|Climate change and glaciers|
Detecting and quantifying glacier retreat and advancement, glacier area changes, and glacier lake changes is one of the most important contributions satellite technology can make to further our understanding of climate change. For a large number of glaciers, especially those found in remote places, satellite remote sensing is the only method scientists have to study them.
|Glacier Ice Flow|
Global warming has been shown to affect the ice flow of glaciers. With the use of Earth Observation satellites, scientists are able to study and monitor glaciers, even those that are located in remote areas.
In this case study, you will learn how remote sensing can aid in the monitoring of tropical rainforests, such as the Amazon rainforest. You will see how this forest disappeared over a period of 30 years, and how the rate of deforestation can be measured. You will also learn that, even in deforested areas, the process of vegetation growth still goes on.
