The natural ‘Himalayan aerosol factory’ can affect climate

by University of Helsinki, Dec 10, 2020 in WUWT


Large amounts of new particles can form in the valleys of the Himalayas from naturally emitted gases and can be transported to high altitudes by the mountain winds and injected into the upper atmosphere.

The emitted particles may eventually affect climate by acting as nuclei for cloud condensation. These new findings about particles formation and sources will contribute to a better understanding of past and future climate.

“To understand how the climate has changed over the last century we need to know as reliably as possible the natural atmospheric conditions before the industrialization,” says Associate Professor Federico Bianchi from the University of Helsinki’s Institute for Atmospheric and Earth System Research (INAR).

In order to do that scientists are looking for pristine locations around the world where human influence is minimal. An international group of researchers has now completed a comprehensive study at the Nepal Climate Observatory at Pyramid station, located in the proximity of the Everest base camp at 5050 m above sea level. There, they were able to investigate the formation of atmospheric particles far from human activities. The results were published today in the prestigious journal Nature Geoscience.

FOR THE FIRST TIME IN TWO DECADES, THICK SNOW LINGERS ON HIMALAYAN MOUNTAIN PASSES IN JULY

by Cap Alon, July 26, 2019 in Electroverse


Crazed environmentalists take note, the Himalayan mountain passes of Rohtang, Baralacha, Kunjum, Shikula are STILL blanketed in deep snow, in July!

Snow holding on until the end of July is incredibly rare on these passes, reports the The Statesman — in fact, it’s the first time in 20 years that it’s occurred, the packs are usually all-gone by the end of May.

Furthermore, heavy and record-breaking snow has been falling this week actually adding to the pack.

“The heavy accumulation of snow up to 4-5 feet on Rohtang, Baralacha, Kunjum, Shikula passes is certainly good for the environment in the Himalayas,” said Senior Scientific Officer at State Centre on Climate Change, Dr SS Randhawa.
