Another stupid Greenie prophecy from Australia: "The Reef will never be the same again"
This is just straight Greenie propaganda, with no regard to all the facts. The GBR has had some bleaching events lately but it is nothing compared to Bikini Atoll, which had a thermonuclear device exploded above it. And Bikini coral is thriving again. If coral on Bikini can survive that, why should not the GBR survive infinitely lesser stressors?
And attributing the isolated bleaching to global warming is just assertion. They offer no evidence for it. The best evidence is that it is due to sea-level changes, not ocean warming.
It does seem that the 2015/2016 summer bleaching was repeated in summer this year (2016/2017). Since water levels change only slowly, that is to be expected.
And note that, while they are busily attributing the bleaching to global warming, they give not a single number for either the global water temperature or the North Queensland water temperature.
So let me supply some numbers: NASA/GISS Tell us that the global December 2016 temperature (mid-summer) was .77, which was DOWN on December 2015 (1.10)and even slightly down on 2014 (.79). So in the period at issue, there was NO global warming. So the guys below are lying through their teeth. They say that the bleaching was caused by global warming but there WAS no global warming in the period concerned.
And they also don't give numbers for sea levels in the area. They are zealously hiding the real cause of the bleaching
THE biggest jewel in Australia’s tourism crown will never look the same again — and to fix it, Australia needs a worldwide hand.
Made up of 3000 individual reef systems, the Great Barrier Reef is the world’s largest living organism. It is home to 300 species of coral and a vast array of fish, molluscs, starfish and other marine life.
The Reef also supports a $6 billion tourism industry that provides employment for 69,000 people — all of which is in strife if environmental degradation causes significant, widespread harm.
Already back-to-back coral bleaching episodes have taken their toll, wiping out nearly 600km of coral mostly in the far north.
Caused by rising ocean temperatures that kill food-generating algal organisms inside the coral, no one can say with any confidence that bleaching will not become an annual event.
Even more worrying, scientific data suggests a further two-degree increase in ocean temperatures would wipe-out most of the hard corals.
The man in charge of the Reef Recovery program at the Great Barrier Reef Marine Park Authority, Dr Mark Read, concedes it will never look the same again.
Although some corals will build up a resilience to warmer temperatures, a number of species are facing extinction.
“I think it’s going to end being a real mosaic,” said Dr Read.
“Some parts of the Reef are going to look more classic — hard coral-dominated — that we’re familiar with while other parts will be less dominated by hard coral and more dominated by soft coral and algae.”
While natural habitats are destined to change over time, Dr Read says in the Reef’s case, mankind has contributed to the “current accelerated period of heating” causing coral bleaching.
“We are talking about a global phenomenon,” Dr Read said.
“(Coral bleaching) is happening all around the world where you have hard coral. The Great Barrier Reef has been hit particularly hard, so it’s front of mind.”
Among the strategies being used by his team to aid in the Reef’s recovery, are ensuring activities in the area do not adversely impact the delicate marine environment; tackling the insidious Crown of Thorns starfish; improving water quality and reducing the volume of debris that finds its way into the massive water park.
Together those initiatives will make a difference but Dr Read admits they won’t prevent more episodes of coral bleaching.
“In terms of dealing with the warming per se, that is something that needs to be tackled at that global level,” he said.
“What we do, and what we can do is reduce as many of the direct pressures on the Reef to enhance its capacity to bounce back.”
Those who make a living from the Reef are watching the situation with some trepidation.
Despite chalking up their best tourism season since 1997 in 2016, long-term operators know the back-to-back coral bleaching events that have received global coverage will eventually take their toll.
