• Multi-model effective radiative forcing of the 2020 sulfur cap for shipping 

      Skeie, Ragnhild Bieltvedt; Byrom, Rachael; Hodnebrog, Øivind; Jouan, Caroline; Myhre, Gunnar (Peer reviewed; Journal article, 2024)
      New regulations of sulfur emissions from shipping were introduced in 2020, reducing emissions of SO2 from international shipping by ∼ 80 %. As SO2 is an aerosol precursor, this drop in emissions over the ocean will weaken ...
    • Recent reductions in aerosol emissions have increased Earth’s energy imbalance 

      Hodnebrog, Øivind; Myhre, Gunnar; Jouan, Caroline; Andrews, Timothy; Forster, Piers M.; Jia, Hailing; Loeb, Norman G.; Oliviè, Dirk Jan Leo; Paynter, David; Quaas, Johannes; Raghuraman, Shiv Priyam; Schulz, Michael (Peer reviewed; Journal article, 2024)
      The Earth’s energy imbalance is the net radiative flux at the top-of-atmosphere. Climate model simulations suggest that the observed positive imbalance trend in the previous two decades is inconsistent with internal ...
    • Satellite-based analysis of top of atmosphere shortwave radiative forcing trend induced by biomass burning aerosols over South-Eastern Atlantic 

      Jouan, Caroline; Myhre, Gunnar (Peer reviewed; Journal article, 2024)
      This study investigates long-term changes in the shortwave direct aerosol radiative effect (DARE) at the top of the atmosphere (TOA) induced by biomass burning aerosol (BBA) transported from southern Africa to the south-eastern ...
    • Strong contribution from sensible heat to global precipitation increase in climate models is not supported by observational based data 

      Myhre, Gunnar; Jouan, Caroline; Stjern, Camilla Weum; Hodnebrog, Øivind (Peer reviewed; Journal article, 2024)
      It has previously been shown that trends in sensible heat from climate models have had a substantial contribution to global precipitation changes. We illustrate that this is the case also in the most recent Coupled Model ...
    • The Time Scales of Climate Responses to Carbon Dioxide and Aerosols 

      Stjern, Camilla Weum; Forster, Piers M.; Jia, Hailing; Jouan, Caroline; Kasoar, Matthew R.; Myhre, Gunnar; Oliviè, Dirk Jan Leo; Quaas, Johannes; Samset, Bjørn Hallvard; Sand, Maria; Takemura, Toshihiro; Voulgarakis, Apostolos; Wells, Christopher D. (Peer reviewed; Journal article, 2023)
      The climate system responds to changes in the amount of atmospheric greenhouse gases or aerosols through rapid processes, triggered within hours and days, and through slower processes, where the full response may only be ...
