'Huge Wake Up Call': Third of Central, Northern Great Barrier Reef Corals Dead (smh.com.au)

iONiUM quotes a report from The Sydney Morning Herald: More than one-third of the coral reefs of the central and northern regions of the Great Barrier Reef have died in the huge bleaching event earlier this year, Queensland researchers said. Corals to the north of Cairns -- covering about two-thirds of the Great Barrier Reef -- were found to have an average mortality rate of 35 percent, rising to more than half in areas around Cooktown. Bleaching occurs when abnormal conditions, such as warm seas, cause corals to expel tiny photosynthetic algae, called zooxanthellae. Corals turn white without these algae and may die if the zooxanthellae do not recolonize them. "It is fair to say we were all caught by surprise," Professor Hughes, director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, said. "It's a huge wake up call because we all thought that coral bleaching was something that happened in the Pacific or the Caribbean which are closer to the epicenter of El Nino events." The report says, "The northern end of the Great Barrier Reef was home to many 50- to 100-year-old corals that had died and may struggle to rebuild before future El Ninos push tolerance beyond thresholds."

  1. Australia had the UNESCO report censored. by BarbaraHudson · · Score: 5, Interesting

    UNESCO had drawn up a list of world heritage sites that were in danger from climate change, and Australia had the reefs removed because it would hurt tourism.

    Between this and WHO saying there's no real risk to spreading zika so please go the the Olympics, it's obvious that it's all about the money.

    "Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.

    There's much more going on than "some research". Australia is actively breeding coral that is adapted to future conditions (lower pH, more CO2, higher temperatures) and is planning on releasing the results in the wild. I got this from the documentary about the Great Barrier Reef on Discovery Channel, but this article also describes it:
