Preventing Sea Rise

The 1st idea is to build water pumping stations at the south pole and have water pumped from the oceans and deposited into the middle of the Antarctic continent where it would turn to ice and solidify and thus lower the sea level.

My 2nd idea is to dig artificial rivers and estuary's in unpopulated areas of Russia, or Canada for example or even countries of Africa or Australia, anywhere really. The artificial rivers and estuary's will be extremely wide and after they have been dug the flood gates so to speak will be opened and water from the oceans and seas will be allowed to flow along these artificial rivers and estuarys and thus lower sea level.

My 3rd idea is to literally dig out a huge deep chunk of land in the middle of Greenland or Russia, line it with plastic coating and fill the enormous trench with sea water and then cover it over.

My 4th idea is to dig large amounts of Earth from the sea bed and then deposit that soil on land and build a large mountain from it, as the undersea soil was taken away there would be more volume under the sea for the water to fill. So basically imagine digging out soil and creating a grand canyon style trench in the sea bed.
