Normal jet contrails may form artificial cirrus clouds (contrary to the opinion that they always dissipate within 15 minutes) at very high/cold altitudes |
Contrails may form when emissions of hot, warm engine exhaust in the upper troposphere mix with the cool moist ambient atmosphere. Under certain atmospheric conditions (super-saturated with respect to ice), contrails can persist for several hours. If the atmospheric conditions are favorable for ice crystal growth these persistent contrails may grow and spread out to form contrail-induced cirrus clouds (e.g. Fahey et al., 1999). |

Artificial cloud cover decreases |
Contrails are most similar to natural cirrus clouds due to their high altitude and strong ability to efficiently reduce outgoing infrared radiation [heat that the Earth radiates back out to space]. However, they typically have a higher albedo [reflectivity] than cirrus clouds; thus, they are better at reducing the surface receipt [absorption] of incoming solar radiation [lowering Earths surface temp].

Contrail-induced cirrus causes slightly more heating than cooling of the Earths surface (contrary to most scientists unproven belief that they mostly cause cooling) |
The radiative forcing [global warming] due to a distinct pattern of persistent contrails that form into contrail-induced cirrus [clouds] near and over the UK is investigated in detail for a single case study during March 2009. Persistent contrails and contrail-induced cirrus exert a radiative forcing [global warming] in both the SW [short wave] solar spectrum and LW [long wave] terrestrial spectrum (e.g. Stuber et al., 2006; Karcher and Spichtinger, 2009). They reflect incident sunlight back to space thereby brightening the planet and leading to a negative SW radiative forcing that is associated with a cooling and they also trap LW radiation within the Earths atmosphere system leading to a positive LW radiative forcing that is associated with a warming. The net radiative effect of persistent contrails and contrail-induced cirrus is the sum of the negative and positive radiative forcing, resulting in a net forcing that is believed to be positive [warming].

Contrail clouds and artificial clouds produced by spraying powders of aluminum/strontium/barium are heating the Earth up instead of reducing global warming. |
Here's the lower troposphere global temperature graph showing a warming rate increase since 1997 when geoengineering started. Another proof that they are causing global warming, not stopping it. Are they really that stupid? Or are they causing it on purpose?  (SOURCE) |

In addition to the presence of contrail-induced cirrus clouds I believe that intentional spraying of metallic powders into the atmosphere has been happening since 1997 although governments won't admit it because it is an unproven scheme whose downsides are 1) ozone destruction (and subsequent increase of ultraviolet light reaching Earth), 2) aluminum poisoning of the land which reduces crop production (which is why Monsanto has been modifying the genetics of plants to be resistant to aluminum), 3) disruption of the natural balance of weather, causing droughts in some areas and floods in others, 4) increased incidence of alzheimers due to aluminum absorption from the air into the lungs. Proponents of this unproven scheme heartily believe that it cools the planet and that if the spraying stopped that warming would dramatically increase. It's like a stupid religion, all based on beliefs without facts. |
Since 1998 Lowell Wood and Edward Teller have been promoting aerosol spraying into the stratosphere as a simple and cheap counter to global warming. Lowell Wood believes that climate engineering is inevitable; it's a matter of time before the 'political elites' wake up to its cheapness and effectiveness. But a disturbing effect of enhanced dimming [of sunlight] would be the permanent whitening of day-time skies. A washed-out sky would become the norm. If the nations of the world resort to climate engineering, and in doing so relieve pressure to cut carbon emissions, then the concentration of carbon dioxide in the atmosphere would continued to rise and so would the latent warming that would need suppressing. It would then become impossible to call a halt to sulphur injections into the stratosphere, even for a year or two, without an immediate jump in temperature. It's estimated that, if whoever controls the scheme decided to stop, the back-up of greenhouse gases could see warming rebound at a rate 10-20 times faster than in the recent past, a phenomenon referred to, apparently without irony, as the "termination problem". Once we start manipulating the atmosphere we could be trapped, forever dependent on a program of sulphur injections into the stratosphere. In that case, human beings would never see a blue sky again.
