; climateInterpretation_seasonality changed - was originally 6 7
Strong sign-to-noise ratio in the mean divergence-free regional chronology (representing a network of 29 sites in the Mackenzie Delta region) with Expressed Population Signal (EPS) > 0.85 since AD 1400, and EPS > 0.7 back to AD 1245. The chronology shares a moderate to strong positive correlation with local summer temperatures (r = 0.6, p < 0.001) over the calibration period, and moderate to strong correlations with several other reconstructions from surrounding regions spanning the last millenium.
Significant correlation (p<0.001) to local meteo data
