Harvard Scientists Say ‘Chemtrail’ Spraying Could Reverse Global Warming Without Damaging Ozone Layer: Claim Sparks Geoengineering Conspiracy Theory Speculation

A new study by a team of scientists at Harvard has sparked an uproar among members of the chemtrail conspiracy theory movement. According to conspiracy theorists, the study, which concluded that aerosol “chemtrails” could be used for “solar geoengineering” to reverse global warming without ozone layer depletion, proves that what has been dismissively termed conspiracy theory is real.

In the study, titled “Stratospheric solar geoengineering without ozone loss,” published in the Proceedings of the National Academy of Sciences (PNAS), researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) explained that previous geoengineering proposals to mimic the cooling effect of major volcanic eruptions by releasing light-reflecting sulfate aerosols into the stratosphere also involve the risk of further damage to the ozone layer due to the production of sulfuric acid from sulfur dioxide.

The ozone layer, according to experts, protects us from harmful ultra-violet radiation,

However, the team claimed to have found that aerosol containing calcite could be used in solar engineering to cool the Earth’s atmosphere and thus slow down or reverse global warming while neutralizing atmospheric acidity that damages the ozone layer.

“In solar geoengineering research, introducing sulfuric acid into the atmosphere has been the only idea that had any serious traction until now,” said study leader David Keith, the Gordon McKay Professor of Applied Physics at SEAS, and professor of public policy at the Harvard Kennedy School, according to the Harvard Gazette.

“This research is a turning point and an important step in analyzing and reducing certain risks of solar geoengineering.”

Previous research to limit the ozone damaging effect of geoengineering aerosols had focused on non-reactive aerosols. However, according to study co-author Frank Keutsch, the Stonington Professor of Engineering and Atmospheric Science at SEAS, the new study focused on finding suitable highly-reactive materials that would not damage the ozone layer.

“Instead of trying to minimize the reactivity of the aerosol, we wanted a material that is highly reactive but in a way that would avoid ozone destruction,” Keutsch said, according to the Harvard Gazette.

“Essentially, we ended up with an antacid for the stratosphere.”

The researchers found that calcite, a stable form of calcium carbonate contained in limestone, could reflect light and thus cool the planet while neutralizing atmospheric acidity that depletes the ozone layer.

However, the researchers emphasized that the best way to control global warming and climate change was by reducing human carbon emissions. According to the researchers, geoengineering only treats the symptoms, not the cause of the problem.

“Geoengineering is like taking painkillers,” Keutsch said, according to the Harvard Gazette. “When things are really bad, painkillers can help but they don’t address the cause of a disease and they may cause more harm than good.”

“We really don’t know the effects of geoengineering, but that is why we’re doing this research.”

But the latest research has set tongues wagging in the chemtrail conspiracy theory community.

“Get ready for the skies becoming even more bizarre than usual with the announcement that chemtrails could be used to save the planet!” a blogger declared.

“Chemtrails that have been considered ‘fake news’ and conspiracy theory are now set to be rolled out after Harvard boffins said they may repair damage we have done to Earth!”

According to chemtrail conspiracy theorists, governments are secretly spraying chemicals from airplanes for various alleged purposes. Some of the high-altitude airplane contrails we see are in fact chemtrails — a term invented by conspiracy theorists in reference to chemicals allegedly being sprayed secretly into the atmosphere by the government.

Many conspiracy theorists insist that chemtrails can be distinguished from ordinary airplane contrails.

Contrails are harmless condensation of vapor produced through the exhaust of aircraft flying at high altitudes. Chemtrails, on the other hand, contain harmful chemicals that last longer in the atmosphere after being sprayed from airplanes flying at high altitude.

Well-known proponents of the chemtrail conspiracy theory are Alex Jones (see YouTube below) and Chuck Norris.

A major preoccupation of chemtrail conspiracy theorists is analyzing time-lapse videos of airplane contrails to distinguish cases of chemtrail spraying from ordinary airplane contrails.

Some conspiracy theorists also claim that governments are also spraying psychoactive chemicals and biological agents into the upper atmosphere as part of a sinister “mind-control” agenda.

The “mind control” substances, which sink to the ground after being released into the upper atmosphere, are able to induce docility, tractability, and suggestibility in the masses. This makes people more susceptible to government manipulation and control, according to conspiracy theorists.

Last April, the Inquisitr reported a viral claim that NASA admitted to spraying anti-psychotic lithium in the upper atmosphere.

Some conspiracy theorists link chemtrail spraying with an alleged plan to inaugurate an evil global dictatorship known as the New World Order (NWO).

But other conspiracy theorists believe that the primary purpose of the alleged chemtrail spraying is to control the Earth’s climate and to reverse global climate change.

Several methods to control weather and climate are allegedly being implemented worldwide, according to conspiracy theorists.

Solar radiation management (SRM) seeks to cool the Earth by reducing the ability of the atmosphere to absorb solar radiation. This could be achieved through using aerosols that form artificial clouds to deflect sunlight.

Conspiracy theorists claim that researchers have been spraying light-reflecting sulfate aerosols into the air for years to form artificial clouds which cool the atmosphere by blocking sunlight.
