A long-term study of Hawaiian coral species provided a surprisingly optimistic view of how they might survive warmer and more acidic oceans resulting from climate change.

Study authors, including researchers from the Hawaiʻi Institute of Marine Biology (HIMB) at the University of Hawaiʻi at Mānoa, found that the three coral species studied experienced significant mortality under conditions that simulated ocean temperatures and acidity expected in the future—up to about half of some of the species died. But none of them completely died off—and some actually were thriving by the end of the study.
