Bleaching of the Great Barrier Reef could happen every two years, report finds

Another Greenie prophecy that is bound to look absurd in the near future!  Greenies never tire of making scary prophecies even though they have yet to get one right.

We read: "The Climate Council is Australia’s leading climate change communications organisation".  That should tell you that they will never find that all is well.  People who believe in climate change never do.  Couple that with dissenting scientists like Peter Ridd getting fired and you can be sure that the "report" below is just propaganda based on cherry-picking and exaggeration.

You can tell it is propaganda by their maniacal insistence that only global temperature control will be of any benefit to the reef. They are in the grip of a reality-denying cult


THE Great Barrier Reef could be hit with catastrophic bleaching every two years unless more is done to limit climate change.

A new report from the Climate Council reveals coral bleaching is now happening on average every six years, compared to once every 27 years back in the 1980s.

Based on current rising greenhouse gas levels, bleaching will happen every two years by 2034.

In the report released today Lethal Consequences: Climate Change Impacts on the Great Barrier Reef, the Climate Council says the current rate of bleaching is not sustainable because it will continuously set back recovery of the reef.

At the same time, the reef will also need to deal with other threats caused by climate change — such as ocean acidification and tropical cyclones.

The report found average coral cover in the northern section of the reef is at its lowest point on record, and coral cover in the central section of the reef declined from 22 per cent in

2016 to 14 per cent in 2018, largely due to the 2017 bleaching event.

It said the damage to the reef may be irreversible and it has already resulted in a drop in the diversity of fish species and in the number of juvenile fish settling on the reef.

"Intensifying marine heatwaves around the world are now occurring more often, lasting longer and are more intense than ever before," Climate Councillor and ecologist Professor Lesley Hughes said.

Professor Hughes said the bleaching events in 2016 and 2017 resulted in mass coral mortality, with the 2016 bleaching event at least 175 times more likely to occur due to intensifying climate change.

"Unless drastic action is taken, extreme coral bleaching will be the new normal by the 2030s. We will see extreme ocean temperatures, similar to those that led to these bleaching events possibly occurring every two years, which will effectively sign the death certificate for the world’s largest natural living wonder that is the Great Barrier Reef," she said.

The report makes clear that doing things like improving water quality are not the solution.

It says that unless "deep cuts in greenhouse gas emissions are made as a matter of urgency — the reef stands little chance no matter what measures are taken to enhance its resilience".

In particular, global warming must be limited to 1.5 degrees above pre-industrial levels.

"A 2C rise in average global temperature will almost certainly mean the collapse of warm water tropical reefs around the world," the report states.

"The decisions and actions that we take today to reduce greenhouse pollution will have a critical effect on the long-term survival of the iconic Great Barrier Reef."

Climate Council acting chief executive officer Dr Martin Rice said the future of coral reefs around the world depended on nations including Australia doing their part to tackle climate change.
