These overlooked, shorter - term pollutants — mostly from burning wood and kerosene and from driving trucks and cars — cause more localized warming than once thought, the authors of the report say.They contend there should be a greater effort to attack this type of pollution for faster results.For decades, scientists have concentrated on carbon dioxide, the most damaging greenhouse gas because it lingers in the atmosphere for decades.

You may wonder why the government finds the need to pursue such action since 1) U.S. carbon dioxide emissions have already topped out and have generally been on the decline for the past 7 - 8 years or so (from technological advances in natural gas extraction and a slow economy more so than from already - enacted government regulations and subsidies); 2) greenhouse gases from the rest of the world (primarily driven by China) have been sky - rocketing over the same period, which lessens any impacts that our emissions reduction have); and 3) even in their totality, U.S. carbon dioxide emissions have a negligible influence on local / regional / global climate change (even a immediate and permanent cessation of all our carbon dioxide emissions would likely result in a mitigation of global temperature rise of less than one - quarter of a degree C by the end of the century).

Methane is a powerful greenhouse gas 25 times more potent than carbon dioxide, and the ongoing global warming driven by carbon dioxide will inevitably force it out of its frozen reservoirs and into the atmosphere to amplify the warming.
