For the past few years, a European collaboration called IMPLICC (Implications and Risks of Novel Options to Limit Climate Change) has been looking at what it might mean to engineer the climate, by reducing the amount of sunshine that reaches the Earth's surface. A lot of IMPLICC's work, like much else in climate science, has taken the form of computer modelling. In its case the models try to mimic the effects of things like putting veils of reflective particles into the stratosphere, or brightening the clouds over the oceans. Some researchers, however, want to go beyond modelling. They wish to experiment in the real world. This move to a practical project has proved controversial. Some people worry that tinkering deliberately with the atmosphere may cause more harm than good. Others fear that if geoengineering is shown to work it will, by offering a palliative for the problem of global warming, let politicians put off difficult decisions that might lead to a permanent solution. As Clive Hamilton, a philosopher critical of much of the thinking behind geoengineering research, pointed out to the meeting, though the environmental effects of such experiments may be nugatory, their effects on the way people think could be more profound, and much less easily contained.
