  <Summary>
    <Abstract>Climate variations influenced the agricultural productivity, 
health risk, and conflict level of preindustrial societies. 
Discrimination between environmental and anthropogenic impacts 
on past civilizations, however, remains difficult because of 
the paucity of high-resolution paleoclimatic evidence. 
We present tree ring–based reconstructions of central European 
summer precipitation and temperature variability over the past 
2500 years. Recent warming is unprecedented, but modern 
hydroclimatic variations may have at times been exceeded 
in magnitude and duration. Wet and warm summers occurred 
during periods of Roman and medieval prosperity. Increased 
climate variability from ~250 to 600 C.E. coincided with 
the demise of the western Roman Empire and the turmoil of 
the Migration Period. Such historical data may provide a basis 
for counteracting the recent political and fiscal reluctance 
to mitigate projected climate change. 
 
          STUDY NOTES:   A central European summer temperature proxy was developed based on 1089 stone pine (Pinus cembra) and 457 European larch (Larix decidua) ring width series from high-elevation
       sites in the Austrian Alps and adjacent areas. This composite record includes living trees, historical timber, and subfossil wood, and correlates at 0.72 to 0.92 with interannual to multidecadal
       variations in instrumental June-to-August (JJA) temperature (1864–2003). The new proxy is significantly positive correlated with 20th century JJA temperatures of central Europe and the Mediterranean
       region, and possesses high- to low-frequency agreement with an independent maximum latewood density-based temperature surrogate from the Swiss Alps (r = 0.35 to 0.44; 755 to 2003 C.E.).
