Ocean acidification and associated declines in aragonite saturation state  decrease rates of calcification by corals and other calcifying reef organisms , reduce coral settlement  and increase bioerosion and dissolution of reef substrates  . Warming can exacerbate the coral response to ocean acidification  and accelerate the decrease in coral skeletal density . In addition, reefs with lower coral cover and a higher proportion of slow-growing species, because of bleaching, are more sensitive to acidification . However, experimental evidence suggests that coral responses to ocean acidification are species specific  . Evidence from
