  • Fourth California Climate Change Assessment
    Building on California's prior investments in regionally relevant climate science, a Fourth California Climate Change Assessment was held in August 2013.

Please see the Fourth Assessment Scope of Work for further information.
  • Safeguarding California Plan
    The California Natural Resources Agency, in coordination with other state agencies, has updated the 2009 California Climate Adaptation Strategy. The Safeguarding California Plan augments previously identified strategies in light of advances in climate science and risk management options.
  • AB32 Scoping Plan
    The Air Resources Board approved the First Update to the AB 32 Scoping Plan on May 22, 2014. It identifies opportunities to leverage existing and new funds to further drive GHG emission reductions through strategic planning and targeted low carbon investments.
  • Climate Research Plan
    California's climate change policies have been built on the best available scientific understanding, including research commissioned by state agencies to illuminate California-specific knowledge needs. Successfully negotiating climate change challenges requires integrating sound science into local planning, resource management, infrastructure, and public health planning, as well as introducing new strategies to reduce greenhouse gas emissions. This draft Climate Research Plan presents priorities for the next 3 - 5 years for policy-relevant, California-specific research.



The National Research Council has developed a series of videos that explain how scientists have arrived at the state of knowledge about current climate change and its causes.
