There is not enough water contained in the glaciers of antarctic and Greenland to raise the level of water to the point that is claimed by climate fear mongers even if it all melted.
The claim is that the oceans have risen by 25 cm/ 9 inches that would take a volume of water that is 80,000,000 cubic km/ 20,000,000 cubic miles the amount of water contained in Antarctica is only 26,676,363 cubic km/ 6,400,000 cubic miles. the amount of ice on Greenland is 76,000 and 100,000 square kilometres /29,000 and 39,000 sq mi, the total of both being 26,776,363 cubic km / 6,439,000 cubic Mi, far short of the amount of water needed to raise the sea level the 25cm/ 9inches already claimed.
The ice that is contained in the polar Ice caps has already displaced the ocean waters below it so even if it all melted it would not raise the ocean levels. so where is all the water that is going to flood us going to come from.
