The earth needs to cool down, and a shower of bling could be the way to do it. Scientists are interested in depositing diamond dust in the atmosphere to reflect sunlight and cool the planet. Although the use of diamond could be more efficient and safer than the use of other particles, the price may not allow the feasibility of such a diamond throw.

That climate change has more of a toll on Earth, scientists are considering methods to cool the atmosphere. One method being discussed is a solar geoengineering technique that involves depositing sulfur dioxide particles in the stratosphere to “mimic the natural cooling effects of volcanic eruptions” and reflect solar radiation away from the planet, said Popular Mechanics.
