Climate Change: Aerosols Heat Up, Nature
 









Excerpts: Solid particles suspended in the atmosphere have long played second
fiddle to greenhouse gases as agents of climate change. A study of atmospheric
heating over the Indian Ocean could provoke a rethink.  In the fourth assessment
report of the Intergovernmental Panel on Climate Change (IPCC), released earlier
this year, the effect on climate of aerosols - small, suspended particles of
varying composition, size and shape - since the start of the industrial era was
estimated to be about 20% of that of greenhouse gases.
