00:03Our planet is getting warmer. There's no doubt about that. And it appears as though our addiction
00:07to fossil fuels is more resolute than our desire for survival. So aside from reducing our usage
00:12of burnable fuel, how can we avert climate catastrophe? According to scientists, maybe
00:17bubbles in space? The idea brought forth by MIT isn't exactly new, but it has evolved. First
00:22conceived in the 1980s as a giant disc made of lunar regolith blown into glass. But now scientists
00:27say not only is the idea not necessarily a bad one, but using different materials could mean
00:32it's the most feasible option for combating increased global temperatures. Science alert
00:36reports the sun shield would be built from something like molten silicon, which would then block
00:40particular solar wavelengths of light. And best of all, the futuristic human saver could be inflated
00:45in space, meaning building it would be considerably easier than other Earth-based options. Though some
00:50say that even though we could easily get rid of the space bubbles if problems arose, the effects it has
00:54on Earth would take time to correct in the event of a problem. So how big would this giant sun
00:58shield
00:58have to be? Experts say that the space bubble shield, when all pieces are joined together,
01:03would need to be around the size of Brazil to save us from climate catastrophe.
