The Finnish "Supra-Long" Chronology #1

Jan 5, 2009 – 10:21 AM

Over the past 30 years, Finnish dendrochronologists have developed a “supra-long” tree ring chronology now stretching back (Helama et al 2008) to 7600BP, well into the Holocene Optimum. Earlier versions of this chronology have been reported in many articles (e.g. Helama et al 2002, Eronen et al 2002 and references back into the 1990s plus […]

This is consistent with the more northerly distribution of oak in medieval Finland reported in Hulden [2001] discussed here and adds to the growing inventory of articles both demonstrating higher medieval treelines and using […]

Medieval Treelines #1

Feb 12, 2005 – 5:51 PM

Larry Huldén of the Finnish Museum of Natural Science sent me a nice note, mentioning: I have met Phil Jones in Helsinki during a Climate meeting. My wife had a paper on mediaeval warm period in Finland in which she showed that oak (Quercus robur) forests occurred some 150 km north of the present time […]
