Harvard Scientists Propose Dispersing Sulfates into Atmosphere

Academics from Harvard and Yale recently published a paper proposing a radical solution to climate change that involves spraying chemicals into the stratosphere to deflect and disperse sunlight off the Earth. Though they claimed their research was purely hypothetical, it explored the logistics of secretly putting aerosol sulfates into the atmosphere in the cheapest way possible.

Researchers Wake Smith and Gernot Wagner’s paper was published in the journal Environmental Research Letters and proposed the use of high-altitude aircraft, balloons, or naval weaponry to introduce Stratospheric Aerosol Injection (SAI) up to 65,000 feet above the Earth, as a solar geoengineering solution to climate change.

Curiously, the scientists questioned whether it would be possible to conduct this type of operation secretly, reigniting conspiracies over clandestine government chemtrail programs that many believe are already underway.

“Here we seek answers to three questions: if SAI deployment were to commence within the foreseeable future with the tools and technologies at our disposal, how would such deployment be physically achieved, how much would it cost, and could it be done in secret?” the authors said.

In the end, they decided the answer was that it was unlikely such an operation could be conducted furtively with existing technology, due to the thousands of flights needed to conduct the operation over the course of a year.

This concept of releasing material into the atmosphere to deflect sunlight stems from the eruption of Mt. Pinatubo in the Philippines in 1991. When this volcano erupted, its release of 20 million tons of sulfur dioxide created a cooling effect on the Earth’s surface in the Southeast Pacific, lowering average temperatures in the area by 0.5 °C for a period of 18 months. This became the impetus for a number of solutions scientists proffered to curb climate change over the past few decades.

The authors of this latest paper did offer a disclaimer saying, “we here make no judgment about the desirability of stratospheric aerosol injection.” Though, their paper went on to lay out a plan that proposed an extensive process hypothetically beginning in 2033. Their goal is to curb the average global temperature rise by about half a degree Celsius over a 15-year period.

The paper was picked up by a number of mainstream media outlets that touted their proposal as “ingenious” and “ambitious.” But those who have long questioned whether a program of this ilk may already exist wondered whether it could be part of a process to slowly introduce the idea to the public or gain insight into the public’s sentiment.

A similar experiment will be carried out by a team at Harvard called the Stratospheric Controlled Perturbation Experiment (SCoPEx), which plans to release small plumes of calcium carbonate into the stratosphere to achieve the same effect. Calcium carbonate is likely safer than sulfates, though no one is sure as to what the effect might be on global ecosystems if thousands of tons of particulate matter were released into the atmosphere.
