Soot Matters

Soot 'makes global warming worse'

The effects of soot in changing the climate are more than most scientists acknowledge, two US researchers say.
In the Proceedings of the National Academy of Sciences, they say reducing atmospheric soot levels could help to slow global warming relatively simply.
They believe soot is twice as potent as carbon dioxide, a main greenhouse gas, in raising surface air temperatures.
