Great Barrier Reef Coral Cover Hits Record Levels For Second Year

Dr. Peter Ridd writes: ‘The three or four bleaching events since 2016, which have been widely reported in the media, could not have killed much coral, otherwise the 2022 statistics would not be so good.’
Time to dial down the tedious climate alarmism on this.

Official data released today reveals that Australia’s Great Barrier Reef is in excellent health, with coral cover reaching record levels for the second consecutive year, says Climate Change Dispatch.

The increase will be surprising to members of the public, who are regularly hit with scary stories about coral bleaching and false tales about a reef in long-term decline.

A new note, published today by the Global Warming Policy Foundation, explains that the data shows clearly how a handful of coral bleaching events that have affected the reef since 2016 have had a very limited impact on the overall coral cover.

Dr. Peter Ridd says:

In recent years, the media around the world has been reporting coral bleaching events in increasingly apocalyptic terms. This data proves that they are simply scaremongering.”

GWPF director, Dr. Benny Peiser said:

This is just the latest example of empirical data making a mockery of the catastrophists. For how much longer do they think they can get away with it?”

    Reblogged this on Climatism and commented:
    Why is the great news that the Barrier Reef is in top condition, with record coral cover, being ignored by the MainstreamMedia™️?

    With the daily and constant lecturing and hectoring about the supposed “climate catastrophe/crisis/emergency”, shouldn’t they be ringing the bells and dancing in the street?

    The fact that they are not, and remain largely silent about Reef health, stands as more conclusive proof that ClimateChange™️ has absolutely nothing to do with the environment or “saving the planet” rather a wicked tool to justify complete power and control over every aspect of your life and lifestyle. Aka, global communism.

    Peter Ridd writes:

    ‘The data collected by AIMS shows that the GBR is a robust system
    with rapidly fluctuating coral cover. We must expect that, sometime in
    the future, a sequence of events will cause the coral cover to fall sharply,
    as it did in 2011. We must then remember that this is almost certainly
    natural, and not allow the merchants of doom to depress the children.’

    The coral is not bleached by global warming/climate change. The air in contact with the ocean, long wave radiation does not penetrate water. The coral is bleached by direct sunlight, short wave radiation. The following is by an ocean scientist of long standing.

    How the Oceans Get Warm
    Warming the ocean is not a simple matter, not like heating a small glass of water. The first thing to remember is that the ocean is not warmed by the overlying air.

    Let’s begin with radiant energy from two sources: sunlight, and infrared radiation, the latter emitted from the “greenhouse” gases (water vapor, carbon dioxide, methane, and various others) in the lower atmosphere. Sunlight penetrates the water surface readily, and directly heats the ocean up to a certain depth. Around 3 percent of the radiation from the Sun reaches a depth of about 100 meters.

    The top layer of the ocean to that depth warms up easily under sunlight. Below 100 meters, however, little radiant energy remains. The ocean becomes progressively darker and colder as the depth increases. (It is typical for the ocean temperature in Hawaii to be 26°C (78°F) at the surface, and 15°C (59°F) at a depth of 150 meters.

    The infrared radiation penetrates but a few millimeters into the ocean. This means that the greenhouse radiation from the atmosphere affects only the top few millimeters of the ocean. Water just a few centimeters deep receives none of the direct effect of the infrared thermal energy from the atmosphere! Further, it is in those top few millimeters in which evaporation takes places. So whatever infrared energy may reach the ocean as a result of the greenhouse effect is soon dissipated

    you think the Klimate Klowns will change their thinking? yeah, sure

    Some don’t ignore it, but then claim there are still problems in some areas, or potential problems. The alarm must go on 🙄

    ‘Research Misconduct’: Scientist Falsified Work On Fish Behavior And Reefs

    Yesterday, Science magazine reported that the University of Delaware “found one of its star scientists guilty of research misconduct.” This is a big deal.
    . . .
    Deakin and colleagues documented their concerns in a 2020 paper that sought to replicate the findings of a significant effect of increased carbon dioxide in the ocean, called “ocean acidification,” on the behavior of fish.

    Deakin’s replication failed to reproduce the original findings.
    . . .
    Just recently I was told by another high-ranking IPCC official that they strongly agree with our recent peer-reviewed critiques of out-of-date climate scenarios, but: “Of course, I can never say that in public.”

    Oh, the stories I can tell. Another time.
