Far below the Dead Sea, between Israel, Jordan and Palestinian territories, researchers have found evidence of a drought that has no precedent in human experience.
From depths of 300 metres below the landlocked basin, drillers brought to the surface a core that contained 30 metres of thick, crystalline salt: evidence that 120,000 years ago, and again about 10,000 years ago, rainfall had been only about one fifth of modern levels.
The cause in each case would have been entirely natural. But in the region where human civilisation began, already in the grip of its worst drought for 900 years, it is a reminder of how bad things could get and a guide to how much worse human-induced climate change could become.
Dead Sea evidence of unprecedented drought is warning for future
