[Extreme Climatic Events in the Altai Republic According to Dendrochronological Data]

Area of Science:

• Paleoclimatology
• Dendrochronology
• Volcanology

Context:

• Investigating extreme climatic events using tree-ring analysis of Siberian larch (Larix sibirica).
• Examining anatomical damage and missing rings in trees from the Altai Republic's upper forest boundary.
• Analyzing spatial distribution of dated events across seven study plots.

Purpose:

• To date extreme climatic events by analyzing anatomical damage and missing tree rings in Siberian larch.
• To differentiate extreme events on interregional, regional, and local scales based on spatial distribution.
• To correlate identified extreme events with historical records of volcanic eruptions and climate anomalies.

Summary:

• Dating of extreme climatic events was performed using anatomical damage and missing tree rings in Siberian larch from the Altai Republic.
• Analysis identified interregional (e.g., 1700, 1884), regional (e.g., 1724, 1961), and local (e.g., 1702, 2009) scale events.
• Interregional events align with major volcanic eruptions (e.g., Tambora, Krakatau) and documented climate extremes.

Impact:

• Provides a high-resolution paleoclimate record for the Altai region.
• Corroborates historical accounts of climate-driven disasters and volcanic impacts.
• Enhances understanding of the scale and timing of past extreme climatic events and their drivers.
