Pressures

Of the years 1985 to 2025, 2025 brought the most coral heat stress: averaged over the park, the year's highest Degree Heating Weeks reached 15.5 °C-weeks. NOAA counts 4 °C-weeks as bleaching likely and 8 as severe bleaching and mortality likely.NOAA Coral Reef Watch · Public domain
The 2013 cumulative human impact score (Halpern et al. 2015) averages 1.87 across the park, from 0.01 to 4.23.Halpern et al. 2015 · CC0 1.0
