SAN FRANCISCO (CBS SF) — A climate action march Saturday in San Francisco drew about 30,000 people and sent a message to Gov. Jerry Brown in advance of the upcoming Global Climate Action Summit, organizers said.

The marchers left the Embarcadero Plaza at 11 a.m., marching to the Civic Center, demanding an end to the global climate crisis, according to Antonio Diaz, organizational director of People Organizing to Demand Environmental and Economic Rights.

Marchers banged drums, played instruments, chanted and sang. When they reached the Civic Center area, the coalition of about 50 organizations did street painting, Diaz said Saturday afternoon.

The paintings depict trees, suns and other symbols of climate justice, he said. The participants in the march belong to a variety of environmental, labor and faith organizations.
