We are an all-volunteer San Diego County organization concerned about climate change. We work to increase awareness of climate change and advocate for reducing greenhouse gas emissions. In September 2011 we brought together hundreds of San Diego County residents, and we collectively called on our elected representatives to take immediate, strong action on climate change as part of’s international day of action on climate change.

Our organization’s values include: action-oriented; teamwork; collaboration; shared-leadership; respect for people; and peaceful demonstrations.
We’re San Diegans from different communities, of different ages, working or studying in different fields – some of us are retired – who have come together to say, “Enough is enough. Global climate change is real. We must have a clean energy future. We must do this now.”
