Abrupt climate change at ~ 2800 Yr BP

The stalagmite record from peninsular India indicates an abrupt climate change, characterized by the decline of Indian summer monsoon around 2800 yr BP. In addition, the decline of ISM around 2800 yr BP coincides with a sudden rise in the atmospheric Δ14C,indicative of reduced solar activity. This period (~2800 yr BP) is widely reported as the cold European climate associated with ice debris events in the North Atlantic (also known as the Iron Age Cold Epoch), which were reportedly forced by low solar activity.
