The goal of scientists is to find out whether reflective particles dispersed in the atmosphere, affect the cooling of the planet’s surface.
The project called Stratospheric controlled perturbation experiment (Stratospheric Controlled Perturbation Experiment, SCoPEx), a part of a research program Harvard’s Solar Geoengineering. While most studies of the impact on the climate is sputtered in the atmosphere of chemicals, based on computer modeling, SCoPEx will conduct testing in the stratosphere of the Earth.
In the experiment, the balloon will soar to the stratosphere at the altitude of about 20 kilometers — and will release a small aerosol can of calcium carbonate. Once that happens, the connection will dissipate in the air, turned into a pillar with a length of about one kilometer and a diameter of 100 meters. Then the balloon will fly back and forth through the cloud within 24 hours, analyzing the behavior of particles and what is happening in the sky processes.
The experiment partially recreates the effects of the eruption of mount Pinatubo in 1991, which led to the most powerful release of aerosols into the stratosphere since the eruption of Krakatoa in 1883, Then, the experts recorded a temperature drop of 0.5 °C.

However, solar geoengineering has its drawbacks. Some studies show that spraying into the atmosphere a large number of particles reflecting sunlight, can have serious consequences, negatively affecting the crop, weather or ozone layer. The last factor is one of the reasons why the team SCoPEx works with calcium carbonate: previous studies have shown that this compound is the safest place for the stratosphere.
Even if the experiments are successful and will demonstrate that solar geoengineering is worth it to develop it, it will not be a panacea in the fight against global warming. Mankind still would have to reduce the amount of carbon emissions as it is the main cause of climate change, and solar geo-engineering, for example, will not be able to help with other related issues such as ocean acidification.
As reported by “Around the world. Ukraine”, blogger launched bread into the stratosphere to appreciate a new flavor.
