South Aral Sea Syr Darya, would be diverted in order to irrigate cotton and food crops in Kazakhstan and Uzbekistan. In 1986, due to an accelerated loss of water, the Aral Sea was split into northern and southern parts; the northern part is the current North Aral Sea. In 2007, the western basin had a salinity of 70 g/l and the eastern basin 100 g/l. Once the water level falls below the connecting channel (elevation 29 m), the salinities can be expected to diverge further. Under current conditions, the eastern basin may receive water from the Amu Darya in wet years, fluctuating in
Sea level rise (8%). The sea level will not rise uniformly everywhere on Earth, and it will even drop in some locations. Local factors include tectonic effects and subsidence of the land, tides, currents and storms. The rising trend is expected to continue for centuries. Because of long response times of the climate system, it has been estimated that each Celsius degree of temperature rise would trigger a sea level rise of approximately over the next 2,000 years. Sea level rises can considerably influence human populations in coastal and island regions and natural environments like marine ecosystems. Widespread coastal flooding would be expected
