The waters rising hundreds of meters would take thousands of years, not hundreds.
False.
Example of this being a farce:
Fossilization can occur in one hundred years flat. A&E had a show about strange realities, showcasing a miner hat in a California gold mine was found petrified. Nature does not always follow man-made routine.
Water can rise in a few minutes, or a few centuries. Thousands of years? Yes, but also in decades. An example of this is the town of Denison Texas. About 11 miles from it, there exists a town, that was a population of around 4,300 people as of 1964. It is now 45 feet beneath a lake, caused by rising water from an underground fissure. Ocean trenches would have miles long fissures. Melting icecaps, coupled with weather and water NON-solubility due to contaminants, could and do, expedite rising waters.
You lose.
