ATTN: sea-level rise is about the thickness of two pennies stacked one on top of the other, around 3 millimeters per year. At this rate, sea level would rise barely 9 inches by 2100, meaning New York City, average elevation 10 meters, would be flooded in a little over 3,000 years. The point is this is a slow-motion process and something we can deal with. < >
Maximum global mean sea level during the last interglacial period (129,000 to 116,000 years ago) was, for several thousand years, at least 5 m higher than present.
