Conditioning, weakening, and destabilizing the atmosphere.EDITED video added.
I live in New York City, so I have not experienced any "chemtrail" spraying firsthand (as far as I know, chemtrail spraying is mainly in the midwest, etc.), so as far as I can guess, chemtrail spraying is mainly done to condition the atmosphere and weaken it...
1) so that the weather can become more chaotic.
2) and to make the magnetic pole shifting and ground frequencies more susceptible to HAARP.
The internet needs more people like you reporting what is going on in their neck of the woods (because people from all over the United States STAY SILENT.....there has been NO BP coverage from Gulf state residents, or disaster victims (floods, wildfires, tornadoes, etc.).
The news media has seemed to have a government gag order on important news (look at this 2009 video), so the only real "news" we can count on is what "WE the PEOPLE" provide on the internet.
...(I didn't know Hawaii was still in a bad way weatherwise).....THANK YOU!.
