**A Glaciologist Measures a Glacier’s Surface Area Using Satellite Images. The Glacier Covers 120 Square Kilometers Initially. Due to Climate Change, It Shrinks by 8% Each Year. What Will Its Surface Area Be After 3 Years?** Recent reports highlight shrinking ice masses as a stark indicator of climate change, with glaciologists relying on satellite technology to track these transformations with precision. In this frame, a glaciologist measures a glacier’s surface area using satellite images. The glacier begins at 120 square kilometers, now visibly reduced each year due to rising temperatures and shifting climate patterns. This isn’t just an isolated measurement—it’s part of a broader trend globally, where glaciers serve as vital barometers of Earth’s changing climate. The data tells a clear story: sustained shrinkage matters. Why is this moment significant for the U.S. audience? Climate-related shifts are no longer far-off projections—they shape ecosystems, water supplies, and disaster preparedness. As communities observe glaciers retreat, the insights from glaciologists become critical to understanding regional impacts, from water resource management to long-term environmental policy. The use of satellite imagery not only enhances accuracy but also brings real-time evidence into public view, deepening awareness of climate urgency without speculation or exaggeration. Measuring a glacier’s surface area with satellite images involves advanced remote sensing techniques. By capturing high-resolution images across multiple time points, glaciologists analyze changes in land coverage, translating pixel data into precise surface area metrics. This method avoids outdated gathering techniques, delivering reliable annual assessments essential for modeling glacier behavior over decades. For a glacier currently spanning 120 square kilometers, consistent satellite monitoring reveals a steady 8% annual reduction—a trend supported by scientific and observational data.
