Scientists have used Cold War spy satellites to reveal the dramatic environmental changes on how the Himalayas are melting.
“They compared pictures collected by a US reconnaissance programme with recent satellite data to measure the extent of glacial melt,” a BBC report says.
Scientists believe the now-declassified images could help to show how other remote regions have changed over time.
According the report, the research was presented at the American Geophysical Union Fall meeting in San Francisco.
“This imagery will be getting used more and more,” said Josh Maurer from Columbia University in New York, according to BBC.
The images were taken by a United States spy satellite programme that went by the codename of Hexagon.
During the 1970s and 1980s, it launched 20 huge reconnaissance satellites into space, which secretly snapped areas of interest below.
The images were taken on rolls of film, which were then dropped by the satellites, and collected mid-air by passing military planes.
The information collected was declassified in 2011 and is now being digitised by the US Geological Survey (USGS) for scientists to use, the report added.
