摘要: The causal correlation or linkage between the East Asian Monsoon (EAM) intensity and rise/fall of Chinese dynasties recently proposed by high-resolution paleoclimate reconstructions is examined in detail. Aside from many exceptions to correlation, both instrumental historical climate records show strong spatial variations rainfall on annual-to-decadal scales over eastern China. relationship EAM also exhibits regional disparity. These observations suggest: (1) Taking paleo-proxy a single locality China imply changes drought/wetness as affect cultural political history fraught with uncertainty. (2) On scales, thesis that δ18O speleothems can be used proxy for strength lacks empirical underpinnings.
