Researchers have studied the hard skeletons of coral reefs to better predict their survival. Vulnerable to ocean acidification caused by global warming, corals are among the most threatened underwater species. Corals that inhabit the ocean floor are particularly vulnerable to global warming. They are particularly vulnerable to ocean acidification, brought about by atmospheric CO2 emissions generated by human activity, which increases the ocean temperature and accelerates coral bleaching. Researchers at the University of Wisconsin-Madison (USA) have attempted to predict the resilience of coral …
