We compare Pleistocene alpine glacier chronologies across North America with a comprehensive general circulation model using reconstructed ice sheet extents at peak glacial conditions during Marine Isotope Stage (MIS) 2 and MIS 4. The effect of continent-wide ice sheets on atmospheric circulation during MIS 2 led to warming in Beringia and cooling in the western US; less expansive ice sheets during MIS 4 resulted in weaker ice sheet modulation of atmospheric circulation. This led to preservation of MIS 4 moraines in Beringia due to limited MIS 2 glaciation (resulting in a MIS 2/4 moraine sequence) and overriding of MIS 4 moraines - for sites with existing chronologies - in the western United States during MIS 2 (resulting in a MIS 2/6 moraine sequence). Our results highlight how influential ice sheets are for regional climate conditions.","pubRank":"1"}],"site":[{"NOAASiteId":"22723","siteName":"Global","siteCode":null,"mappable":"N","locationName":"Geographic Region>Global","geo":{"geoType":"Feature","geometry":{"type":"POLYGON","coordinates":["-90","90","-180","180"]},"properties":{"southernmostLatitude":"-90","northernmostLatitude":"90","westernmostLongitude":"-180","easternmostLongitude":"180","minElevationMeters":null,"maxElevationMeters":null}},"paleoData":[{"dataTableName":"Tulenko2020","NOAADataTableId":"41257","earliestYear":66000,"mostRecentYear":21000,"timeUnit":"cal yr BP","earliestYearBP":66000,"mostRecentYearBP":21000,"earliestYearCE":-64050,"mostRecentYearCE":-19050,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/gcmoutput/tulenko2020/","urlDescription":"Data Folder","linkText":"Last Glacial Maximum and MIS4 Northern Hemisphere Climate Model Output","variables":[{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"sampling metadata>surface type","cvMaterial":null,"cvError":null,"cvUnit":"dimensionless","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"binary; 1 = Land; 0= Ocean","cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"earth system variable>temperature variable>temperature>air temperature","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":"2-month period>Jun-Jul","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"earth system variable>temperature variable>temperature>air temperature","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":"3-month period>Dec-Feb","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"earth system variable>temperature variable>temperature>air temperature","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":"annual","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"sampling metadata>collection elevation","cvMaterial":null,"cvError":null,"cvUnit":"length unit>meter","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"earth system variable>hydroclimatic variable>hydroclimate rate>precipitation","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":"2-month period>Jun-Jul","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"earth system variable>hydroclimatic variable>hydroclimate rate>precipitation","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":"3-month period>Dec-Feb","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"earth system variable>hydroclimatic variable>hydroclimate rate>precipitation","cvMaterial":null,"cvError":null,"cvUnit":"length unit>millimeter","cvSeasonality":"annual","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"earth system variable>hydroclimatic variable>hydroclimate rate>precipitation","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":"annual","cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"sampling metadata>longitude","cvMaterial":null,"cvError":null,"cvUnit":"angle unit>degree>degree east","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCLIMATIC MODELING","cvWhat":"sampling metadata>latitude","cvMaterial":null,"cvError":null,"cvUnit":"angle unit>degree>degree north","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null}],"NOAAKeywords":["earth science>paleoclimate>model>atmosphere model"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
