Great Barrier Reef: 93% of reefs hit by coral bleaching
2016-04-19 22:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Almost 93% of reefs on the Great Barrier Reef have been hit by coral bleaching, according to a comprehensive survey revealing the full extent of the devastation caused by abnormally warm ocean temperatures sweeping the globe. There have only been three mass bleaching events recorded on the reef , and all of them have happened since 1998. Scientists say this episode is the worst theyve ever seen. The world is in the midst of a global bleaching event, which is a result of a pulse of warm water...
Why dead coral reefs could mark beginning of dangerous climate change

Post: The island of Kiritimati is one of the worlds most remote places -- one of several dozen atolls making up the tiny island nation of Kiribati, a speck in the Pacific Ocean more than a thousand miles south of Hawaii. But, isolated as it is, news of its devastated coral is turning heads around the world. A recent expedition has revealed that the reefs around Kiritimati have suffered a catastrophic mass die-off -- an event that epitomizes what may be an ugly truth about the ability of coral reefs around...

Scientists express alarm at 'devastating' impact of climate change on coral reefs
2016-04-10 18:10:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Scientists have expressed alarm at the devastating impact of climate change on the world's coral reefs. More than a third of Earths reefs are now under threat due a process known as bleaching, in what could be the worst crisis ever to hit these vital ecosystems. Bleaching, where the symbiotic relationship between algae and small animals called polyps breaks down, can occur under heat stress and has been linked to multiple weather events including the latest severe El Nio phenomenon. The...

Global warming, El Nino leave 36 per cent of coral reefs on death watch

CBC: The coral on the sea floor around the Pacific island of Kiritimati looked like a boneyard in November stark, white and lifeless. But there was still some hope. This month, color returned with fuzzy reds and browns but that's not good news. Algae has overtaken the lifeless coral on what had been some of the most pristine coral reefs on the planet, said University of Victoria coral reef scientist Julia Baum after dozens of dives in the past week. Maybe 5 percent will survive, she estimated....
Coral Reefs Bounce Back Despite Warming Of Oceans

Inquisitr: Coral reefs have managed to bounce back, despite being under constant threat of extinction. However, marine scientists caution these fragile ecosystems are still being threatened by global warming, pollution and human activity. The discovery of a large number of coral reefs in excellent health has been quite a joyous occasion for the researchers who routinely deal with ominous news like mass die-offs, worldwide bleaching events, oil spills, and such other calamities which have been pushing the...
