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.
