Satellites Reveal the Scale of Himalayan Glacier Loss

Satellites Reveal the Scale of Himalayan Glacier Loss

Researchers looked at photos taken by a US surveillance program with ongoing spacecraft observations and found that melting in the region has multiplied in the course of the most recent 40 years. The study demonstrates that since 2000, these glaciers have been reducing by a normal of 0.5m every year. The analysts state that environmental change is the primary cause.

During the 1980s, a US spy program – codenamed Hexagon – propelled 20 satellites into space to secretly take photos of the Earth. The secretive pictures were taken on moves of film that were then dropped by the satellites into the air to collect mid-air bypassing military planes.

The images were declassified in 2011 and have been digitized by the US Geological Survey for researchers to use. Among the covert agent, photographs are the Himalayas – a zone for which verifiable information is rare.

By contrasting these photos and later satellite information from Nasa and the Japanese space organization (Jaxa), the analysts have had the option to perceive how the region has changed. Researchers state proceeded that losses will have a gigantic effect.

For the time being, the tremendous increment in meltwater could cause flooding. In the more extended term, a large number of individuals in the region who rely upon glacier meltwater during drought years could face extensive troubles.
