The average sea level is reported to have risen in recent years, as reported by such data as the frequency that the Thames barrage has had to be raised to avoid upstream flooding. Have there been any scientific studies that investigate the causes for this evidence other than temperature and atmospheric Carbon Dioxide ? In many areas of the world, rainfall is sufficiently sparse that an agricultural system cannot be supported. In recent years, aquifers have been utilised to provide an alternative supply of fresh water for irrigation and civilisation. If you consider the fact that the ultimate fate of this water is destined for the ocean, as the aquifers are not significantly replenished, is this significant enough to provide a cummulative effect of a global rise in sea levels. Is this rise wholly a result of meltwater from Permafrost and melted Polar ice ? There is extraction of water from aquifers around the world, including aquifers in the Middle East, The Sahara (particularly Libya), and the large Ogallala aquifer in Central USA. The Aral Sea on the Kazakhstan / Uzbekistan border is a shadow of its former natural self. Could the extraction of these waters lead to a significant rise in global sea levels ? Could a solution be to better utilise the fresh water that is available to civilisations around the world ? Much of the water from the Aral Sea is poorly used for Cotton cultivation. Could a solution to counter sea level rise be to prevent water running off the land and into the sea ? Could a large lake be formed in a remote area to offset the extra water being added to the oceans ? Could this also provide a water supply for civilisations ? The enlargening of the Sahara and the desertification of the Sahel could be offset by forming a large freshwater lake in North Africa from waters flowing down the Nile. In the recent past associated with the Holocene Period, Hudson Bay was much larger, and formed a much larger body of water known as the Tyrrell Sea. There is substantial scientific consensus to confirm that this was linked to sea level changes.
