One high - profile target, he says, should be reducing emissions of tiny soot particles, known as black carbon, that don't last long in the atmosphere but have an outsize impact on warming.

They point to recent scientific findings that black carbon has recently been identified as having twice the climate impact than was previously understood and now ranks as second most important climate pollutant.

Reductions in emissions of black carbon since the late 1980s, mostly from diesel engines as a result of air quality programs, have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a first - of - its - kind study — which Berkeley Lab participated in — examining the impact of black carbon on California's climate.

For example, pollutants such as black carbon (BC), organic carbon (OC), sulfur dioxide (SO2) or methane (CH4), affect human health both by altering climate as CO2 does (hereafter climate - health impacts) but also by more directly degrading air quality (hereafter composition - health impacts).
