"If the sea rises quickly enough, and there is not time for the waves to do their work, landscapes may be drowned entire."

"Only a few meters beneath sea level, and what was the land now lies below the destructive surf zone. A hundred meters below sea level, and even the most violent storm waves can scarcely be felt. So, let the sea flood in, with its level jumping by meters over centuries or decades – or perhaps even years – and there simply will not be time for this wave energy to erode the landscape."
