Scientists propose a new and inexpensive way to cool the planet

Scientists from University College London (UCL) have found that it is possible to use existing ordinary aircraft to reduce the Earth's global temperature. The results of a new scientific study on this were published in the scientific journal Earth.

Earlier, it was proposed to add special aerosol particles to the atmosphere to artificially cool the Earth. Such particles serve to reflect sunlight and reduce the average temperature of the planet. However, previous calculations suggested that these particles would need to be released to altitudes of up to 20 kilometres above the equator, which would require the development of special aircraft.

A new study by UCL scientists has found that releasing aerosol particles to an altitude of 13 kilometres above the Earth's polar regions, such as in the skies over Norway or Alaska, could also be effective. This would open up the possibility of using existing Boeing 777F cargo planes.

However, the new method has some drawbacks. Discharging particles to relatively low altitudes is less effective than when they are released to high altitudes. Therefore, to achieve the expected result, three times more of these substances would have to be used. This could lead to undesirable environmental consequences, such as acid rain in the atmosphere. It would also not be effective in reducing temperatures in the tropics - it is in these regions that climate change will have the strongest impact.

Nevertheless, scientists are carefully studying all the options for combating climate change. Using existing aircraft is much easier and cheaper than developing new equipment.

However, scientists also emphasize that using this method does not replace the need to reduce greenhouse gas emissions. The main and long-term solution to global warming is the need to drastically reduce the carbon footprint of human activities. Read 'Zamin' on Telegram!
