OneFiercePuppy: I don't know what you're talking about for the first. Not at all.
How could you, you haven't watched the video that was the basis for this topic. I completely understand not wanting to invest the time, but then how can we have a meaningful dialogue about it?
OneFiercePuppy: Who are these scientists?
The documentaries conveniently show the name of the scientists as they speak. Do you want me to go back through both films and write down all the names?
OneFiercePuppy: What are they planning to spray?
Aerosols made of various materials such as sulfate, aluminum or barium.
OneFiercePuppy: How (what is the mechanism) will this prevent global warming?
Particles released by aircraft, balloons or artillery would block sunlight from reaching the surface of the Earth, creating a global dimming effect. The idea was inspired by observing volcanic eruptions and the effects the sulfuric acid aerosols they inject into the stratosphere have on Earth's climate.
OneFiercePuppy: Have you adjusted for externalities such as that when considering what's found where?
Have I? No, but then I haven't conducted scientific research on the subject, I merely posted two YouTube videos. You bring up some interesting points.
