Study Proposes New Strategy to Stem Global Warming

An influential expert on global warming who for nearly 20 years has pressed countries to cut emissions of carbon dioxide and other heat-trapping gases now says the emphasis on carbon dioxide may be misplaced. Instead, he and a team of scientists have concluded that the quickest way to slow warming is to cut other such greenhouse gases first.
This strategy could help policy makers overcome a fundamental conflict in the debate over global warming: carbon dioxide, the main heat-trapping gas in the air, is an unavoidable byproduct of burning fossil fuels like coal and oil -- and combustion of fossil fuels is the foundation of industrial societies.
The expert, Dr. James E. Hansen, and his colleagues conclude in a new analysis that the warming seen in recent decades has been caused mainly by other heat-trapping emissions -- methane, chlorofluorocarbons, black particles of diesel and coal soot and compounds that create the ozone in smog -- which are easier to control than carbon dioxide, with many of them already on the decline.
