About this audiobook

Beneath a quarter of the Northern Hemisphere's land lies ground that has stayed frozen for two years, or two centuries, or since before human history began. Permafrost is the quiet half of the cryosphere: invisible from the air, measured in boreholes, and taken for granted by every road, pipeline, and town built above it. This book explains what that frozen ground is, why it is thawing, and what its thaw means for the climate, the Arctic's people, and the world. The early chapters build the picture: how permafrost is defined and mapped into continuous, discontinuous, and sporadic zones; how buried ice and frost heave build pingos, ice wedges, and patterned ground; how the frozen carbon archive accumulated over tens of thousands of years; and how a century of research, from the Great Northern Expedition to the International Permafrost Association, uncovered it.
