UN study: Soot, smog curbs quick way to combat warming

BONN - Tighter limits on soot and smog provide a quick and easy way to fight global warming while protecting human health and raising crop output, a UN study said on Tuesday.
It outlined 16 measures, ranging from plugging leaky gas transport pipelines to improving wood burning stoves, to limit "black carbon" -- soot -- methane and tropospheric ozone, which is a greenhouse gas that is a big component of smog.
