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 of the climate system. Of course, when the ocean gains heat the water expands and this represents a component of global sea-level rise. The thermal expansion of water increases with temperature and pressure of the water. Hence, cold Arctic Ocean water will expand less for a given increase in temperature compared to warm tropical water. Because different climate models have slightly different patterns of ocean heating, they do not agree fully on the predictions for the contribution of ocean heating on sea level rise. The large volume of ice on the Antarctic continent stores around 70% of the world's fresh
