National Academy of Sciences debates spraying aerosols into upper stratosphere to combat global warming

Debate surrounding the possibility of geoengineering the earth’s climate by lining the atmosphere with aerosol particles has moved from idle speculation to serious consideration, and was a core topic of discussion at a recent National Academy of Sciences workshop.
However, a top Rutgers University professor warned at the meeting that tampering with the planet’s delicate ecosystem could create famines and droughts, threatening the lives of no less than a third of the world’s population.
The plan to shoot aerosols – dust particles – into the earth’s upper stratosphere in an attempt to cool the planet and offset the purported effects of global warming, should be considered as an “emergency response” to a climate crisis, according to Harvard University’s Dan Schrag, who told the workshop that such a crisis was already underway.
“I think we should consider climate engineering only as an emergency response to a climate crisis, but I question whether we’re already experiencing a climate crisis — whether we’ve already crossed that threshold,” Schrag said.
According to an NPR report on the meeting , University of Calgary’s David Keith urged the introduction of geoengineering experiments on a global scale and that they should be conducted “sooner rather than later”.

But Rutgers University professor Alan Robock warned that such experiments “could create disasters,” damaging the ozone layer and potentially altering the stratosphere by eliminating weather patterns such as the annual Asian monsoon rain season, which 2 billion people rely upon to water their crops and feed the population.
“Imagine if we triggered a drought and famine while trying to cool the planet,” Robock said.
As we have previously highlighted, discussions regarding the possibility of “geo-engineering” the earth’s climate to counter global warming by “shooting pollution particles into the upper atmosphere to reflect the sun’s rays” has stoked fresh concerns that similar programs are already underway, and that chemtrails are directly connected to such experimentation.

Chemtrails differ from ordinary contrails in that they hang in the sky for hours and are often observed to be emitted from planes that fly criss-cross routes, leading to the formation of ‘X’ and grid-like patterns in the sky. Chemtrails also directly effect localized weather by turning a clear blue sky into a hazy overcast.
Last year, a KSLA news investigation  found that a substance that fell to earth from a high altitude chemtrail contained high levels of Barium (6.8 ppm) and Lead (8.2 ppm) as well as trace amounts of other chemicals including arsenic, chromium, cadmium, selenium and silver. Of these, all but one are metals, some are toxic while several are rarely or never found in nature. The newscast focuses on Barium, which its research shows is a “hallmark of chemtrails.” KSLA found Barium levels in its samples at 6.8 ppm or “more than six times the toxic level set by the EPA.”
KSLA also asked Mark Ryan, Director of the Poison Control Center, about the effects of Barium on the human body. Ryan commented that “short term exposure can lead to anything from stomach to chest pains and that long term exposure causes blood pressure problems.” The Poison Control Center further reported that long-term exposure, as with any harmful substance, would contribute to weakening the immune system, which many speculate is the purpose of such man-made chemical trails.
As we covered in a previous in-depth report,  numerous universities and government agencies have been conducting studies in the field of geoengineering for years.
In addition, the Obama administration’s interest in exploring “geo-engineering” mirrors recent publications penned by the elite Council On Foreign Relations.
In a document entitled Geoengineering: Workshop on Unilateral Planetary Scale Geoengineering , the CFR proposes different methods of “reflecting sunlight back into space,” which include adding “small reflecting particles in the upper part of the atmosphere,” adding “more clouds in the lower part of the atmosphere,” and placing “various kinds of reflecting objects in space either near the earth or at a stable location between the earth and the sun.”
The proposals in the CFR document match exactly the atmospheric effects observed in the aftermath of chemtrail spraying.
