Fish don't have Facebook to help keep tabs on their schoolmates. Like junior high students before the Internet, they have to hang out for a while to become pals.
But a research team at Australia's James Cook University found that ocean acidification, caused by the fossil fuel burning that drives climate change, could be robbing some tropical fish of their ability to remember friends.
Under normal ocean conditions, juvenile damselfish take about three weeks recognize their other fish in their schools. But under simulated conditions with estimated carbon dioxide levels in the year 2100, damselfish apparently lose that ability to distinguish between schoolmates and strangerslike a collective case of fish Alzheimer's.
Lead investigator Lauren Nadler suggests elevated CO2 levels interfere with fish neuroreceptors, impairing senses such as sight and smell, which they use to recognize others.
"Whatever the cause, losing the ability to find friends spells possible trouble for damselfish, as well as other species more valuable to the international economy," writes John Metcalfe, who reports for The Atlantics CityLab in collaboration with Climate Desk. "The Australian research adds another clue to the mounting pile of evidence that climate change will rock the ocean in ways we are just beginning to understand."
The Weekly delved into the trip of ocean acid back in 2008, looking at the connections between Monterey Harbor and its mirror image in the Southern Hemisphere. The report took the form of a detective story, tracing the evidence of carbon dioxide's oceanic rampage:
The seas weird behavior is a tough nut to crack, but some of the worlds sharpest minds are on the case. Their chief suspect is carbon dioxide, code-named CO2: atmospheric loiterer, weather tweaker, planet heater.
CO2 and his gaseous co-conspirators have already been indicted for stealing ice from polar bears, provoking the Creole villainess Katrina, and sparking record-breaking forest fires across the western U.S.
But outside the media bubble, CO2 may quietly be torturing another victimone thats easy, but foolish, to ignore. Scientists have found carbons fingerprints on the acidifying, depleted and alien-invaded sea. This may be the grisly underbelly of global warming.
Even “Darwin” ought to be able to fill in the gaps for that long a time frame and that minor a concern.
What did fish ever DO when the earth’s atmospheric carbon dioxide was double, triple, even more of what it is today?
Were they all hostile to one another and did they go extinct as a result?
I don’t think so.
Globul Warming is the cause of all these Liberals and Democrats and federal judges to do and say insane things.
Couldn’t they were certain tatoos or certain colors of bandanas to know their friends?
Oh Jesus help us, enough of these morons.
...ocean acidification! Absolute nonsense! Geez!
I guess all those volcanoes are spewing out lollipops and kisses.
Also, the ocean floor is layered for MILES with calcium carbonate accretions (ex-sea shells).
This buffers the ocean. They tortured those poor fish with no such thing to help them.
I’ve made friends with some lovely walleye filets. I’m going to coat them in some flour and seasoned bread crumbs and fry them. Then we will be friends forever.
- these morons are too stupid and crazy to be considered humans...
Enough arguing with these global warming idiots. People need to just point and laugh.
You mean Nemo isn’t going to be able to find and rely on his plucky friends to get home? Global warming “research” is turning into pure parody.
On the bright side, if the sea water temperature goes up another 40 or so degrees, fish will be boiled for you when you catch them.
One Volcano creates more pollution than all of mankind has in existence. One!
Globull warming is just one Communist tactic to destroy America. Each and every
person who buys into this crap science deserves a punch in the nose on a cold morning.
These people honestly have no idea how ridiculous they are. They really are that far gone.
Couldn’t the liberal mind also read this as a good thing?
Globull Warming will make everyone less afraid of strangers, we will all sing Kumbaya together and peace will break out.
CO2 must be a good thing!
Unicorns Could Hurt Fish Friendships too - and they’re equally real...
CO2 is the chief suspect. Actually CO2 is the only thing they looked at. It’s the only way they can bring in the coin. CO2 causes old age also. Did you know that.
I think Laura has been smoking large quantities of CO2.
I want fish to have more friends, so I will walk everywhere and sell my car. Then I will go to the looney-bin.
This is satire, isn’t it?
The author of this article, Kera Abraham, could not possibly be stupid enough to actually believe this stuff, right?
Do you mean that I wouldn't age if it wasn't for Global Warming?!?!?!? Curse those evil corporations and their Republican minions!!!
Some of my best friends are fish. If two of them get in a spat, I just sit them down and ask them to say three nice things about each other. But then, I realized that they have a brain the size of a BB, and they can’t talk, so I have a shark eat them.
Hey! Who started the OFST on Monday?
Would some other divers chime in here? Personally, I cannot recall ever seeing damselfish schooling. They are territorial and, except for mating season, tend to fight off anything that comes near their nest/eggs. I have seen pairs, but that is the largest number I recall seeing together. The juveniles aren’t schooling, as I understand the word. They are simply related hatchlings that haven’t yet ventured that far from the brood spot.
It’s been a long time since I was diving. If I am wrong, please tell me.
