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.

Dust, ozone and carbon can accumulate in valleys and basins in California and other Western states. When you buy a product at Wal-Mart, it has to be manufactured somewhere. The product doesn’t contain the pollution, but creating it caused the pollution. —Steve Davis, UC Irvine Earth system scientist and co-author.

The results highlight the early challenges in a nascent sector of climate science and could have implications for regulatory efforts to reduce the production of black carbon, or soot, by curbing the burning of fossil fuels.

A study led by researchers at UC Berkeley has found that diesel exhaust forms about seven times more secondary organic aerosols (SOA) than gasoline exhaust for the same mass of unburned fuel emissions and, given emission factors, can be expected to form 15 times more SOA than gasoline per liter of fuel burned.
