Critical Issues in Weather Modification Research
“Although 40 years have passed since the first NAS report on weather modification, this Committee finds itself very much in concurrence with the findings of that assessment we conclude that the initiation of large-scale operational weather modification programs would be premature. Many fundamental problems must be answered first. It is unlikely that these problems will be solved by the expansion of present efforts, which emphasize the a posteriori evaluation of largely uncontrolled experiments. We believe the patient investigation of the atmospheric processes coupled with an exploration of the technological applications may eventually lead to useful weather modification, but we emphasize that the time-scale required for success may be measured in decades.”
