Skip to comments.Climate Craziness of the Week: Fish living near the equator will not thrive in future warmer oceans

Basic premise of this paper: 1. lets take fish out of their natural ocean environment, 2. put em in a tank where they are stressed, 3. crank up the temperature, 4. see if any fish die, 5. count dead fish, 6. assume natural adaptation is impossible 7. report news of future doom to the world via press release.
Via Eurekalert: According to an international team of researchers, the rapid pace of climate change is threatening the future presence of fish near the equator. Our studies found that one species of fish could not even survive in water just three degrees Celsius warmer than what it lives in now, says the lead author of the study, Dr Jodie Rummer from the ARC Centre of Excellence for Coral Reef Studies at James Cook University.
Dr Rummer and her colleagues studied six common species of fish living on coral reefs near the equator. She says many species in this region only experience a very narrow range of temperatures over their entire lives, and so are likely adapted to perform best at those temperatures.
This means climate change places equatorial marine species most at risk, as oceans are projected to warm by two to three degrees Celsius by the end of this century.

Comments are hilarious ranging from technical (mass of oceans make it impossible for that temperature rise to occur [earth would be unlivable if so - equivalent of setting off 400 atomic bombs per second]) to recipes for fish (Fish, in 350F oil, covered with a nice tempura batter, will not survive). Overwhelming sentiment of those commenting: but never underestimate these guys. The desperation continues to show.
Globull warming alarmist would have you believe that the earth’s temperature has NEVER, EVER been higher than it is right now, which is of course BS.
This is like a weak science fair project in junior high school.
Duh, have “Equator Fish” lost the ability to swim towards cooler water?
Some Wacko is trying to get funding to study Australia reef.
They did the same thing with “Coral Bleaching” back in the ‘90s and “Discovered” the reef has natural cycles.
They will swim off elsewhere ...
Most Fish used to warm water have a hard time in cold water.. most/many die..
BUT..... fish used to cold water mostly can survive in warmer water..
probably the same with mammals.. and insects.... and reptiles..
Takes more giddyup to survive in cold weather.. than in warm..
UNLESS yer talking a desert.. then the reverse is true.. (mostly)...
What did these poor sensitive fish do 10,000 years ago during the last Ice Age?
"..good, ship them up here, we're tired of penguins"
Alternate reality PING!
And I always thought that the temperature of the ocean reduced with depth. I must be wrong because the fish would swim down a few inches if the water seemed too warm for them as they have no doubt done for millions of years. Never mind. These scientists are very clever people much cleverer than fish.
That might be true if the change was very rapid.
However they talk about a century for the change.
The species should adapt to slowly changing temperatures up or down, thru generations of breeding. -Tom
You gotta love Science! It says that a fish can turn into a frog which can turn into a monkey which can turn into a human, but a fish can’t adapt enough to survive a 3 degree temperature change.
Unfortunately, I lost a whole tank of RCS due to a malfunctioning heater (it was ON the whole time).
Sad, but it’s a whole different story.
Similar scientific method, let’s transplant these researchers to Mercury (the planet). They can continue their research on climate change there.
I guess these gray whales are just going for the tacos and cerveza
"Daddy, I turned the little knob..."
Of course had I cranked the dial one tenth of a degree each year from the time I was three until I was 28, I think the fish would have expired in their normal course.
Fish can’t swim away?
How did they survive through past warm periods?
When I was a kid, during late Spring/early Summer swimming in the ponds, we would find the top 6" of water nice and warm, then next two feet down OK and below that... "Brrrrrrrr'!
Later, as an adult I visited Southern California and learned that the Pacific was COLD!
Then I went to Chicago and decided to take a swim in Lake Michigan in early June. I started to wade into the lake, but quit before I got to knee deep. I decided that the War of Northern Aggression was not at all about "Freeing the Slaves".
Them D&^% Yankees were just looking for a warm swimming hole!
News flash for the Global Warmers....
It hasn’t been warmer for almost 15 years.
SHHHHHH!!! Don’t wake up the adults, the Capitalists, Freedom lovers or people who use REAL Science.
I am 100% sure that the “research report” should have said, if it doesn’t, “SOME fish currently iiving near the equator......”
and I am 100% sure that the report should have said, they, the fish they are talking about.......”will not do AS WELL AS now”......
and I am 100% sure that: “will not do as well as now” should be clarified as - “not as well as now NEAR THE EQUATOR.”
the natural processes will involve SOME fish species doing less well than others, in varying degrees, AND among those who NEAR THE EQUATOR begin to do LESS WELL THAN BEFORE they will, by some percentage, seek habitats more conducive to doing O.K.
and, to the extent that SOME species leave and/or dwindle in population NEAR THE EQUATOR, those most able to remain near the equator will likely, having less competition from the species who leave and/or dwindle, wind up doing better
LIFE writ large, including animal and plant life, will not “perish from the earth”, it will adapt as much as it can whenever, whereever and however it can, and in whatever manner it can it will survive - it has for millions of years
It's instinctive for them to do so. The east coast population of Bluefish is a good example. In the spring when coastal water temperatures reach the low fifties, they start appearing in our waters. In late fall when the water temperature drops, they migrate south. I caught an eight pound Blue in the surf, in 48 degree water, on December 8th of a number of years back. That's the latest I've got one here, but a few were taken on offshore wrecks until a week or two into January that year. The water's cooled a bit the last few years; my first Blue in 2013 was a few days into May. Some years it used to be the second week in April.
A cold water fish, the Whiting, when they were abundant, used to thrive in 38-45 degree water and move into the shallows during winter. They called them "Frostfish" because on particularly cold nights, while chasing bait in the surf zone, they'd sometimes be temporarily stunned by super cold wash coming off the beach. They could be scooped up by hand or with a basket or net.
So glad to know that fish have better sense than to become “victims” by decree of the Liberal Greenies!
Now if we could just get humans to be as smart as fish - - - - the stronger mind over the weaker mind———.
It’s working! I feel like a fish already!
