Ocean currents are shifting. Study finds corals could become a thing of the past

India Today  

The world is warming up and the oceans are no different. A new study published in the journal Oxford Open Climate Change indicates that the extensive bleaching and deaths of coral point to a more staggering change - the pattern of ocean currents is shifting. Warm ocean currents carry heat from the tropics towards the poles, helping to moderate climate …

Coral reefs around the world experiencing mass bleaching, scientists say

Al Jazeera  

Scientists warn that many of the world’s reefs may not recover from the intense, prolonged heat stress. Along coastlines from Australia to Kenya to Mexico, many of the world’s colourful coral reefs have turned a ghostly white in what scientists say has amounted to the fourth global bleaching event in the last three decades. At least 54 countries and territories …

NOAA extends coral reef alert scale after extreme coral heat stress

CNN  

CNN — With water temperatures climbing to unprecedented heights, the National Oceanic and Atmospheric Administration has added new levels to its alert system to account for increasingly severe coral bleaching and higher mortality rates. Alert Level 5, the new highest level classified as “near complete mortality,” means “greater than 80 percent of corals in the highlighted area are at risk …

Riffling through the reefs: Can India's coral beds be saved?

Hindustan Times  

Corals are marine invertebrates, which are part of the group anthozoans, the largest class of organisms within the phylum Cnidaria, which also includes jellyfish and anemones. “This loss leads to the bleaching effect and, if prolonged, can cause coral mortality,” said Apte, “however, coral bleaching doesn't immediately result in coral death.” Over the last two decades, the Indian Ocean's sea …

Cuban marine biologist Ariandy Gonzalez emerges uneasy from the sun-speckled Caribbean sea off a remote stretch of Cuba's south coast. The ongoing "Bojeo a Cuba" study is a snapshot in time of the health of Cuba's reef, fish and sea life, the first of its kind across such a large area of the island's waters, said Dr. Fabian Pina, a …

Armed with scrub brushes, young scuba divers took to the waters of Florida’s Alligator Reef in late July to try to help corals struggling to survive 2023’s extraordinary marine heat wave. Normally, I.CARE’s volunteer divers would be transplanting corals to waters off the Florida Keys this time of year, as part of a national effort to restore the Florida Reef. …

Scientists say Florida Keys coral reefs are already bleaching as water temperatures hit record highs

Associated Press  

FORT LAUDERDALE, Fla. — Some Florida Keys coral reefs are losing their color weeks earlier than normal this summer because of record-high water temperatures, meaning they are under stress and their health is potentially endangered, federal scientists said. Surface temperatures around the Keys have been averaging about 91 degrees, well above the normal mid-July average of 85 degrees, said Jacqueline …

The Hindu  

Record temperatures around the world have left animals, including humans, in dire straits. There is more to bleaching, however: most corals are home to a type of algae called zooxanthellae, which give the corals their colours as well as have a symbiotic relationship with them. When the ocean environment changes – for example, if its temperature rises beyond a point, …

News 18  

Some corals can recover from bleaching even in long heatwaves as long as humans don’t interfere, scientists said Tuesday, raising hopes for the endangered underwater ecosystems essential to much marine life. “We found that corals were only able to recover from bleaching while at elevated temperatures if they were not also exposed to other strong local stressors,” Baum said.
