Short summary
To accurately understand past climate change, exact chronologies are fundamental. We dated multiple stalagmites from the Yucatán Peninsula covering the last 2700 years. Because these cave deposits contain high and variable amounts of contaminating elements that distort age models, we developed a multi-method approach to correct the timelines. Our corrected records now provide a reliable foundation for future studies to track ancient droughts, floods, and their links to Maya cultural evolution.
