Throughout the climate swings of the Pleistocene, the ice sheet that covered North America—one larger even than modern Antarctica—did not merely shrink in response to a few degrees of warming, writes Peter Brannen in Ends of the World, it exploded: “Rather than slowly dwindling over thousands of years, these continents of ice sometimes violently disintegrated in spectacles that unfolded over mere centuries. In one rapid collapse 14,000 years ago, called Meltwater Pulse 1A, three Greenlands’ worth of ice fell into the sea in icy flotillas, sending sea level soaring 60 feet.”
