Global warming is considered one of the most likely causes of the destruction of life on Earth. Scientists have observed a sharp change in the climate of the planet and believe that the increase in temperature will inevitably kill our planet. Recently, the problem has become so acute that researchers from Harvard University have proposed a very risky method of reflecting excessive solar heat from the earth’s surface. If it doesn’t work, life can be destroyed much faster than previously thought.
Scientists propose to create a chemical barrier that will reflect the sun’s heat. To do this, it is necessary to spray sulphate aerosols on the lower layers of the atmosphere. Immediately there is a problem-in the world there is no aircraft that could lift heavy capsules with the smallest solid particles to a 20-kilometer height.
The researchers do not deny the possibility of creating such a device. They believe that this will cope with the aircraft with a narrow body, disproportionately large wings and two additional engines. The program of spraying aerosols, according to their calculations, would cost $ 3.5 billion, and maintenance costs — 2.25 billion This amount can afford a country that gives $ 500 billion on other programs to protect the environment. Hundreds of these aircraft can hold 60 000 missions per year.
The chemical barrier can eliminate some of the symptoms of global warming, but will not completely protect against it. The researchers believe that the running spray program is better not to stop. If the spraying stops, the rate of increase in temperature on Earth may accelerate, and humanity will have little time to adapt to new conditions.
Of course, spraying a large number of small particles into the atmosphere will change the view of the sky. In 2012, an article was published in the journal Geophysical Research Letters, which stated that sulfate aerosols are able to paint the sky white and make it five times brighter.
