Ring-width variations in stone pine near upper treeline in the Alps show a high negative correlation with the percentage of advancing glaciers in Austria and Switzerland. The relationship is due to the similarity of climatic models for tree growth and the glacial mass budget. Tree-ring fluctuations during the period 1800-1889, prior to the compilation of glacial statistics show good agreement with historical glacial advances and periods of low summer temperatures, especially around 1820-1855. Tree-ring studies could assist in reconstructing the glacial and climatic history of the Alps, possibly for a period of 1,000 years or more.
