What happened

Many of the Caribbean's most important reefs are going unprotected Gaby Clark Scientific Editor Robert Egan Associate Editor Living by the sea in the tropics means being exposed to some of nature's most powerful forces.

Why it matters

Hurricanes can bring storm surges, flooding and destructive waves that threaten homes, infrastructure and livelihoods.

Common ground

For many communities, coral reefs are a natural first line of defense against these storms.

Claim 4: “Without them, studies suggest, the damage would double.”

SINGLE SOURCE

The specific claim that damage would 'double' without reefs appears in one source; however, the provided evidence for claim 2 contains irrelevant OnlyFans links, and the relevant evidence for claim 1 mentions a decline of 1 meter would 'more than double' damages, which is a specific condition rather than a general statement about total reef loss.
