Indicators of Climate Change in California

Indicators of Climate Change in California characterizes the multiple facets of climate
change in California. The report tracks trends in greenhouse gas levels that influence
climate, changes in the state’s climate, and the impacts of climate change on
California’s environment and people. The report does this by bringing together and displaying large amounts of scientific data as “indicators”. These indicators rely on monitoring and research activities carried out by state and federal agencies, universities, and other research institutions. The
indicators selected reflect current understanding about the role of heat-trapping
greenhouse gases in climate change, how temperature and precipitation are changing,
and how these changes are affecting the environment, specifically freshwater and
marine systems, as well as humans, plants and animals. This 2013 edition updates a
report published in 2009.
