September 11, 2001 Airline Groundings: Contrails Affect Daily Temperature Range
All flights were grounded after the September 11, 2001 attacks on the twin towers. A team of NASA scientists noticed that it got much colder that night than usual. They came to the conclusion that cirrus clouds generated by aircraft contrails were trapping heat at night. This study changed world and sent the airline industry into a tail spin trying to figure out how to deal with their contrail conundrum. It is possible that aircraft contrail induced cirrus clouds are trapping more heat than their CO2 emissions meaning the airline industry could incur hefty carbon tax charges if they don’t create “less warming and more cooling clouds.”
Before 9/11/2001, one could make the argument that contrails creating clouds was just pollution. After this monumental study, scientists and geoengineers have been trying to figure out how to alter jet fuel> to create clouds that ONLY cool the planet and have no intention on stopping the creation of artificial clouds or removing these clouds all together.

Admires noted that President Gerald Ford signed an international weather modification act in 1976 and shortly thereafter was able to ski on fresh snow at Vail. Colo. Rep. John Fowler, D-Newtown, observed that airlines, in ads for ski excursions, promise fresh snow or your money back. David Horner of Columbia, an employee of the National Weather Service, declined to express an opinion about Admires opinions. Nor would he comment when Fowler said he had read the Russians were diverting jet streams to make it rain or arid land near the Black Sea, possibly influencing world weather.

FAA Scientist: We Want Clouds By Day, None By Night
Contrails during day cause cooling because of reflecting of sunlight back into space. During night, they trap infrared heat causing heating. So it is a balance between the two time intervals. We would like to have more CICs (contrail-induced cirrus clouds) during day and none during night. FAA Scientist: We Want Clouds By Day, None By Night
#CirrusCloudsMatter Geoengineering with Cirrus Cloud Seeding
If the time and place of seeding is selected with care, the climate effect of cirrus thinning can be enhanced. For that, only the long-wave warming effect of cirrus clouds should be targeted, and their solar effect should be avoided. This can be achieved if seeding is limited to high-latitude winters or to nighttime seeding.
