California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.

Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

Arrows denote winds at this level derived from meteorological analysis, showing that the HCN maximum is linked with the upper tropospheric Asian monsoon anticyclone. The finding, published online 25 March in the journal Science , provides additional evidence of the global nature of air pollution and its effects far above Earth’s surface.

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

The study also predicts that peak concentrations of dangerous airborne particles will increase in the San Joaquin Valley due to the effects of climate change on wind patterns. Our study reveals that climate change and regional air pollution are intertwined problems. Kleeman of UC Davis, lead author.
