REDDING, Calif. -

Arguments surrounding geoengineering, more commonly known as “chemtrails”, were heard by the Shasta County Board of Supervisors Tuesday.

The controversial topic had the supervisors chambers packed with roughly 300 people.

Geoengineering was described as a manipulation of the weather by spraying chemicals into the atmosphere facilitated by the government.

Dane Wigington of Redding maintains a geoengineering website. He started off with a ten minute presentation on the issue.

“The contamination issue is a public health hazard,” Wigington said. “And we believe that disclosure is necessary, required and that's all we're asking, is disclosure of the heavy metal contamination and the UV issue. That's what we're asking for."

Wigington was followed by dozens of other speakers.

“People that are loading their planes with the chemical are dressed in complete hazmat outfits,” one man said. “So if this is not harmful, why are they in a complete hazmat outfit?”

Another speaker said “We’ve been led astray by the military/industrial complex and they’re responsible for the weather manipulation programs. They’re dark operations. That’s why they’re not out in the media.”

A different speaker said that geoengineering was, in part, responsible for wildfires.

“It’s because of the amount of aluminum why they can’t get these fires out,” she said. “And they go on burning for months at a time in other states and even in California.”

After three hours of testimony and board discussion, Supervisors voted to send the information to several agencies like: the Environmental Protection Agency, the California Air Resources Board and State and Federal legislators.

The county will also check to see if Lassen National Park has equipment that can measure in nano-particles because the county doesn’t have equipment that sophisticated.
