South Asia Huge Brown Cloud Is Homemade

There is a huge, gunky brown cloud that lingers over south Asia and the Indian Ocean each winter. It’s been known to cause respiratory diseases and even cancers in India and China.

It has recently been discovered that a large percentage of the soot, from almost half to two-thirds, comes from burning biomass like wood and dung for cooking and heat, rather than from coal power plants. These particles only remain in the atmosphere for a few days or weeks at a time.

IMO: The answer could be to reduce biomass burning - and this should also reduce global warming and will probably save money by reducing the cost of health measures.
