  • Climate change is quickening the disappearance of the Aral Sea.
  • 2
  • Once a single body of water, the lake now exists in pieces in Kazakhstan and Uzbekistan.
  • 3
  • Many years ago, it was one of the world's largest inland bodies of water.
  • 4
  • But, that changed substantially over the last century.
  • 5
  • The Aral has shrunk to less than 25 percent of its former size.
  • 6
  • Engineering projects and agricultural programs are to blame for much of the lake's early losses.
  • 7
  • Now, climate change is adding to the destruction.
  • 8
  • Summers in the area are longer and hotter.
  • 9
  • Winters are shorter and colder.
  • 10
  • The area lacks water supplies.
  • 11
  • And experts say much of the water that does exist is too salty to support plant life.
  • 12
  • The Aral is fed by rivers that heavily depend on glacial melt.
  • 13
  • For many years, it held many fish, supporting a fishing industry.
  • 14
  • The area brought in thousands of migrants for jobs in the past, also.
  • 15
  • Today, a few remaining towns sit quiet along the Aral's dry seabed.
  • 16
  • Dust storms often pass through.
  • 17
  • In the 1920s, the Soviet government began to empty the sea to provide water to crops like cotton.
  • 18
  • By the 1960s, it was half its former size.
  • 19
  • By 1987, the Aral's level was so low it divided into two bodies of water: the northern and southern seas.
  • 20
  • The United Nations Development Program calls the destruction of the Aral Sea "the most staggering disaster of the 20th century."
  • 21
  • It points to the Aral's loss as the cause of desertification, drinking water shortages, and worsening health conditions, among others.
  • 22
  • National governments, international aid organizations, and local efforts have made attempts to save the sea, including dams and plant growth projects.
  • 23
  • But experts say climate change has only quickened the dying of the Aral, and will continue to worsen local peoples' suffering.
  • 24
  • The loss of much of the Aral Sea caused dust storms to blow through towns.
  • 25
  • They spread toxic chemicals from a former weapons testing center and farms into the lungs and eyes of local peoples.
  • 26
  • The U.N. says this has increased rates of diseases related to breathing and cancer.
  • 27
  • A U.N. report says dust storms, rising world temperatures, and wind are destroying the glaciers on which the feeder rivers depend.
  • 28
  • The remaining water is getting saltier and evaporating faster.
  • 29
  • The report warns that melting ice and changing river flows may further cause problems for water supply and food supply.
  • 30
  • Hydropower plants could suffer.
  • 31
  • In Uzbekistan, Adilbay and his friends fish in the Aral's remaining waters.
  • 32
  • The fish are small and few.
  • 33
  • The 62-year-old holds his arms wide to demonstrate how big the Aral fish used to be.
  • 34
  • "Now there is nothing," he said.
  • 35
  • As the water disappeared, a nearby fish processing plant closed.
  • 36
  • Adilbay's friends and relatives moved to Kazakhstan looking for new jobs.
  • 37
  • There, fisherman Serzhan Seitbenbetov and others find success.
  • 38
  • In an hour, he caught a hundred fish, some 2 meters long.
  • 39
  • "Now all the villagers make good money being fishermen," he said.
  • 40
  • That is the result of an $86 million dam project led by Kazakhstan, with assistance from the World Bank.
  • 41
  • It was completed in 2005.
  • 42
  • Known as the Kokaral Dam, it saves and gathers water from the Syr Darya River.
  • 43
  • The dam performed better than expected, leading to an increase of over 3 meters in water levels after seven months.
  • 44
  • That helped restore local fisheries and caused an increase in clouds and rainstorms in the local area, the World Bank says. Population grew.
  • 45
  • But it could not replicate life before the water started drying up, said Sarah Cameron.
  • 46
  • She is a professor at the University of Maryland who is writing a book about the Aral.
  • 47
  • "It does not support the same amount of people and the fishing industry in the same way," Cameron said.
  • 48
  • Uzbekistan's restoration efforts have been mixed in success.
  • 49
  • The government has not undertaken large projects like the Kokaral.
  • 50
  • Instead, the country planted trees and other plants to help prevent erosion and slow dust storms.
  • 51
  • The discovery of oil and natural gas in the Aral's former seabed led to the building of gas production sites.
  • 52
  • Experts say that shows that Uzbekistan has little interest in restoration..
  • 53
  • Kate Shields is a professor of environmental studies at Rhodes College in the American state of Tennessee.
  • 54
  • "While there has been some restoration," she said, "there was a sort of acceptance that ... the sea was not coming back."
  • 55
  • Government officials from Uzbekistan and Kazakhstan did not answer questions from the Associated Press about restoration efforts, the lack of water, and the effects of climate change.
