Geoengineering the Climate: A Simple Guide to Big Ideas

"Geoengineering the Climate: A Simple Guide to Big Ideas" offers a clear, accessible exploration of the urgent challenge of climate change and the controversial solutions proposed under the banner of geoengineering. The book begins by unraveling the scientific fundamentals behind climate change—its origins, impacts, and the greenhouse gases driving global warming—before addressing why traditional emissions reductions may no longer be sufficient to safeguard our planet. Readers are introduced to geoengineering, tracing its history, foundational concepts, and the multifaceted motivations behind deliberately intervening in Earth's climate system. Moving beyond the basics, the guide delves into the two primary categories of geoengineering: Solar Radiation Management (SRM) and Carbon Dioxide Removal (CDR). Through balanced, concise explanations, it examines a wide range of techniques, from stratospheric aerosol injection and cloud brightening to direct air capture and ocean-based carbon removal. Each approach is appraised for its scientific promise, potential risks, economic considerations, and ethical dilemmas, empowering readers to grasp both the allure and the controversies that surround these ambitious technologies. Recognizing that geoengineering is as much a social issue as a technical one, the book expands its scope to public attitudes, international governance, and justice concerns. It scrutinizes questions of equity, the potential moral hazards of climate intervention, and the importance of transparency and inclusive dialogue. Closing with future scenarios, responsible innovation, and a wealth of resources for continued learning, "Geoengineering the Climate" provides an indispensable starting point for students, policymakers, and curious citizens eager to understand and thoughtfully engage with one of the defining debates of our time.
