Editorial note · April 2026
Western Atlantic reef systems have now been at NOAA bleaching alert level two for seven consecutive months — the longest continuous event on record. Previous events of this duration were followed by permanent coral mortality across 40–70% of affected reef area. Field dispatches from Florida, Belize, and the Bahamas are being published this month.
