Ancient Lake-Burst Flooded Atlantic, Slowed Ocean Currents
| Quote From Source: | Near the end of the last Ice Age 8,000 years ago, an ice dam on North America's eastern coast broke, releasing a torrent of fresh water seven times more voluminous than all the Great Lakes combined. It all rushed into the Atlantic Ocean over the course of only a few months.
At around the same time, ocean circulation worldwide slowed to a crawl, plunging Europe into a second ice age that lasted centuries.
Normally, ocean currents function like a global conveyer belt, ferrying warm, buoyant water from the southern hemisphere into the far north, where it loses its heat and sinks to the bottom because cold water is denser than warm water.
