Harvard scientists launch experiments by blocking the Sun in the atmosphere - Popular Mechanics

To save the planet from overheating and the unpleasant effects of global warming. The Harvard scientists decided to spray the matter in the atmosphere. reflective sunlight.

If mankind can not prevent global warming and does not reduce the amount of harmful substances released into the atmosphere, then it will have to develop a sort of emergency survival scenario. This idea is not new, and the last 10 years have been actively discussed among geo-engineers. And it seems that scientists now have a plan.

One of these crazy ideas (at first sight) is to fill the atmosphere with particles of a substance that blocks sunlight. This experiment will be carried out by Harvard researchers who have already planned the first test for next year. The source of this idea was … the volcanoes. The mass emissions of ash and sulfur dioxide create an aerosol coating in the atmosphere, which reflects almost all the UV radiation from the sun. Thus, in 1991, the Pinatubo volcano, erupted in the Philippines, lowered the temperature of almost a whole Fahrenheit degree in the region for two whole years.

Scientists have posed the question: if only one volcano can globally influence the climate, will an 'artificial eruption cause a similar effect? Of course, we're not talking about lava emissions and similar catastrophes: they just want to spray a dense aerosol into the atmosphere and see if it helps to cool the planet a little bit. However, we should not forget that climate change in one place can cause a series of consequences in others. For example, last year, researchers found that the air pollution caused by the suspension of particles in the Gulf of Mexico could cause drought in Sub-Saharan Africa.

Fortunately, the upcoming Harvard scientists will have no global influence on the climate. The first tests will be modest: the balloon will rise to several kilometers in height and will spray less than 400 grams of calcium carbonate (an analogous less harmful than sulfur dioxide, which vomit volcanoes), and then one day will observe a cloud. The purpose of this experiment is to find out exactly how a suspension of matter in the atmosphere behaves, so that scientists can build a more accurate simulation.
