This introductory chapter examines the politics of geoengineering, analyzing how deliberate large-scale climate interventions have evolved from theoretical concepts to contested policy realities. Through a multidisciplinary framework integrating political science, economics, and innovation science, we trace geoengineering’s trajectory from early 20th-century proposals to contemporary governance challenges. Our analysis identifies six critical analytical dimensions—environmental, political, economic, legal, societal, and justice-based—that shape geoengineering development. Moreover, it reveals an increasingly polarized landscape where technological capabilities advance faster than governance frameworks, creating a “risk versus risk” scenario between climate inaction and potentially disruptive interventions. Drawing on national policy developments, international regulatory efforts, and emerging funding patterns, we demonstrate that geoengineering now requires urgent governance attention. The chapter concludes by outlining this volume's comprehensive examination of the social, political, and ethical dimensions of climate intervention.

摘要

This introductory chapter examines the politics of geoengineering, analyzing how deliberate large-scale climate interventions have evolved from theoretical concepts to contested policy realities. Through a multidisciplinary framework integrating political science, economics, and innovation science, we trace geoengineering’s trajectory from early 20th-century proposals to contemporary governance challenges. Our analysis identifies six critical analytical dimensions—environmental, political, economic, legal, societal, and justice-based—that shape geoengineering development. Moreover, it reveals an increasingly polarized landscape where technological capabilities advance faster than governance frameworks, creating a “risk versus risk” scenario between climate inaction and potentially disruptive interventions. Drawing on national policy developments, international regulatory efforts, and emerging funding patterns, we demonstrate that geoengineering now requires urgent governance attention. The chapter concludes by outlining this volume's comprehensive examination of the social, political, and ethical dimensions of climate intervention.
