stratospheric injection

Stratospheric injection involves releasing substances, like aerosols or reflective particles, into the Earth's stratosphere (about 10 to 50 kilometers above ground). This technique aims to reflect some sunlight back into space, thereby temporarily reducing global temperatures and counteracting climate change. It is considered a form of geoengineering. The process mimics natural volcanic eruptions, which can cool the planet by dispersing particles that block sunlight. However, it carries environmental and ethical uncertainties, such as potential changes in weather patterns and the need for ongoing intervention, making it a complex and controversial approach to managing global warming.
