    • Aerosol absorption has an underappreciated role in historical precipitation change 

      Samset, Bjørn Hallvard (Peer reviewed; Journal article, 2022)
      Precipitation change has proven notoriously hard to simulate consistently between global climate models. Aerosol induced shortwave absorption over the historical era is also poorly constrained in both observations and ...

    • African biomass burning affects aerosol cycling over the Amazon 

      Holanda, Bruna A.; Franco, Marco A.; Walter, David; Artaxo, Paulo; Carbone, Samara; Cheng, Yafang; Chowdhury, Sourangsu; Ditas, Florian; Gysel-Beer, Martin; Klimach, Thomas; Kremper, Leslie A.; Krüger, Ovid O.; Lavric, Jost V.; Lelieveld, Jos; Ma, Chaoqun; Machado, Luiz A. T.; Modini, Robin L.; Morais, Fernando G.; Pozzer, Andrea; Saturno, Jorge; Su, Hang; Wendisch, Manfred; Wolff, Stefan; Pöhlker, Mira L.; Andreae, Meinrat O.; Pöschl, Ulrich; Pöhlker, Christopher (Peer reviewed; Journal article, 2023)
      Smoke from vegetation fires affects air quality, atmospheric cycling, and the climate in the Amazon rain forest. A major unknown has remained the quantity of long-range transported smoke from Africa in relation to local ...

    • Anthropogenic sulfate aerosol pollution in South and East Asia induces increased summer precipitation over arid Central Asia 

      Xie, Xiaoning; Myhre, Gunnar; Shindell, Drew; Faluvegi, Gregory; Takemura, Toshihiko; Voulgarakis, Apostolos; Shi, Zhengguo; Li, Xinzhou; Xie, Xiaoxun; Liu, Heng; Liu, Xiaodong; Liu, Yangang (Peer reviewed; Journal article, 2022)
      Precipitation has increased across the arid Central Asia region over recent decades. However, the underlying mechanisms of this trend are poorly understood. Here, we analyze multi-model simulations from the Precipitation ...

    • The Arctic has warmed nearly four times faster than the globe since 1979 

      Rantanen, Mika; Karpechko, Alexey Yu.; Lipponen, Antti; Nordling, Kalle; Hyvärinen, Otto; Ruosteenoja, Kimmo; Vihma, Timo Pekka; Laaksonen, Ari (Peer reviewed; Journal article, 2022)
      In recent decades, the warming in the Arctic has been much faster than in the rest of the world, a phenomenon known as Arctic amplification. Numerous studies report that the Arctic is warming either twice, more than twice, ...

    • Atmospheric concentrations of black carbon are substantially higher in spring than summer in the Arctic 

      Jurányi, Zsófia; Zanatta, Marco; Lund, Marianne Tronstad; Samset, Bjørn Hallvard; Skeie, Ragnhild Bieltvedt; Sharma, Sangeeta; Wendisch, Manfred; Herber, Andreas (Peer reviewed; Journal article, 2023)
      A key driving factor behind rapid Arctic climate change is black carbon, the atmospheric aerosol that most efficiently absorbs sunlight. Our knowledge about black carbon in the Arctic is scarce, mainly limited to long-term ...

    • Climate benefit of a future hydrogen economy 

      Hauglustaine, Didier; Paulot, Fabien; Collins, William; Derwent, Richard; Sand, Maria; Boucher, Olivier (Peer reviewed; Journal article, 2022)
      Hydrogen is recognised as an important future energy vector for applications in many sectors. Hydrogen is an indirect climate gas which induces perturbations of methane, ozone, and stratospheric water vapour, three potent ...

    • A multi-model assessment of the Global Warming Potential of hydrogen 

      Sand, Maria; Skeie, Ragnhild Bieltvedt; Sandstad, Marit; Krishnan, Srinath; Myhre, Gunnar; Bryant, Hannah; Derwent, Richard; Hauglustaine, Didier; Paulot, Fabien; Prather, Michael; Stevenson, David (Peer reviewed; Journal article, 2023)
      With increasing global interest in molecular hydrogen to replace fossil fuels, more attention is being paid to potential leakages of hydrogen into the atmosphere and its environmental consequences. Hydrogen is not directly ...

    • Observations suggest that North African dust absorbs less solar radiation than models estimate 

      Adebiyi, Adeyemi A.; Huang, Yue; Samset, Bjørn Hallvard; Kok, Jasper F. (Peer reviewed; Journal article, 2023)
      Desert dust accounts for a large fraction of shortwave radiation absorbed by aerosols, which adds to the climate warming produced by greenhouse gases. However, it remains uncertain exactly how much shortwave radiation dust ...

    • Steady global surface warming from 1973 to 2022 but increased warming rate after 1990 

      Samset, Bjørn Hallvard; Zhou, C.; Fuglestvedt, Jan S.; Lund, Marianne Tronstad; Marotzke, J.; Zelinka, M.D. (Peer reviewed; Journal article, 2023)
      The change in global mean surface temperature is a crucial and broadly used indicator of the evolution of climate change. Any decadal scale changes in warming rate are however obfuscated by internal variability. Here we ...

    • Trends in atmospheric methane concentrations since 1990 were driven and modified by anthropogenic emissions 

      Skeie, Ragnhild Bieltvedt; Hodnebrog, Øivind; Myhre, Gunnar (Peer reviewed; Journal article, 2023)
      The atmospheric methane trend is not fully understood. Here we investigate the role of the main sink, the main natural source, and anthropogenic emissions on the methane growth rate over the last three decades using numerical ...
