This document summarizes research on glacier retreat and water resource vulnerability at Volcán Chimborazo in Ecuador. The researcher found that between 1986 and 2010, glaciers at Chimborazo experienced a 35% reduction in surface area. Ongoing research includes continued monitoring of glacier change over time using remote sensing techniques and analysis of errors in measurement methods. The research aims to improve understanding of glacier retreat and its implications for water resources in the region to help assess vulnerability under continued warming.
