GO Exploring the Universe: Control of Weather...."there is little doubt that one could carry out analyses needed to predict results, intervene on any desired scale, and ultimately achieve rather fantastic effects .... Extensive human intervention would deeply affect the atmosphere's general circulation, which depends on the earth's rotation and intensive solar heating of the tropics. Measures in the arctic may control the weather in temperate regions, or measures in one temperate region Ao critically affect another, one-quarter around the globe. . . . There is no need to detail what such things would mean to agriculture or, indeed, to all phases of human, animal, and plant ecology....... ' All this will merge each nation's affairs with those of every other nation more thoroughly than the threat of a nuclear or any other war ..
