Time for a Change


  • Vincent J Schaefer Schenectady, New York


It has been more than forty-four years since I spread six pounds of crushed dry ice into a cloud over the summit of Mount Greylock in Massachusetts and triggered a fall of snow from a supercooled cloud. While the snow probably did not reach the ground, it inaugurated a tremendous amount of publicity, research, entrepreneurship and controversy. Within a few years, preposterous claims were being made to farmers, local governments and others for the control of the local precipitation patterns, rainfall, the reduction of hail damage and other weather related phenomena.
