A glacier in Greenland retreats at a rate of 1.2 meters per year. If it was 1,800 meters wide in 2000, how wide will it be in 2030 assuming linear retreat?

Title: How Earth’s Glaciers Are Retreating: A Greenland Glacier’s Shrinking Trend In recent decades, Greenland’s glaciers have become powerful symbols of climate change, with many retreating at alarming rates. A key metric helps highlight this shift: if a glacier was 1,800 meters wide in 2000 and is now retreating at 1.2 meters per year, how much narrower will it be by 2030 under a linear model? Understanding this helps scientists and communities grasp the pace of environmental change. ### The Linear Retreat Calculation From 2000 to 2030, 30 years pass—offer time for consistent retreat progress. With a retreat rate of 1.2 meters annually, the total reduction is calculated as:
