Ancient tree rings are a hidden archive of droughts, solar storms and human history, and scientists say some can date events to the exact year

Tree rings serve as a natural archive detailing past environmental conditions and events. Scientists use these annual growth rings to reconstruct climate and date historical occurrences precisely. Dendrochronologists match overlapping patterns to build chronologies stretching back thousands of years. These records reveal past droughts, volcanic eruptions, and powerful solar storms like the Miyake Event. This research helps understand climate change and improve future predictions.
