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. Click to enlarge.

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

Green Car Congress

They found that reductions in ground ozone during this 35-year period resulted in $600 million in increased production annually by the early 2010s. Davis and his colleagues chose to concentrate on perennials because of the long-term investment they represent and the fact that California is a major supplier of this type of produce.

NASA-led study identifies unprecedented depletion of stratospheric ozone layer above Arctic

Green Car Congress

A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The same ozone-loss processes occur each winter in the Arctic.

Field study finds soot particles absorb significantly less sunlight than predicted by models; climate models may be overestimating warming by BC

Green Car Congress

Although viewed as a potential target in the global effort to reduce climate change, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science.

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. Day, Lynn M.
