Abstract

A diatom-based calibration model for predicting summer temperatures was developed using climatically sensitive subarctic lakes in northern Fennoscandia. The model was applied to a sediment core from a treeline lake to infer trends in Holocene climate. The record exhibits long-term variations, as well a series of shorter-term fluctuations on a time scale of centuries. The similarity of the observed shifts with the pacings of climate events from marine and ice-core records represents evidence for coupled ocean-atmosphere forcing of the regional climate
