- Tree-ring widths from 880 living, dry dead, and subfossil northern Swedish pines (Pinus sylvestris L.) have been assembled into a continuous and precisely dated chronology (the Tornetrask chronology) covering the period 5407 BC to AD 1997. Biological trends in the data were removed with autoregressive standardization (ARS) to emphasize year-to-year variability, and with regional curve standardization (RCS) to emphasize variability on timescales from decades to centuries. The strong association with summer mean temperature (June-August) has enabled the production of a temperature reconstruction for the last 7400 years, providing information on natural summer-temperature variability on timescales from years to centuries. Numerous cold episodes, comparable in severity and duration to the severe summers of the seventeenth century, are shown throughout the last seven millennia. Particularly severe conditions suggested between 600 and 1 BC correspond to a known period of glacier expansion, The relatively warm conditions of the late twentieth century do not exceed those reconstructed for several earlier time intervals, although replication is relatively poor and confidence in the reconstructions is correspondingly reduced in the pre-Christian period, particularly around 3000, 1600 and 330 BC. Despite the use of the RCS approach in chronology construction, the 7400-year chronology does not express the full range of millennial-timescale temperature change in northern Sweden.

Diverse construction types and local timber sources characterize early medieval church roofs in southwestern Sweden

Tidskriftsartikel (refereegranskat)abstract
- A vast number of early medieval roof structures are still preserved in Swedish churches, yet countrywide surveys and detailed dendrochronological investigations, in tandem with building archaeology, are largely lacking. Here, we present new findings from four parish churches (Forsby, Forshem, Gökhem and Marka) in Västergötland, southwestern Sweden. The roof constructions, made from local oak and pine trees, were dated to the period between AD 1131 and 1157, making these some of the oldest preserved roof structures in Sweden and Europe. With the development of new regional pine and oak tree-ring chronologies covering the 10th to 13th centuries, we open up the discussion about medieval timber technology, wood utilization and the potential for future tree-ring based paleo-environmental exploration.
