Buco nell’ozono: si è aperto 30 anni prima e i CFC non c’entravano

Il buco nell'ozono ha trent'anni in più di quanto credevamo. E ad aprirlo, prima dei CFC, fu un altro veleno industriale dimenticato.

A dramatic split-view scientific illustration showing Earth's atmosphere in cross-section: on one side, the familiar Antarctic ozone hole depicted in deep ultraviolet blues and purples as seen from space; on the other side, the tropical stratosphere above the equator circa 1957, with faint chemical molecular structures of carbon tetrachloride dissolving into the upper atmosphere. In the foreground, a mid-century dry cleaning shop with steaming garments and industrial solvents evaporating into the air, the invisible chemical plume rising upward through layers of atmosphere toward a thinning ozone layer shown as a translucent green band. The overall palette blends vintage sepia tones of the 1950s with cold scientific satellite imagery blues and purples, conveying the unseen decades of atmospheric damage predating official discovery. Editorial, photorealistic style with scientific visualization elements.
