California released its first comprehensive plan for adapting to climate change in 2009, and updated that strategy with the 2014 report Safeguarding California: Reducing Climate Risk. Since 2009, California has experienced several of the most extreme natural events in its recorded history: severe drought, an almost non-existent Sierra Nevada winter snowpack, five of the top 20 largest forest fires ever recorded in the state in terms of acreage burned, and back-to-back years of the hottest average temperatures. This document details how California will build the resilience of our residents, communities, and ecosystems to the emerging impacts of climate change. This section on Public Health is one of 10 implementation plans presented here represent a master blueprint for executing actions recommended in the 2014 report Safeguarding California: Reducing Climate Risk, as called for in Governor Brown’s April 2015 Executive Order (B-30-15).
