Marine cloud brightening

Marine cloud brightening is a way to help keep Earth cooler by making the clouds in the sky brighter. Clouds are like a big blanket over the Earth and they help keep the Earth cooler. But if they get too dark, they can actually make the Earth hotter. So scientists have come up with a way to make the clouds brighter. They do this by spraying tiny droplets of sea salt and other chemicals into the sky. When these droplets mix with the clouds and water vapor, they make the clouds brighter and reflect more sunlight away from the Earth. This helps keep us cooler and protects us from getting too hot.
