Marine Cloud Brightening

Marine Cloud Brightening is a proposed climate intervention technique aimed at reflecting more sunlight away from the Earth's surface to combat global warming. It involves enhancing the brightness of clouds over the ocean by spraying tiny sea salt particles into the atmosphere. These particles encourage the formation of more, smaller water droplets in clouds, which increases their reflectivity. As a result, more sunlight is reflected back into space, potentially cooling the planet. While it offers a possible way to mitigate climate change effects, it also raises concerns about unintended environmental impacts and ethical considerations.
