• Arctic hydroclimate variability during the last 2000 years: Current understanding and research challenges 

      Linderholm, Hans W.; Nicolle, Marie; Francus, Pierre; Gajewski, Konrad; Helama, Samuli; Korhola, Atte; Solomina, Olga; Yu, Zicheng; Zhang, Peng; D'Andrea, William J.; Debret, Maxime; Divine, Dmitry V; Gunnarson, Björn E.; Loader, Neil J.; Massei, Nicolas; Seftigen, Kristina; Thomas, Elizabeth K.; Werner, Johannes; Andersson, Sofia; Berntsson, Annika; Luoto, Tomi P.; Nevalainen, Liisa; Saarni, Saija; Väliranta, Minna (Peer reviewed; Journal article, 2018-04-10)
      Reanalysis data show an increasing trend in Arctic precipitation over the 20th century, but changes are not homogenous across seasons or space. The observed hydroclimate changes are expected to continue and possibly ...
    • Climate variability in the subarctic area for the last 2 millennia 

      Nicolle, Marie; Debret, Maxime; Massei, Nicolas; Colin, Christophe; de Vernal, Anne; Divine, Dmitry V; Werner, Johannes; Hormes, Anne; Korhola, Atte; Linderholm, Hans W. (Peer reviewed; Journal article, 2018-01-25)
      To put recent climate change in perspective, it is necessary to extend the instrumental climate records with proxy data from paleoclimate archives. Arctic climate variability for the last 2 millennia has been investigated ...
    • Early Holocene Temperature Oscillations Exceed Amplitude of Observed and Projected Warming in Svalbard Lakes 

      Bilt, Willem van der; D'Andrea, William J.; Werner, Johannes; Bakke, Jostein (Journal article; Peer reviewed, 2019)
      Arctic climate is uniquely sensitive to ongoing warming. The feedbacks that drive this amplified response remain insufficiently quantified and misrepresented in model scenarios of future warming. Comparison with paleotemperature ...
    • European summer temperatures since Roman times 

      Luterbacher, Jürg; Werner, Johannes; Smerdon, Jason E.; Fernández-Donado, Laura; González-Rouco, Fidel J.; Barriopedro, David E.; Ljungqvist, Fredrik Carpentier; Büntgen, Ulf; Zorita, Eduardo Valera; Wagner, Sebastian; Esper, Jan; McCarroll, Danny; Toreti, Andrea; Frank, David C.; Jungclaus, Jojann H.; Barriendos, Mariano; Bertolin, Chiara; Bothe, Oliver; Brázdil, Rudolf; Camuffo, Dario; Dobrovolný, Petr; Gagen, Mary H.; Garcia-Bustamante, Elena; Ge, Q.; Guiot, Joël; Gómez-Navarro, Juan José; Hao, Z.; Hegerl, Gabi C.; Holmgren, Karin; Klimenko, Vladimir V.; Martin-Chivelet, Javier; Pfister, Christian; Roberts, Neil; Schindler, Anne; Schurer, Andrew P.; Solomina, Olga N.; Von Gunten, Lucien; Wahl, Eugene R.; Wanner, Heinz; Wetter, Oliver; Xoplaki, Elena; Yuan, Naiming; Zanchettin, Davide; Zhang, Huan; Zerefos, Christos S. (Journal article; Peer reviewed, 2016)
      The spatial context is critical when assessing present-day climate anomalies, attributing them to potential forcings and making statements regarding their frequency and severity in a long-term perspective. Recent international ...
    • Palaeo-productivity record from Norwegian Sea enables North Atlantic Oscillation (NAO) reconstruction for the last 8000 years 

      Becker, Lukas; Sejrup, Hans Petter; Hjelstuen, Berit Oline Blihovde; Haflidason, Haflidi; Kjennbakken, Heidi; Werner, Johannes (Journal article; Peer reviewed, 2020)
      The North Atlantic Oscillation is the dominant atmospheric driver of North Atlantic climate variability with phases corresponding to droughts and cold spells in Europe. Here, we exploit a suggested anti-correlation of North ...
    • Processes Prior and during the Early 18th Century Irish Famines—Weather Extremes and Migration 

      Engler, Steven; Werner, Johannes (Peer reviewed; Journal article, 2015-12-10)
      This paper advances the current debates on famine and famine history, with a focus on the first half of the 18th century in Ireland. Ireland was often hit by severe famines and two of them, specifically the famines of ...
    • Spatio-temporal variability of Arctic summer temperatures over the past 2 millennia 

      Werner, Johannes; Divine, Dmitry V; Ljungqvist, Fredrik Charpentier; Nilsen, Tine; Francus, Pierre (Peer reviewed; Journal article, 2018-04-24)
      In this article, the first spatially resolved and millennium-length summer (June–August) temperature reconstruction over the Arctic and sub-Arctic domain (north of 60°N) is presented. It is based on a set of 44 annually ...
