Cold War spy satellite images show dramatic ice loss in the last 40 years
  • The glaciers of the Himalayas are thawing and in the 21st century, they have lost twice as much ice as in the 20th century.
  • Scientists from Columbia University came to this conclusion after comparing images of the KH-9 satellites of the Cold War era with photographs of current satellites.
  • The authors of the research thought that the cause of melting glaciers may be associated with increases in temperature in the Himalayan areas.
  • In this regard, the data showed that temperatures have increased in this region around 1-degree centigrade during the investigated period.
  • The melting of glaciers decreases the future water supply of millions of people living in this area and threatens to cause flooding in the coastal cities of East Asia.
