    • Arctic amplification under global warming of 1.5 and 2 °C in NorESM1-Happi 

      Graff, Lise Seland; Iversen, Trond; Bethke, Ingo; Debernard, Jens Boldingh; Seland, Øyvind; Bentsen, Mats; Kirkevåg, Alf; Li, Camille; Oliviè, Dirk Jan Leo (Peer reviewed; Journal article, 2019)
      Differences between a 1.5 and 2.0 ∘C warmer climate than 1850 pre-industrial conditions are investigated using a suite of uncoupled (Atmospheric Model Intercomparison Project; AMIP), fully coupled, and slab-ocean experiments ...

    • Can we use ice sheet reconstructions to constrain meltwater for deglacial simulations? 

      Bethke, Ingo; Li, Camille; Nisancioglu, Kerim Hestnes (Journal article, 2012)
      Freshwater pulses from melting ice sheets are thought to be important for driving deglacial climate variability. This study investigates challenges in simulating and understanding deglacial climate evolution within this ...

    • Equilibrium simulations of Marine Isotope Stage 3 climate 

      Guo, Chuncheng; Nisancioglu, Kerim Hestnes; Bentsen, Mats; Bethke, Ingo; Zhang, Zhongshi (Peer reviewed; Journal article, 2019)
      An equilibrium simulation of Marine Isotope Stage 3 (MIS3) climate with boundary conditions characteristic of Greenland Interstadial 8 (GI-8; 38 kyr BP) is carried out with the Norwegian Earth System Model (NorESM). A ...

    • Evaluating the biological pump efficiency of the Last Glacial Maximum ocean using d13C 

      Morée, Anne; Schwinger, Jörg; Ninnemann, Ulysses S; Jeltsch-Thommes, Aurich; Bethke, Ingo; Heinze, Christoph (Peer reviewed; Journal article, 2021)
      Although both physical and biological marine changes are required to explain the 100 ppm lower atmospheric pCO2 of the Last Glacial Maximum (LGM, ∼21 ka) as compared to preindustrial (PI) times, their exact contributions ...

    • NorCPM1 and its contribution to CMIP6 DCPP 

      Bethke, Ingo; Wang, Yiguo; Counillon, Francois Stephane; Keenlyside, Noel Sebastian; Kimmritz, Madlen; Fransner, Filippa; Samuelsen, Annette; Langehaug, Helene R.; Svendsen, Lea; Chiu, Ping-Gin; Passos, Leilane G.; Bentsen, Mats; Guo, Chuncheng; Gupta, Alok Kumar; Tjiputra, Jerry; Kirkevåg, Alf; Oliviè, Dirk Jan Leo; Seland, Øyvind; Vågane, Julie Solsvik; Fan, Yuanchao; Eldevik, Tor (Journal article; Peer reviewed, 2021)
      The Norwegian Climate Prediction Model version 1 (NorCPM1) is a new research tool for performing climate reanalyses and seasonal-to-decadal climate predictions. It combines the Norwegian Earth System Model version 1 (NorESM1) ...

    • Ocean Biogeochemical Predictions—Initialization and Limits of Predictability 

      Fransner, Filippa; Counillon, Francois; Bethke, Ingo; Tjiputra, Jerry; Samuelsen, Annette; Nummelin, Aleksi; Olsen, Are (Peer reviewed; Journal article, 2020)
      Predictions of ocean biogeochemistry, such as primary productivity and CO2 uptake, would help to understand the changing marine environment and the global climate. There is an emerging number of studies where initialization ...

    • Ocean biogeochemistry in the Norwegian Earth System Model version 2 (NorESM2) 

      Tjiputra, Jerry; Schwinger, Jörg; Bentsen, Mats; Morée, Anne; Gao, Shuang; Bethke, Ingo; Heinze, Christoph; Goris, Nadine; Gupta, Alok Kumar; He, Yan-Chun; Oliviè, Dirk Jan Leo; Seland, Øyvind; Schulz, Michael (Peer reviewed; Journal article, 2020)
      The ocean carbon cycle is a key player in the climate system through its role in regulating the atmospheric carbon dioxide concentration and other processes that alter the Earth's radiative balance. In the second version ...

    • Overview of the Norwegian Earth System Model (NorESM2) and key climate response of CMIP6 DECK, historical, and scenario simulations 

      Seland, Øyvind; Bentsen, Mats; Oliviè, Dirk Jan Leo; Toniazzo, Thomas; Gjermundsen, Ada; Graff, Lise Seland; Debernard, Jens Boldingh; Gupta, Alok Kumar; He, Yan-Chun; Kirkevåg, Alf; Schwinger, Jörg; Tjiputra, Jerry; Aas, Kjetil Schanke; Bethke, Ingo; Fan, Yuanchao; Griesfeller, Jan; Grini, Alf; Guo, Chuncheng; Ilicak, Mehmet; Karset, Inger Helene H.; Landgren, Oskar Andreas; Liakka, Johan; Moseid, Kine Onsum; Nummelin, Aleksi; Spensberger, Clemens; Tang, Hui; Zhang, Zhongshi; Heinze, Christoph; Iversen, Trond; Schulz, Michael (Peer reviewed; Journal article, 2020)
      The second version of the coupled Norwegian Earth System Model (NorESM2) is presented and evaluated. NorESM2 is based on the second version of the Community Earth System Model (CESM2) and shares with CESM2 the computer ...
