Glacier and climatic fluctuations inferred from tree‐growth variations over the last 250 years, central southern Norway
A Pinus sylvestris (Scots pine) tree‐growth series from near the tree‐line in upper Gud‐ brandsdalen, southern Norway (Slistad 1957) is analysed, and possible relationships to glacier and climatic fluctuations are explored. The series is smoothed by harmonic analysis, and calibrated using a variety...
