Caribbean coral spawning shifts signal a measurable climate-driven change
For 19 years, the Mexican Caribbean spawning database has tracked three reef-building corals. Now, measurable shifts appear. *Acropora palmata* near urbanized reefs has lost its synchronized spawning window, a critical bottleneck for fertilization. This loss, compounded by declining coral cover, triggers the Allee Effect, reducing natural reproduction odds. The solution may require human-assisted fertilization to restore this keystone species.

Florida Keys Reef Accretion Diminished by Repeated Bleaching Events
The Florida Keys' reef-accretion potential has fallen from 1.65 millimeters per year in 1996 to net erosion following the 2023 bleaching event, with four thermal-stress episodes driving over 75 percent of the total decline. The 1997-1998 event alone accounted for roughly half of that loss, largely through the collapse of *Acropora palmata*. This is not a distant threat; it is a measurable, documented trajectory.
