Its moon’s turn to save Earth from global warming. Know how

The concept called ‘solar shield’ by the researchers involves mining millions of tons of dust from the moon and shooting it into the space to make a protective covering around the planet New Delhi: Researchers at the University of Utah have come up with a unique proposal to mitigate global warming – a plan to cover Earth with a shield of moon dust to scatter sun light. The concept called “solar shield” by the researchers involves mining millions of tons of dust from the moon and shooting it into the space to make a protective covering around the planet. “A really exciting part of our study was the realization that the natural lunar dust grains are just the right size and composition for efficiently scattering sunlight away from Earth”, Bromley told the Guardian. The plan if ever put into action would require millions of tons of moon dust to be mined, sifted and loaded into a ballistic device like an electromagnetic rail gun, and fired into the space every year to maintain the solar shield.
