Asteroid dust could apparently be the Earth’s cure for global warming. If you’re picturing something like powdered sugar being sifted over a muffin or sprinkles on a cupcake, you’re not the only one. How on earth could this bizarre scenario help with climate change? And will everyone be choking on this dust from space?

Don’t worry about developing an allergy to this intergalactic powder: The dust would be spewed from an asteroid, equipped with a ‘mass diver,’ far out in space, and ideally, then act as a sunshade for Mother Earth. Scottish scientists say that by shading earth with a giant dust cloud, drastic climate change could be prevented more effectively alongside other methods, such as reducing emissions of greenhouse gases. It’s called geoengineering, which thinks about the global warming problem on a, well, more universal scale.
However, there are potential risks and dangers to this asteroid dust. One scientist pointed out that “a very large asteroid is a potential threat to Earth.” They would have to somehow “gravitationally anchor” the dust cloud (how they would do that is another subject entirely). He also admits that there’s no way to “fully test this dust cloud on a large scale to verify its effectiveness before implementing it.” Hmmm. Well, then, how would they do this without causing a real-life Armageddon? That is a question yet to be answered. What do you think of this proposed solution–genius, or reckless?
