      abstract     = {We present the first European network of tree ring delta
                      C-13 and delta O-18, containing 23 sites from Finland to
                      Morocco. Common climate signals are found over broad
                      climatic-ecological ranges. In temperate regions we find
                      positive correlations with summer maximum temperatures and
                      negative correlations with summer precipitation and Palmer
                      Drought Severity Indices (PDSI) with no obvious
                      speciesspecific differences. Regional delta C-13 and delta
                      O-18 chronologies share high common variance in year-to-year
                      variations. Long-term variations, however, exhibit
                      differences that may reflect spatial variability in
                      environmental forcings, age trends and/or plant
                      physiological responses to increasing atmospheric CO2
                      concentration. Rotated principal component analysis (RPCA)
                      and climate field correlations enable the identification of
                      four sub-regions in the delta O-18 network - northern and
                      eastern Central Europe, Scandinavia and the western
                      Mediterranean. Regional patterns in the delta C-13 network
                      are less clear and are timescale dependent. Our results
                      indicate that future reconstruction efforts should
                      concentrate on delta O-18 data in the identified European
                      regions.},
