Building Climate Resilience

California is bearing witness to the devastating impacts of climate change. In 2020 alone, wildfires of historic size, scale, and scope swept across our state. Lives were lost; homes and businesses were destroyed; and nature we treasure is gone. These fires took place in the middle of a deadly pandemic and heatwave, and on the heels of a prolonged drought.

The Natural Resources Agency is committed to doubling down on our climate action through policies, programs, and partnerships that also increase equity, improve public health, and create economic opportunity. You can read more about our partnerships, programs, tools and resources below.

We are currently partnering with sister agencies and stakeholders to drive on and implement:

Climate Action

The Natural Resources Agency is statutorily required to release a state strategy to build climate resilience every three years (AB 1482, Gordon, 2015).  We have recently released the draft 2024 California Climate Adaptation Strategy; it can be accessed via our main Adaptation Strategy webpage: More information on the 2024 Update and process can be found here: Learn more about the 2024 State Adaptation Strategy

Review Past State Adaptation Strategy Documents

CAs Climate Change AssessmentsSince 2006, the State has undertaken four comprehensive climate change assessments. These assessments provide a state-of-play on the best available climate change science, and inform the updates to the State’s Adaptation Strategy and the state’s actions to build climate resilience.

  • What communities will be hardest hit by sea level rise?
  • What does increased likelihood of drought mean for food production?
  • What are the implications of decreased snowpack on water supply?
  • When and where will temperatures rise to the level of creating a public health concern?

Assessments help us understand what climate change means for our future, and empower us to plan accordingly. California’s most recent assessment provided regionally specific and actionable climate science, which has supported decisionmakers across the state. California’s climate change assessments were codified in SB 1320, and the Natural Resources Agency is excited to partner with sister agencies to continue California’s legacy of science-based climate action. To learn more about California’s Fifth Climate Change Assessment, which is currently underway, click here

California’s Extreme Heat Action Plan was released April 28, 2022. The plan provides a strategic and comprehensive set of state actions to adapt and build resilience to extreme heat. It outlines California’s all-of-government approach to mitigating the health, economic, cultural, ecological, and social impacts of increasing average temperatures and heatwaves. As called for in SB 306, this plan will be updated in 2026 and every three years thereafter.

Read the Extreme Heat Action Plan (18 MB)

The content and organization of this plan were guided by extensive public input, including listening sessions, regional workshops, as well as consultations with California’s Native American Tribes. 

In October 2022, we hosted California’s first Extreme Heat Symposium to build on the work of the Extreme Heat Action Plan and inform heat adaptation decision-making and actions across sectors and regions.

California is driving on a number of strategic plans to achieve our climate change goals. Many of these strategies are developed and implemented by entities within the Natural Resources Agency. These plans inform policy makers and prioritize funding for grants, projects, and programs. Examples include:


Wildfire Plan coverCalifornia’s Water Supply Strategy (2022):  The strategy centers on actions to stretch existing water supplies and invest in new sources as climate change makes precipitation more erratic. The targeted actions sharpen focus on a set of actions in the Water Resilience Portfolio, California’s water policy blueprint.


Wildfire Plan coverCalifornia's Wildfire and Forest Resilience Action Plan (2021):The Wildfire and Forest Resilience Action Plan is designed to strategically accelerate efforts to: restore the health and resilience of California forests, grasslands and natural places; improve the fire safety of our communities; and sustain the economic vitality of rural forested areas. This Action Plan will serve as a roadmap for implementing the Agreement for Shared Stewardship of California’s Forest and Rangelands with the United States Forest Service, and for aligning the state’s efforts with other federal, local, tribal, regional and private organizations.


Water Resilience PortfolioCalifornia Water Resilience Portfolio (2020): Water is central to nearly everything we value in California. Healthy communities, economies, farms, ecosystems and cultural traditions depend on steady supplies of safe and affordable water. Those values are increasingly at risk as California confronts more extreme droughts and floods, rising temperatures, overdrafted groundwater basins, aging infrastructure and other challenges magnified by climate change. For some of California's most vulnerable populations, the risks are particularly acute. The Water Resilience Portfolio was developed to improve California's capacity to prepare for disruptions, withstand and recover from climate-related shocks, and adapt into the future.


Strategic Plan to Protect CAs Coast and Ocean 20202025Ocean Protection Council's Strategic Plan to Protect California's Coast and Ocean 2020-2025 (2020): OPC's Strategic Plan to Protect California's Coast and Ocean 2020-2025 recognizes the threats that climate change poses to the State's coastal and ocean ecosystems and provides a roadmap for protecting and adapting these resources in the face of sea-level rise, ocean acidification and hypoxia, ocean warming, and other climate-driven stressors. The Strategic Plan also prioritizes understanding the role of California’s network of marine protected areas in providing ecosystem resilience to climate change and ensuring fisheries and fishing communities can adapt and thrive in changing ocean conditions.


Integrated Energy Policy ReportIntegrated Energy Policy Report (2019): California is working to make sweeping changes in its energy system to address climate change, improve air quality, and make sure that all Californians share in the benefits of the state's clean energy future. The IEPR assesses a variety of energy trends and issues to inform our decision-making as we work to create an energy system that is clean, modern, and safe, while increasing its resiliency to climate change and improving the equity of how clean energy benefits are realized.


CA Forest Carbon PlanCalifornia Forest Carbon Plan (2018): Our state is blessed with 33 million acres of forestland and an urban forest canopy that together capture and clean our water supply, provide habitat for countless wildlife, cool our cities, support local economies, and serve as spiritual and cultural centers for indigenous and local communities across the state. Forested lands also are the largest land-based carbon sink. This plan lays out recommended actions to achieve healthy and resilient forests based on what we know today about our forests and how climate change will evolve in California.


State of CA Sea-Level Rise GuidanceCalifornia Sea-Level Rise Guidance (2018): OPC, in coordination with coastal and ocean state agencies and the Governor's Office of Planning Research, leads the development of the State's Sea-Level Rise Guidance Policy and subsequent updates every five years. The Guidance is used by California's coastal zone management agencies to support planning and permitting activities. The 2018 update incorporated advances in ice loss science and projections of sea-level rise and includes guidance to address the needs of both state agencies and local governments.


CA State Wildlife Action PlanState Wildlife Action Plan (2015):The State Wildlife Action Plan examines the health of wildlife and prescribes actions to conserve wildlife and vital habitat before they become more rare and more costly to protect. The plan also promotes wildlife conservation while furthering responsible development and addressing the needs of a growing human population. In the latest update of the State Wildlife Action Plan, the California Department of Fish and Wildlife incorporated climate change impacts and adaptation, including dozens of strategies and targets for California's ecoregions.


Adapting to Rising Tides ART ProgramAdapting to Rising Tides (ART) Program (continuous): the San Francisco Bay Conservation and Development Commission works with stakeholders around the Bay Area to understand their vulnerability to sea level rise and how future flooding will communities, businesses, infrastructure, and natural systems. Since 2011, the ART Program has conducted research and provided tools, guidance, and information to local cities and counties to help support complex decision-making around climate adaptation. ART has conducted projects at the regional, local, and sectoral scales.


Delta AdaptsDelta Adapts - Creating a Climate Resilient Future (forthcoming): California relies on the Sacramento-San Joaquin Delta in many ways. It supplies a portion of the drinking water for 27 million Californians, fuels California's $3 trillion economy, and is a biodiversity hotspot for more than 750 plant and animal species. Changes in climate put the state's water supply, economy, and biodiversity at risk—decreasing water quality and increasing stress on levees that protect residents, farmland, and the state's network of public utilities from mass flooding, and the species who thrive in the region's ecosystems. The Delta Stewardship Council working with partners to undertake a regional vulnerability assessment, and develop a regional climate adaptation plan.

The Resources Agency contributes to California's climate action through programs that reduce greenhouse gas emissions, sequester carbon, and build resilience to the impacts of climate change. Examples include:
