• Atlantic Meridional Overturning Circulation and δ13C Variability During the Last Interglacial 

      Kessler, Augustin; Bouttes, Nathaelle; Roche, Didier M.; Ninnemann, Ulysses S; Galaasen, Eirik Vinje; Tjiputra, Jerry (Journal article; Peer reviewed, 2020)
      The Atlantic Meridional Overturning Circulation (AMOC) is thought to be relatively vigorous and stable during Interglacial periods on multimillennial (equilibrium) timescales. However, recent proxy (δ13C benthic) reconstructions ...
    • Dynamics of spontaneous (multi) centennial‐scale variations of the Atlantic meridional overturning circulation strength during the last interglacial 

      Kessler, Augustin; Bouttes, Nathaelle; Roche, Didier M.; Ninnemann, Ulysses S; Tjiputra, Jerry (Peer reviewed; Journal article, 2020)
      Recent reconstructions of bottom water δ13C during the last interglacial (LIG) suggest short‐lived variability in the Atlantic meridional overturning circulation (AMOC). Spontaneous (multi) centennial‐scale variability of ...
    • Inequal responses of drylands to radiative forcing geoengineering methods 

      Park, Chang-Eui; Jeong, Su-Jong; Fan, Yuanchao; Tjiputra, Jerry; Muri, Helene; Zheng, Chunmiao (Peer reviewed; Journal article, 2019)
      Climate geoengineering has the potential to reduce global warming. However, the nonlinear responses of Earth's large‐scale circulation to climate geoengineering can exacerbate regional climate change, with potential ...
    • Interglacial instability of North Atlantic Deep Water ventilation 

      Galaasen, Eirik Vinje; Ninnemann, Ulysses S; Kessler, Augustin; Irvali, Nil; Rosenthal, Yair; Tjiputra, Jerry; Bouttes, Nathaelle; Roche, Didier M.; Kleiven, Helga Flesche; Hodell, David A. (Peer reviewed; Journal article, 2020)
      Disrupting North Atlantic Deep Water (NADW) ventilation is a key concern in climate projections. We use (sub)centennially resolved bottom water δ13C records that span the interglacials of the last 0.5 million years to ...
    • 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 ...
