Developing countries study the cooling technology of the Earth

Scientists in developing countries plan to step up research on sunlight mitigation to prevent climate change.

At present, wealthy nations and prestigious universities such as Harvard and Oxford are taking control of the "solar geo-engineering" technology , which simulates massive volcanic eruptions creating a net of dust ash. The sun, therefore, can cool the Earth.

But a new study by a team of 12 scientists from China, Brazil, India, Thailand, Bangladesh, Ethiopia and Jamaica said that poor countries are vulnerable. It is best to warm up, therefore, to be more involved in efforts to combat climate change. Accordingly, developing countries must take the lead in the solar geo-engineering research.

Lead researcher Atiq Rahman, director of the Center for Advanced Research in Bangladesh, said that the idea of solar geo-engineering is unrealistic, but that the technology is slowly taking root in research in the world.

Solar geo-engineering studies may be supported by a $ 400,000 Solar Research Initiative (SRMGI), a new research project.

The foundation could help scientists in developing countries study the impact of solar geo-engineering in the area, such as droughts, floods or monsoons.

Rahman, however, argues that much of this technology controversy, which is too early to determine its effects, can be very effective but can be very harmful.

United Nations experts have expressed doubts about the viability of solar geo-engineering in economic and social terms, according to a draft climate report scheduled for publication in October. He said that the technology could interrupt weather patterns and could hardly stop once it had begun.

According to the Paris Declaration on Climate Change adopted by 197 countries in 2015, countries will work to implement measures to maintain a global average temperature rise of 1.5-2 degrees Celsius pre-industrial period.

However, according to two studies published in the latest issue of Natural Climate Change on April 2, the 2 ° C increase is no longer a safe threshold to protect the world from the effects of climate change. rear.
