Oz Study: Global Warming Could Hurt Fish Friendships

From the Monterey County Weekly:

Global warming could hurt fish friendships.

By Kera Abraham | July 7, 2014

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 strangers—like 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 Atlantic’s 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 sea’s weird behavior is a tough nut to crack, but some of the world’s 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 victim—one that’s easy, but foolish, to ignore. Scientists have found carbon’s fingerprints on the acidifying, depleted and alien-invaded sea. This may be the grisly underbelly of global warming.

We knew fish had schools, but we didn’t know they developed friendships.

  1. What a bunch of BS!!!! This guy couldn’t get a grant to study his stupid fish, so he lied about them being affected by Global Warming in order to get one.

    ‘Global Warming‘ is a Racist Hoax

    Let’s begin with a few facts that are widely known and easily proven and are obvious to anyone. Clouds control the temperature of the surface of the Earth. On a global basis, when we have more clouds, we have cooler temperatures. When there are fewer clouds, we have warmer temperatures.

    It is known that cosmic rays seed clouds by ionizing molecules in Earth’s atmosphere that draw in other molecules to create the aerosols around which water vapor can condense to form cloud droplets. Water vapor is by far the most abundant of what’s called ‘Greenhouse gases’. The low-lying clouds that result then has the effect of cooling the Earth by reflecting incoming sunshine back out to space. Since the Sun’s magnetic field tends to deflect cosmic rays away from the Earth, the planet will be warmer when solar activity is high and, conversely, cooler when it is low.

    Cosmic rays enter the atmosphere at a high rate when solar activity is lower because fewer Sunspots and coronal holes cause less solar wind. This solar wind, when the Sun is active, causes an increase of the magnetic field that protects the Earth. Witness the Northern Lights aka Aurora Borealis (Polar Aurorae) when activity is high. This causes cosmic rays the to be blown clear of the Earth. Thus less cosmic rays which in turn causes the formation of less clouds and that allows more radiation from the Sun to reach the Earth, causing the surface temperature to rise. High solar activity, stronger magnetic field, less cosmic rays, less clouds, higher temperatures. Less solar activity, weaker magnetic field, more cosmic rays, more clouds, lower surface temperatures.

    The Sun goes through cycles of 11 years of higher and lower activity, and there are larger cycles of any number of years. Some of these 11-year cycles are weaker and some are stronger and there are patterns of periods of cycles that are both. During the Maunder minimum (The Little Ice Age 1645 – 1715), sun spot activity was recorded as nearly absent. (Less solar activity, weaker magnetic field, more cosmic rays, more clouds, cooler temperatures) Then solar activity increased, Sunspots were more plentiful causing the warming from that time until 1940, when again solar activity diminished and surface temperatures fell until 1975. Then again solar activity increased and the warming began again until 1997. Now we are again experiencing another weak cycle, resulting in no warming of the Earth since 1997 until now. NONE!!!

    This may also explain to some degree why Mars, Jupiter, Mercury, Venus and all the other planets in the solar system have warmed and cooled at the same times as the Earth, but this process isn’t well understood on planets without an atmosphere. This is a fact! That also explains why we’ve just had our harshest winter that anyone alive can remember and the Antarctic ice sheet is growing to record highs this year.

    FACT: Solar activity is directly responsible for the temperature of all the planets in our solar system! Look up any chart that shows the correlation between solar activity and the temperature of the Earth. They are nearly identical.

    FACT: According to ice core studies, CO2 is a LAGGING indicator behind temperature rise some 800 years. This lag is related to the temperature rise causing the oceans to produce more CO2, but it takes 800 years for the effect to be seen. The fact that the oceans are so massive and deep means it takes hundreds, sometimes thousands of years for the temperature rise or fall to have any effect on it’s production rate of CO2. Thus CO2 has nothing to do with rising temperatures. It’s actually the other way round. High CO2 rates cause growth of plant life and is such an infinitesimal amount of the atmosphere that its effect on temperature cannot even be accurately measured. And man’s contribution to this gas is less than 4% each year.

    As a result of the ‘Global Warming’ hoax, third world nations, especially in Africa, are being prevented from using their abundant supplies of coal, oil and natural gas to produce cheap and reliable electricity. They are being forced to use solar and wind alternatives that are at least three times more expensive. The poorest people on the planet are being coerced in to paying three times as much for energy than developed countries. They don’t have the money, so this has resulted in more environmental devastation, disease, war and death.

    Because they aren’t allowed to use their abundant resources of coal, oil or natural gas, there are no jobs because of the lack of industrialization for lack of electricity. They also must use wood and dung for fuel. Women are forced to chop down trees to fuel their fires for cooking and heat causing even more environmental devastation. The breathing of the smoke from these fires is causing respiratory diseases in their children and the women are dying of cancer at alarming rates and making life unbearable. Thus there is unrest and continuous war for what little resources are left.

    Global Warming is a hoax. Not only is it a hoax, but a cruel and racist hoax perpetrated by white anti-capitalist leftists trying to stop all industrial development and control population growth. They have sentenced millions around the world to death for their ideology and religious fervor. Yes, Global Warming is a religion.

    So, you leftist are not only dupes for believing this lie, but racist murderers by proxy for allowing it to be perpetrated for the enrichment of the bureaucracy that has grown up around it, and the leadership of those who only seek their own wealth and power at the expense of the rest. It’s Satanic!

    Damselfish are anti-social scavengers
    Damselfish are known for caring only about savenging and eating.
    While they do mate…

    Male Damselfish are known as Filial Cannabils eating the eggs and the infant babies

    Damselfish are territorial in primarily guarding their eating spots.

    Damselfish only school to follow another to see if there is more food as eating is all they do.

    Damselfish spend all their time scavenging for food.

    Damselfish are terrritorial when it comes to having their own place and chase other Damsel fish away.

    Damsel fish chase other Damsel fish away leaving them more hungry and unable to mate.

    Some Damsel fish adapt from Marine to fresh water of rivers and streams where it’s warm and more algae to eat.

    (notice the itty bitty fish take on the scuba diver)

    As far as this study goes…

    Australia’s James Cook University simply took a school ‘writer’ John Metcalfe who took the writing from a student’s school assignment and coined student Lauren Nadler a ‘lead investigator’.

    “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.”

    Student Lauren Nadler

    January 2013 – Present (1 year 7 months)

    During my PhD in marine biology at James Cook University, I will examine the kinematics and physiology of schooling behaviour in coral reef fish on the Great Barrier Reef. In addition, I will study how projected increases in ocean warming and dissolved carbon dioxide may mediate the advantages of schooling in gregarious species.

    I will study how “projected (a guess)”
    increases in ocean warming and dissolved carbon dioxide
    “may” (a guess) mediate the advantages of schooling in gregarious species.

      Many articles on the benefits of damselfish cannibalism written in early 2000.

      False: “Under normal ocean conditions, juvenile damselfish take about three weeks recognize their other fish in their schools.”

      Most likely the “simulated conditions with estimated carbon dioxide levels in the year 2100″, was using an aquariam with a heater set higher than the normal temperature setting of 78 degrees recommended for damselfish
      to be comfortable.

      It is likely the simulated condition to come up with the bogus conidition of damselfish with Alzheimers was adding a quart of oil to a ten gallon tank and the damselfish were dying of poison.

      “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.”

      Lauren Nadler still refuses to admit she poisoned the hapless fishies.

      “Whatever the cause,” John Metcalfe does not give a damselfish about, he will now say fish were never to be predators and eat other fish.

      Damselfish Cannibalism Frenzies

      Non-kin egg cannibalism and group nest-raiding by Caribbean sergeant major damselfish (Abudefduf saxatilis)

      Cheney, K. L. February 2008

      SOURCECoral Reefs; Feb2008, Vol. 27 Issue 1, p115
      Academic Journal

      ABSTRACT

      The article discusses the process of egg cannibalism and nest-raiding by Caribbean sergeant damselfish Abudefduf (A) saxatilis in the waters of Barbados.

      Scuba divers have observed that A. saxatilis males have eaten 65 males belonging to their group, where a total of 66 raiding events were observed for 15 hours consuming 90 percent of the eggs found in the nests.

      It reveals that cannibalism and conspecific predation are prevalent in shipwrecks and corals where most A. saxatilis females lay their eggs. ACCESSION #32064450

      As it’s known the dam selfish damselfish do nothing but spend their time hunting and eating.

    As a fishery biologist, this makes me cry. The … i’m crying to hard at the loss of science, ethics, self-control, guidance, and education that our world has come to. This is child’s level science and reasoning.

    We went from building pyramids to Dark Ages (burning books and heretics)
    We went from landing on the moon and droids on other planets and asteroids to …… another dark ages? They are burning books and silencing the heretics.

    When oh when will science make a return?!?

    Quote: “The report took the form of a detective story, tracing the evidence of carbon dioxide’s oceanic rampage:
    Scientists have found carbon’s fingerprints on the acidifying, depleted and alien-invaded sea. This may be the grisly underbelly of global warming.”
