      The radiative forcing of the aerosol–radiation interaction can be decomposed into clear-sky and cloudy-sky portions. Two sets of multi-model simulations within Aerosol Comparisons between Observations and Models (AeroCom), ...
    • Frequency of extreme precipitation increases extensively with event rareness under global warming 

      Myhre, Gunnar; Alterskjær, Kari; Stjern, Camilla Weum; Hodnebrog, Øivind; Marelle, Louis; Samset, Bjørn Hallvard; Sillmann, Jana; Schaller, Nathalie; Fischer, Erich; Schulz, Michael; Stohl, Andreas (Journal article; Peer reviewed, 2019)
      The intensity of the heaviest extreme precipitation events is known to increase with global warming. How often such events occur in a warmer world is however less well established, and the combined effect of changes in ...
