• Coupled atmosphere-ice-ocean dynamics in Dansgaard-Oeschger events 

      Li, Camille; Born, Andreas (Peer reviewed; Journal article, 2018-11-10)
      The Dansgaard-Oeschger events of the last ice age are among the best studied abrupt climate changes, yet a comprehensive explanation is still lacking. They are most pronounced in the North Atlantic, where they manifest as ...
    • Eemian Greenland ice sheet simulated with a higher-order model shows strong sensitivity to surface mass balance forcing 

      Plach, Andreas; Nisancioglu, Kerim Hestnes; Langebroek, Petra; Born, Andreas; Le clec'h, Sebastien (Peer reviewed; Journal article, 2019-08-15)
      The Greenland ice sheet contributes increasingly to global sea level rise. Its history during past warm intervals is a valuable reference for future sea level projections. We present ice sheet simulations for the Eemian ...
    • Eemian Greenland SMB strongly sensitive to model choice 

      Plach, Andreas; Nisancioglu, Kerim Hestnes; Le clec'h, Sebastien; Born, Andreas; Langebroek, Petra; Guo, Chuncheng; Imhof, Michael; Stocker, Thomas F. (Peer reviewed; Journal article, 2018-10-19)
      Understanding the behavior of the Greenland ice sheet in a warmer climate, and particularly its surface mass balance (SMB), is important for assessing Greenland’s potential contribution to future sea level rise. The Eemian ...
    • GrSMBMIP: intercomparison of the modelled 1980-2012 surface mass balance over the Greenland Ice Sheet 

      Fettweis, Xavier; Hofer, Stefan; Krebs-Kanzow, Uta; Amory, Charles; Aoki, Teruo; Berends, Constantijn J.; Born, Andreas; Box, Jason E.; Delhasse, Alison; Fujita, Koji; Gierz, Paul; Goelzer, Heiko; Hanna, Edward; Hashimoto, Akihiro; Huybrechts, Philippe; Kapsch, Marie-Luise; King, Michaela D.; Kittel, Christoph; Lang, Charlotte; Langen, Peter L.; Lenaerts, Jan T.M.; Liston, Glen E.; Lohmann, Gerrit; Mernild, Jacob Sebastian Haugaard; Mikolajewicz, Uwe; Modali, Kameswarrao; Mottram, Ruth H.; Niwano, Masashi; Noël, Brice; Ryan, Jonathan C.; Smith, Amy; Streffing, Jan; Tedesco, Marco; Van de Berg, Willem Jan; Van den Broeke, Michiel; Van de Wal, Rodecrick S.; Von Kampenhout, Leo; Wilton, David; Wouters, Bert; Ziemen, Florian; Zolles, Tobias (Journal article; Peer reviewed, 2020)
      Observations and models agree that the Greenland Ice Sheet (GrIS) surface mass balance (SMB) has decreased since the end of the 1990s due to an increase in meltwater runoff and that this trend will accelerate in the future. ...
    • 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 ...
    • Melting of Northern Greenland during the last interglaciation 

      Born, Andreas; Nisancioglu, Kerim Hestnes (Peer reviewed; Journal article, 2012-11-05)
      Using simulated climate data from the comprehensive coupled climate model IPSL CM4, we simulate the Greenland ice sheet (GrIS) during the Eemian interglaciation with the three-dimensional ice sheet model SICOPOLIS. The ...
    • Ocean circulation and climate at the Eemian and last glacial inception 

      Born, Andreas (Doctoral thesis, 2010-09-24)
      Combining a hierarchy of climate models of varying complexity with marine proxy data, we show that the North Atlantic surface circulation played an important role for the climate of the Eemian and the last glacial inception. ...
    • A spatio-temporal reconstruction of sea-surface temperatures in the North Atlantic during Dansgaard-Oeschger events 5–8 

      Jensen, Mari Fjalstad; Nummelin, Aleksi; Nielsen, Søren B.; Sadatzki, Henrik; Sessford, Evangeline; Risebrobakken, Bjørg; Andersson, Carin; Voelker, Antje; Roberts, William H. G.; Born, Andreas (Journal article, 2017-08-24)
      Here we establish a spatio-temporal evolution of the sea-surface temperatures in the North Atlantic over Dansgaard Oeschger (DO) events 5–8 (c. 30–40 ka) using the proxy surrogate reconstruction method. Proxy data suggest ...
    • Was common Era glacier expansion in the Arctic Atlantic region triggered by unforced atmospheric cooling? 

      Haaga, Kristian Agasøster; Bilt, Willem van der; Born, Andreas (Peer reviewed; Journal article, 2019-08-05)
      The timing and causes of Common Era (CE) glacier growth in the Arctic Atlantic region remain elusive. There is mounting evidence of advances that predate the Little Ice Age (1250–1850 CE); this challenges the view that ...
