🐢 A healthy coral reef takes most of the force out of a wave before it reaches the shore. A global study across tropical oceans found that reefs reduce wave energy by 97% on average, lowering flood and erosion risk for the coastal communities behind them.
That protection depends on the reef staying alive. As reefs degrade, the buffer weakens and communities face higher costs to defend their coasts in other ways.
Ahead of (9 to 20 November), the message is clear: protecting and restoring reefs is climate adaptation, and it belongs in climate plans from the start, alongside sea walls and other defences.
