Great Barrier Reef Bleached Again by Climate Change

April 12, 2017


Unprecedented coral bleaching in consecutive years has damaged two-thirds of Australia’s Great Barrier Reef, aerial surveys have shown.

The bleaching – or loss of algae – affects a 1,500km (900 miles) stretch of the reef, according to scientists.

The latest damage is concentrated in the middle section, whereas last year’s bleaching hit mainly the north.

Experts fear the proximity of the two events will give damaged coral little chance to recover.

Prof Terry Hughes, from James Cook University, said governments must urgently address climate change to prevent further bleaching.

“Since 1998, we have seen four of these events and the gap between them has varied substantially, but this is the shortest gap we have seen,” Prof Hughes told the BBC.

    Homo sapiens: a peculiar species who is gripped by the delusional conceit that he can transcend his physical destiny by destroying the environment that sustains his physical condition.

    Only when the last tree has died, the last river has been poisoned and the last fish has been caught will we realize that we cannot eat money.

    The 97-98 El Nino was slightly warmer and bleached the barrier reef. Contemporary articles of the time like this one had the world ending and doom and gloom Apparently somebody forgot to mention them to the coral as it grew back and was bleached in this El Nino. Never mind that the colder water coral will be replaced with warmer water coral should the world ever warm back up to say 1000 AD temperatures.

    • of the reef than the southern areas, being even closer to the tropics. In any case there are a number of variables which affect ocean temperatures, such as localised current flows and adjacent undersea topography, amongst others.
      Your comment is particularly foolish in reference to the 97-98 El Nino. Ocean temperatures have remained warm since the 2015-2016 El Nino relative to seasonal averages and the warm Eastern Australian Current, which runs north to south, has extended further south to affect the island state south of the Australian mainland where I live- Tasmania. Marine species from warmer waters have extended their range south and giant kelp forests off South-Eastern Tasmania are in real trouble, as are marine invertebrates such as
      In effect there has been little respite for the GBR since the first event in 2016.
      Unfortunately, all major political parties here are ignoring the issue of the reef as it is a global issue and just too hard for them, so they debate the usual economic and other bullshit and the reef- well a global treasure which is a hugely essential part of the biosphere, seems to be in terminal deterioration. A crime against humanity and more importantly against the planet, of which both are the same thing. There is no other way to describe it.
      In my opinion the GBR and all world heritage areas of essential importance to the Biosphere need an international managing authority.
      Australia is quite obviously not up to it and I say that as an Australian citizen.

      As usual you are deliberately misusing evidence to spread the lies you believe about climate change.

      In previous posts this week you have spread the lie that sea level rise is only due to thermal expansion and refused to see that a small increase in warming (2/10 of a Watt per m^2) is massive when multiplied over the surface of the Earth.

      You are, like your hero Anthony Watts, utterly discredited as a commentator and frankly a laughing stock. We only respond to you to demonstrate your utter willful ignorance.

    quote: “The world has lost roughly half its coral reefs in the last 30 years…. Even if the world could halt global warming now, scientists still expect that more than 90 per cent of corals will die by 2050. Without drastic intervention, we risk losing them all.”

    To this news, the Tom Bates response is the coral equivalent of “Let Them Eat Cake”. And here is my response to Tom Bates: somebody is going to eat something, when this all plays out.
