This evolution includes gradual trends of warming and cooling driven by tectonic processes on time scales of 105to 107 years, rhythmic or periodic cycles driven by orbital processes with 104- to 106-year cyclicity, and rare rapid aberrant shifts and extreme climate transients with durations of 103 to 105 years. Here, recent progress in defining the evolution of global climate over the Cenozoic Era is reviewed. We focus primarily on the periodic and anomalous components of variability over the early portion of this era, as constrained by the latest generation of deep-sea isotope records. We also consider how this improved perspective has led to the recognition of previously unforeseen mechanisms for altering climate.","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":"Global isotope Zachos2001","NOAADataTableId":"34955","earliestYear":65000000,"mostRecentYear":0,"timeUnit":"cal yr BP","earliestYearBP":65000000,"mostRecentYearBP":0,"earliestYearCE":-64998050,"mostRecentYearCE":1950,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/contributions_by_author/zachos2001/zachos2001.txt","urlDescription":"Original Data and Full Metadata","linkText":"zachos2001.txt","variables":[{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"sampling metadata>notes","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"foraminiferal genus measured","cvFormat":"Character","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 13C","cvMaterial":"biological material>organism>foraminifer>benthic foraminifer","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil","cvSeasonality":null,"cvDetail":"averaged","cvMethod":null,"cvAdditionalInfo":"5 point running average","cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>foraminifer>benthic foraminifer","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil","cvSeasonality":null,"cvDetail":"averaged","cvMethod":null,"cvAdditionalInfo":"5 point running average","cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 13C","cvMaterial":"biological material>organism>foraminifer>benthic foraminifer","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>foraminifer>benthic foraminifer","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil","cvSeasonality":null,"cvDetail":"corrected","cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>million years ago","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":null},{"cvDataType":"PALEOCEANOGRAPHY","cvWhat":"sampling metadata>notes","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"site","cvFormat":"Numeric","cvShortName":null}],"NOAAKeywords":["earth science>paleoclimate>paleocean"]}]}]}],"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}
