• Assessing metrics of climate change: Current methods and future possibilities 

      Fuglestvedt, Jan S.; Berntsen, Terje; Godal, Odd; Sausen, Robert; Shine, Keith P.; Skodvin, Tora (CICERO Report;2001:04, Research report, 2001)
      With the principle of comprehensiveness embedded in the UN Framework Convention on Climate Change (Art. 3), a multi-gas abatement strategy with emphasis also on non-CO2 greenhouse gases as targets for reduction and control ...
    • Climate strategy for Africa 

      Hernes, Helga; Dalfelt, Arne; Berntsen, Terje; Holtsmark, Bjart; Næss, Lars Otto; Selrod, Rolf; Aaheim, H. Asbjørn (CICERO Report;1995:03, Research report, 1995)
      1. General observations Africa south of the Sahara is probably the most vulnerable region when it comes to the impact and consequences of climate changes. Yet the African continent runs a serious risk of being marginalized ...
    • Climatic effects of NOx emissions through changes in tropospheric O3 and CH4: A global 3D model study 

      Fuglestvedt, Jan S.; Berntsen, Terje; Isaksen, Ivar S. A.; Mao, Huiting; Liang, Xin-Zhong; Wang, Wei-Chyung (CICERO Report;1997:03, Research report, 1997)
      As a result of chemical processes in the atmosphere, emissions of NOx can both damp and enhance the greenhouse effect. The two most important effects of NOx in this context are increased concentrations of tropospheric ozone ...
    • Effects of anthropogenic emissions on tropospheric ozone and its radiative forcing 

      Berntsen, Terje; Isaksen, Ivar S. A.; Fuglestvedt, Jan S.; Myhre, Gunnar; Larsen, T. Alsvik; Stordal, Frode; Freckleton, R. S.; Shine, Keith P. (CICERO Report;1997:02, Research report, 1997)
      Tropospheric ozone changes since pre-industrial times due to changes in emissions have been calculated by the University of Oslo global 3-D photochemical model. The radiative forcing caused by the increase in ozone has ...
    • Exploring distribution of commitments: A follow-up to the Berlin Mandate 

      Torvanger, Asbjørn; Berntsen, Terje; Fuglestvedt, Jan S.; Holtsmark, Bjart; Ringius, Lasse; Aaheim, H. Asbjørn (CICERO Report;1996:03, Research report, 1996)
      The study reviews and analyzes some major issues that must be considered when defining principles for distributing commitments to reduce greenhouse gas emissions for countries belonging to the Organization for Economic ...
    • Luftfart og klima - En oppdatert oversikt over status for forskning på klimaeffekter av utslipp fra fly 

      Lund, Marianne Tronstad; Aamaas, Borgar; Berntsen, Terje; Fuglestvedt, Jan S. (CICERO Report;2016:05, Research report, 2016)
      Denne rapporten gir en oppdatert oversikt over hvordan og i hvilken grad de ulike utslippene fra flytrafikk påvirker klima basert på den nyeste forskningen. For å forstå den totale klimaeffekten av luftfart er det viktig ...
    • Responses in tropospheric O3, OH and CH4 to changed emissions of important trace gases 

      Fuglestvedt, Jan S.; Berntsen, Terje; Isaksen, Ivar S. A. (CICERO Report;1993:04, Research report, 1993)
      A two-dimensional (altitude vs. latitude) photochemical/transport model of the global troposphere is applied to study the effects of changed emissions of NOx, CH4, CO2 and NMHC on the levels of O3, OH and CH4. On a mass ...
