  • Climate and societal impacts in Scandinavia following the 536 and 540 CE volcanic double event 
    Van Dijk, Evelien; Gundersen, Ingar Mørkestøl; de Bode, Anna; Høeg, Helge Irgens; Loftsgarden, Kjetil; Iversen, Frode; Timmreck, Claudia; Jungclaus, Johann; Krüger, Kirstin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    In the Northern Hemisphere, the mid-6th century was one of the coldest periods of the last 2000 years, as indicated by both proxy records and Earth System Model (ESM) simulations. This cold period was initiated by volcanic ...
  • Climatic and societal impacts in Scandinavia following the 536 and 540 CE volcanic double event 
    Van Dijk, Evelien; Mørkestøl Gundersen, Ingar; de Bode, Anna; Høeg, Helge; Loftsgarden, Kjetil; Iversen, Frode; Timmreck, Claudia; Jungclaus, Johann; Krüger, Kirstin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    In the Northern Hemisphere, the mid-6th century was one of the coldest periods of the last 2000 years, which was initiated by volcanic eruptions in 536 and 540 CE. Here, we study the effect of this volcanic double event ...
  • On the Additivity of Climate Responses to the Volcanic and Solar Forcing in the Early 19th Century 
    Fang, Shih-Wei; Timmreck, Claudia; Jungclaus, Johann; Krüger, Kirstin; Schmidt, Hauke (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The early 19th century was the coldest period over the past 500 years, when strong tropical volcanic events and a solar minimum coincided. The 1809 unidentified eruption and the 1815 Tambora eruption happened consecutively ...
  • Was there a volcanic-induced long-lasting cooling over the Northern Hemisphere in the mid-6th–7th century? 
    Van Dijk, Evelien; Jungclaus, Johann; Stephan, Lorenz; Timmreck, Claudia; Krüger, Kirstin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract. The climate of the Northern Hemisphere (NH) in the mid-6th century was one of the coldest during the last 2 millennia based on multiple paleo-proxies. While the onset of this cold period can be clearly connected ...
