Scientists from Harvard have been working on it for a few years, and now, they are ready to conduct it.  They intend to spray the sky using high altitude airplanes, in order to block the sunlight and thus prevent global warming and cool the Earth.

They are prepared to start this experiment in early 2019, and even though they initially decided to use an aluminum spray, they changed their mind and opted for calcium carbonate instead.

Their aim is to “replicate” the climate-cooling effect a volcano eruption would have on planet Earth.

According to their plan, the Harvard team will be the first in the world to move solar geoengineering out of the lab and into the stratosphere, with a project named the Stratospheric Controlled Perturbation Experiment (SCoPEx).

The first phase, which is a US$3-million test that will include two flights of a steerable balloon 20 kilometers above the southwest United States, is planned to be launched in the first half of 2019.

This experiment would release small plumes of calcium carbonate, each of around 100 grams, which is about the same amount as the one found in an average bottle of off-the-shelf antacid. The balloon would then turn around to observe the dispersion of the particles.

SCoPEx builds on four decades of research on the environmental chemistry of the ozone layer in the Anderson/Keith/Keutsch groups, and it will use or adapt numerous high-performance sensors and flight-system engineering experience developed for this ozone research.

Harvard scientists believe that the analysys of these experiments will boost our knowledge beyond what is currently available within computer models or is measurable with confidence under laboratory conditions.

Additionally, this experiement is based on the studies of the effects of large volcanic eruptions on the planet’s temperature. In 1991, Mount Pinatubo in the Philippines erupted spectacularly, and released 20 million tonnes of sulfur dioxide into the stratosphere, which created a blanket around Earth’s stratosphere, and cooled the planet by 0.5 °C for about 18 months.

Our collective ability to lower the reduce greenhouse gas emissions and curb climate change worries scientists, governmental agencies, and environmental groups, so geoengineering is believed to be a possible solution. The ultimate goal is to reduce the warming on Earth, by reducing greenhouse gas emissions, sucking CO2 from the atmosphere, or limiting the sunlight that reaches Earth’s surface.

Researchers, in fact, intend to normalize geoengineering instead of testing how the particles white out the sun. There is actual data that proves the existence and history of geoengineering, which is a specifically weaponized weather modification.

Yet, this poses the question: do we actually know what happens when scientists spray calcium carbonate into the sky?

Is it possible that the whole narrative of climate change or global warming comes from the same people and institutions that work in or are related to geoengineering, including MIT (Massachusetts Institute of Technology), and the “defense” contractor Raytheon, with their strong ties to George H.W. Bush’s administration and their use of Raytheon’s staple Patriot Missiles?

Numerous people believe they have already felt the effects of geoengineering, and there is even evidence to prove it, like the rain tests obtained from the West Coast that tested positive for high levels of aluminum.

Many people claim that they can smell of static electricity in the moisture in the air, and there are also some who say that they can even see it happening, and experience flu-like symptoms then.

There are also many who find it difficult to believe that someone sprays the sky with aluminum or barium daily, and consider these claims conspiracy theories.

Yet, if it happens, can we predict the effects of such an experiment? What is the real goal behind such a practice?  If it is a conspiracy theory, what is the explanation of the constant aluminum traces in the rain?
