In Biblical Land, Searching for Droughts Past and Future
Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.
