The caption points out the release of a glacial lake in North America as a proximate cause of the rapid sea level rise in Europe. I'm familiar with the release from Lake Bonneville 14,500 years ago which caused the Bonneville Flood. Geologists estimate that Lake Bonneville was lowered 350 ft over the course of a year. A total of 1,200 CUBIC MILES of water were discharged at a max rate of 1 million cubic meters per second (speed of 70 mph!). But, given that the surface area of the oceans is 139 million square miles, even that vast amount of water would raise global sea level only by a half-inch. So what North American glacial lake release are they talking about?

Likely the proglacial lakes whose remnants today are the Great Lakes, along with Great and Lesser Slave lakes. There were also significant proglacial lakes in Poland and western Siberia.

Probably ancient lake Missoula among many others; geologists are only beginning to piece together such events during the Big Melt. The Lake Missoula flood repeatedly released awesome amounts of water and created the formerly mysterious Scablands in Washington state. But it was just one event out of many worldwide.
