First Drone for Cloud Seeding Used in Nevada but is Seeding Even Safe?

“We have reached another major milestone in our effort to reduce both the risks and the costs in the cloud seeding industry and help mitigate natural disasters caused by drought, hail and extreme fog,” said Mike Richards, President and CEO of Drone America, which provided the aeronautics expertise to get the aircraft off the ground.

But is cloud seeding even safe?  And these days, who do you turn to for discovery of information to make that decision for yourself because we have enough examples and past behavior to know we can’t trust main stream media or our government “leaders” to provide unbiased, accurate information.

You also can’t just “google it” because the first few returns or even pages of returns from google are now suspect given the algorithms they use to provide returns that includes sponsors and weighted friends.

On the Pro Side:

This Scientific American article from 2009 seems to be positive about seeding but casts doubt that seeding would help drought at all!

“If they are in a drought, they wouldn’t be able to draw enough from cloud seeding, just for the lack of clouds. You treat the storms you have, so cloud seeding certainly isn’t going to bring you out of a drought.”

This North American Weather Modification Council Site is absolutely pro (and of course why wouldn’t it be, given its mission):

“Silver iodide is the primary seeding agent used in cloud seeding. Its tremendous efficiency as an ice nucleus allows it to be used in minute quantities. Silver iodide has been extensively reviewed as to its environmental safety during the last half-century. The published findings of this research clearly show no environmentally harmful effects arising from cloud seeding have been observed, or are expected to occur. “

No link to the published findings provided.

Most documents found from government sources claim no damages caused by seeding going back to 1974, like this:

The effects of the weather modification activities on people, places and the ecology are prime considerations in planning and carrying out the projects.  Seeding with silver iodide will not cause serious ecological consequences.  Crushed dry ice soon disappears, and the propane concentration used in fog dispersal is below the danger limit of 100 ppm.  Metallic chaff fibers dispensed during lightning experiments have no known impact on the ground environment. Project leaders minimize such dangers by careful planning and by monitoring forecast and warning services.

Silver iodide, propane, metallic chaff fibers?!    A search on the latter results in hundreds of thousands of articles on chemtrails.

I think about how I run my own little place on Earth.  I don’t let little bits of plastic or styrofoam be on the ground because birds eat them.  They’re probably as full of plastic as sea fish but they don’t die fast from it.  They starve as their stomachs fill which non-food stuff.  So the idea that metallic chaff fibers don’t hurt anything doesn’t ring true to me.  What about the silver iodide?

From the Con Side:

From toxnet.nlm.nih.gov:

Human Toxicity Excerpts:
Seven cloud seeding operators with extensive exposure to silver iodide knew of no persons who had experienced any ill effects due to silver iodide, despite the fact that their hands may have remained yellowed for weeks.
[USEPA; Ambient Water Quality Criteria Doc: Silver p.C-26 (1980) EPA 440/5-80-071] **PEER REVIEWED**

… DEVELOPMENT /OF ARGYRIA (POISONING BY SILVER OR A SILVER SALT WHICH LEADS TO A PERMANENT ASHEN-GRAY DISCOLORATION OF THE SKIN, CONJUNCTIVA, AND INTERNAL ORGANS)/ FROM INHALATION THROUGH OCCUPATIONAL EXPOSURE APPEARS TO BE VERY SLOW & MAY REQUIRE YEARS.
[American Conference of Governmental Industrial Hygienists, Inc. Documentation of the Threshold Limit Values, 4th ed., 1980. Cincinnati, Ohio: American Conference of Governmmental Industrial Hygienists, Inc., 1980., p. 367] **PEER REVIEWED**

A study by a Mr. Johnny Micou who concluded:

The question is not that is cloud seeding harmful, but how harmful. It is obvious that it is significantly harmful. So far, programs such as PGCD have not provided effective monitoring and sampling to demonstrate that the silver concentrations in the water and soil caused by cloud seeding are at “safe levels.” To test for silver in the water and soil, the methods are sophisticated and require the latest in technology, along with standards set by such agencies as the EPA.(7) Without such testing, such programs must be stopped immediately. There is too much at risk for their experimentation.

So this questionable practice is now to be performed by drones. Leave your comments.
