For more than a decade, the State of California has undertaken periodic scientific assessments with the goal of understanding future climate change impacts on the state. For the first three such assessments, released in 2006, 2009, and 2012, a portfolio of research projects investigated climate change impacts, and the assessment report described the results of these studies. The recent Fourth Climate Change Assessment, released in August 2018, includes a new element: regionally focused assessments that survey the scientific literature and summarize the state of knowledge about climate change impacts in the region.
The Center for Climate Science is honored to have led the Los Angeles Region chapter of the regional assessments. Coordinating lead author Alex Hall and lead author Neil Berg convened an expert author panel to report on climate impacts to water, energy, transportation, public health, environmental justice, agriculture, ecosystems, and a host of other sectors. With regional stakeholder input, the authors summarized the state of the science on observed and modeled climate change, what it means for people and natural systems, and what is being done to adapt. The report also identifies knowledge gaps and opportunities for further research to answer critical questions.
