This study investigates changes in monsoon precipitation in East Asia under a 2°C interglacial warming scenario. Researchers reconstructed temperature and precipitation data from north-central China over the past 800,000 years, revealing that the average precipitation increase under a 2°C warming is approximately half that estimated from the last glacial-to-interglacial warming. This difference is attributed to the amplification of climate change by ice volume variations. Analysis of interglacial data suggests a 100 mm increase in monsoon precipitation on the Chinese Loess Plateau under a 2°C warming scenario. The study highlights the importance of comparing different interglacial periods to better understand future warming scenarios. The results show that the monsoon precipitation response to warming is influenced by both temperature and ice volume changes. The study also demonstrates that the past interglacial warming, characterized by limited ice cover in Greenland, offers a closer analog for future warming, providing more reliable estimates for model simulations. The findings suggest that monsoon precipitation over northwestern China will increase by approximately 99.2 mm under a 2°C interglacial warming scenario. The study provides valuable insights into the response of monsoon precipitation to warming, which is crucial for understanding and predicting future climate changes.This study investigates changes in monsoon precipitation in East Asia under a 2°C interglacial warming scenario.
