Tree-ring based reconstruction of winter minimum temperatures in the south-western Caspian Sea since 1879

Key Points

• Winter minimum temperatures indicate significant trends since 1879, affecting regional climate studies.
• Temperature changes show variability, with specific increases observed during certain periods.
• Tree-ring based dendrochronology was applied to assess past temperature variations in this region.
• Findings support the need for a deeper understanding of climate effects in global warming scenarios.
