Past sea level has varied by somewhat more than a hundred metres. This is primarily due to the growth and decay of ice sheets (mostly in the northern hemisphere) with water evaporated from the sea. The Mediterranean Basin's gradual growth as the Neotethys basin, begun in the Jurassic, did not suddenly affect ocean levels. While the Mediterranean was forming during the past 100 million years, the average ocean level was generally 200 metres above current levels. However, the largest known example of marine flooding was when the Atlantic breached the Strait of Gibraltar at the end of the Messinian Salinity Crisis about 5.2
Red Sea–Dead Sea Water Conveyance used by Jordan and the Palestinians. Concerns regarding Israel's nuclear facility are irrelevant as the Dimona reactor is cooled by heavy, not normal (i.e., light) water. Under the current proposal, water sufficient only to prevent the Dead Sea from dehydrating will flow through the system, preventing salt water flow into wells. The World Bank study recommended re-routing the conduit to avoid the geological faults of the Araba Valley. Red Sea–Dead Sea Water Conveyance The Red Sea–Dead Sea Conveyance, sometimes called the Two Seas Canal, is a planned pipeline that runs from the coastal city of Aqaba by the Red Sea
