Persistent high latitude amplification of the Pacific Ocean over the past 10 million years. Nature Communications 13, 7310 (2022). https://doi.org/10.1038/s41467-022-35011-z # Abstract: While high latitude amplification is seen in modern observations, paleoclimate records, and climate modeling, better constraints on the magnitude and pattern of amplification would provide insights into the mechanisms that drive it, which remain actively debated. Here we present multi-proxy multi-site paleotemperature records over the last 10 million years from the Western Pacific Warm Pool (WPWP) – the warmest endmember of the global ocean that is uniquely important in the global radiative feedback change. These sea surface temperature records, based on lipid biomarkers and seawater Mg/Ca-adjusted foraminiferal Mg/Ca, unequivocally show warmer WPWP in the past, and a secular cooling over the last 10 million years. Compiling these data with existing records reveals a persistent, nearly stationary, extratropical response pattern in the Pacific in which high latitude (~50°N) temperatures increase by ~2.4° for each degree of WPWP warming. This relative warming pattern is also evident in model outputs of millennium-long climate simulations with quadrupling atmospheric CO2, therefore providing a strong constraint on the future equilibrium response of the Earth System. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: OCE-1602905, 2217530 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: the International Ocean Discovery Program # Grant: Post-Expedition Activity (PEA) award of the US Science Support Program #--------------------------------------- # Site_Information # Site_Name: IODP U1488 # Location: Western Pacific Ocean # Northernmost_Latitude: 2.04 # Southernmost_Latitude: 2.04 # Easternmost_Longitude: 141.75 # Westernmost_Longitude: 141.75 # Elevation_m: -2604 #--------------------------------------- # Data_Collection # Collection_Name: IODP U1488 TEX86 SST Liu2022 # First_Year: 9746000 # Last_Year: 10000 # Time_Unit: calendar year before present # Core_Length_m: # Parameter_Keywords: biomarkers, reconstruction # Notes: #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## sitename sample identification,,,,,paleoceanography,,,C,site name ## Hole sample identification,,,,,paleoceanography,,,C,Hole ## Core sample identification,,,,,paleoceanography,,,C,Core ## Section sample identification,,,,,paleoceanography,,,C,Section ## cm_top depth at sample end,,,centimeter,,paleoceanography; climate reconstructions,,,N, ## cm_bottom depth at sample start,,,centimeter,,paleoceanography; climate reconstructions,,,N, ## depth_mbsf depth,,,meter,,paleoceanography; climate reconstructions,,,N,shipboard meters below sea floor ## age_kaBP age,,,calendar kiloyear before present; climate reconstructions,,paleoceanography,,,N, ## GDGT-0 glycerol dialkyl glycerol tetraether,,,peak area integral,,paleoceanography,,high-performance liquid chromatography; mass spectrometry ,N,peak area of GDGT-0 ## GDGT-1 glycerol dialkyl glycerol tetraether,,,peak area integral,,paleoceanography,,high-performance liquid chromatography; mass spectrometry ,N,peak area of GDGT-1 ## GDGT-2 glycerol dialkyl glycerol tetraether,,,peak area integral,,paleoceanography,,high-performance liquid chromatography; mass spectrometry ,N,peak area of GDGT-2 ## GDGT-3 glycerol dialkyl glycerol tetraether,,,peak area integral,,paleoceanography,,high-performance liquid chromatography; mass spectrometry ,N,peak area of GDGT-3 ## Cren glycerol dialkyl glycerol tetraether,,,peak area integral,,paleoceanography,,high-performance liquid chromatography; mass spectrometry ,N,peak area of crenarchaeol ## Cren' glycerol dialkyl glycerol tetraether,,,peak area integral,,paleoceanography,,high-performance liquid chromatography; mass spectrometry ,N,peak area of crenarchaeol regioisomer ## TEX86 tetraether index of 86 carbon atoms,sediment,,dimensionless,,paleoceanography,,,N,Following Schouten et al.
