Geocryology is the study of frozen ground and the processes that occur in cold regions of the Earth. It focuses on understanding the properties and behavior of permafrost, glaciers, and other forms of ice, which play a crucial role in the Earth's climate and ecosystems. Geocryologists examine how these frozen materials interact with the environment, including their impact on hydrology and vegetation. This field is essential for predicting the effects of climate change, as rising temperatures can lead to thawing permafrost, which releases greenhouse gases like methane. By studying geocryology, scientists can better understand the implications of these changes for both local and global environments.
