Right now, scientists are working on ways to minimize the catastrophic impact of global warming. But they're not designing hybrids or fuel cells or wind turbines. They're trying to lower the temperature of the entire planet--with huge contraptions that suck CO2 from the air, machines that brighten clouds and deflect sunlight, even artificial volcanoes that spray heat-reflecting particles into the atmosphere. This is the radical and controversial world of geoengineering, which only five years ago was considered to be "fringe." But as Jeff Goodell points out, the economic crisis, combined with global political realities, is making these ideas look sane, even inspired. Goodell himself started out as a skeptic, concerned about tinkering with the planet's thermostat. There are certainly risks, but Goodell believes the alternatives could be worse. In the end, he persuades us that geoengineering may just be our last best hope--a Plan B for the environment.--From publisher description.
