Soot from diesel exhausts and
the burning of wood, agricultural waste and dung for heating and cooking causes
an estimated two million premature deaths a year, particularly in the poorest
countries. Scientists say that concerted action on these substances can reduce
global temperatures by 0.5 degrees Celsius by 2050 and prevent millions of cases
of lung and heart disease by 2030. There is no way to effectively address a
climate change without reducing carbon dioxide, the most dangerous, prevalent,
and persistent greenhouse gas. It stays in the atmosphere for hundreds of years.
