Cloudbusting is already illegal. There are laws almost everywhere that could be used to ban cloudbusting if the prosecutors wanted to enforce them. In America, the Wilderness Act makes it illegal to "alter the pristine character of a designated Wilderness Area. That would include altering the weather of such an area, and since there are many such designated areas, and the typical cloudbuster operation covers so much ground, it is impossible to use one in the western states without violating that law.
The Endangered Species Act makes it illegal to do anything that affects the habitat of an endangered species, and there are so many of them that any orop would violate that law also.
The National Environmental Policy Act makes it a requirement to hold public hearings to allow the public to commnent before doing anything that would affect the environment.
The National Oceanic and Atmospheric Administration has a requirement that any weather-modification project must notify them at least ten days in advance of the start of operations. There is a $10,000 fine for failure to notify them.
In Australia, all weather modification needs a specific act passed by the legislature, and is not allowed without such an act. In the European Union, international human rights agreements forbid doing any scientific experiments on people without their consent, so to do a weather-control experiment it would be necessary to get the consent of every person in the area to be affected, or it would be a violation of the rights of anyone who did not give consent to be experimented upon.
There are also financial liability issues involved. In several American states, cloudseeders are required to have insurance coverage to guarentee they can compensate anyone whose property is damaged by their operations. Those laws would also apply to cloudbusting.
When Trevor Constable wrote an article about his using an aircraft for airbourne cloudbusting operations in Hawaii, I contacted the Federal Aviation Administration and told them about it. I sent them a picture of the airplane that Constable had published in his article about it, showing the equipment attached to the outside of the small airplane. They investigated, and the pilot had his license suspended for a time. It is illegal to attach anything to the outside of an aircraft that might alter the flight characteristics of the aircraft. This is an excellent example of how activists can use existing laws to obstruct atmosphere abuse without having to convince anybody about the effectiveness of cloudbusting.
So cloudbusting is already illegal almost everywhere. Anyone doing cloudbusting is in violation of several laws that already exist. What we need to do is be creative in thinking up ways to get those laws enforced without having to convince the scientific community or the government that cloudbusters work.
The Animal Rights movement is one good example of a group that uses tactics that can be used by a small minority to put pressure on evildoers despite lack of majority suport.
By exposing the ecological problems caused by his cloudbusting, I have been able to persuade several people to stop donating to DeMeo's research fund. This reduces his ability to go on cloudbusting expeditions.
