they weren't blocking United States citizens sunlight on purpose with money from tax payer dollars and not telling them about it in the 1940's
this chemtrailing phenomenon is recent....but nice try lil monkey
here is the news article from 2011
9. Government Sponsored Technologies for Weather Modification
September 30, 2011
Rising global temperatures, increasing population and degradation of water supplies have created broad support for the growing field of weather modification. The US government has conducted weather modification experiments for over half a century, and the military-industrial complex stands poised to capitalize on these discoveries.
One of the latest programs is HAARP, the High Frequency Active Aural Research Program. This technology can potentially trigger floods, droughts, hurricanes and earthquakes. The scientific idea behind HAARP is to “excite” a specific area of the ionosphere and observe the physical processes in that excited area with intention of modifying ecological conditions. HAARP can also be used as a weapon system, capable of selectively destabilizing agricultural and ecological systems of entire regions.
Another Environmental Modification (EnMod) program is that of atmospheric geoengineering, or cloud seeding, which has found new life since the global warming scare. Cloud seeding involves creating cirrus clouds from airplane contrails. Unlike regular contrails, which dissolve in minutes, these artificial contrails can last from several hoursto days. Once the artificial clouds have been created, they are used to reflect solar or manmade radiation.
At a recent international symposium, scientists asserted that “manipulation of climate through modification of cirrus clouds is neither a hoax nor a conspiracy theory.” The only conspiracy surrounding geoengineering is that most governments and industry refuse to publicly admit what anyone can see in the sky or discover in peer-reviewed research. The Belfort Group has been working to raise public awareness about toxic aerial spraying, popularly referred to as chemtrails. However, scientists preferred the term ‘persistent contrails’ to describe the phenomenon, in an attempt to move the inquiry away from amateur conspiracy theories.
Dr. Vermeeren, Delft University of Technology, presented a 300-page scientific report entitled, “CASE ORANGE: Contrail Science, Its Impact on Climate and Weather Manipulation Programs Conducted by the United States and Its Allies.” He stated clearly, “Weather manipulation through contrail formation… is in place and fully operational.” Vermeeren mentioned a 1991 patent now held by Raytheon, a private defense contractor, with “18 claims to reduce global warming through stratospheric seeding with aluminum oxide… thorium oxide … and refractory Welsbach material.” Authors of the study expressed concern that Raytheon, a private corporation, makes daily flights spraying these materials in our skies with apparently minimal government oversight. Raytheon is the same company that holds the HAARP contract with the US.
Other countries are also experimenting. The Chinese government announced in April, 2007 the creation of the first-ever artificial snowfall over the city of Nagqu in Tibet. China now conducts more cloud-seeding projects than any other nation.
