The Israel 4 Cloud Seeding Experiment: Primary Results
4 November 2024 | ZeroGeoengineering.com | “…the results of the Israel 4 experiment are consistent with the hypothesis that seeding has no positive effect at all.”

“The experiment was stopped with the conclusion that the effect of operational seeding according to current best practices is small. Given the inherent variability in daily rainfall, the results of the Israel 4 experiment are consistent with the hypothesis that seeding has no positive effect at all. The Israel Water Authority accepted the final result of Israel 4 delivered by the steering committee and used it to weigh the cost of conducting operational seeding against the value of the expected additional rainfall that would result. That analysis led to the decision to end the experiment and also to stop operational seeding.”
