Coral reef experts have grown wary of summer months because if temperatures get too hot in July or August, whole reefs can get wiped out. That is lowering the pH of the water, or making it more acidic, which can make it harder for reef-building organisms to construct their hard skeletons.

They’re also visual wonders that generate billions of dollars in tourism revenue annually for countries that neighbor them. “What caused the August 2016 die-off was strong water column stratification, and stratification is exactly what doesn’t happen during a hurricane. }); Coral reefs are also threatened by industrial pollution, invasive species, overfishing, plastic pollution, and ocean acidification, which is when the oceans absorb too much carbon dioxide from fossil fuel emissions and acidify. As a result, over 50 percent of the world’s coral reefs have died in the last 30 years and up to 90 percent may die within the next century—very few pristine coral reefs still exist. For many reefs, this was the first time on record that they had experienced bleaching in two consecutive years. People who want to learn about and take action on the world’s biggest challenges. Bleaching occurs when warm ocean water stresses corals to the point that they expel the tiny algae, known as zooxanthellae, that normally live inside their tissues. }; In Hawaii, the Kingman Reef is suffering from invasive algae species that are blotting out various forms of life and turning corals a dark green or black. That warming trend is expected to continue through the year, leading to what may be the longest global coral bleaching event in history. Bleaching events have accelerated in recent years and scientists predict that nearly all coral reefs could be destroyed by this phenomenon by 2050. const appConfig = { In an interview with Yale Environment 360, she assesses the state of the world’s corals and highlights conservation projects that offer hope of saving these irreplaceable ecosystems. They then fixed underwater loudspeakers to the center of the patches, angling them upward to ensure the sound was distributed evenly in all directions. In the absence of the zooxanthellae, corals start dying and so does the reef formed by the coral. trackAnonymousUsers: true Coral reefs are vital for a healthy ecosystem.
