Climate / Environmental Health
Climate change is already affecting the health and well-being of Californians. Climate change threatens and harms human health through changes in environmental exposures, including more extreme heat and other severe weather events, worsened air quality, more frequent wildfires and smoke, increases in allergens, altered environmental conditions that foster the spread of infectious diseases, and other direct and indirect pathways. The resulting human health impacts include, but are not limited to, increased number of cases of heat-related illness and death, more air pollution-related cardiovascular and respiratory disease events, increased injury and loss of life due to wildfires, severe storms, and flooding, increased occurrences of water-borne and vector-borne diseases (such as Lyme Disease or Zika virus), and stress and mental trauma from loss of livelihoods, property loss, and displacement.
While all Californians are affected by climate change, populations facing racial and health inequities, or systemic differences in racial and health status that are preventable and unfair, are impacted disproportionately. Certain population groups also have greater susceptibility to the health effects of climate change because of their proximity and sensitivity to climate-related environmental exposures and hazards.

Air Quality Index
The American Lung Association (ALA) assigns grades A-F to counties (A=1; B=2; C=3; D=4; F=5), based on average annual number of days that ozone levels exceeded U.S. standards during the three year measurement period. The five-point grading scale was used for the distribution (Green = <2; Yellow = 2 - 3; Red = >3). The air quality data is collected by the EPA and summarized by the ALA.
