Hackthe Planet: Science s Best Hope or Worst Nightmare for Averting Climate Catastrophe by Eli Kintisch
Dangerousjourney
Forthe time being, however, all of the existing plans and proposals are just armchair geoengineering, as Kintisch putsit. And the cast of armchair geoengineers is still very small. The result isthat both books cover a lot of the same ideas and quote many of the samesources, and both have in-depth chapters about two particular options:fertilizing the oceans with iron, and ships spewing cloud-brighteningparticles. Kintisch s book, though, offers up more examples of geoengineering.One is a proposition by the nonprofit Ice911, started by California-basedengineer Leslie Field, to protect sea ice from melting by covering it withsacks full of silicon beads. Another is a scheme put forward by atmosphericscientist Brian Toon, who proposes modifying coal-fired power plants to belchthe chemical carbonyl sulphide at ground level, from where, Toon figures, itwill eventually be carried up to the stratosphere([ strt?usfi?]【气】同温层;平流层) and turn intolight-reflecting sulphates.
Kintischalso digs deeper than Goodell into explaining the details of how geoengineeringmight work and why it would be so difficult to dowell. A reporter for the journal Science who regularly covers geoengineeringfor the journal s ScienceInsider blog, Kintisch likewise takes an insider sview in Hack the Planet. That s not to say Kintisch argues in favour ofgeoengineering, but that he writes from firmly within the world of science, andfor an audience who s comfortable with science, too. He never explains the term hack in the title, for example, which is borrowed from computer hacking andreflects the idea that geoengineering involves interfering with fundamental aspectsof the climate to change how the whole system works. For this reason,scientists and other science-literate readers especially those who already have some familiarity with geoengineering will probably prefer Kintisch s book over Goodell s.
