Permafrost Secrets explores the hidden world of thawing Arctic permafrost and its global implications. It reveals how this once-frozen ground contains a wealth of ancient organic matter, potentially viable microorganisms, and vast stores of greenhouse gases. As the Arctic warms at twice the global average, this thaw accelerates climate change through the release of methane and carbon dioxide, creating a dangerous feedback loop.

The book examines permafrost from multiple angles, detailing its geological history, biological contents, and the practical risks of its degradation. One alarming insight is the potential re-emergence of ancient viruses, posing new threats to global health. Another is the increasing infrastructure damage in Arctic regions, disrupting communities and economies.

Adopting an evidence-based approach, Permafrost Secrets synthesizes findings from geology, microbiology, and climatology to present a comprehensive picture. Beginning with a foundational understanding of permafrost, the book progresses through its composition, climate impacts, and associated risks, culminating in a call to action for scientists and policymakers.
