Scientific Assessment of Ozone Depletion

The scientific assessment of ozone depletion evaluates how the ozone layer—the Earth's protective shield—has been thinning due to human-made chemicals like chlorofluorocarbons (CFCs). Experts analyze data from satellites, ground stations, and ice cores to understand ozone levels and the impact of these chemicals. This assessment helps measure the extent of ozone loss, identify its causes, and track changes over time. The goal is to inform policies that protect the ozone layer, preventing increased UV radiation from reaching the Earth's surface, which can harm living organisms and ecosystems.
