At the end of April a $500 million package to help the Great Barrier Reef was announced by the Federal Government.

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.

>>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.<<

Cripes “may have limited impact”. What do your want, unlimited impact? Why not ask for perpetual motion while you’re at it?

They probably want the maximum amount of impact that can be achieved if climate change is reduced as far as it can be.

The point is. Spend the money on reducing climate change and informing the rest of th world to do the same.
No amount of money is going to save the reef.

The point is: saving the reef does not take any money away from reducing climate change.

The point is: the reef cannot be be saved unless climate change is brought under control.

That is my point. Yeah

In those breeding events the reef ejects billions of eggs, might some of those be adapted to cooler or warmer waters or being single cell animals the diversity doesn’t work that way?

The relevance is save the reef for whom?
The ones with the biggest lobby at goverment level. Speak with your spent dollar.

It can if the ambient temperatures are there.

I would imagine that there is genetic variation, because there are male and female gametes, that some would. how much i don’t know.

It does but over a long period of time. Even if mutations have occurred, they are unlikely to be common so most would be disadvantaged. Those with the mutated genes will then breed via natural selection and produce more with the favorable gene, but it would still take time to become wide spread within the population.

it is all possible.

The world has lost roughly half its coral reefs in the last 30 years. Scientists are now scrambling to ensure that at least a fraction of these unique ecosystems survives beyond the next three decades. The health of the planet depends on it: Coral reefs support a quarter of all marine species, as well as half a billion people around the world.

Accordig to acceptable conditions.
