The consequences of using that can be unpredictable.
Scientists are proposing a very controversial way to combat climate change, which is the spreading of chemicals that reduce sunlight in the Earth's atmosphere, reports the Daily Mail.
The method of "injecting aerosols into the stratosphere" (SAI) can reduce the rate of global warming by half.
The study was conducted by researchers from Harvard Universities and Yale University and was published in the journal Environmental Research Letters. The idea was to spray a large amount of sulphate particles in the lower stratosphere at altitudes up to 19 kilometers.
Scientists say they can provide sulphates specifically designed for high altitude planes, balloons or big guns. The report recognizes, however, that this method is purely hypothetical.
There is no technology or aircraft yet for adaptation, but the team says the system can be created in 15 years. They claim that "the development of a new oil tanker built for this purpose offering" significant advantageous opportunities "and that it will not be" technologically complicated or prohibitively expensive ".
The cost of running the ISC system is estimated at $ 3.5 billion and the current cost at $ 2.25 billion a year.
"We do not impose the SAIs, but simply show that a hypothetical deployment program, although still very vague, but ambitious, would have been technically technically feasible 15 years later. It would also be remarkably cheap.
The team recognizes that there are some risks. It will be necessary to coordinate several countries in both hemispheres. In addition, SAIs could endanger agriculture, cause drought or provoke extreme weather conditions.
Hergot Wagner School of Engineering at Harvard University and co-author of the study said:
"Given the potential benefits of reducing the projected average increase in radiative forcing by a certain date in the future, the numbers show the incredible economics of solar geoengineering. Dozens of countries can finance this ?? program, and the technology required is not particularly exotic. "
The proposals do not address the problem of increasing greenhouse gas emissions, the main cause of global warming.
Philip Thalmann of the Ecole Polytechnique de Lausanne, an expert in climate change economics, said the system would be more expensive and "much riskier in the long run", as opposed to reducing greenhouse gas emissions.
And David Archer, Department of Geophysical Sciences at the University of Chicago, said: "If future generations could not pay their climate bill, they would have all my warming."
Why solar geoengineering?
In 2013, the Scientific Advisory Board of the European Academies (EASAC) published a report on the frequency of extreme weather events. Since then, there has been a steady growth of this type of events
To cope with such adverse weather conditions, they formulated recommendations on how the EU can better protect its citizens from climate change.
1. Information.
The report says that to better cope with problems, it is necessary to understand how global warming affects extreme weather conditions, to study it and to simulate it.
2. Thermal wave.
On the European continent, heat waves can vary considerably and have a very different impact. Understanding the nuances of these phenomena is essential to get through the storm.
3. Flood protection and early warning.
It should disseminate good practices in the field of flood preparedness and flood protection in Europe, including information and prevention.
4. agriculture.
The report states that the agricultural sector in general needs to be improved. Steps should be taken to increase resilience to the extreme climate.
5. Strengthening knowledge on climate change.
The study showed that it is essential that we consider adaptation to climate change as an ongoing process. To do this, long-term observations, analysis and modeling of the climate around the Earth are an integral part of a robust and flexible adaptation strategy to climate change.
6. Politics changes.
Several obstacles, namely physical, technical, psychological, financial and institutional, must be overcome.
