(Journal article; Peer reviewed, 2019)The VAMPERS (Vrije Universiteit Amsterdam Permafrost Snow Model) has been coupled within iLOVECLIM, an earth system model. This advancement allows the thermal coupling between permafrost and climate to be examined from a ... -
Drivers of soil temperature variation in alpine lichen heaths and shrub vegetation during the summer
Aartsma, Peter; Odland, Arvid; Reinhardt, Stefanie; Renssen, Hans (Peer reviewed; Journal article, 2023)Lichen heaths are decreasing in abundance in alpine and Arctic areas because of an increased competition with shrubs. This shift in vegetation might have important consequences for the soil temperature. The aim of this ... -
The impact of volcanism on Scandinavian climate and human societies during the Holocene: Insights into the Fimbulwinter eruptions (536/540 AD)
Arthur, Frank; Hatlestad, Kailin; Lindholm, Karl-Johan; Loftsgarden, Kjetil; Löwenborg, Daniel; Solheim, Steinar; Roche, Didier M.; Renssen, Hans (Peer reviewed; Journal article, 2024)Recent paleoclimatic research has revealed that volcanic events around 536–540 AD caused severe, short-term global cooling. For this same period, archeological research from various regions evidences significant cultural ... -
Improving biome and climate modelling for a set of past climate conditions: evaluating bias correction using the CDF-t approach
Zapolska, Anhelina; Vrac, Mathieu; Quiquet, Aurélien; Extier, Thomas; Arthur, Frank; Renssen, Hans; Roche, Didier M. (Journal article, 2023)Climate model simulations are inherently biased. It is a notably difficult problem when dealing with climate impact assessments and model-data integration. This is especially true when looking at derived quantities such ... -
Microclimatic comparison of lichen heaths and shrubs: Shrubification generates atmospheric heating but subsurface cooling during the growing season
Aartsma, Peter; Asplund, Johan; Odland, Arvid; Reinhardt, Stefanie; Renssen, Hans (Peer reviewed; Journal article, 2021)Lichen heaths are declining in abundance in alpine and Arctic areas partly due to an increasing competition with shrubs. This shift in vegetation types might have important consequences for the microclimate and climate on ... -

Scussolini, Paolo; Dullaart, Job; Muis, Sanne; Rovere, Alessio; Bakker, Pepijn; Coumou, Dim; Renssen, Hans; Ward, Philip J.; Aerts, Jeroen C. J. H. (Peer reviewed; Journal article, 2023)The Last Interglacial (LIG; ca. 125 ka) is a period of interest for climate research as it is the most recent period of the Earth's history when the boreal climate was warmer than at present. Previous research, based on ... -
