ABSTRACT
There are many glaciers in the O'Higgins Lake area with perennial snow. It is of great scientific and practical significance to understand glaciers' current situation and changes here. Using Landsat remote sensing images, climate, and glacier inventory data, this paper studies the glacierized and snow-cover area changes in the O'Higgins Lake area from 2000 to 2020. The results show that the glacierized and snow-cover area in the O'Higgins Lake area has an obvious downward trend in 2020. Compared with July 7, 2000, the area decreased by 9.34% on July 14, 2020. This downward trend is a climate response to the average temperature rise rate of 0.0724 °C / A in the O'Higgins Lake area from 2000 to 2020.
