Dendrochronology: Irish peat-bog oaks and Fennoscandian pines indicate a cold interval in 536–545 CE. Tree-ring growth dropped sharply in 536 across several records. The interval may have been the coldest decade of the past 2,000 years. Mike Baillie of Queen’s University Belfast presented the evidence in Astronomy & Geophysics in February 2004.
Tree rings suggest 536–545 may have been the coldest decade in 2,000 years
Key facts
- The analysis was published in Astronomy & Geophysics in February 2004, not 1999.
- The researcher is Mike Baillie of Queen’s University Belfast, not “Bailey.”
- Irish peat-bog oak records show exceptionally poor growth in 536 CE; the cold interval discussed extends through 545.
- The interval 536–545 spans ten calendar years inclusive, not approximately eight years.
- The sharp multi-chronology growth decline is placed at 536, not around 540.
- The evidence suggests that 536–545 may have been the coldest decade of the past 2,000 years; it does not establish the superlative as certain.
