    • 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 ...

    • Observed and simulated temperature extremes during the recent warming hiatus 

      Sillmann, Jana; Donat, M. G.; Fyfe, J. C.; Zwiers, F. W. (Journal article; Peer reviewed, 2014)
      The discrepancy between recent observed and simulated trends in global mean surface temperature has provoked a debate about possible causes and implications for future climate change projections. However, little has been ...
