What could possibly go wrong? Of course, the scientists will get lots and lots of government funding, and live pretty good lives with it
These researchers want to launch dust from the moon to help cool Earth
Imagine a world where global warming on Earth has meaningfully diminished. Fossil fuels are on the back burner. Affordable renewable energy sources run most of our activities. Oh, and there’s a cannon on the moon shooting lunar dust into space to help partially shield sunlight to Earth.
That’s one eyebrow-raising approach for cooling our planet proposed by a group of astrophysicists in a study published Wednesday in PLOS Climate. The team used computer simulations to model various scenarios where massive quantities of dust (and we mean a lot of dust) in space can reduce the amount of Earthbound sunlight by 1 to 2 percent, or up to about six days of an obscured sun in a year. Their cheapest and most efficient idea is to launch dust from the moon, which would land into orbit between the sun and Earth and create a sunshade.
Yes, the idea sounds like science fiction. Yes, it would require (a lot of) new engineering. Yes, there are more feasible climate mitigation tactics that can be employed now and in the near future. But the researchers view this rigorous physics experiment as a backup option that could aid — not replace — existing strategies to help humankind live on a more comfortable Earth.
Considering that most of their computer simulations have been wrong, from a bit wrong to spectacularly wrong, this won’t go well. But, they’ll piss away lots of your tax dollars for this pie in the sky idiocy.
(New Scientist) Launching a dust cloud from the moon to block sunlight reaching Earth could reduce global warming, but such a strategy may require more than a decade’s worth of research before it can be implemented. The risks involved with such an approach in terms of how it could affect agriculture, ecosystems and water quality in different parts of the world are also unclear.
They can run all the simulations they want, but, they really do not know the effects.
