The sea is steadily rising, presently at ~3.4 mm/y, already costing Billions in Venice, on the Thames River and in New York City, to counter sea-level-related surges. Experts anticipate an accelerated rise, and credible predictions for sea level rise by the year 2100 range from 12 inches to above 6 feet. Study of the Earth's geologic history, through ice-core samples, links sea level rise to temperature rise. Since the lifetime of carbon dioxide in the atmosphere is measured in centuries, and it has upset the balance of incoming and outgoing energy, the Earth's temperature will continue to rise, even if carbon burning ceases. Engineering the Earth's solar input appears increasingly attractive and practical as a means to lower Earth's temperature, and thus, to lower sea level. The cost of engineering the climate appears small, comparable, even, to the already-incurred costs of sea level rise represented by civil engineering projects in London, Venice and New York City. Feasible deployment of geoengineering, accompanied by some reduction in carbon burning, is predicted to lower the sea level by the order of one foot by 2100 AD, negating the expected rise, to provide an immense economic benefit. The accompanying lower global temperature would reduce the severity of extreme weather, and restore habitability to lethally hot parts of the world. This book is primarily conceived to aid and inform the educated citizen: aspects may also interest climate workers.

This comprehensively updated third edition explores the nature and role of environmental management and offers an introduction to this rapidly expanding and changing field. It focuses on challenges and opportunities, and core concepts including sustainable development. The book is divided into five parts: Part I (Introduction to Environmental Management): four introductory chapters cover the justification for environmental management, its theory, scope, goals and scientific background Part II (Practice): explores environmental management in economics, law and business and environmental management’s relation with environmentalism, international agreements and monitoring Part III (Global Challenges and Opportunities): examines resources, challenges and opportunities, both natural and human-caused or human-aggravated Part IV (Responses to Global Challenges and Opportunities): explores mitigation, vulnerability, resilience, adaptation and how technology, social change and politics affect responses to challenges Part V (The Future): the final chapter considers the way ahead for environmental management in the future. With its well-structured coverage, effective illustrations and foundation for further, more-focused interest, this book is easily accessible to all. It is an essential reference for undergraduates and postgraduates studying environmental management and sustainability, and an important resource for many students on courses including environmental science, environmental studies and human geography.
