[Geology2] Cores Samples Reveal When Dead Sea 'Died'_



Cores Samples Reveal When Dead Sea 'Died'_

> Sediments drilled from beneath the Dead Sea reveal that this most
> remarkable of water bodies all but disappeared 120,000 years ago. It is a discovery
> of high concern say scientists because it demonstrates just how dry the
> Middle East can become during Earth's warm phases. In such ancient times, few
> if any humans were living around the Dead Sea.
>
> Today, its feed waters are intercepted by large populations and the lake
> level is declining rapidly. "The reason the Dead Sea is going down is
> because virtually all of the fresh water flowing into it is being taken by the
> countries around it," said Steve Goldstein, a geochemist at Columbia
> University's Lamont-Doherty Earth Observatory, US.
>
> "But we now know that in a previous warm period, the water that people are
> using today and are relying upon stopped flowing all by itself. That has
> important implications for people today because global climate models are
> predicting that this region in particular is going to become more arid in the
> future," he told BBC News.
