Weather Modification

Social And Ethical Issues

The use of weather modification techniques is often surrounded by controversy. An increase of precipitation over an area might be of benefit to some individuals in the area, but a disadvantage to others. For example, suppose that the owner of a private ski resort wants to have clouds seeded in order to increase snowfall over his or her property. If that effort is successful, the ski area benefits, economically. But other individuals and businesses in the area might suffer from this change in the weather. As an example, the county or state might have to pay more to keep roads and highways clear of the additional snow.
