A joint research project of the Chronology Laboratory of the Finnish Museum of Natural History and Natural Resources Institute Finland (Luke) suggests that the years 536 and 541–544 CE were very difficult Samuli Helama, Finnish Forest Research Institute, Rovaniemi Unit, PO Box 16, FI-96301 Rovaniemi, Finland. E-mail: samuli.helama@metla.fi Abstract Geochronological data of the conifer tree rings in a region sensitive to climatic effects of explosive eruptions were analysed for sudden growth reductions in Samuli Helama. Annual temperatures are generally rising in the northern hemisphere, but the trend is not that clear in Finland. First, there was an ascending of temperatures up to the mid-1930s, Samuli Helaman monitasoinen runoteos Kuva kuvas vie suomalaista runoutta takaisin sinne mistä se on lähtöisin, tarinallisuuteen.

Plant phenological data from northern Finland, compiled from several sources, were examined as potential biometeorological indicators of climate change since the 18th century. A common feature of individual series was their sporadic nature. In addition to waning enthusiasm, wartime hardships and crop failures had caused gaps in recording observations during the 18th and 19th centuries. The
