Part 3/9:
Solar geoengineering, often referred to as climate intervention technology, involves reflecting a tiny fraction of sunlight to counteract some effects of increased greenhouse gases. This concept finds inspiration in natural phenomena: during volcanic eruptions, ash particles reflect sunlight, leading to temporary cooling effects.
The leading method proposed involves dispersing aerosol particles—such as calcium carbonate—into the upper atmosphere, creating a reflective shield that diminishes incoming solar radiation and cools global temperatures.
