Coral reefs that protect Caribbean islands from hurricanes are rapidly declining

Hurricane Beryl, which hit the Caribbean as a Category 4 storm, highlights the crucial role of coral reefs in mitigating storm damage, but these vital ecosystems are disappearing.

Benji Jones reports for Vox.

In short:

• Coral reefs act as natural barriers, reducing wave energy and preventing flooding in Caribbean nations.
• The area of live corals has decreased by 80% in recent decades due to climate change and human activities.
• Without reefs, the flood risk in the Caribbean and the U.S. would increase significantly, endangering thousands more people.

Key quote:

"Without reefs, annual damages would more than double."

— Authors of the 2018 study "The global flood protection savings provided by coral reefs."

Why this matters:

Coral reefs provide essential protection against hurricanes, but their decline due to climate change weakens this natural defense. Rising ocean temperatures, acidification, and human activities are causing unprecedented rates of coral bleaching and degradation. As these reefs disappear, so too does their ability to protect coastal communities from the ravages of hurricanes.
