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). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

The climate change benefit is estimated for a given year (2050) and human health and crop benefits are. Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. National benefits of the CH 4 plus BC measures versus the reference scenario.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases.
