The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Click to enlarge. Both near-term and long-term strategies are essential, the report concludes.

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 Tg CO 2 eq) in 2011. Tg CO 2 eq) in 2011.

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.

Aviation climate change impacts pathway. In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. Credit: ACS, Stratton et al.
