Temperature Reconstruction and Comparison with Other Regional Records

Three proxy climate records covering the last 1500 – 2000 years from northern Fennoscandia. (A) δ18O from calcareous lacustrine sediments from Abisko, Sweden (Rosqvist et al. 2007). (B) Pollen-inferred mean July temperature deviations from 11 lakes (this paper). (C) Tree-ring-inferred summer (April-August) temperature from the Torneträsk region, Sweden (Grudd 2008). The gray zone highlights the cold interval at 1200-1900 AD (‘Little Ice Age’). Smoothed curves are based on a LOESS smoother with span = 0.1
