Himalayan glaciers face haze threat, Study Say Soot ,Aerosols Over Indian Ocean Accelerating Melting
A huge haze of soot and other aerosols over the Indian Ocean could be playing a significant role in the melting of Himalayan glaciers, a study released on Thursday in `Nature' has claimed. But Indian scientists believe that the study comes from limited data collected over little time and leaves much to conjecture at the moment.
They are already undertaking long-term studies at the Indian Institute of Tropical Meteorology (IITM), Pune. The authors of the study, contrary to prevailing science, claim that the aerosol particles forming the haze are contributing to atmospheric warming just as other greenhouse gases do. They contend that the haze is warming the atmosphere enough to add to the glacial melts all over the Himalayas. The study's lead author had run into a major controversy on his earlier work, with Indian scientists claiming that correlating the presence of the haze specifically with Asian developing countries and recession of monsoon was an unscientific exaggeration and fraught with political implications.

``We believe that the conclusions drawn are based on very limited data (collected over Mauritius) collected over little period of time and there is much left unexplained about how aerosols intezract in atmosphere through the year all over the region. IITM is beginning long-term studies to understand these issues comprehensively,'' said K Krishna Kumar of IITM, Pune.
Lobbies in developed countries, including US, had used the earlier studies on the haze to suggest that rural populations in India and other Asian countries were also to blame for global warming (as the soot mostly originates from burning wood and other biomass). But noted Indian scientists, J Srinivasan and Sulochna Gadgil, had come out strongly at the time claiming that the study was faulty and exaggerated the impact such clouds had. They had provided evidence that similar haze existed all over the world and therefore to give the name `Asian Brown Haze' and claim that it was a unique situation was incorrect. The authors had rebutted it claiming that there were no holes in the study. At the same time, they had acknowledged that the haze was not unique to Asia but had been recorded all over the developed world as well. Source- TIMES NEWS NETWORK
