During a sizeable chunk of the 20th century , the Soviet Union and the United States , along with their ally , were in a constant state of tension with a possible third world war conflict . That never happened , and the Cold War remain a catamenia of bitter contention , espionage , and counter - espionage .
Some of the declassify data is now being utilize in a completely different manner . alternatively of monitor possible soviet activities , images take by CIA spy satellites are being used to understand how much Himalayan glacier have exchange over the last several decades .
early on last year , research worker reported dataas far back as 1975 on the dramatic deoxyephedrine red ink of 650 Himalayan glacier . Now , a different squad has pushed some of the observations back to the 1960s , highlighting how the glaciers have thinned by more than 80 meters ( 260 pes ) , with some reaching more than 91 time ( 300 feet ) .
The determination was announced at theAmerican Geophysical Unionconference last month , where the work was presented by Dr Tobias Bolch , from the School of Geography and Sustainable Development at the University of St. Andrews in Scotland .
The team used declassified Corona and Hexagon undercover agent planet as well as modern - era satellite , such as Pleiades , GeoEye , TerraSAR - tenner , and ASTER . The loss over the last 60 geezerhood has been fleet , and has been accelerating since the 1980s .
Researchers have predicted that Mount Everest , the tall mountain on Earth , could be innocent of ice as before long as 2100 . The causes for the dramatic ice loss are multiple , let in increased level of soot in the air darkening the glacier and changes in hurry patterns . However , the clime crisis is the primary driver of the warming .
From 2000 to 2016 , the part has experienced a 1 ° C ( 1.8 ° F ) increase in temperature . Combined with the trends spotlight by the researchers , there is lilliputian estimable news for the region and beyond . Meltwater from the Himalayan glaciers is all-important for the well - being of approximately800 millionpeople who swear on it for drinking , farming , and energy production .
