Guest essay by Eric Worrall
Coral survived the Cretaceous / Paleogene extinction event which wiped out the dinosaurs, when a 6 mile wide Asteroid crashed into the Gulf of Mexico 66 million years ago. Coral survived the Permian–Triassic extinction event 252 million years ago, when the Siberian Traps were formed, a colossal series of volcanic eruptions which covered almost three million square miles in lava, contaminating the entire world with toxic fumes and volcanic ash. But apparently its all going to come to an end, if we add a few hundred ppm more CO2 to the atmosphere.

Summary:
New climate model projections of the world’s coral reefs reveal which reefs will be hit first by annual coral bleaching, an event that poses the gravest threat to one of the Earth’s most important ecosystems.
New climate model projections of the world’s coral reefs reveal which reefs will be hit first by annual coral bleaching, an event that poses the gravest threat to one of the Earth’s most important ecosystems.
These high-resolution projections, based on global climate models, predict when and where annual coral bleaching will occur. The projections show that reefs in Taiwan and around the Turks and Caicos archipelago will be among the world’s first to experience annual bleaching. Other reefs, like those off the coast of Bahrain, in Chile and in French Polynesia, will be hit decades later, according to research recently published in the journal Scientific Reports.
“These predictions are a treasure trove for those who are fighting to protect one of the world’s most magnificent and important ecosystems from the ravages of climate change,” said Erik Solheim, head of UN Environment. “They allow conservationists and governments to prioritize the protection of reefs that may still have time to acclimatize to our warming seas. The projections show us where we still have time to act before it’s too late.”
If current trends continue and the world fails to reduce greenhouse gas emissions, then severe bleaching will occur every year on 99 per cent of the world’s reefs within the century, according to the study.

If there is one aspect of the climate scare which deserves utter ridicule, it is the continuous bad news claims about Coral. Coral is the weed species which will survive the end of the world, because it has already survived multiple global extinction events which killed most other life. There is nothing we could do to the planet which would be worse than the series of world wrecking natural disasters which coral has already shrugged off.

There’s a great little book out that I highly recommend, “Coral Reefs in the Microbial Seas” https://www.amazon.com/Coral-Reefs-Microbial-Forest-Rohwer/dp/0982701209
Although the authors subscribe to the CAGW theory they make it clear that the causes of coral death are overfishing and pollution from human wastes, period. It’s a terrific read by scientists doing work right out there in the trenches.
‘so even if there was bleaching, wouldn’t the coral move towards the poles? Of course it would. Linear thinking on a dynamic system is the terminal illness of doomsters in the past present and future. I have a theory that humans cannot do more than local harm to the planet and even that is temporary no matter what mechanism is contemplated. Warming the planet 2C categorically wouldn’t do it and achieving the 2C by man’s efforts isn’t even worth considering. This planet has survived everything and the temperature hasn’t varied but a couple of percent. The planet’s DNA is ready for anything we’ve got.
Models of models of models. It just goes from sad to stupid. Is anything based on scientific FACTS anymore?
No, because the facts don’t agree with the models…
Prediction: within 100 years 99.99% of all the people currently living on earth will be dead
…and yet, for some strange reason, there’s a 99% probability that the population will have increased!
Good one George , personally when I see ” can” , “might”, “predict” , ” model” I also see the word bullshite.
I think that corals did go extinct during the Ordovician–Silurian extinction event, and new corals evolved during the Triassic to occupy that ecological niche.
…so what you’re saying is that if Climate Change completely wipes them out, no big deal? I agree! (Them little buggers will be back!)
“The Climate system is a coupled non-linear chaotic system and future predictions of climate are not possible”-UN IPCC TAR 2001.
“A coupled system is formed of two differential equations with two dependent variables and an independent variable.”
Sorry if it’s a dumb question but a tripled or quadrupled system is….?
…is basically one that has an indeterminate solution. (Or, take your pick–something will be going on.)
The absolutely true statement: “These predictions are a treasure trove for those who are fighting to protect one of the world’s most magnificent and important ecosystems from the ravages of climate change”
Whether the predictions are accurate or not doesn’t matter – the predictions are great for the propaganda machine.
Reblogged this on Climatism and commented:
Corals evolved during the Cambrian era when atmospheric CO2 levels were at 6,000-7,000 ppm, around 4,000 percent or 20 times higher than today’s “CO2-starved” environment of 400 ppm. With atmospheric temps 10 times higher then today.
Corals have survived millions of years of dramatic and “massive” climate change, yet climate crisis experts want us to believe a few hundred ppm more CO2 to the atmosphere is going to end us?!
Historical climate data simply does not support this claim.
More taxpayer funded “fake climate news”…
You know the story is a crock when this line appears in the University press release:
“The need to act is clear. Between 2014 and 2016, the world witnessed the longest global bleaching event ever recorded, which killed coral on an unprecedented scale. In 2016, bleaching hit 90 per cent of coral on the Great Barrier Reef and killed more than 20 per cent of the reef’s coral.”
I covered this nonsense in “Modern Scientific Controversies Part 2: The Great Barrier Reef Wars“. The claims of “90% bleaching” were false. There was heavy mortality only in the very northern portions of the GBR, much of that already recovering.
“New climate model projections of the world’s coral reefs reveal which reefs will be hit first by annual coral bleaching”
Models “reveal” nothing.
Local stressors (overfishing, pollution) are responsible for the decline in Caribbean coral reefs; warming events are insignificant. See page 20 in Executive Summary of the document Status and Trends of Caribbean Coral Reefs, 1970-2012: https://tinyurl.com/jd2vvdq
High resolution projections which will no doubt yeild very low resolution reality. As all the projections inevitably do.
Interesting – no, very important – read here from report out this past year from the Scripps Institution of Oceanography in San Diego.
Here’s the article: Remote reefs thrive despite climate change – http://www.sandiegouniontribune.com/sdut-sd-me-scripps-coral-reef-health-2016mar20-story.html
Study is here: https://scripps.ucsd.edu/labs/coralreefecology/wp-content/uploads/sites/84/2010/09/smith-et-al-2016.pdf
This is exactly the point made in the book, “Coral Reefs and the Microbial Seas.”

Miami Rosenstiel School of Marine & Atmospheric Science is lucky to get away with global climate models:
– Australian Government ain’t happy with doomsayers on ‘coral reefs’ because of tourism;
– as Austrian Ski-Tourism isn’t happy about ‘our children won’t know what snow is.’

Rosenstiel’s high-resolution projections, based on global climate models, are just another pain in the ass of tourism industry.
