Study suggests future climate changes to worsen air quality for >85% of China’s population; ~20k+ additional deaths each year

Green Car Congress

The team used a combination of climate, air quality, and epidemiological models to assess future air pollution deaths in a changing climate under Representative Concentration Pathway 4.5 (RCP and ozone exposure, respectively. and ozone in 2050 by factors of 1 and 3, respectively. C) and ozone (D) exposure are shown.

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. Our study reveals that climate change and regional air pollution are intertwined problems. Kleeman of UC Davis, lead author.

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

Green Car Congress

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. The team used airborne and ground-based measurements of organic aerosol (OA) in the Los Angeles (LA) Basin, California during May and June 2010.
