The CIA is funding a study examining various ways mankind can geo-engineer the planet -- blocking or limiting the sunlight that reaches the Earth, stripping carbon dioxide from the skies, seeding the clouds and so on.

The project, a panel called “Geoengineering Climate: Technical Evaluation and Discussion of Impacts,” is backed by the National Academy of Sciences, the National Oceanic and Atmospheric Administration (NOAA), NASA -- and the U.S. intelligence community.

That’s spy-talk for the CIA, William Kearney, a spokesman for NAS, told Mother Jones.

So why would the trenchcoat troops meet with the eggheads?

"It's natural that on a subject like climate change the Agency would work with scientists to better understand the phenomenon and its implications on national security," Edward Price, a spokesman for the CIA, told Mother Jones. He refused to confirm the agency's role in the study.

Conspiracy theorists love to argue that various world governments seek to control the weather; they cite “chemtrails” and cloud seeding and so on. The topic has even pervaded popular culture, from “The Simpsons” to “The X-Files.”

The group’s first two meetings, May 20 and June 19, were closed-door in their entirety, save for a list of participants.

On July 17 in Washington D.C., closed-door morning and evening meetings book-ended a public session, however, offering a peek into the group’s plans -- and it’s nothing worthy of Fox Mulder’s time, explained Edward Dunlea, study director with the National Academies.

“Nothing involved in this study is classified at all,” Dunlea told FoxNews.com. “We’re doing an evaluation. This is an assessment of what is known in the science literature about some of the proposed engineering techniques -- both solar-radiation management and carbon-dioxide removal.”

Dunlea declined to cite the CIA by name.

“All of our sponsors are interested in this topic as a part of the larger climate-change discussion, which has economic, environmental and national-security ramifications,” he said.

A 2008 study by the National Intelligence Council concluded that climate change posted a serious threat to national security.

“Climate change and climate-change policies could affect … domestic stability in a number of key states, the opening of new sea lanes and access to raw materials, and the global economy more broadly -- with significant geopolitical consequences,” it said.
