Half Australia's Great Barrier Reef coral 'dead or dying': scientists

2016-04-20 08:13:00| Climate Ark Climate Change & Global Warming Newsfeed

Reuters: SYDNEY Australian scientists said on Wednesday that just seven percent of the Great Barrier Reef, which attracts around A$5 billion ($3.90 billion) in tourism every year, has been untouched by mass bleaching that is likely to destroy half the coral. Bleaching occurs when the water is too warm, forcing coral to expel living algae and causing it to calcify and turn white. Mildly bleached coral can recover if the temperature drops, otherwise it may die. Although the impact has been exacerbated...

Quadrangle: Surveys reveal 93 pct of Great Barrier Reef affected by bleaching "I'm inherently an optimist, but I think we have a rapidly narrowing window of opportunity to save the Great Barrier Reef", Prof Hughes said. A new survey has confirmed pretty much every environmentalist's worst fears, revealing that 93 percent of Australia's Great Barrier Reef has already been damaged by coral bleaching. Scientists say the latest bleaching event - the third since 1998 - is being driven by abnormally high...

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...

Warming Threatens the Great Barrier Reef Even More Than We Thought

2016-04-14 20:25:00| Climate Ark Climate Change & Global Warming Newsfeed

National Geographic: The iconic reef depends on protective pulses of warm water to boost its heat tolerance. Climate change may eliminate these "practice runs." This panoramic image reveals coral bleaching at Lizard Island on the Great Barrier Reef in March 2016. The current bleaching is the worst the reef has experienced in its history. When waters get too hot, corals stress out and turn a ghostly white, and to survive, they must complete a marathon-like feat of endurance. Now, for the first time, new research...
