(Peer reviewed; Journal article, 2019-07-25)
      The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time that Earth's atmospheric CO2 concentrations exceeded 1000 ppm. Global mean temperatures were also substantially warmer than those ...

    • Environmental responses to the 9.7 and 8.2 cold events at two ecotonal sites in the Dovre mountains, mid-Norway 

      Paus, Aage; Haflidason, Haflidi; Routh, Joyanto; Naafs, B. David A.; Thoen, Mari Woxen (Peer reviewed; Journal article, 2019)
      We found strong signals of two cooling events around 9700 and 8200 cal yrs. BP in lakes Store Finnsjøen and Flåfattjønna at Dovre, mid-Norway. Analyses included pollen in both lakes, and C/N-ratio, biomarkers (e.g. alkanes ...

    • Northern hemisphere glaciation during the globally warm early late Pliocene
