Sea-Level Rise Gives Clue to Big Chill

Publication: National Geographic News   Date: December 6, 2004   View Article

Many scientists believe that about 8,200 years ago a glacial lake more than twice the size of the Caspian Sea poured into the North Atlantic and triggered a precipitous drop in temperature just as Earth was exiting the last ice age.

Climate modelers are keenly interested in accurately re-creating the conditions that drove this big chill, known as the 8.2 ka event, so they can predict if and when a similar scenario might occur in the future.
