The Bay Area will be subject to multiple, new or worsening hazards over the next several decades due to global climate change from increased greenhouse gas concentrations in the atmosphere. The approach to managing climate change risk is twofold – climate change mitigation, which seeks to stabilize or reduce greenhouse gas emissions and limit the effects of climate change, and climate change adaptation, which seeks to lessen the impact of changes already underway. Many Bay Area cities, counties and special districts have already begun to understand their risks and take action, and this movement will continue to grow and become more integrated with planning for other hazards as well as long-term land use planning. The following represent resources for local governments to assist in understanding their risk and planning for climate change.
Climate Change Mitigation
Climate change mitigation encompasses actions being taken to reduce the rate and scope of long-term climate change through reducing greenhouse gas (GHG) emissions. Around the Bay Area, many cities have taken actions to limit their GHG emissions through energy efficiency, improved public transportation, encouraging walking and biking, and diverting waste from landfills through GHG inventories and Climate Action Plans.

Climate Change Adaptation
Climate change adaptation is a response to global climate changes that have already begun to impact ecosystems and seeks to reduce vulnerability to the effects of climate change. Even if GHG emissions stabilize soon, the effects of increased GHG will likely last many years and society will need to adapt to changes in temperature, precipitation, sea level, and other effects. Many Bay Area cities have begun to examine adaptation actions and create Climate Adaptation Plans.
