Abstract Five proxy temperature time series based on tree-rings and varves from the middle and high latitudes (φ >50°) of North America were analyzed. They cover the last 3–5 centuries. It was shown that the reconstructions from Canadian Rockies (52.15°N, 117.15°W) and northeast Alaska (68.8°N, 142.3°W) correlate appreciably with Wolf number and 10Be concentration in Greenland ice over long (T >13years) time scales. Correlations are weaker for the reconstruction from northwestern Canada (68.25°N, 133.33°W). Baffin Island (66.6°N, 61.3°W) and the Gulf of Alaska (49–62°N, 123–145°W) show no correlations with records of solar activity. Thus, these results indicate that solar-climatic effects have an apparent regional distribution. Possible causes of this regionality are discussed.
