      Global climate models (GCMs) disagree with other lines of evidence on the rapid adjustments of cloud cover and liquid water path to anthropogenic aerosols. Attempts to use observations to constrain the parameterizations ...
    • Reducing uncertainties in decadal variability of the global carbon budget with multiple datasets 

      Li, Wei; Ciais, Philippe; Wang, Yilong; Peng, Shushi; Broquet, Grégoire; Ballantyne, Ashley P.; Canadell, Josep G.; Cooper, Leila; Friedlingstein, Pierre; Le Quéré, Corinne; Myneni, Ranga B.; Peters, Glen Philip; Piao, Shilong; Pongratz, Julia (Journal article; Peer reviewed, 2016)
      Conventional calculations of the global carbon budget infer the land sink as a residual between emissions, atmospheric accumulation, and the ocean sink. Thus, the land sink accumulates the errors from the other flux terms ...

      We apply a physical climate storyline approach to an autumn flood event in the West Coast of Norway caused by an atmospheric river to demonstrate the value and challenges of higher spatial and temporal resolution in ...
    • Science as a "fixed point" Quantification and boundary objects in international climate politics 

      Lahn, Bård; Sundqvist, Göran (Journal article; Peer reviewed, 2017)
      Our understanding of climate change is dominated by quantified scientific knowledge, with science and politics usually seen as operating separately and autonomously from one another. By investigating a particular fact box ...
    • Seizing policy windows: Policy Influence of climate advocacy coalitions in Brazil, China, and India, 2000?2015 

      Aamodt, Solveig; Stensdal, Iselin Phoebe (Peer reviewed; Journal article, 2017)
      What drives the development of climate policy? Brazil, China, and India have all changed their climate policies since 2000, and single-case analyses of climate policymaking have found that all three countries have had ...
    • Sensitivity of black carbon concentrations and climate impact to aging and scavenging in OsloCTM2-M7 

      Lund, Marianne Tronstad; Berntsen, Terje Koren; Samset, Bjørn Hallvard (Peer reviewed; Journal article, 2017)
      Accurate representation of black carbon (BC) concentrations in climate models is a key prerequisite for understanding its net climate impact. BC aging and scavenging are treated very differently in current models. Here, ...
    • Sharing a quota on cumulative carbon emissions 

      Raupach, Michael R.; Davis, Steven J.; Peters, Glen Philip; Andrew, Robbie; Canadell, Josep G.; Friedlingstein, Pierre; Jotzo, Frank; Le Quéré, Corinne (Peer reviewed; Journal article, 2014)
      Any limit on future global warming is associated with a quota on cumulative global CO2 emissions. We translate this global carbon quota to regional and national scales, on a spectrum of sharing principles that extends from ...

      Westskog, Hege; Aase, Tor Halfdan; Standal, Karina; Tellefsen, Sølvi (Journal article; Peer reviewed, 2020)
      Sharing goods and services has been promoted as fostering more sustainable consumption. In this paper, we explore sharing in a middle-class neighbourhood in a Norwegian city. We ask what influences and frames neighbours’ ...
