One of the simplest approaches to reducing global temperatures is to shade the Earth from some of the sunlight with shields.
In the context of a rapidly warming Earth, scientists have begun to develop many different methods to minimize the effects of climate change.
Recently, István Szapudi, an astronomer at the Institute of Astronomy at the University of Hawaii (USA), proposed a method of using a solar shield to reduce the amount of sunlight shining on Earth.
It is known that the proposal titled `Solar radiation management with tethered solar shields,” by astronomer István Szapudi, was published in the journal Proceedings of the National Academy of Sciences, according to Phyx.org.
Scientists have long thought that one of the simplest approaches to reducing global temperatures is to shade the Earth from some of the sunlight.
For example, to balance the force of gravity and prevent the pressure of solar radiation from blowing away, the shield must possess a sufficient weight.
To solve this, astronomer István Szapudi proposed two innovative solutions: The shield would be anchored to a counterweight via a large rope, instead of a full-sized shield.
`In Hawaii, many people use umbrellas to block the sun when they walk around during the day. I was thinking, can we do the same for the Earth and thereby mitigate the impending climate change disaster?
According to this expert’s estimate, humanity could start with the goal of reducing solar radiation by 1.7%, the amount needed to prevent a catastrophic increase in global temperatures.
Of course, the above number is still beyond the ability to send materials to space with current technology.
The largest, most powerful rockets today can only deliver about 50 tons of cargo into low Earth orbit.
