Stratospheric volcanic eruptions have had significant impacts on the radiation budget, atmospheric and surface temperatures, precipitation and regional weather patterns, resulting in global climatic changes. The changes associated with such eruptions most commonly result in cooling during several years after events.

This study aimed to reveal eco-physiological response of larch trees from northeastern Yakutia (YAK), eastern Taimyr (TAY) and Altai (ALT) regions to climatic anomalies after major volcanic eruptions 535, 540, 1257, 1641 and 1991 using new multiple tree-ring parameters: tree-ring width (TRW), maximum latewood density (MXD), cell wall thicknesses (CWT), d¹³C, d¹⁸O in tree-ring cellulose.

This investigation showed that TRW, CWT, MXD and d¹⁸O chronologies recorded temperature signal, while information about precipitation and vapor pressure deficit was captured by d¹³C chronologies. Sunshine duration was well recorded in d¹⁸O from YAK and ALT. Tree-ring parameters recorded cold, wet and cloudy summer anomalies during VI and XIII centuries. However, summer anomalies after Tambora and Pinatubo eruptions were not revealed in Siberian tree-ring parameters. This proof of our concept that likely not all volcanic eruptions induced reduction in temperature, precipitation and solar radiation globally over second part of the past millennium.
