Coral Bleaching Has Ravaged Half of Hawaii’s Reefs

SOURCE: Earther DATE: November 8, 2017 SNIP: Last week, scientists reported that half of Hawaii’s coral reefs suffered serious bleaching in 2014 and 2015 as part of an ongoing, three-year global bleaching event that researchers are still trying to get a handle on. Hawaii is home to some of the most spectacular reefs in the U.S., which bring in around $800 million a year in revenue. Around 56 percent of the Big Island’s corals bleached, along with 44 percent on West Maui and 32 percent of the reefs around Oahu according to an Associated Press report. “In the 2030s, 30 to 50 percent of the years will have major bleaching events in Hawaii,” Kuulei Rogers, a scientist at the Hawaii Institute of Marine Biology, told the...

Scientists warn US coral reefs are on course to disappear within decades

SOURCE: The Guardian DATE: May 30, 2017 SNIP: Some of America’s most protected corals have been blighted by bleaching, with scientists warning that US reefs are on course to largely disappear within just a few decades because of global warming. New research has shown that strict conservation measures in Hawaii have not spared corals from a warming ocean in one of its most prized bays, with the National Oceanic and Atmospheric Administration predicting yet more bleaching is likely off Hawaii and Florida this summer. “As scientists we are breathlessly trying to catch up,” said Cobb [Kim Cobb, an oceanographer at Georgia Tech]. “Things started to run away from us around 10 years ago but we were perhaps a little naive in not realizing that.” “This is another data point on the staggering breadth of damage across the global oceans. You can run but you can’t hide from the train wreck that is coming. The recent bleaching has been a brush with death and shows that this fatal stress is upon...
Great Barrier Reef is damaged beyond repair and can no longer be saved, say scientists

Great Barrier Reef is damaged beyond repair and can no longer be saved, say scientists

SOURCE: The Telegraph (not usually a trustworthy source on climate change, so keep that in mind…) DATE: May 29, 2017 SNIP: Scientists have concluded that the Great Barrier Reef can no longer be saved because it is so damaged. The plight of the reef is partly due to the “extraordinary rapidity” of climate change, according to experts. The reef has been severely damaged by the warming of the oceans, and around 95 per cent of it suffers from bleaching, according to scientists who surveyed it in 2016. Experts have said the ecological function of the reef should be maintained as much as possible in coming years, but that the reef itself will not be saved in its current...
Coral reef survival hinges on ‘urgent and rapid’ emissions cuts

Coral reef survival hinges on ‘urgent and rapid’ emissions cuts

SOURCE: CarbonBrief.org DATE: March 15, 2017 SNIP: The future of the Great Barrier Reef – and other reefs around the world – will ultimately depend on how successfully we can limit ocean warming. This is the blunt conclusion of a new study, just published in Nature, which examines the impacts of recent coral bleaching events on Australia’s Great Barrier Reef. The event in 2016, for example, left just 9% of surveyed reefs untouched. The study finds that sea surface temperature is the biggest driver of bleaching, while local efforts to improve water quality or restrict fishing have little impact on limiting its severity. This means that “immediate action to curb future warming” is essential if coral reefs are to survive, the authors...
