The changing climate has potentially severe economic, health, social and environmental consequences [in Berkeley], including: Threats to coastal infrastructure due to a rising San Francisco Bay: The Bay rose seven inches over the past 150 years. Estimates are that by 2100, the bay could rise up to a meter. Increased incidence of large wildfires: The risk of large wildfires in California could increase by as much as 55% by centurys end. Serious public health threats: Increasing temperatures exacerbate local air pollution, lead to intensified heat waves, and expand the range for infectious diseases. Water shortages: Due to rising temperatures, the Sierra Nevada mountain snow-pack that supplies much of the states water supply could decrease by 80% by centurys end. Loss of snow-pack threatens drinking and agricultural water supplies as well as hydropower generation and the health of the states creeks and rivers. In November 2006, Berkeley voters issued a call to action on the climate challenge by overwhelmingly endorsing ballot Measure G. The mandate was simple but bold: Reduce our entire communitys greenhouse gas (GHG) emissions by 80% by the year 2050. This plan is the result of the campaign that Measure G set in motion. It is rooted in the vision for a sustainable Berkeley that emerged from the climate action planning process. The plans purpose is to serve as a guide for setting the community on a path to achieve that vision. **Updated with 2014 progress report**
