Greenhouse gases modulate the strength of millennial-scale subtropical rainfall, consistent with future predictions
Millennial-scale East Asian monsoon variability is closely associated with natural hazards through long-term variability in flood and drought cycles. Therefore, exploring what drives the millennial-scale variability is of significant importance for future prediction of extreme climates. Here we pres...
