Geologists studying ancient fossil corals in the Cook Islands have uncovered vital data that could completely reshape our understanding of global sea level rise. By analyzing the structural patterns and ages of these prehistoric marine structures, researchers from Columbia University are mapping exactly how ocean heights responded during past warming periods. Because these fossils act as flawless historical tide gauges, they give scientists a precise look into long-term climate behavior. The findings provide crucial data for refining current computer models, helping coastal cities better prepare for future climate impacts.
