SURE THE MATH DOESN'T WORK UNDER MANY HUMIDITY/TEMPERATURE/ALTITUDE COMBINATIONS, SO THEY CAN NOT SPRAY IN A USABLE WAY EVERYWHERE, EVERYDAY.
When I sprayed crops and friends did weather modification, we has some hangar flying talks. With my spraying, I had to determine the amount of gallons and amount of which chemical in which concentration per gallon, generally in the range of a gallon per acre. Some farms took several flights.
My friends in their turbo pressurized twins had to figure the area to go so winds would carry induced rainfall to the areas contracted. They, too, often made several flights to the same area per day. It just didn't work if the humidity was too low or the winds not right.
From what I read about the mixture going into near the exhaust flow of jet engines, the amount had to do with the humidity, speed, and temperature at the altitude, and did not require a lot per mile. Much of the H2O was from the exhaust itself.
By 9-11-2011 and the no fly days it was blocking 2-3*F of AGW(depending on the area or city). In the 1990s, Pinatubo blocked 1.5*F of AGW. The original idea was Edward Teller's last writing.
I think the max the so called shield can do is around 5*F cooling in an area, and only in perfect conditions. So AGW and ocean warming added are increasing in the old hockey stick, still. They are running out of money and the world is running out of cheap oil.
I think it is time to stop most of the geoengineering efforts and go for the 90% emissions reduction ASAP. End the jet age, end coal power, end most diesel, and end slash and burn. Let the growth only economy collapse. Whether the chemtrails are real or not.
If they are real, the most important place for them is the Arctic, until the threat of passing the open ocean warming positive feedback loop and the tundra methane positive feedback loop are both back into a safer zone.
If they are not real, we can only hope that these tipping points will not be crossed as AGW morphs to reality as soots settle out, regular contrails go away like 9-11 on steroids, and warming in momentum is not enough. Plus no cheating is allowed with burning fossil fuels and slash without swift and violent stopping. http://www.skepticalscience.com/No-alte ... -down.html
