Strange weather The Boston Globe
Humans have long dreamed of controlling the weather. Some scientists are still trying to make that dream a reality.
cloud seeding: The late 19th and early 20th centuries saw an abundance of 'pluviculturists' who attempted to draw rain out of clouds by methods ranging from shaking them with artillery blasts to 'seeding' them with compounds such as electrified sand, as shown in this illustration from the early 1920s.

global cooling: To counteract global warming, John Latham of the National Center for Atmospheric Research has proposed a system of enormous eggbeater-like turbines that would stir up seawater, thickening the cloud cover to reflect more of the sun's energy back into space.
