Permafrost consists of soil, rock, or sediment that remains frozen for a minimum of two consecutive years. This geological formation occurs primarily in polar regions and high-altitude mountainous areas, where temperatures remain consistently below freezing. Permafrost serves as a significant component of Arctic ecosystems and functions as a storage system for carbon and other greenhouse gases.
These frozen layers can reach depths of several hundred meters and contain organic material that has been preserved for thousands of years. Current climate change trends have accelerated permafrost thawing rates across affected regions. Increased global temperatures, resulting from anthropogenic activities including fossil fuel emissions and land-use changes, have elevated Arctic surface temperatures and initiated widespread permafrost degradation.
Permafrost thawing generates consequences that extend beyond immediate geographic boundaries. The decomposition of previously frozen organic matter releases substantial quantities of carbon dioxide and methane into the atmosphere, contributing to enhanced greenhouse gas concentrations and accelerated climate warming. The structural transformation of thawing permafrost fundamentally alters ground stability, resulting in surface subsidence, erosion, and terrain deformation.
These changes compromise existing infrastructure including transportation networks, residential and commercial buildings, and energy distribution systems, creating risks of structural damage and operational failure in affected areas.
