Global study links daily exposure to ozone pollution to increased risk of death

Green Car Congress

Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight. Recent reviews suggest that 80% of the world’s population in urban areas are exposed to air pollution levels above the WHO threshold. g/m 3 (WHO), 120 ?g/m g/m 3 (European Union directive), 140 ?

Study using satellite data finds rate of urban growth much greater than previously thought

Green Car Congress

An international team of researchers has used satellite images to map urban growth between 1985 and 2015. Urban area dynamics during 1985–2015 at the global and continent scales. They then extracted cells from the two fusion maps that changed from non-urban in 1985 to urban in 2015.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.
