Washington (AFP) - The world is currently experiencing its second major coral bleaching event in 10 years, with reef systems from Australia to Florida teetering on the brink of disaster following months of record-breaking ocean heat, a US agency announced Monday. The consequences of coral bleaching are far-reaching, affecting not only the health of oceans but also the livelihoods of people, food security, and local economies. Severe or prolonged heat stress leads to corals dying off, but there is hope for recovery if temperatures drop and other stressors such as overfishing and pollution are...

Miami (AFP) - Coral reefs off the Florida Keys islands are struggling to recover from last summer's record-breaking heat wave, new data showed Thursday, in another sign of the devastating impacts of human-caused climate change. The state's southern waters experienced hot tub-like conditions with temperatures in July briefly topping 100 degrees Fahrenheit (37.8C) in Manatee Bay. Coral, marine invertebrates made up of individual animals called polyps, have a symbiotic relationship with the algae that live inside their tissue and provide their primary source of food. When the water is too warm, ...

Washington (AFP) - Overfishing is driving coral reef sharks towards extinction, according to a global study out Thursday that signals far greater peril to the marine predators than previously thought. That matters to humans because the species act as managers of their marine ecosystems, maintaining delicately balanced food webs on which hundreds of millions of people rely. The research, published in the journal Science, is the result of the Global FinPrint project, which collected more than 22,000 hours of video footage from reefs across Africa, the Middle East, Asia, Australasia and the Ameri...

Miami (AFP) - A bit of coral shimmers like gold in a US lab as part of urgent work to help the species protect itself from climate change, an effort even skeptical experts see as sadly justifiable. Researchers in Florida are aiming to determine whether coral can be saved from rising water temperatures and acidification by transplanting stem cells from resistant varieties to those more vulnerable to climate impacts. In other words, global warming worries have reached a point that scientists are trying to tweak some organisms' genetics so that they might survive. "Reefs are dying at an alarming ...
