(Caleb Jones/AP) From Banana Boat to Coppertone, major sunscreen brands may soon have to revamp their products or stop selling them in Hawaii. State lawmakers passed legislation Tuesday that would ban skin-care companies from selling and distributing sunscreens on the islands that contain two chemicals deemed damaging to coral reefs. If Gov. David Ige (D) signs the bill, it would make Hawaii the first state to enact legislation designed … [Read more...] about Hawaii might be about to ban your favorite sunscreen to protect its coral reefs
Uma Sharma, provided by Published 10:00 am, Monday, April 23, 2018 We're currently facing the worst bleaching of coral reefs ever known in history, but what would happen if all the coral reefs died off? We've already lost 50% of the world's coral, and we're at risk of losing even more. If the world lost all its coral reefs, the results would be dire. Following is a transcript of the video. What would happen if all the coral reefs died off? Coral reefs are filled with colorful ocean life. But they're in danger of dying off. The planet has already lost 50% of its coral in the last 30 years. If the rest go, the consequences would be dire.

Deron Burkepile, University of California, Santa Barbara Updated 3:02 pm, Friday, April 6, 2018 (The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts.) Deron Burkepile, University of California, Santa Barbara and Mark C. Ladd, University of California, Santa Barbara (THE CONVERSATION) These are bleak times for coral reefs. Warming ocean waters, disease outbreaks, pollution, sedimentation, careless scuba divers, destructive fishing practices, and a host of other global and local stressors are decimating coral populations at unprecedented rates. If there is any silver lining to these events, it may be that many of the disturbances killing corals are acute: They occur just for a short period of time and then disappear, potentially allowing corals to recover before the next disturbance. But as stressors become more and more frequent, humans may have to help foster corals’ recovery. Many organizations are working … [Read more...] about Coral reefs are in crisis – but scientists are finding effective ways to restore them
Get the Mach newsletter. SUBSCRIBE Like other coral reefs around the world, Australia’s Great Barrier Reef is facing big threats from climate change — such as warmer and more acidic seawater and increased ultraviolet (UV) radiation from the sun. Last year experts said large sections of the reef were essentially dead, bleached into oblivion. But scientists Down Under have come up with a sunscreen of sorts that they say could help protect the reef during heat waves. It’s an ultra-thin layer of calcium carbonate — the same material naturally found in coral skeletons — that could be applied to the water’s surface above the reef. “Our aim is to give the coral time to adjust to the changed conditions of high temperature and doses of UV light so that the coral forms different chemical structures that can survive,” Dr. David Solomon, a professor of chemical and biomolecular engineering at the University of Melbourne and a senior advisor to … [Read more...] about Can this ultra-thin ‘sunscreen’ save the world’s largest coral reef?
A coral reef in the Red Sea that can resist rising water temperatures could be the key to saving dying reefs in others parts of the world, a team of scientists from Switzerland and Israel has discovered. In a study conducted by Lausanne University, Lausanne federal technology institute EPFL and scientists at two institutions in Israel, corals in the Gulf of Aqaba, in the Red Sea, were found to be resistant to the effects of global warming and ocean acidification, EPFL said in a statement as the results were published in the Royal Society Open Science journal on Wednesday. Over a six-week period researchers exposed the corals to higher water temperatures and acidification to mimic the summer conditions of a future ocean in that region if sea temperatures continue to rise at their current rate. Most corals put under the same stresses “would probably bleach and have a high degree of mortality,” said EPFL scientist Thomas Krueger. However with the Gulf of … [Read more...] about Swiss scientists help discover coral reef that could survive global warming
