However, whether those δ18O records are a proxy of temperature or monsoon Received in revised form 15 October 2020 intensity has remained a great controversy. Generally, ice core δ18O records from non-monsoon and Accepted 2 November 2020 transition regions indicate temperature, but ice core and speleothem δ18O records from monsoon regions Available online 17 November 2020 have been regarded as proxies for monsoon intensity or precipitation.
