Article: "Low-Frequency Signals in Long Tree-Ring Chronologies for Reconstructing Past Temperature Variability."

Tree-ring chronologies can preserve coherent large-scale multicentennial temperature trends.
These chronologies support large-scale occurrence of Medieval Warming Period over the Northern Hemisphere extratropics centered at 1000 AD.
Strong evidence for below-average temperature over much of 1200-1850 AD.
The 1000- to 2000-year climate rhythm in the North Atlantic ocean may be cause of multicentennial variations.
