UCI-led study finds California’s strict air quality regulations have helped farmers

Green Car Congress

Researchers at the University of California, Irvine and other institutions have conducted a statistical analysis of pollution exposure and yields from 1980 to 2015 on a key sector making up about 38% of the state’s total agricultural output: perennial crops such as almonds, grapes, nectarines, peaches, strawberries and walnuts.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. We already know that climate change will bring us increased forest fires, shorter winters, hotter summers and impact our water supply.

Berkeley study identifies diesel as main source of vehicular secondary organic aerosols

Green Car Congress

Organic aerosol (OA) in the atmosphere is detrimental to human health and represents a highly uncertain forcing of climate change. The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone.
