New Delhi, Dec 29 (PTI) Dust and soot contribute as much or more than greenhouse gases to the melting of glaciers in the Himalayas, experts said here today. "Apart from other causes such as changing fuel patterns, increasing aviation operations and noise pollution, dust is a major factor for environment deformation," Ramesh P Singh Affiliate Facult, Chapman University, said at a seminar organised by United Nation Environment Programme (UNEP) here.
"Increasing level of aerosol in atmosphere is main cause of pollution and melting glaciers. Pre-monsoon rains, warming, variability in temperature trends and dusty rain are result of the aerosol which is increasing," Ritesh Gautam, a researcher with NASA said.
The experts, who made presentations on changes in Himalayan environment, favoured a multi-lateral long-term programme to preserve ecology in the high-altitude region. In the Himalayan region, the soot and dust primarily drift north and east from factories, farms and other sources in the subcontinent.
"Another big reason of pollution is increasing number of power plants. These plants release a big amount of carbon waste.
When this carbon emission reacts with dust, a thick layer of pollution is produced which can be seen on our glaciers," Singh said.
