Abrupt Holocene Indian Summer Monsoon failures: A primary response to solar activity?
Knowledge of the millennial abrupt monsoon failures is critical to understanding the related causes. Here, we extracted proxy indices of Indian Summer Monsoon (ISM) intensity during the early to mid-Holocene, from peat deposits at Lake Xihu, in southwestern China. There are a series of abrupt, mille...

Knowledge of the millennial abrupt monsoon failures is critical to understanding the related causes.
