EILAT, Israel, Sept 24, 2023 (AFP) – The Red Sea’s spectacular coral reefs face a new threat, marine biologists warn — the mass death of sea urchins that may be caused by a mystery disease. Because the long-spined creatures feed on algae that can suffocate corals, their die-off could “destroy our entire coral reef ecosystem”, warned scientist Lisa-Maria Schmidt. In Israel’s Red Sea resort of Eilat, which borders Jordan and Egypt, Schmidt recalled the moment […]
by Marlowe HOOD Agence France-Presse PARIS, France (AFP) – Coral reefs that anchor a quarter of marine wildlife and the livelihoods of more than half-a-billion people will most likely be wiped out even if global warming is capped within Paris climate goals, researchers said Tuesday. An average increase of 1.5 degrees Celsius above pre-industrial levels would see more than 99 percent of the world’s coral reefs unable to recover from ever more frequent marine heat […]
by Kelly MACNAMARA Agence France-Presse PARIS, France (AFP) – Scientists have discovered a vast reef of “pristine” rose-shaped corals apparently unharmed by climate change in deep water off the coast of Tahiti, UNESCO announced Thursday. Mapping approximately three kilometres (two miles) long and up to 65 metres (213 feet) wide, UNESCO said it was “one of the most extensive healthy coral reefs on record”. The UN heritage agency said it was “highly unusual” to find […]
by Nick Perry Agence France-Presse NAIROBI, Kenya (AFP) – Rising sea temperatures and overfishing threaten coral reefs in the western Indian Ocean with complete collapse in the next 50 years, according to a groundbreaking study of these marine ecosystems. The findings, published in the journal Nature Sustainability on Monday, warned that reefs along the eastern coast of Africa and island nations like Mauritius and Seychelles faced a high risk of extinction unless urgent action was […]
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) — More corals are dying and others are succumbing to disease and predators after the worst-ever bleaching on Australia’s iconic Great Barrier Reef, scientists said Wednesday. A swathe of corals bleached in the northern third of the 2,300-kilometre (1,429-mile) long biodiverse site off the Queensland state coast died after an unprecedented bleaching earlier this year as sea temperatures rose. And researchers who returned to the region to survey the area this month said […]
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 […]
