Meteorologists envisage dotting the waters of the tropical western Pacific and the South China Sea with a grid of hundreds of thousands of “weather-control” rigs – solar powered devices designed to alter the local temperature on demand by pumping water between different depths. Theoretical models suggest that a sufficient number of rigs, under elaborate computer control, could be used to influence large-scale weather patterns, “nudging” them toward the least harmful of a number of finely balanced possible outcomes.
