Air Pollution

From: Our Changing Climate: Assessing the Risks to California (pdf)

The air quality in most of California’s urban areas is already lower than the air quality standard. Southern California, in particular, has one of the most urbanized and most productive economies in the United States. But along with this comes the misfortune of having very high air pollution loadings. Additionally, Southern California’s air pollution is aggravated by ozone buildup, especially when warm sunny days with stagnant atmospheric conditions produce greater chances for photochemical reactions affecting trapped emissions. Ozone and particulate matter are often considered the most critical in adversely affecting human health, and have been implicated as being particularly harmful to children’s health.

Rising temperatures can further worsen the existing poor conditions which already result in staggering costs of $71 billion annually. Ailments such as asthma, other acute respiratory and cardiovascular diseases will only get more severe and affect more people.
