The Five Deaths of The Great Barrier Reef

  The Five Deaths of The Great Barrier Reef One of the world's wonders is more resilient than you'd imagine.Using data collected from 16 points across the reef over a period of 10 years, the study found what the scientists call five separate "death events" from which the Reef bounced back. However, the latest man-made conditions are unique in the reef's history.

It didn't take long for questions to be raised about the decision to give $444 million in funding to the Great Barrier Reef Foundation, a small charity with a revenue of only $8 million in 2016.

The funding will be split between improving water quality, supporting reef restoration science, increasing crown-of-thorns starfish control, community engagement and reef monitoring.

But there is no acknowledgement of what scientists argue is the biggest threat facing the reef: climate change.

Geoengineering: The quick, and potentially catastrophic, fix for climate change

  Geoengineering: The quick, and potentially catastrophic, fix for climate change Geoengineering solutions to climate change sound like magic, but a leading proponent says most people working on climate change dare not speak its name.Pumping aerosols into the upper atmosphere to make clouds more reflective, for example. Or fertilizing oceans with iron to promote the growth of plankton and algae so they consume more carbon dioxide.

Without climate action, can this package actually do anything to help the reef?

The answer is no, according to many involved in reef research, management and conservation, including University of Queensland coral biologist Sophie Dove.

"Unless we mitigate the CO2, a lot of the other solutions such as cleaning the water and removing crown of thorns are somewhat immaterial," Dr Dove said.

"All of those things can assist in helping any coral reefs that remain to survive and prosper in the future — but without climate mitigation, I think that's an issue."

Local reef actions must be met halfway

While the funding is a step forward for addressing local pressures on the reef like water quality, it must go hand in hand with national and global emissions reductions, according to Russell Reichelt from the Great Barrier Reef Marine Park Authority (GBRMPA).

Since the referral, the Turnbull government has announced its $ 500 m rescue package for the reef in this month’ s budget, including 1m to deal with water quality. Budget earmarks $ 500 m to mitigate Great Barrier Reef climate change .

"We're very clear that it is absolutely critical to achieve action globally on climate change, but we're focused on what we can do as the Marine Park Authority in the local region," he said.

The funding was not designed to work on its own, said Dr Reichelt, who chairs the GBRMPA.

"The real solution in the long run is to address rising greenhouse gas concentrations in our atmosphere," he said.

"But we're still left with things that will happen inevitably now, because of the amount of greenhouse gases already in the atmosphere. So there was never a greater imperative that we look for ways to relieve local pressures."

However, some scientists have expressed concern that the funding is targeting some local measures that have not yet been proven effective.

Research fellow Jon Brodie from the ARC Centre of Excellence for Coral Reef Studies wrote in The Conversation that "one concern with the package is that it seems to give greatest weight to the strategies that are already being tried — and which have so far fallen a long way short of success".

Reef already changed by warming

Across the entire Great Barrier Reef 30 per cent of corals died after the 2016 bleaching event. In the northern third of the reef, where up to 50 per cent of shallow water corals were lost, some corals actually "cooked" because the underwater heatwave was so severe.

The government is avoiding dealing with the root cause of this, which is climate change, said Great Barrier Reef campaigner Imogen Zeethoven from the Australian Marine Conservation Society.

"I wake up at night thinking, what will it take for this Government to respond effectively, if losing 50 per cent of the shallow water corals on the reef isn't enough?" she said.

"They can invest $500 million over six years, but if they do nothing about climate change then it will all be wasted in the end."

Coral ecosystems have already been radically transformed by climate change.

The loss of corals due to the 2016 bleaching has forced some northern reefs to transition to new compositions of corals with less diversity — dominated by slow-growing species with more simple physical structures.

And scientists have already documented changes in reef fish diversity as a result of the coral loss.

New funding is still critical

Echoing these sentiments, CEO of the Australian Institute of Marine Science Paul Hardisty said the $500 million was a good start, but emissions also needed to be addressed.

"On the business-as-usual trajectory … in a few decades there won't be any reefs, or at least reefs as we know them today," Dr Hardisty said.

"If you don't get greenhouse gas emissions under control then no amount of money is any use."

But Dr Hardisty said that didn't mean we should stop funding other local reef protection measures.

"We're past the point where we can say that getting emissions under control will be enough," he said.

"To have healthy reefs that provide trillions of dollars in ecosystem services to humans every year, then you've got to do both, there isn't another option."

By relieving other pressures on the reef such as poor water quality and crown-of-thorns starfish, the reefs of the future will have a better shot at surviving — no matter that form they take.

So where is the simultaneous climate action?

Spending on climate issues was cut in the 2018 budget from $3 billion to $1.6 billion in 2019, and it will be reduced further to $1.25 billion by 2022.

On top of that, the National Energy Guarantee (NEG) has an emissions reduction target of 26 to 28 per cent by 2030, which reef campaigner Imogen Zeethoven said was insufficient.

"A 26 per cent reduction, as proposed by the NEG, matched by all the countries in the world would result in all coral reefs in the world dying," Ms Zeethoven said.

"They need to dramatically upscale their emissions reduction target to match the funding investment that they're putting into the reef."

Dr Reichelt said that advocating for both global and local solutions for the reef was like walking a tightrope.

He said it was a balance between "making sure people understand the underlying cause and the need for global action, as well as not giving up on the reef locally".

"If the reef does survive until the end of the century we'll have a better, more diverse coral reef if we take all these local actions now," he said.
