Recent warming is unprecedented, but modern \nhydroclimatic variations may have at times been exceeded \nin magnitude and duration. Wet and warm summers occurred \nduring periods of Roman and medieval prosperity. Increased \nclimate variability from ~250 to 600 C.E. coincided with \nthe demise of the western Roman Empire and the turmoil of \nthe Migration Period.
