European tree-ring sequences

European tree-ring sequences are records of annual growth patterns in trees across Europe, created by analyzing the width and characteristics of each year's growth ring. These patterns reflect environmental conditions such as climate, temperature, and rainfall over time. By studying many trees, scientists can build a continuous chronological sequence that helps date archaeological sites, understand historical climate changes, and reconstruct past environments. Essentially, these sequences serve as natural, long-term climate archives that reveal how Europe's climate has varied over centuries or even millennia.
