Droughts destroyed Mesopotamia
A study has shown that the ancient civilisation of Mesopotamia collapsed due to years of drought resulting from climate change. A team from Germany's T bingen University analysed carbon isotopes in 1,037 samples of barley grains (12,000 to 2,500 years old) from 33 locations in west Asia and Africa to ascertain if they had enough water while growing. The results were then compared with modern samples from the same regions. The comparison showed that droughtlike situation prevailed during the last years of the civilisation.
