by Marlowe HOOD Agence France-Presse PARIS, France (AFP) – Dynamite fishing and pollution — but mostly global warming — wiped out 14 percent of the world’s coral reefs from 2009 to 2018, leaving graveyards of bleached skeletons where vibrant ecosystems once thrived, according to the largest ever survey of coral health. Hardest hit were corals in South Asia and the Pacific, around the Arabian Peninsula, and off the coast of Australia, more than 300 scientists […]
BRISBANE, Australia (AFP) — Australia’s Great Barrier Reef has suffered its most widespread coral bleaching on record, scientists said Tuesday in a dire warning about the threat posed by climate change to the world’s largest living organism. James Cook University professor Terry Hughes said a comprehensive survey last month found record sea temperatures had caused the third mass bleaching of the 2,300-kilometre (1,400-mile) reef system in just five years. Bleaching occurs when healthy corals become […]
SYDNEY, Australia (AFP) — Corals on Australia’s Great Barrier Reef that survived bleaching from rising sea temperatures were more resistant to another bout of hot conditions the following year, scientists said Tuesday, a “silver lining” for the embattled ecosystem. The 2,300-kilometre (1,400-mile) long UNESCO World Heritage-listed reef off Australia’s northeastern coast was hit by back-to-back bleaching in 2016 and 2017. Bleaching occurs when abnormal environmental conditions, such as warmer sea temperatures, cause corals to expel […]

(AFP) — Australia’s Great Barrier Reef, under severe stress in a warmer, more acidic ocean, has returned from near-extinction five times in the past 30,000 years, researchers said Monday. And while this suggests the reef may be more resilient than once thought, it has likely never faced an onslaught quite as severe as today, they added. “I have grave concerns about the ability of the reef in its current form to survive the pace of […]
SYDNEY, Australia (AFP) — Coral bleached for two consecutive years at Australia’s Great Barrier Reef has “zero prospect” of recovery, scientists warned Monday, as they confirmed the site has again been hit by warming sea temperatures. Researchers said last month they were detecting another round of mass bleaching this year after a severe event in 2016, and their fears were confirmed after aerial surveys of the entire 2,300-kilometre (1,400-mile) long bio-diverse reef. Last year, the […]
PARIS, France (AFP) — Australia’s Great Barrier Reef may never recover from last year’s warming-driven coral bleaching, said a study Wednesday that called for urgent action in the face of ineffective conservation efforts. Record-high temperatures in 2015 and 2016 drove an unprecedented bleaching episode, which occurs when stressed corals expel the algae that live in their tissue and provide them with food. Bleached coral is more susceptible to disease, and without sufficient time to recover […]
by Glenda KWEK Agence France Presse SYDNEY, Australia (AFP) — Australia’s Great Barrier Reef is experiencing an unprecedented second straight year of mass coral bleaching, scientists said Friday, warning many species would struggle to fully recover. The 2,300-kilometre (1,400-mile) reef suffered its most severe bleaching on record last year due to warming sea temperatures during March and April. Bleaching is once again occurring, the government’s Great Barrier Reef Marine Park Authority said after an aerial […]
GENEVA, Switzerland (AFP) – Coral reefs in the Maldives are under severe stress after suffering mass bleaching this year as sea temperatures soared, a top conservationist body warned Monday. Around 60 percent of Maldives’ coral colonies have been bleached, with the figure reaching 90 percent in some areas, the International Union for Conservation of Nature (IUCN) said in a statement. It cited data from a survey it carried out with the Maldives Marine Research Center […]
