The city introduced a climate action plan back in 2004. In case you haven’t read this *exciting* tome, I’ve done the work for you. All the numbers are circa 2004.
Goal: 20% Green House Gas (GHG) reduction by 2012 (20% below 1990 levels) – 7.2 million tons of CO2
Current GHG production/year: 9.7 million tons of CO2 produced
Potential Impacts:
* Sea level rise
* Greater beach erosion
* More frequent El Nino conditions – More rain = less snow in …

Melissa Capria & Cal Broomhead discuss climate change in San Francisco in this video. It’s long, but a good watch.
Takeaway
First off, the interviewer asks zero tough questions. The piece is light, but gives a good overview.
SF has a massively aggressive GHG reduction target, more than Kyoto, more than the California state plan. About half GHG emissions come from transportation, half from buildings (heaters, cooking, electricity, etc.).
The city sees a few ways they can influence GHG emissions:
1. Conservation/education
2. Technical assistance to businesses (engineering consulting)
3. Incentives (tax breaks, …

However, with increased oceanic temperature, the arctic is showing unprecedented summer shrinkage. Any man who has been in a cold swimming pool knows the feeling.
The study released by the NOAA, National Oceanic and Atmospheric …
