Keith's proposal is audacious at first, but in the course of this brief book he makes a convincing case.--
Slate--
Keith manages to keep the tone sober without ever sounding dull. His chapter on ethics deftly summarises some of the competing moral claims…Reading about proposals to alter the climate of an entire planet on purpose is dizzying. Yet scientists already talk of the dawning of a new geological age, the Anthropocene, named because humans, or rather, the industrial civilisation they have created, have become the main factor driving the evolution of Earth. [The Case for Climate Engineering emphasises] just how seriously the idea of deliberately altering the climate is being considered, both in scientific journals and among some governments…[Keith is] a guide for the undecided.

The Economist--
Keith deserves credit for directing attention to ideas he knows are dangerous. Accepting the concept of the Anthropocene means accepting that humans have the responsibility to find technological fixes for disasters they have created. But little progress has been made toward a process for rationally supervising such activity on a global scale. We need a more open discussion about a seemingly outlandish but real geopolitical risk: war over climate engineering.
