Definition

Permafrost is ground that remains frozen for at least two consecutive years. It's typically found in colder regions, like Alaska, Siberia, and Canada. Permafrost contains frozen water, soil, and organic matter. As the climate warms, permafrost thaws, releasing greenhouse gases. This thawing can lead to unstable ground and infrastructure damage. It poses a significant threat to the environment.

Etymology

The word "permafrost" is a combination of "permanent" and "frost." It was coined in the early 20th century to describe permanently frozen ground. The term reflects the long-lasting nature of the frozen state. The study of permafrost is known as permafrost science. Understanding permafrost is crucial for climate change research.
