Question raised in Lok Sabha on Effects of Pollution on Himalayan Glaciers, 13/12/2019. Black Carbon is emitted into the atmosphere as a by-product of combustion processes such as fossil fuel, vegetation burning, industrial effluents, motor vehicle and air craft exhausts.

Question raised in Rajya Sabha on Steps to Preserve the Himalayan Glaciers, 02/07/2019. The National Centre for Polar and Ocean Research (NCPOR)under the Ministry of Earth Sciences (MoES) has undertaken studies in the Western Himalaya in Chandra basin in Lahaul-Spiti (Himachal Pradesh) since 2013.

New observations confirm continued rapid warming in the Arctic, driving many of the changes underway in the region, including loss of sea ice and glacier coverage, as well as changes in terrestrial and marine ecosystems.

Glaciers in the Satluj river basin in western Himalaya are likely to lose 33% of their area by 2050 and 81% by the end of the century, under Representative Concentration Pathway - RCP 8.5 scenario, based on the output from CNRM-CM5 and GFDL-CM3 climate models respectively.

If current trends continue, some of the lower-altitude glaciers of the tropical Andes could lose between 78 and 97% of their volume by the end of the century, reducing the region’s available freshwater resources. These alarming data are from the Water Atlas launched by UNESCO during the COP24 in Katowice (Poland) in december 2018.

Continuous seismic observations across the Ross Ice Shelf reveal ubiquitous ambientresonances at frequencies >5 Hz. These firn-trapped surface wave signals arise through wind and snowbedform interactions coupled with very low velocity structures.

Over the last 50 years more than 90 % of the excess heat excess accumulated in the climate system because of greenhouse gas emissions has been stored in the ocean. The rest has been warming the atmosphere and continents, and melting sea and land ice.

Shimla: As experts shared a stage to discuss impacts of climate change on mountain ecosystems, it emerged that it’s high time to come up with mitigation strategies to sustain livelihood of farmers

Deposition and accumulation of light-absorbing carbonaceous aerosol on glacier surfaces can alter the energy balance of glaciers. In this study, 2 years (December 2014 to December 2016) of continuous observations of carbonaceous aerosols in the glacierized region of the Mt. Yulong and Ganhaizi (GHZ) basin are analyzed. The average elemental carbon (EC) and organic carbon (OC) concentrations were 1.51±0.93 and 2.57±1.32 µg m−3, respectively.
