Cauliflower coral, a bushy species in the Hawaiian Islands that has been devastated by ocean warming triggered by human-caused climate change, could soon get federal protection. The National Marine Fisheries Service Wednesday announced that listing the species may be warranted under the Endangered Species Act, based on a petition from the Center for Biological Diversity.
Conservative lawmaker Scott Morrison has forced out Malcolm Turnbull as Australian prime minister, the third time the country's leader has sunk over climate policy in the past decade, and the seventh since 1997, according to Australia's ABC News.
An internal Liberal party row started when Turnbull proposed modest emissions targets for the country's energy sector. He dropped the plans Monday after pressure from the party's right-wing faction, but that led to a narrowly defeated leadership challenge from Peter Dutton on Tuesday, then a final ousting from Morrison on Friday.
The French overseas territory of New Caledonia announced Tuesday the highest possible levels of protection for some of the world's last unspoiled coral reefs.
All types of extraction, including commercial and industrial fishing, has been banned in the Chesterfield, Bellona, Entrecasteaux, Pétrie and Astrolabe coral ecosystems, according to a Tuesday press release from the World Wildlife Fund (WWF), which has long pushed the reefs' protection.

Hawaii's knobby finger coral careened toward extinction in 2015. The species was so rare that scientists could only find a few fragments in the wild, scattered across the seabed of Oahu's Kaneohe Bay.
It might have been a familiar story. Vanishing species like Southern Resident orcas and North Atlantic right whales pile up in the news. Outlooks are especially bleak for corals. Rising ocean temperatures cause bleaching, which has killed 30 to 40 percent of reefs worldwide in recent years. But the knobby finger coral's story didn't go that way, thanks to computer forecasting: science's crystal ball.

In May 2016, technical divers descended 200 feet to Benham Bank, the shallowest portion of a huge underwater plateau off the Philippines' northeast tip. As they neared the bottom, an otherworldly landscape emerged from the dim cobalt blue.
Plates of coral grew one atop the other like china at a yard sale, dotted with sea fans and sprigs of algae. Coral columns encrusted in yellow, orange and pink coralline algae looked as though they'd been splashed with rainbow paint. Colonies thrived as far as the eye could see.
The Great Barrier Reef—Australia's remarkable but imperiled natural wonder—is under risk of repeat coral bleaching events unless greenhouse gas emissions are slashed, Australia's Climate Council warned Thursday.
The new report, Lethal Consequences: Climate Change Impacts on the Great Barrier Reef, determined that by 2034, the extreme ocean temperatures that led to the mass bleaching events of 2016 and 2017 may occur every two years if emissions continue on current trends.

Famous for its turquoise waters and spectacularly diverse animal and plant life, the Maldives also bears the unwelcome distinction of being the country most vulnerable to rising sea levels. The island chain in the Indian Ocean is the flattest nation on earth, with most of its land lying less than five feet above average sea level―and large areas in imminent danger of flooding.
