Should We Fertilize Oceans or Seed Clouds? No One Knows.
Gather scientific evidence on the feasibility and risks of marine geoengineering to guide regulation of research, advise Philip Boyd and Chris Vivian.
While the rating tells you how good a book is according to our two core criteria, it says nothing about its particular defining features. Therefore, we use a set of 20 qualities to characterize each book by its strengths:
Applicable – You’ll get advice that can be directly applied in the workplace or in everyday situations.
Analytical – You’ll understand the inner workings of the subject matter.
Background – You’ll get contextual knowledge as a frame for informed action or analysis.
Bold – You’ll find arguments that may break with predominant views.
Comprehensive – You’ll find every aspect of the subject matter covered.
Concrete Examples – You’ll get practical advice illustrated with examples of real-world applications or anecdotes.
Controversial – You’ll be confronted with strongly debated opinions.
Eloquent – You’ll enjoy a masterfully written or presented text.

While dozens of marine geoengineering projects have been proposed to tackle global warming, none has been deployed on the massive scale necessary to make a difference. The risk of catastrophic results is amplified by a lack of solid scientific data. Moving forward, researchers must build a solid, shared database, catalog drawbacks and benefits, develop a specific methodology, and work under vigilant policymaker oversight. This Nature article will remind readers that, while climate change is a critical issue, people must not make the situation worse by harming the oceans.
