Six Degrees

Summary

A wide ranging account of climate change for general readers, organized around what happens to Earth at each successive degree of warming above preindustrial levels. Drawing on thousands of peer reviewed studies, Lynas constructs a vivid, evidence based scenario for each threshold, from melting Arctic ice at one degree to civilizational collapse at six. The structure makes abstract climate projections tangible, transforming dense science into a sequence of concrete, escalating consequences.
