"Global coral bleaching event that has lasted three YEARS has finally ended - but reefs are still fighting for their lives"

Nonsense all round.  The Indian ocean was not affected so the event was not global.  And it is admitted below that the effect was largely due to El Nino, not anthropogenic global warming.  They say that El Nino and anthropogenic global warming together had an additive effect but -- even conceding that CO2 causes anthropogenic global warming -- there was no CO2 rise in the relevant years so there was clearly NO rise in anthropogenic global warming.  To put it semi-algebraically:  El Nino + 0 = El Nino.

And corals are at their most diverse and abundant in warm tropical waters so the claim that warm waters are bad for them is fundamentally perverse.  In Australia's case a sea-level fall was almost certainly the cause of bleaching in warm tropical water off the Far North Queensland coast

And both the extent of the loss and the difficulty of the recovery have been greatly exaggerated.  Do I need once again to mention the coral reef at Bikini atoll which was once the target of a thermonuclear blast -- but which is now again thriving?

 It's just all baseless assertion below.  Correlation is asserted as causation.  Factors like sea-level fluctuations are almost certainly involved but no attempt is made even to look at that.  One doesn't look to Warmists for a balanced account of anything -- which reveals them as fundamentally unscientific.  A scientific paper will normally look at all the possible causes of an event and evaluate them against one another. Warmists know just one cause for everything, ignore all else and assert it "ad infinitum"


A mass bleaching of coral reefs worldwide has finally ended after three years, U.S. scientists announced Monday.

About three-quarters of the world's delicate coral reefs were damaged or killed by hot water in what scientists say was the largest coral catastrophe.

The National Oceanic and Atmospheric Administration first announced a global bleaching event in May 2014.

It was worse than previous global bleaching events in 1998 and 2010.

The forecast damage doesn't look widespread in the Indian Ocean, so the event loses its global scope.

Bleaching will still be bad in the Caribbean and Pacific, but it'll be less severe than recent years, said NOAA coral reef watch coordinator C. Mark Eakin.

Places like Australia's Great Barrier Reef, northwest Hawaii, Guam and parts of the Caribbean have been hit with back-to-back-to-back destruction, Eakin said.

University of Victoria, British Columbia, coral reef scientist Julia Baum plans to travel to Christmas Island in the Pacific where the coral reefs have looked like ghost towns in recent years.

While conditions are improving, it's too early to celebrate, said Eakin, adding that the world may be at a new normal where reefs are barely able to survive during good conditions.

Eakin said coral have difficulty surviving water already getting warmer by man-made climate change. Extra heating of the water from a natural El Nino nudges coral conditions over the edge.
