OSLO (Reuters) - Cutting soot and other air pollutants could help "buy time" in the fight against climate change, a senior U.S. official said on Tuesday as seven nations joined a Washington-led plan.
Air pollution, from sources ranging from wood-fired cooking stoves in Africa to cars in Europe, may be responsible for up to six million deaths a year worldwide and is also contributing to global warming, the U.N. Environment Programme (UNEP) said.
