New method of

British scientists propose a completely new method of cooling the Earth by creating 'artificial volcanoes'.

According to the initiative of British geotechnical and equipment experts, to prevent global warming, a giant sphere, the size of a stadium with a duct (like a pipe), is used. Soft rubber for watering garden plants) is over 20km long and spraying tons of chemicals to stratosphere.

British experts believe that spraying chemicals on the stratosphere will help to cool down the Earth.

Scientists calculate that droplets of sulfate solution and aerosol particles will reflect solar energy back into the universe, not letting the energy source heat up the Earth.The device works based on the principle of volcanic action, every time they erupt, the global average temperature drops.

Currently, researchers are preparing to conduct small-scale device testing. A very small ball is raised to a height of 1 km, then sprayed water into the atmosphere to assess the effectiveness of the method.

One of the authors of the project, Oxford University professor, Hew Hunt, said: "The advantage of the method is that we can adjust the spray speed of the particle into the atmosphere."

However, the 'artificial volcanic' method also has drawbacks. For example, chemical spraying will lead to accumulation of carbon dioxide in the atmosphere, making the sea toxic. On the other hand, the influence of the device on the weather is not predictable.

Previously geotechnical experts have proposed many ways to protect the Earth from warming up like using a giant mirror, placed on orbiting satellites to reflect light back into space. . The researchers also came up with the idea of ​​growing light-loving plants, spraying seawater into clouds to create reflective effects as well as painting streets and roofs into white. In addition, there is a project to spray iron powder into the sea water, destroy wollpack clouds , absorb greenhouse gases from the air, take heat from the ocean.

Saving the Earth from heat up is now very urgent, cannot be delayed any longer. Recently, the UN International Energy Agency announced that the concentration of carbon dioxide in the air causing a greenhouse effect is increasing rapidly. That situation led to last year being the hottest year in Earth's history.

In early June Stanford University researchers warned that the average summer temperatures in the coming decades will rise unpredictably due to global warming. Climate change focuses on the middle region - Europe, China and North America. In tropical countries in Africa, Asia and South America, summer temperatures will gradually "escalate" over 20 years.
