Permafrost

Permafrost is ground that remains frozen for at least two consecutive years, commonly found in Arctic, sub-Arctic and high mountain regions. It contains frozen soil, rock and organic material, including large amounts of stored carbon accumulated over long periods. Thawing permafrost can alter landscapes, damage infrastructure and release greenhouse gases such as carbon dioxide and methane, making it an important factor in climate change research.
