Local governments are responsible for dealing with the impacts of climate change, from providing the first responders to extreme weather events to dealing with the day-to-day implications for public health, infrastructure and economy. The impacts of climate change in California and elsewhere will depend on how quickly humans reduce their emissions of greenhouse gases.
The California Energy Commission (CEC) produced a 2006 report entitled "Our Changing Climate: Assessing the Risks to California," which addresses the statewide implications of global warming. The CEC predicts that California temperatures will increase from 3 - 10.5 degrees Farenheit by the end of the century. The 10.5-degree scenario would be accompanied by sea level rise of as much as 3 feet by the end of the century and steadily increasing after that.
A 1990 study by the Pacific Institute estimated that sea level rise of 3.3 feet (1 meter) in San Francisco Bay would threaten structures valued over $48 billion. To help people visualize the impacts of sea level rise, visit the interactive on-line map (aerial photo view) that shows approximate impact on Bay Area coastlines of various sea level rise scenarios ranging from 0-7 meters or view online video [Quicktime MOV file, 1 MB] showing flooding that could occur in the San Francisco Bay Delta with just 1 meter of sea level rise.
