By using our site, you acknowledge that you have read and understand our Privacy Policy “The critical habitat protections are fantastic for these corals,” said Miyoko Sakashita, Oceans Director for the environmental nonprofit Center for Biological Diversity. Impacts of the climate crisis include ocean acidification, which hinders the ability of corals to grow, and ocean warming, which causes corals to expel the algae living in their tissues in a phenomenon known as coral bleaching. In a long-awaited move from the Trump administration, the US has proposed critical habitat protections for twelve coral species in the Caribbean and Pacific Ocean. Calcium carbonate is what skeletons are made of—and it dissolves under hot, acidic conditions. ... Chai A. Fishing and land-based pollution have also contributed to the species’ decline. Chronic exposure to the combined impacts of ocean warming and acidification will weaken reefs. University of Erlangen-Nuremberg.

"In addition, more than 110% calcifier cover is needed to keep up with the minimal levels of sea-level rise.". "The combined impact of warming with the acidification of our oceans will see more than the collapse of ecosystems," A/Prof Dove said. ARC Centre of Excellence for Coral Reef Studies. “I don’t like to say that reefs in Florida are on their last legs, but if we don’t increase our efforts to save them soon, they will be,” said Andrew Baker, a marine biologist with the University of Miami who specializes in the impact of climate change on coral reefs. "If CO2 emissions aren't curbed, by the end-of-century a 50% calcifier cover is required to counter the physical erosion they face from storms and wave impacts," she said. The new habitat protections will help regulate local threats to corals like overfishing, pollution, and dredging operations.
