**A glacier loses 12 meters of thickness in the first year, and the annual loss increases by 15% each year. What is the total thickness lost over the first 3 years?** Why are increasing glacier losses becoming a quietly urgent topic in today’s changing climate? The fact that one glacier shed 12 meters of ice thickness in its first year—and continued to lose more each year—draws growing attention. This steady decline isn’t just a local concern; it reflects a broader pattern of accelerating glacial retreat driven by rising global temperatures. As measurements show, that initial 12-meter loss each year triggers a growing melt over time, with each subsequent year losing more than the last. This pattern offers clear insight into how even moderate annual losses compound into significant long-term change. Understanding this trend helps readers grasp the rhythm of climate impact affecting water resources, sea levels, and ecosystems across the United States and beyond. Guided by practical curiosity, the question “What is the total ice loss over the first three years?” naturally leads to a calculation rooted in incremental growth. Starting with 12 meters in Year 1, a 15% increase each year means the loss climbs steadily. In Year 2, the ice thins by 12 × 1.15 = 13.8 meters. By Year 3, losses rise to 13.8 × 1.15 = 15.87 meters. Adding these together reveals the true cumulative impact invisible at first glance. The full breakdown illustrates how small increments made over time add up to major change—underscoring the importance of long-term environmental monitoring. This growth pattern mirrors climate data revealing accelerating glacial retreat worldwide. For U.S. audiences, particularly those in climate-vulnerable regions or policy-focused communities, understanding these numbers transforms abstract climate change into tangible metrics. The total thickness lost over just three years totals 12 + 13.8 + 15.87 = 41.67 meters—underscoring how even gradual changes can reshape landscapes and water systems.
