Climate change occurs because greenhouse gases trap the sun's energy in our atmosphere, causing that energy to warm the planet. A radical and controversial plan that would artificially modify the Earth's atmosphere to cool the planet is starting to gain traction
Solar geoengineering seeks to reflect a small fraction of sunlight back into space, or increase the amount of solar radiation that escapes back into space, to cool the planet. In contrast to carbon geoengineering, solar geoengineering does not address the root cause of climate change. It instead aims to break the link from concentrations to temperatures, thereby reducing some climate damages.
