Aral Sea Continues to Shrink

Aral Sea Continues to Shrink - NASA:

"Throughout the first half of the twentieth century, the Aral Sea was the world’s fourth-largest lake. In the 1960s, the Soviet Union began a massive irrigation project in what are now Kazakhstan, Uzbekistan, and Turkmenistan, diverting water from the rivers that feed the Aral Sea to irrigate farmland. As its water levels dropped, the lake began splitting into smaller pieces: the Northern (Small) Aral Sea and the Southern (Large) Aral Sea. The Southern Aral Sea further split into eastern and western lobes. The Earth Observatory’s World of Change: Evaporation of the Aral Sea feature tracks this process over the past decade."
