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 snow, which accumulates and over time forms glacial ice. Much of this precipitation began as water vapor evaporated from the ocean surface. To a first approximation, the same amount of water appeared to return to the ocean in icebergs and from ice melting at the edges. Scientists previously had estimated which is greater, ice going in or coming out, called the glacier mass balance, important because a nonzero balance causes changes in global sea level. The rate of ice loss is accelerating. In terms of heat content, it is the world ocean that dominates the atmospheric climate. The oceans store
