Is it just a coincident or deliberate when NASA says that soot & dust are damaging Himalayas?
The study, which looked at soot and dust concentrations in South Asia between 2000 and 2007 as well as air circulation patterns during that period, was made available at the Dec 7-18 climate summit here.
It says much of the soot - as well as dust - travels along air currents from southern Asia to the Tibetan plateau, where it accumulates. It also accumulates along the southern slopes of the Himalayas.
With a detailed numerical model, the study reinforces what Veerabhadran Ramanathan of the Scripps Institution of Oceanography in San Diego, California, has been saying - the soot and dust contribute as much to warming in the Himalayas as other greenhouse gases.
This is because the black soot and grey dust accumulate on the white snow and ice of th ...more
