As the Earth continues to move toward a warmer climate, scientists are working on strategies to artificially calm the planet if the situation is really bad.But many plans come with a range of consequences, including changes in precipitation that can lead to droughts in some parts of the world.
In a new assessment of engineering geology techniques, researchers found that a method known as cloud thinning could be the best bet to fight climate change.
Researchers at the University of Zhejiang in China say it is possible to limit global warming by limiting the coverage of high-altitude cloud clouds.
This can be done by spraying powder above the clouds, which would push the ice crystals to form and eventually decrease because of their weight, according to the newspaper "New Scientist".
The deliberate reduction of the high-altitude cloud cover and the reduction of its thickness could reduce global warming "by modifying the long-term radiative forcing of thin clouds," the researchers said.
The team is also studying the possibility of reducing "solar glare" by spraying the atmosphere with aerosol or so-called aerosols to combat global warming by turning more sunlight into space.These clouds are placed in the sky and can help reduce high temperatures without having a significant impact on precipitation.As well as a third solution is the adoption of a method called "brightness of marine clouds" that can provide a greater reflection of solar radiation, and from the cooling of the earth.
The researchers found that all these strategies had already changed the average global rainfall during simulations, and although rainfall levels were no longer normal, the strategies showed far fewer side effects.
