A glaciologist uses remote sensing to measure a glaciers thickness. If the thickness decreases from 500 meters to 450 meters over 5 years, what is the average annual rate of thickness loss?

**A glaciologist uses remote sensing to measure a glacier’s thickness. If that thickness decreases from 500 meters to 450 meters over 5 years, what is the average annual rate of thickness loss?** In an era of accelerating climate change, subtle shifts in Earth’s frozen landscapes reveal profound environmental stories. The data now widely acknowledged shows glaciers across the U.S. and beyond are thinning at measurable rates—driven by warming temperatures and shifting weather patterns. When a glacier’s thickness drops from 500 meters to 450 meters over five years, understanding the pace of loss becomes vital to interpreting long-term climate impacts. This article explores how modern glaciologists use advanced remote sensing technology to track these changes—and what the numbers actually mean. --- ### Why Remote Sensing Has Become Key to Tracking Glacier Health
