Our Climate Challenge

In the last decade, Californians have endured historic wildfires, severe drought, rising seas, flood damage, and record high temperatures – all driven by climate change. While the impacts vary across regions of California, the evidence is clear – every corner of the state is already experiencing climate change impacts, requiring sustained commitment to ambitious emissions reductions and proactive implementation of climate adaptation and resilience efforts. Cal OES has been at the forefront of planning for, responding to, and recovering from climate impacts. The Adaptation Planning Guide (APG), State Hazard Mitigation Plan (SHMP), and Hazard Mitigation Grant Program coordination all help make California more resilient to climate hazards. Cal OES continues to further resiliency through effective, on-going collaboration to ensure people and property are protected from all hazards.

California Climate Adaptation Guide

California Adaptation Planning Guide

The APG, is designed to support local government, regional organizations, and climate collaborative groups to integrate best practices and current science into their adaptation planning efforts. Individual communities may choose to follow this framework, or they may organize their adaptation efforts differently. All topics may not be relevant to all communities. Regardless of the preferred organizing structure, this APG recommends an approach that integrates climate adaptation and resilience across sectors. The APG provides helpful resources to local governments as they comply with state requirements for local adaptation planning, and provides recommendations and advice on community-level climate change adaptation planning.
