Washington, Nov 7: A new study has linked the rise and fall of China’s ancient dynasties with monsoon cycles, with the weakening of the natural phenomenon proving to be the last straw for the kingdoms.
According to a report in National Geographic News, the study was led by researchers from the University of Minnesota and Lanzhou University in China.
The work rests on a 2,000-year-old record of monsoon activity preserved in the layers of stone in a 118-millimeter-long stalagmite found in Wanxiang Cave in Gansu Province, China.
The climate record was preserved in a stalagmite—a rock formed by mineral-rich waters dripping onto the cave floor year after year.
