Climate change refers to the change in measures of climate lasting for an extended period of time, such as changes in temperature, and precipitation. Climate is influenced by its own internal dynamics, and by changes in external factors, both natural and human–induced. Solar radiation and volcanic eruptions are natural factors, while changes in the composition of the atmosphere resulting from greenhouse gases or aerosols are human-induced factors.
The Office of Environmental Health Hazard Assessment researches and presents indicators in periodic reports describing how California’s climate is changing and how these changes are affecting the state. Indicators are scientifically-based measurements that track trends in various aspects of climate change.
OEHHA focuses on human health studies relating increased temperatures to adverse health outcomes such as death and illness including hospital visits, emergency room visits, and birth defects. OEHHA has contributed to the growing body of literature linking deleterious health effects to increasing temperatures and heat waves. These studies have helped identify groups who are vulnerable to heat-related mortality and illness.
OEHHA has compiled information relevant to climate change and its impacts in an annotated bibliography with an emphasis on California. This annotated bibliography is intended as a source of current and emerging scientific information on climate change for environmental and public health agencies, the research community, non-government organizations, and the public.
