Moon dust could help solve global warming, study says

It sounds like the stuff of science fiction but some experts think it may be the answer to saving Earth from climate catastrophe. Scientists in the US say dust launched from the moon could be a good way of blocking sunlight and alleviating global warming. According to their new study, moon dust would intercept a proportion of sunlight before it reaches our planet, acting as a'temporary sunshade'. Once the dust dissipates and floats away after a few days, more would be launched from the moon, allowing constant relief from the sun's light and heat. How exactly the dust would be launched from the moon is yet to be determined – although it could potentially be flung up using some kind of catapult.
