From The Independent:引用：Governments could slow global warming dramatically, and buy time to avert disastrous climate change, by slashing emissions of one of humanity’s most familiar pollutants – soot – according to Nasa scientists. A study by the space agency shows that cutting down on the pollutant, which has so far been largely ignored by climate scientists, can have an immediate cooling effect – and prevent hundreds of thousands of deaths from air pollution at the same time.
Governments have long experience in acting against soot.
Cutting its emissions has a virtually instantaneous effect, because it rapidly falls out of the atmosphere, unlike carbon dioxide which remains there for over a hundred years. And because soot is one of the worst killers among all pollutants, radical reductions save lives and so should command popular and political support.12 1 月 2009 6:15 上午 #4577匏名
Hi, i am completely agreed with you that by reducing soot we can reduce global warming which is affecting all the world right now.
