One of the big problems facing mankind is that we are unwittingly changing the weather by burning fossil fuels. The extent to which this is happening, and whether there is anything we either can or should do about it is debatable. But what may come as a surprise is that humans have been trying to control the weather for longer than you might think. In fact, just about every bit of new technology that has come along has been used to attempt precisely that. The results? Total failure every time. Fascinating stuff, and with the climate debate ranging topical stuff as well.
