When you write the program to prove your preconceived notion its no wonder they get these results. More struggle for their 15 minutes of shame (and another Federal Grant).
Between the pelting of the Earth with Ice from space and the escape of moisture from out atmosphere, the AMOUNT of water on the Earth hasn’t changed much in billions of years.
What DOES change is the ground. It moves, constantly. The change in sea levels , for instance, in New Orleans is not due to a rise in sea level, but a lowering of the ground.
There are new islands popping up out of the ocean while at the same time there are islands which disappear beneath the waves.
If it was due to sea level change, both things could not occur at the same time. Yet they do.
