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...

"High-quality geological models are crucial for ground engineering projects, but many engineers are not always at ease with the geological terminology and analysis presented in these models, nor with their implications and limitations. Project engineers need to have a sound comprehension of the geological models presented to them, and to be able to discuss the models in so far as they might impinge on the design, safety and possible budgetary or time...
