A new documentary video produced by an amateur climate researcher has the online world buzzing with a new debate:Do human-made clouds affect the climate more than greenhouse gases like CO2?The 25-minute presentation explains that humans are dispersing cloud-making chemicals, silver iodide in particular, into the atmosphere globally at high altitudes for the purpose of increasing precipitation.According to Dave Dahl, the writer and producer, cloud seeding programs have proliferated across the US and around the world since the invention of silver iodide by Dr. Bernard Vonnegut (brother of the famous author Kurt Vonnegut) in the 1960s.”We started cloud seeding in the 1940s using dry ice,” says Dahl. “But in the 1960s we started using silver iodide, and its use has grown exponentially every decade since then. Now the majority of states in the US use silver iodide for weather modification to increase precipitation.”Dahl says he recently became aware of several facts that compelled him to produce the movie.

“I had been studying artificial clouds for over six years before discovering that we spray silver iodide at high altitudes around the entire Earth, and we do that in many states before every single rain or snow storm. Counties in dry states like California believe they can get 10-15% more water cheaply by expanding storm clouds in their area. But what happens when every state is doing it? There’s only so much water in the atmosphere, and every state wants it.”

Dahl also says that the spraying of silver iodide before storms causes jet aircraft to form icy clouds with their exhaust steam, which explains a lot of the persistent tracks in the sky from jet condensation trails.

Other factors like forest fires can also cause persistent contrails, he notes. But he also reports that when he has seen persistent contrails, or “chemtrails” as they are often called, there happens to be a cloud seeding program nearby in every case, including in other countries. “If you see persistent contrails, chances are there have been cloud-seeding activities near you.” He says that fact can easily be verified through local government documentation.

“The combustion of jet fuel produces water,” says Dahl, “and the water is emitted as steam that instantly freezes and bonds with the silver iodide particles. We’re increasing cloud cover through our precipitation enhancement programs. And our most knowledgeable scientists say that clouds affect the climate more than the expected effects of greenhouse gases like CO2.”

According to Dahl, ice clouds formed by aircraft impose a greenhouse effect, or “igloo effect” by preventing heat from escaping. He also reports that cloud-seeding programs across the US and in over 50 countries use incendiary flares to disperse the silver iodide, which Dahl says include strontium, aluminum and magnesium.
