It's funny how Dane Wigington explains ~06:00 into on the documentary film "Look Up", by George Barnes of Skyder Alert, how the goal of the patent "Stratospheric Welsbach seeding for reduction of global warming" is about "solar obscuration", to "block the sun". https://www.google.com/patents/US5003186 But reading the content of the patent tells us this: So the purpose of this patent Wigington refers to is not to prevent radiation from the sun to reach the earth's surface, but to convert trapped radiation (infrared) from the earth's surface into radiation further away from the infrared range which then can escape back into space. The principle is similar to how Welsbach mantles (gas mantles) work, hence the "Welsbach" in the title. What's even more funny is that this patent clearly discredits the method of deliberate aerosol spraying from airliners by adding metallic particles in the jet fuel. The patent states: In other words, the statement above is not the patented method described in the patent (Wigington seem to believe it is), instead the patent provides what is claimed to be a better solution (Welsbach seeding) that would not trap long wavelength radiation in the atmosphere. Greenhouse gasses such as CO2 and methane are especially good at absorbing radiation (trapping heat) in the infrared spectrum, which is what this patent claims to have the solution for. It's obvious this isn't a case of editing, Wigington clearly misspoke, or simply didn't pay attention to the actual methodology described in the patent. But considering how many irrelevant patents you find in this list http://www.geoengineeringwatch.org/links-to-geoengineering-patents/ it wouldn't surprise me if Wigington really doesn't care as long as the patents contain certain keywords such as "aerosol", "cloud seeding", ect.
