Claim: Great Barrier Reef Set to Disappear Because of Global Warming

Guest essay by Eric Worrall

According to EU Official Virginijus Sinkevičius, Corals which survived the dinosaur killer, the Cretaceous / Paleogene Extinction event, will soon disappear because we have raised atmospheric CO2 a few parts per million.

European Union official sounds alarm over threats to Great Barrier Reef

EU commissioner Virginijus Sinkevičius urges Australia to sign Leaders’ Pledge for Nature that promotes a green recovery from Covid crisis

A senior European Union official has sounded the alarm over the rapid decline of Australia’s Great Barrier Reef while backing calls for all countries to make more ambitious cuts to greenhouse gas emissions.

The EU’s commissioner for environment, oceans and fisheries, Virginijus Sinkevičius, told Guardian Australia he was deeply concerned by the threats facing the Great Barrier Reef. “As long as we do not change our behaviours, things will not improve,” he said.

Sinkevičius hopes Australia will sign up to the 84-country Leaders’ Pledge for Nature – a document that calls for a “green and just” recovery from the Covid-19 crisis and stronger political will to act against the “crises of biodiversity loss and ecosystem degradation and climate change”.

The leaders’ pledge backs the objective of achieving net zero emissions by 2050. That is a target the Australian prime minister, Scott Morrison, has said is his preference, but he has resisted making a formal commitment amid divisions within his government over climate policy.

If this is an April Fools joke its a good one. At worse global warming would push Aussie Coral reefs a little further South, away from the equator. The idea that a tropical warmth loving organism would somehow die off because we’ve made the ocean a little warmer is absurd.

Well surely the ‘dinosaur killer’ made the world colder? whereas at present it is heating up…

and if corals have survived numerous climate change events, they haven’t always survived in the same place.

Ever see the movie “Groundhog Day”? In it Bill Murray is destined to live Feb. 2, Groundhog Day, over and over. griff apparently lives in “April Fool’s Day”.

The Great Barrier Reef formed in its current location 6,000 to 8,000 years ago at the peak of the Holocene Climate Optimum when temperatures were warmer than they are now. The Little Ice Age was a greater threat to the GBR than the slight warming (a few tenths of a degree C in ocean temperature) that we’ve seen in the last 150 years.

The impact first made the world hotter, then cooler, then it returned to Cretaceous-level warmth, only to get even hotter in the Eocene.

Yes, over geologic time, animals move around. In the Cretaceous, crocodilians lived in the Arctic. In the Eemian, the previous interglacial 120 Ka, hippos swam in the Thames at the site of London.

Why is someone from Lithuania commenting on Australian corals. Has he ever seen one close up?

Someone once asked Sarah Palin about her knowledge of Russia or something like that. She replied that she could see Russia from her back yard. Virginijus Sinkevičius can’t even claim he sees the corals from his back yard.

Papers, I don’t need no stinking papers.

The GBR contains over 600 coral species, more than 3/4 of all known species.

Besides moving south, the mix of more and less heat-tolerant species can change.

But many corals like it hot. Modern groups evolved in the Mesozoic, with average sea temperatures higher than now. Max temps were also hotter.

John Tillman
Reply to  John Tillman

The present GBR formed in the Holocene Climatic Optimum, which was globally hotter than now, as were the Egyptian, Minoan, Roman and Medieval Warm Periods, although progressively cooling.

Yes John.
And obviously those corals that live again in the Bikini Islands lagoon like it hot too.
They all came back from obliteration by nuclear bombs in the 1950s to robust health in ~ 60 years.
Talk about resilient.
(But not as resilient as that bloke 2k years ago who apparently resurrected himself a few days after he was offed by some Romans. He has quite a following even today. Not as dedicated as Greta’s followers though. Just ask Griff)

‘a “green and just” recovery from the Covid-19 crisis’

LOL. These people are so incredibly IQ-challenged. Is there no crisis, emergency, or human suffering that they will not try to hijack into their green policies?

How about we address COVID-19 to save human lives? It’s now, real, and has a practical solution.

If they want to help the Great Barrier Reef then address the pollution coming down the rivers (primarily fertilizer run-off). That is measurable and has practical solutions too.

Point being that there is no such thing as natural “ocean acidification” due to increased CO2 to the extent that aquatic plants and animals are negatively effected. The greatest explosion of life in the oceans occurred during the Ordovician and Silurian periods when CO2 levels remained many times what currently are.

Even higher in the Cambrian, ie ~7000 ppm, during which period most animal phyla emerged. In the Ordovician and Silurian, plants, fungi and animals began to move into land.

The current Great Barrier Reef has only been in place for less than 10,000 years. Previously the continental shelf on which it lives was dry land until the oceans rose and corals migrated there and built up the reefs we see today. It is nonsense to suggest it has been around for millions of years.

Dennis
April 1, 2021 7:56 pm

Like all coral reefs the Great Barrier Reef lives, the cycles of death and renewal are constant and at any given time the life cycles will vary across the reef location.

The GBR is however healthy and politically based claims about it disappearing defy logic and fact.

And consider why the GBR is picked on, there are many coral reefs around Australia and globally. Answer of course is cherry picking by leftist warming hoaxers. GBR is a very well known internationally tourist destination so the propaganda spin doctors target it.
