1WHAT CHANGES WERE PRESENTED BY NASA IMAGES?

This is the picture of the Aral Sea in August 2000. It is a gigantic lake standing between Kazakhstan and Uzbekistan and had been the fourth-largest lake of the world. In 1960s, the Soviet government planned to sidetrack the water of the Aral Lake for the irrigation of the surrounding plains. The NASA Images highlights this sidetrack by the black outline, thus representing the water edge in 1960.

In 2014, this Aral Sea had vanished away. It was not only a habitat for the fishes but also regulated the weather and the temperature. With the disappearing of the lake, it gets very hot and dry during the summers, also affecting the crops.

This picture is of the Alaska Aialik Bay as it used to be during the mid 20th century. It was taken during the summers, as it was not very hot during the summers for over 50-60 years ago. It also shows the Pederson’s Glacier, a white chunk of ice, in the background.

This image is of the same bay during August 2005. By this time, only a little white point was left of the Pederson Glacier.  It had left more than 1 mile. In the meanwhile, the sea began to rise and the coast sank thus forming a damp lagoon.

The image is of Lake Urmia, situated in Iran as in April 2016. The scientists guessed that during the last 14 years, about 70% of the lake’s surface area had disappeared. It still looked like a huge water body.

Within three months, the lake turned blood red. The surface area covered by water had reduced thus changing the ecosystem of the lake and letting more bacteria and algae taking over. These creatures had converted the lake into a blood red form.
