## Executive Summary
New scientific findings suggest ozone layer depletion began decades before the discovery of the ozone hole and was driven by substances other than CFCs.

## Intelligence Brief
Recent research indicates that ozone loss occurred prior to the widespread use of chlorofluorocarbons (CFCs). This suggests the damage to the ozone layer started much earlier than previously understood.


Coverage from Phys.org, Ars Technica, Gizmodo, and heise online emphasizes that the earliest causes of the ozone hole were not CFCs. The reports highlight a shift in the scientific understanding of the timeline regarding ozone depletion.


Future developments depend on the identification of the specific substances responsible for the early damage, as coverage indicates the depletion was caused by other substances.

## Verified Facts & Key Claims
### Were CFCs the primary cause of the earliest ozone loss?
According to coverage from Gizmodo and Ars Technica, the earliest cause of the ozone hole was not CFCs.

### When did ozone depletion begin?
Phys.org reports that scientists found ozone depletion began decades before the discovery of the ozone hole.

### What caused the early ozone layer damage?
heise online states that the damage began earlier and was caused by other substances.

## Key People, Organizations & Locations
Ozone, Earliest Cause, CFCs After All
