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). The RCPs were chosen to represent a broad range of climate outcomes, based on a literature review. 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
