Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. Short-lived climate pollutants (SLCPs) make up about 12% of GHG emissions, but strong actions to reduce them could help reduce global warming by as much as 40%.

The researchers believe the measurements will substantially impact the understanding of atmospheric chemistry mechanisms—in particular, in the more rapid formation of secondary aerosols, important in the formation of local smog as well as in global climate change. —Welz et al. —Marston (2012).

Black carbon—soot—is a global-warming agent the immediate control of which will slow the demise of Arctic sea ice faster than will control of any other global-warming agent, Jacobson said. The first found that globally-emitted CO 2 increases US air pollution deaths by about 1,000 each year per 1.8 °F, Mark Jacobson.

SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change. CO 2 remains in the atmosphere for up to a century.

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. The global economic crisis 2007/2008 only temporarily reduced emissions. WG III Summary for Policymakers.

Global emissions were growing by 1.1% The developing and least-developed economies, 80% of the world’s population, accounted for 73% of the global growth of emissions in 2004. In 2008, the minimum ice extent was 9% greater than in 2007, but still the second lowest on record.

In order to achieve the 2008 Ozone National Ambient Air Quality Standards set by US EPA, CARB estimates that the South Coast Air Basin alone (including Los Angeles) will need an 80% reduction in NO x emissions by 2031. CARB said it looked forward to continued cooperation with the federal agencies on this long-term effort.
