L'alternativa razionale

In this very short book, David Keith recommends that a large-scale research program be started. The program would investigate whether climate engineering would be practical, and assess its practicality and side effects. By "climate engineering", Keith means spraying the upper stratosphere with sulfat Leggi tutto

It was a good read. I liked the insight into how sulfur dioxide can reflect sunlight before going on to explain the geopolitical nature surrounding its contention. The utilitarian nature of the world is what is mainly discussed as implementing geoengineering impacts can result in unfavourable outcom Leggi tutto

I found the book disappointing largely because I assumed it was written recently. It wasn't. It was published in 2013 before a lot of the more compelling evidence had been developed. Solar dimming has advanced a great deal since 2013. A number of researchers have come up with credible alternatives t Leggi tutto

A heroic attempt to comprehensively examine the implications of this field from science, to engineering (design, implementation), and impact it could have on the world, both natural and human. But he goes beyond that, looking at the social, policy, international relations, and what it would mean for Leggi tutto

A Case for Climate Engineering (2013) by David Keith is a very interesting short book that examines the use of solar geoengineering and it’s possible role in reducing the impact of climate change. David Keith is a professor of applied physics at Harvard who has studies climate engineering and was a Leggi tutto

A bit repetitive at some points. I would also like more details on the chemistry of the different pathways of aerosols after their exposure to UV. But this book is a start pointing for further reading. I now know I want to learn more on the subject.

A very important topic that should be the focus of more serious discussion and research.

Recommended reading If you are concerned about climate change and want to know what we can do to avoid the climate risks already locked in, you should read this book.

In a recent interview with David Keith, the author of “The Case for Climate Engineering,” humorist Stephen Colbert jokingly referred to climate engineering as the “All Chocolate Dinner”- a proposal that would allow humans to deal with global warming while spraying sulfuric acid into the high atmosph Leggi tutto

Solar geoengineering is a serious, complex topic that intertwines science, technology, economics, (geo)politics, policy, and ethics. In only ~100 pages, Keith actually deals with all these perspectives, citing the strongest arguments made by geoengineering's strongest opponents and proponents, then
