'Huge Wake Up Call': Third of Central, Northern Great Barrier Reef Corals Dead (smh.com.au)
iONiUM quotes a report from The Sydney Morning Herald: More than one-third of the coral reefs of the central and northern regions of the Great Barrier Reef have died in the huge bleaching event earlier this year, Queensland researchers said. Corals to the north of Cairns -- covering about two-thirds of the Great Barrier Reef -- were found to have an average mortality rate of 35 percent, rising to more than half in areas around Cooktown. Bleaching occurs when abnormal conditions, such as warm seas, cause corals to expel tiny photosynthetic algae, called zooxanthellae. Corals turn white without these algae and may die if the zooxanthellae do not recolonize them. "It is fair to say we were all caught by surprise," Professor Hughes, director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, said. "It's a huge wake up call because we all thought that coral bleaching was something that happened in the Pacific or the Caribbean which are closer to the epicenter of El Nino events." The report says, "The northern end of the Great Barrier Reef was home to many 50- to 100-year-old corals that had died and may struggle to rebuild before future El Ninos push tolerance beyond thresholds."
Not sure if joke or you're ignorant of the fact that corals are actually animals and not rocks.
Probably educated in the USA.
Some corals tolerate heat much better than others. We should identify the genes that make that possible, and clone them into other coral species. Some research is being done.
We're debating bathroom peen inspectors in red states as a top priority.
The shepherds did so well protecting the flock that the sheep no longer believed that wolves existed.
UNESCO had drawn up a list of world heritage sites that were in danger from climate change, and Australia had the reefs removed because it would hurt tourism.
Between this and WHO saying there's no real risk to spreading zika so please go the the Olympics, it's obvious that it's all about the money.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
Long live rock!

So:
- why is it happening? ...
- why are the individuals/groups pulling the strings and the press allowing this to happen without yelling and screaming?
(are the "protesters" considered lunatics?)
Maybe dreamland: nothing happens to us, we can afford it... elysium-style
Or - afraid of taking risks to go outside the "normal", loosing the comfort zone
- does not concern me
- too busy making ends meet
It's really bad - one just can wonder what's causing it in human brains to let this happen.
I recently met a guy: global warming does not exist and a huge waterfall of words arguing for why this is the case, impossible to even touch the subject - extremely determined.
I just classify it as religious believe system - no real proof, continuous repetition burns the PROM and it runs forever, if you touch it, it may explode.
Hmmm. Too close to call. I suggest an international spelling bee to decide.
Idiot. They're rising, it's obvious in places like Tuvalu. But the rise is slow - it'll never reach 10 feet any time soon, it's only risen one foot in the last century. But it's got a lot warmer, and that's the real problem. You did read the article, didn't you? Oh no: of course you didn't, you just leapt to make an ignorant comment based on your own stupid belief system. Business as usual, in other words. You should run for office.
The Climate Change deniers will continue to deny it. You can't change their minds – they know what they know, and no amount of science will change their minds. Logic? That's a shibboleth to the deniers. If you use logic on them they just dig in their heels.
Everyone else is already awake.
But the satellite measurements say sea level is rising. Aren't satellites the gold standard? They appear to be when it comes to temperatures.
Tuvalu, really? Plotting the data and running a linear fit results in a 0.3mm change per year, at best. That's about 1.2 inches per century/ I guess that's an obvious rise?
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
"allowed"? Seriously?
Who the hell do you think has the authority to tell the Chinese what is or is not "allowed" in terms of their domestic energy policy?
Let's ignore the fact that the earth has been significantly hotter, by several degree;
What did the coral reefs look like then?
had significantly higher CO2 levels, by several times.
What did the planet look like then? Hint: NOT GOOD FOR US EITHER
Pesticides and Herbicides are the likely true reason our reefs are dying.
Herpes Virus is also killing reefs. However, this report is about reef damage which required a new explanation, not an old one. Those other things are causing steady dieoff, not catastrophic events.
But we'd rather blame CO2 and Global Warming for every environmental problem,
It is a fact that CO2 causes acidification, a fact that this causes reef erosion, and a fact that the ocean cannot sink this acidity as fast as we are causing it. What part of this do you find confusing?
