摘要

Glaciers and ice sheets, vital components of the Earth’s climate system and crucial freshwater sources, are rapidly retreating under the influence of climate change. This study reviews the use of remote sensing technologies in monitoring these changes, highlighting tools like Synthetic Aperture Radar (SAR) and satellite imagery from Landsat and MODIS. These technologies provide detailed measurements of ice dynamics, revealing substantial regional variability in ice loss, particularly in the Arctic and Antarctic. This study synthesizes recent data on glacial retreat, examines the impact of temperature increases and precipitation changes on ice melt, and assesses the consequences for freshwater availability in glacier-dependent regions. Case studies demonstrate the application of remote sensing in observing these phenomena, emphasizing the need for advancements in technology and international cooperation in research. The study concludes with a discussion on policy implications and conservation measures necessary to address the environmental challenges posed by glacial decline, advocating for strategic international agreements and local policies to mitigate the effects of global warming on glaciers.
