'Dead Corals Don't Make Babies': Great Barrier Reef Losing Its Ability To Recover From Bleaching (cnn.com)
An anonymous reader quotes a report from CNN: Successive ocean heat waves are not only damaging Australia's Great Barrier Reef, they are compromising its ability to recover, raising the risk of "widespread ecological collapse," a new study has found. The 2,300-kilometer-long (1,500 mile) reef has endured multiple large-scale "bleaching" events caused by above-average water temperatures in the last two decades, including back-to-back occurrences in 2016 and 2017.
The new study, released Wednesday in the journal Nature, examined the number of adult corals which survived these two events and how many new corals they created to replenish the reef in 2018.
The answer was as bleak as it was stark: "Dead corals don't make babies," the study's lead author, Terry Hughes, said in a press release. Scientists working on the study found the loss in adult corals caused a "crash in coral replenishment" on the reef, as heat stresses brought about by warming ocean temperatures impacted the ability of coral to heal. "The number of new corals settling on the Great Barrier Reef declined by 89% following the unprecedented loss of adult corals from global warming in 2016 and 2017," said Hughes. Scientists working on the report say they would expect coral recruitment to recover over the next 5 to 10 years, as more corals reach sexual maturity, but only in the absence of another bleaching event. However, with sea temperatures continuing to rise this seems a near-impossiblity.

I'm just as frightened and panicked and filled with righteous moral outrage as I was during the last 87 stories about how everything is doomed this week! We only have 10 more years to save the planet, not counting the previous final 10 years or the penultimate final 10 years before that! Elect politicians that agree with me because all the other ones are bad but the ones I like give really good lip service about pretending to care!
Please enlighten everyone about what happened to the corals in the Great Barrier Reed during the Medieval Warm Period. It was quite warm then, too, yet we still have plenty of corals today.
Oh, wait, we're not supposed to talk about that... I almost forgot.

Dead corals don't make babies
It's the same with everything else.
my girlfriend just blew me. shit was so cash.
News last year was the GBR was showing substantial signs of recovery.
That actual experience contradicts the theoretical findings of this study, so right off the bat you should be suspicious of the conclusions they are leading you to.
I'm not saying it's Fake News per se, but the contradiction does need explanation.

With their "vast science backgrounds" lol. Denialist idiots will always be against any environmental story, it doesn't even matter what it is. They'd rather die than understand science.
In Soviet Russia, dead coral bleaches YOU!
Not even dead ones?
Corals have been around for 500 million years and countles cycles of warming and cooling cycles during that time. They are not going anywhere.
Dump iron into the sea, lads. Iron into the sea...
Read this Wikipedia article about coral reef bleaching.
PLEASE tell me they can't recover.
" They see people almost being denied a supreme court seat because they once had a beer while in school." - No, he perjured himself under oath. It's not the beer, you lying faggot. IT'S THE LYING, YOU LYING FAGGOT.
YOU TELL A LIE UNDER OATH AND YOU ARE A CRIMINAL. That he basically ATTEMPTED TO RAPE A CLASSMATE also didn't really rise to the occasion of a lifetime appointment to the SCOTUS without investigation.
But with TRAITOR SUPPORTING DISHONEST FAGGOTS LIKE YOURSELF in charge? He sailed right through anyway, to lie another day.
Dry your eyes, traitor. Your little perjurer didn't get caught - yet!

Well maybe people would be more on board if you got your stories straight. I just read another article where it said the coral reefs where recovering just fine. Now they are dying off again. Well, which is it? Make up your mind.
You might also have more luck if you didn't let idiot freshman dingbat congress critters write the script.
I read at +2. If your post doesn't reach that level I will not see or respond to it.
" if you got your stories straight. " = Yes, every scientist in the world needs to get their data to align in marching lock step, like Fox News does. There has to be a choral unison of agreement, in all niches. Great point, moron.
to fix it, smells kinda musky. ?

So what you are saying is, you are an evolution denier.
Science - do you speak it motherfucker? Some species evolve, some go extinct.
hand...Tdon't
Who gives a fuck?
It's interesting how the frequency of news articles about environmental disasters seems to be increasing. Is this just because people are more interested in these stories nowadays or is the planet plunging itself in the deep pit of irreversible warming, becoming more unihabitable for people every day?

This. And this is also the reason why I cringe a bit every time I read about 'concensus between scientists,' which 'proves' that for instance climate change is real. A good scientist must always be aware that the established the established models that we use to describe our universe are flawed to a certain extent. So scientists always need to inform the public that considering the data we have now, the insecurities in the data and the models we have, we can say with a certain degree of accuracy that this or that is happening. Most of them do this but unfortunately the media then 'translate' their words to make them more attractive for the public and their subtlety is lost.

It is time to do a proper late term abortion to the GBR asap!
But I basically come here exactly for their comments. It's a bit like reading rebuttals from religious nutjobs who get cornered more and more and come up with more and more ridiculous explanations for clinging to their beliefs.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
No, they don't decrease previously recorded historical temperatures. They take into account changes in methodology. BEST proved that there was no untoward and illicit fiddling with the data.
Capcha: Tedious.
It truly is, with denier zombie claims.
It's not the heat that is bleaching the corals. That's a too-inconvenient scapegoat.
The real culprit is chemical poisoning from human activities near the reefs, most notably oil spillage and sunscreens.
Climate has always changed FOR A REASON. The reason this time the reason is anthropogenic. For fuck's sake you retarded little shitstain, find a new zombie argument.
They need to engineer corals that will not only survive but help the existing corals survive the more hostile environmental conditions.
Restating for emphasis. You would rather die than understand science.

Consensus. You can't even spell it. And it's not lock-step of the data, it's a general aggregate of the science overall that does align very well if not in all possible nth degree extrapolations of the model. The model is very accurate overall.
The people quibbling over whether a moment's data in time is representative or not, you, are missing the bigger picture - it is happening, science has agreed on that. The exact extent cannot be known 100% accurately, but it's all bad.
You instead choose to dither in support of doing nothing, addressing none of it. Faggots like you are not scientists. Faggots like you are liars in defense of polluted monies.
Billion. With a B.
That is how long corals have been around.
If you think driving SUVs is going to be the death of them you are an idiot.
An idiot is a person who reads facts about coral bleaching from experts and, without any evidence, says that the corals will be just fine.
An idiot is someone who can, at their leisure, watch satellite footage showing the shrinking yearly minimum ice extent at the North Pole and claim that rocks falling into the oceans are making the sea level rise.
An idiot is someone who can, on their own computer, look up CO2 level data, average temperature data, hurricane formation, duration, and intensity data, then claim that global warming is a hoax.
An idiot is someone who can look at all sorts of indicators of climate change from many scientific fields, and claim that there is no consensus - therefore more research has to be done.
...an argument over something like this isn't complete without at least one mention of Hitler:
