Indicators of Climate Change in California

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.

Recent Research on Climate Change in California: A bibliography

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.

Human Health Impacts 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.

Indicators of Climate Change: Impacts on California Tribes

A key goal for the next update to the report is to include tribal impacts among those presented in the report. OEHHA has begun to engage California tribes to help us achieve this goal.

Jun 18, 2020: Adverse Pregnancy Outcomes Linked to Climate Change
Higher rates of preterm birth, low birth weight and stillbirth are linked to increased heat, ozone and fine particulate matter, according to a meta-analysis released today and co-authored by scientists at the California Office of Environmental Health Hazard Assessment (OEHHA). The analysis summarizes the evidence from 68 studies and includes 32.8 million U.S. births.
Aug 22, 2019: Recent Research on Climate Change
The Office of Environmental Health Hazard Assessment (OEHHA) continually monitors the scientific literature, publications of research organizations, governmental entities and academia, and other information sources to support the preparation of a periodic report presenting indicators of climate change in California.
