A fundamental change between regimes occurred during deglaciation through a series of millennial reoccurrences of century-scale changes in the East Asian monsoon (EAM) climate. These abrupt events centered at 17.0, 15.9, 15.5, 14.7, 13.5, 13.9, 13.3, 12.1, 11.5, and 10.7 14C ka correlate well with the millennial-scale events in the Santa Barbara Basin and the Arabian Sea, i.e. a relationship between EAM and El Niño/Southern Oscillation systems. The abrupt increases in summer monsoon imply enhanced heat transport from low-latitude sea area to the midlatitude/high-latitude land area. The phase relationship between events of EAM and ice sheet may reflect a faster EAM response and a slower ice sheet response to the insolation change. A far-reaching conclusion is that the EAM might have triggered the Northern Hemisphere deglaciation.","pubRank":"1"}],"site":[{"NOAASiteId":"19183","siteName":"17940-2","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>North Pacific Ocean","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["20.12","117.38"]},"properties":{"southernmostLatitude":"20.12","northernmostLatitude":"20.12","westernmostLongitude":"117.38","easternmostLongitude":"117.38","minElevationMeters":"-1727","maxElevationMeters":"-1727"}},"paleoData":[{"dataTableName":"17940-1_2","NOAADataTableId":"4271","earliestYear":41132,"mostRecentYear":14,"timeUnit":"14C yr BP","earliestYearBP":44627,"mostRecentYearBP":0,"earliestYearCE":-42677,"mostRecentYearCE":1950,"coreLengthMeters":null,"dataTableNotes":"Data precision: d18O- ±0.08 ¿ PDB.
