduled to take place on Sunday morning. We’ve listed some of the most notable below, but for a full list, refer to the Climate March’s events page. Three notable events are:

Labor Rally for Climate Justice. Thousands of union members and labor leaders will join a rally on Broadway south of Columbus Circle at 10:45am.

Interfaith Religious Service and Rally. Faith leaders and groups will meet on 58th Street, between 8th and 9th avenues at 11am.

Scientist Rally. Scientists will be meeting up at the Hayden Planetarium at the Museum of Natural History on 81st St. and Central Park West at 11am.

The People’s Climate March will take place on Sunday, Sept. 20 in Manhattan. Organizers expect more than 100,000 people for what is hoped to be the biggest demonstration event ever for climate action. There will be People’s Climate Marches in other cities across the globe, in addition to New York.

Some 1,000 organizations are either participating in the march or have endorsed it. It’s being organized by a coalition of environmental, civil rights and labor organizations including 350.org, Avaaz, the Sierra Club, Climate Justice, and Service Employees International Union.

The march begins Sunday at 11:30am. along Central Park West between 65th and 86th streets. At 1pm, the Climate Alarm will sound, followed by a moment of silence. Then the march will ring out with trumpets, bells, drums, and whistles. More than 30 marching bands will be joining the march at this time.

The march will proceed down Central Park West and go east on 59th Street and continue to wind through midtown Manhattan ending between 2:30- 5:30pm at 11th Avenue between 34th and 38th streets, near the Jacob K. Javitz Convention Center. Transportation from the march’s end can be found to the west at either Pennsylvania Station or the Port Authority Bus Terminal.

Flood Wall Street. On Monday, Sept. 22, a rally reminiscent of Occupy Wall Street will be staged in the city’s financial district.

Event organizers say hundreds of people from across the country have pledged to join the direct action rally, and they expect the number to grow. Flood Wall Street targets capitalism and the current global economic landscape as the chief causes of climate change.

The event begins with a 9am muster at Battery Park, where there will be music and speakers including Naomi Klein, Rebecca Solnit and Chris Hedges as well as frontline community leaders of the Climate Justice Alliance. The march to Wall Street commences at 11am and will end with a mass sit-in in the financial district at noon.
