• Asynchronous Antarctic and Greenland ice-volume contributions to the last interglacial sea-level highstand 

      Rohling, E.J.; Hibbert, F.D.; Grant, K.M.; Galaasen, Eirik Vinje; Irvali, Nil; Kleiven, Helga Flesche; Marino, G.; Ninnemann, Ulysses S; Roberts, A.P.; Rosenthal, Y.; Schulz, H.; Williams, F.H.; Yu, J. (Peer reviewed; Journal article, 2019-11-06)
      The last interglacial (LIG; ~130 to ~118 thousand years ago, ka) was the last time global sea level rose well above the present level. Greenland Ice Sheet (GrIS) contributions were insufficient to explain the highstand, ...
    • An international intercomparison of stable carbon isotope composition measurements of dissolved inorganic carbon in seawater 

      Cheng, Lin; Normandeau, Claire; Bowden, Roxane; Doucett, Richard; Gallagher, Barbora; Gillikin, David P; Kumamoto, Yuichiro; McKay, Jennifer L; Middlestead, Paul; Ninnemann, Ulysses S; Nothaft, Daniel; Dubinina, Elena O.; Quay, Paul; Reverdin, Gilles; Shirai, Kotaro; Mørkved, Pål Tore; Theiling, Bethany; Geldern, Robert; Wallace, D. W. R. (Peer reviewed; Journal article, 2019)
      We report results of an intercomparison of stable carbon isotope ratio measurements in seawater dissolved inorganic carbon (δ 13C‐DIC) which involved 16 participating laboratories from various parts of the world. The ...
    • A low climate threshold for south Greenland Ice Sheet demise during the Late Pleistocene 

      Irvali, Nil; Galaasen, Eirik Vinje; Ninnemann, Ulysses S; Rosenthal, Yair; Born, Andreas; Kleiven, Helga Flesche (Peer reviewed; Journal article, 2020-01-07)
      The Greenland Ice Sheet (GIS) has been losing mass at an accelerating rate over the recent decades. Models suggest a possible temperature threshold between 0.8 and 3.2 °C, beyond which GIS decline becomes irreversible. The ...
