At the next cafe on Climate Change, my friends from LightsOutSF will be in the audience. LOSF is an excellent example how individuals can make a big impact on climate change.
LOSF is a citywide energy conservation event on October 20, 2007. On this night, they are asking the entire city of San Francisco to turn off all non-essential lighting for one hour.

Potential Impacts:
* Sea level rise
* Greater beach erosion
* More frequent El Nino conditions – More rain = less snow in …
