Study objectives:<\/span><\/strong>\u00a0The widely discussed warming of the arctic during the last decades is comparable to the warming period that commenced in the late 1910s and lasted until the early 1940s (Fig.: I_Arctic_1918-1940). The most significant difference between these two periods is the sea ice cover. In stark contrast to the annual sea ice losses during the last two decades, the seasonal sea ice cover during the former period from 1920-1940 remained on the whole unaltered. Although understanding the earlier arctic warming may provide valuable clues on what has caused the current situation in the Arctic, recent research papers offer little hindsight in this respect. For example, Lennart Bengtsson et al. regard this event as \u201cone of the most puzzling climate anomalies of the 20th\u00a0 century<\/em>\u201d (\u201cThe Early Twentieth-Century Warming in the Arctic\u2014A Possible Mechanism\u201d, Journal of Climate, October 2004, page 4045-4057), and assume: \u201cthat natural variability is the most likely cause\u201d; ditto:\u00a0James E. Overland<\/strong>\u00a0<\/strong>and\u00a0\u00a0Ola M. Johannessen, et al. (Reference details: Chapter B at: http:\/\/www.arctic-warming.com).<\/strong>\u00a0<\/strong>As\u00a0 the notion \u201cnatural variability\u201d is of little help for understanding the current situation in the Arctic, the paper aims at identifying the main parameters of the sudden warming in the first half of the 20th century, respectively to answer the question:\u00a0Why are the maximum climate fluctuations confined to the Atlantic sector of the Arctic<\/em>?\u201d\u00a0<\/em>V.F.
