Causes of Rise in the Sea Water Level

            Many scientists have predicted by their research over the present condition that the glaciers are melting due to the global warming, which causes the Rise in the Sea Water Level, consequently many islands like Tebua Tarawa and Abanuea Island are already disappeared from the map of the world. The Rise in the Sea Water Level, due to the melting of the glaciers may be one of the reasons but there are still other factors also which are more responsible for the Rise in the Sea Water Level which is not yet studied, highlighted or exposed till today. If we go deeper for micro research; in that regard we will discover few more factors which reveals that the basic cause of the rise in the Sea Water Level. We should also remember that Glaciers do not melt during the winter seasons, whereas the water is continuously flowing down through the holes of the tube wells towards the sea throughout the year.

            In the above described facts there is confining impermeable layer between the aquifers. These impermeable layers are running thickness in up and down waves patterns instead of pure horizontal plates which stores water in there deeper laps. The rising parts of these confining layers were responsible for maintaining a water table in the upper unconfined aquifer.  There are millions of such issues and situations naturally built between the unconfined and confined aquifers under the ground of the earth surface those may contain millions of cubic kilometers “Stable Water”. Some water storages are very ancient and many have incoming water from one side and going out from either side. We have made millions of drilling holes in the bottom of such huge water storage over impermeable layer, beneath the earth surface consequently the huge water holding spaces/pots are punctured to create an alarming water crisis to such a large extend that the body of the earth fails to hold the water in itself which is flowing freely towards the sea through the shortcuts made by us, resulting the major cause of Rising of Sea Water Level. Hence, the steps taken by the Government of India in the direction for the remedy of the falling groundwater problem are still incomplete and will be fruitless.

           One more thing about the melting of the glaciers is still to understand for us. We have Glaciers in Asia are the glaciers of China, India, Pakistan, Nepal, and Tajikistan. Glaciers in Europe are the glaciers of Iceland, Norway, and Switzerland. Glaciers in South America are the glaciers of Argentina, Chile, Columbia, Peru, and Ecuador. Glaciers in North America are the glaciers of United States, Canada, Greenland and Mexico and the Glaciers of the New Zealand. These glaciers are melting due to the Global Warming, consequently there is a Rising in Sea Water Level as we have predicted till now.

           Now, let us compare the volume of glaciers (surface area & thickness) which is measureable; and the presence of very large volume of water in the aquifers in the uncertain height of the column below the total land area of the Earth Surface which is invisible and immeasurable. Obviously, the volume of the water released from the glaciers is much less than the water present below the earth surface. Let us have a look over the path of the water released from the melting glaciers towards the sea. The water released from the glaciers follows the path of the rivers and mostly percolated into the soil from the land area and the basin of the rivers and must get feeds up in the upper unconfined aquifer first. Due to melting of the glaciers, if the Sea Water Level could rise, then why the aquifer below the ground remains empty and the groundwater level is falling?

           We have predicted so far that due to immense pumping there is a Depletion of the Groundwater whereas, the situation must be opposite to it and we should have higher water table in the upper aquifers than before we had and the water level in the unconfined aquifers cannot be lowered; in the situation there are no holes in the impermeable layer; only by the immense pumping of the water for irrigation. The factual thing may be that the water present in unconfined and confined aquifers in a very large in quantity than the water released from the glaciers had lost underground holding places or aquifers and passes downwards through the tube well holes toward the sea. The water released from the glaciers also moves towards the sea through the lowest confined aquifers after passing through the first coming numerous holes in the impermeable layers instead of flowing through the upper aquifers.

         As predicted so far, that water from the melting glaciers raising the sea water level. We should also imagine a situation that if don’t have holes in the impermeable layers and the glaciers started melting “due some other reasons”. In that situation we must have our aquifers fully loaded with water and we can’t pump out that much of underground water that may results Depletion of Groundwater and serious drinking water crises when we have safe confining layers with no holes because the water from the glaciers will flow in the upper unconfined layers mostly.
