Climate Craziness of the Week: 'warming causing lobster cannibalism'

Most idiotic climate claim ever?

I’m pretty sure some people lay awake at night trying to come up with new ways to demonstrate that planet is going to hell in a handbasket. As I pointed out in Why climate change communications is like ‘Shaka, when the walls fell’, it’s all about imagery, not facts.

What better imagery then than turning lobsters into B-movie crustacean cannibals by making a lame-assed “experiment” that you put up on YouTube, complete with movie titles. Of course the non-thinkers are eating this right up, and they don’t even need drawn butter. Watch:

From Climate Desk:

Noah Oppenheim’s plan was simple: Rig a young lobster underneath a waterproof, infrared camera; drop the contraption overboard off the coast of Maine; and see who comes along for a bite to eat. The takers, he expected, would be fish: Cod, herring, and other “groundfish” found in these waters that are known to love a good lobster dinner. Similar experiments conducted in the 1990s showed that apart from being snatched up in one of the thousands of traps that sprinkle the sea floor here—tools of this region’s signature trade—fish predation was the principle cause of lobster death. Instead, Oppenheim, a marine biology graduate student at the University of Maine, captured footage that looks like it comes straight from the reel of a 1950s B-grade horror movie: Rampant lobster cannibalism.

First, lobsters are scavengers, so they’ll take advantage of anything that is stressed, dying, or dead. No surprises there.

Second , the fossil record of clawed lobsters extends back at least to the Valanginian Age of the Cretaceous. So of course, they’ve survived some of the warmest periods of Earth’s history.

Third, it seems there’s a hockey stick in lobsters, all while that warmth induced cannibalism is going on:

The cannibal lobster story is making me downright crabby.
Oh, bad pun. Bad Larry! *slaps self on wrist*

Hi Noah
Despite my attempts at puerile humour earlier I would like to say that your standing and others’ general estimation of your character would soar if you chose to please continue to contribute as you commendably did with your comment above. None are criticising you for your defence of the questionable.In fact, I personally saw saw it as worthy. To quote Wellington on the eve of the battle of Waterloo “I always have use for a man who continues to defend a defenceless position”.
I am not in any way qualified in a climate related field but can decide for myself the merits of an argument and so far have read every comment here and even looked at some of the links provided.
It does seem to me that you have a case to answer.
You are kindly invited to address some of the points raised in this thread.
Please.
Andy

What’s this?

Transactions of the American Fisheries Society 1892
Up to June 11, this year, we have planted 85,350 young lobsters, and have on hand 510,000 eggs.* We cannot keep the young many days, because they are cannibals, and as they moult about three times in the first ten days and are then soft, their brethren devour them. I have fed them crab and lobster meat, clams and beef, with the hope of bribing them to refrain from eating their fellows, but did not succeed. They are persistent cannibals and must be put out at a few days old on rocky bottom, where there are always hiding places for a soft lobster to remain until his skin hardens into a new and larger shell.

What’s this?

1905Transactions of the American Fisheries Society*
The little lobster which hatches from the egg begins to eat
immediately, grows but little until it is about three days old,
when it sheds its skin and becomes a considerably larger sec- ond stage fry. It remains in this stage on an average four or
five days when it moults and grows again and becomes a third
stage fry. Again after five or six days it again moults and be-
comes a fourth stage fry. It is during this stage, that it changes
its habits from a free-swimming larva and takes to the bottom
to assume the habits of a full grown lobster. The whole process,
varying with many factors such as temperature, food, etc., takes
from eleven to twenty-one days.
The difficulties connected with rearing the frv to this later stage are in brief, first, their terrible cannibalism, second,
the difficulty of keeping them properly aerated and free from
fouling from their decaying food, third, the supply of proper
food, fourth, protection from a growth of diatoms and other
vegetable and animal forms, which appears on the surface of
their bodies and prevents them from swimming and feeding….

What’s this?

1915 DIATOMS AND LOBSTER REARING.
1. Actions of Lobster Larvae.
For several days after they are hatched, young lobsters show a desire to occupy
water that is well lighted. They crowd to the lighted side of a glass vessel, and within
a few seconds will have deserted the shaded for the sunny portion of the water in
which they are lying. Otherwise they show little recognition of direction in their
movements, sinking quietly or jerking themselves apparently aimlessly up or down
or laterally through the water, often with their backs or heads downward, and with
their bristly outer leg-branches constantly vibrating. Their spasmodic movements
are probably the result of various stimuli besides that of light, as is shown by the
fact that they seize greedily any small object that seems likely to make them a satis-
factory meal. When the minute lobsters are crowded together, this edible object is
quite likely to be another lobster of the same brood.’ The stronger of the two
immediately shows how fond he is of his relative by eating as much as possible of
him or her. Cannibalism is one of the factor-^ alwavs to be kept in mind in connec-
tion with artificial arrangements for rearing the lobster.

It seems as if lobsters chow each other whether in tanks or in the wild. This claim by Oppenheim about global warming induce lobster cannibalism is utter garbage. Anthony, see my previous 2 comments showing lobster cannibalism during cooler climate times.

In 1910 even crabs liked cannibalism. Wake me up when something is actually being caused by global yawning.

1910 – CRUSTACEAN BLOOD COAGULATION AS STUDIED IN THE ARTHROSTRACA
“…..to time and general cleanliness observed, they live in dozens in such a house for months without any further food supply than is provided possibly by the paper and occasionally by one of their own number falling a victim; for, like crabs, they are given to cannibalism, not merely…”

Noah Oppenheim March 11, 2014 at 11:01 am

The key result of my investigations into predation on juvenile lobsters in the subtidal areas of the Gulf of Maine is that young lobsters are now being cannibalized in the wild frequently enough to be detected in a tethering study, whereas they were not being cannibalized frequently enough to be detected in a similar tethering study twenty years ago. That is a demonstrable fact, peer reviewed by renowned scientists and published in the scientific literature.

What’s this?
.. [and this, and this ]?

Noah: where’s the reference to that earlier tethering study? It appears your assumption that lobster cannibalism behavior changed between the two studies was unwarranted.

Well this whole thing makes me feel better about eating lobsters. I am actually following the Golden Rule: doing unto them as they would do unto each other.

Reuters report on Noah Oppenheim’s study . . .

I’m surprised that this is over a year old. I would have thought that Noah would have been prepared for the type of questions that we had for him, but I guess it’s possible that his study didn’t get much scrutiny since it advanced a CAGW meme.
That being said, I’m still hoping Noah returns to this thread.

I checked the YouTube site to see what sort of comments people leave on this “research”
Quite a lot of people pointed out that cannibalism is normal state in lobsters and known for very long time.
Noah had been aware of this argument for at least 7 months, yet he said nothing. Wobble, don’t hold your breath.

You know, it seems that maybe Noah is a scientist after all- a modern climate concerned scientist, The kind that does not bother to research history. That dodges criticism of his paper. That uses hyped up cheesy videos about his work to mislead people. The kind that claims to be a scientist when he does not even have a grad degree. Who ignores evidence that disproves his thesis in favor of linking the results to ‘climate’.
This lad may have a real future yet!

Rather disappointed. I was hoping that after getting some responses, Noah would have chosen to engage. Sad that he didn’t. Not surprising, just sad.

For the sake of his conscience, I hope he is diong some real introspection. Sadly from what he wrote, he may have had that surgically removed some time ago.
