Response of Hawaiian and other Indo-Pacific reef corals to elevated temperature
The Hū Honua plant is discharging warm water into the ocean without cooling, which will have detrimental impacts on sensitive reef systems in Hāmākua.
"Bleaching can be induced by short-term exposure (i.e. 1–2 days) at temperature elevations of 3°C to 4°C above normal summer ambient or by long-term exposure (i.e. several weeks) at elevations of 1°C to 2°C. Corals in both tropical and subtropical locations live at temperatures close to their lethal limits during the summer months. Temperature elevations above summer ambient, but still below the bleaching threshold, can impair growth and reproduction."
