Geoengineering—or “planethacking,” as Eli Kintisch, in his smart, scary, sensational survey Hack the Planet, dubs the practice of large-scale deliberate human tinkering with the Earth’s thermostat—is to everyday carbon-footprint-reduction practices as stomach-stapling is to a sensible diet: it’s a risky, last-ditch solution to a problem of overindulgence, employed when more moderate schemes have failed. This is not to say such grandiose and drastic battleplans against global warming won’t work, or shouldn’t be tried in extremis—but only a sad and sober acknowledgement that we as a species, living in an era ironically labeled the Anthropocene, have indeed come to a shameful pass. Although Kintisch is extremely careful to present both sides of the controversy surrounding geoengineering with scrupulous—and highly readable—scientific precision, his catalogue of past geoengineering and envirohacking schemes gone awry (Hello Aussie cane toads, goodbye Aral Sea!) mounts up to an indictment of humanity’s ham-handed over-reaching in the light of Nature’s unknowability. Carefully describing plans to seed the stratosphere with sunlight-blocking aerosols—thereby rendering our familiar blue skies white!—and salt the oceans with iron in hopes of encouraging carbon-sequestering plankton, Kintisch simultaneously depicts the very human figures and emotional and philosophical forces behind the science and technology. He travels around the globe, attending conferences and interviewing major players, all while constructing entertaining historical context for the debate. Brian Aldiss’s recipe for a good science fiction tale—”Hubris clobbered by Nemesis”—has found its ultimate expression in this riveting non-fiction saga of planet-wreckers and those who believe they can glue Humpty-Dumpty together again.
