Dear E.K., The ocean does not have a uniform sea level height across the planet. Physical geography dictates this as do the gravitational forces that pull and push ocean water around the planet. Thermal expansion increases the volume of warm ocean water. So the Gulf of Mexico, which experiences higher rates of warming than the North Atlantic tends to be higher at its sea level than the neighbouring Caribbean Sea or Atlantic Ocean. And I am sure I don’t need to point out that the ocean is dynamic with tides raising and lowering sea level daily.

Please explain how the ocean rises in the Gulf of Mexico, but not over the entire ocean? After laughing at that, I just couldn’t finish the attic because it’s not worth taking seriously.

Have you considered beach and land erosion?
