Beneath vast stretches of the Arctic and high mountain regions lies permafrost, ground that has remained frozen for thousands of years and is now beginning to thaw.Beneath vast stretches of the Arctic and high mountain regions lies permafrost, ground that has remained frozen for thousands of years and is now beginning to thaw. This book examines what that shift means for the planet and for the people who depend on stable ground and predictable climate patterns. Generated by an AI system, this book draws together current scientific understanding to explain how permafrost forms, why it is thawing, and what consequences follow. You will learn about the release of greenhouse gases from ancient soils, the effects on infrastructure and ecosystems, and the challenges researchers face in measuring and predicting these changes. Written as a clear introduction to the subject, it offers you a factual foundation for understanding one of the more overlooked aspects of a changing climate.Beneath vast stretches of the Arctic and high mountain regions lies permafrost, ground that has remained frozen for thousands of years and is now beginning to thaw.
