In the heart of Silicon Valley in Palo Alto, California, there’s a group of retired physicists and engineers working on a nozzle to save their grandchildrens’ lives. The team, affectionately dubbed “the Old Salts,” designed the nozzle to spray sea salt particles in a specific size and concentration into the air. Once finished, it’ll be used to inject the substance into the skies over certain regions of the world.

It’s all part of an experiment to see if this approach can “brighten” clouds so they’re capable of reflecting more sunlight away from the Earth. While the tests would be small, they will attempt to uncover whether a larger scale operation like this could cool downthe planet—albeit temporarily. Then…
