TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Preliminary global mean CO 2 concentrations in February 2014 were 398.06 Ozone formation. Scenario A2 and RCP 8.5.

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.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. Total anthropogenic GHG emissions were the highest in human history from 2000 to 2010 and reached 49 (±4.5)

Study finds modifying urban form may be a strategy to reduce air pollution

Green Car Congress

They used satellite-based measurements of urban form and nitrogen dioxideO 2 (n) to explore relationships between urban form and air pollution for a global data set of 1,274 cities. For example, recent estimates suggest that globally, approximately 25% of ambient urban PM 2.5 is attributable to motor vehicles. —Bechle et al.
