A 200‐m ice core obtained in 1976 on the Lomonosov Plateau in Spitsbergen is compared with isotope profiles obtained at the Camp Century and Crete stations on Greenland and on Devon Island as well as temperature curves for Iceland and England. All of them clearly show a cool 19th century and a warm 16th century. The Spitsbergen data, both for 1730–1890 and for the 13th‐15th centuries, come closest to those for the two Greenland stations. The Spitsbergen hole also suggests warm conditions for the 12th century, similar to the march of temperature in Iceland, although the warm period in England was 100 to 150 years longer.
