Here, we measure Mg/Ca ratios on individual foraminifera to reconstruct east Pacific subsurface temperature variability, a proxy for ENSO variability, across the last 25,000 years, including the millennial-scale events of the last deglaciation. Combining these data with proxy system model output reveals divergent ENSO responses to Northern Hemisphere stadials: enhanced variability during Heinrich Stadial 1 (H1) and reduced variability during the Younger Dryas (YD) relative to the Holocene. H1 ENSO likely intensified through meltwater-induced changes to ocean/atmospheric circulation, a response observed in models, but the lack of a similar response during the YD challenges model simulations. We suggest the tropical Pacific mean state during H1 primed ENSO for larger fluctuations under meltwater forcing, whereas the YD mean state likely buffered against it.","pubRank":"1"}],"site":[{"NOAASiteId":"58376","siteName":"MV1014-02-09MC","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>Eastern Pacific Ocean","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["-.693833","-85.33325"]},"properties":{"southernmostLatitude":"-0.693833","northernmostLatitude":"-0.693833","westernmostLongitude":"-85.33325","easternmostLongitude":"-85.33325","minElevationMeters":"-2452","maxElevationMeters":"-2452"}},"paleoData":[{"dataTableName":"MV1014-02-09MC Trace Metal and Temp Recon Glaubke2024","NOAADataTableId":"52366","earliestYear":1970,"mostRecentYear":1970,"timeUnit":"cal yr BP","earliestYearBP":1970,"mostRecentYearBP":1970,"earliestYearCE":-20,"mostRecentYearCE":-20,"coreLengthMeters":null,"dataTableNotes":"Data collected from seven discrete climate horizons: the late Holocene (1.97 ka), the early Holocene (8.49 and 10.1 ka), the Younger Dryas (12.3 ka), the Bølling-Allerød (13.4 ka), Heinrich Stadial 1 (14.9 ka), and the Last Glacial Maximum (19.7 ka)","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleocean/pacific/glaubke2024/glaubke2024-09mc.txt","urlDescription":"NOAA Template File","linkText":"MV1014-02-09MC Trace Metal Data and Subsurface Water Temperature Reconstruction","variables":[{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"sampling metadata>sample identification","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"Time slice name: LH = late Holocene;
