One of the current mysteries of climate science surrounds the widely accepted evidence that during the planet’s most recent past natural warm period, about 128,000 to 117,000 years ago, global sea levels peaked as high as 6 to 9 meters (20 or 30 feet) higher than today. And, during that so-called last interglacial, temperatures were just 1or 2 degrees C (1.8 to 3.6 F) warmer than those of preindustrial times—marks we may surpass by century’s end, if not sooner. Such a deluge could have been produced only by collapses of the Greenland and/or Antarctic ice sheets. If that happens now, it will drown much of the human world. Yet, at least so far, models of future sea level rise generally hover around a meter or so within the next 100 years. What are we missing, and how much should it scare us?
