“Half of all coral colonies on the Great Barrier Reef died over the past two years due to coral bleaching,’’ Dr Veron said.

The Good News

I expect he did say that, but it is not quite true - typical of Xraymike to pick that quote out of all the others.  Only half of the most northern third of the GBR was damaged, and has already been recolonised by the tougher corals. Only reef specialists who have done an exhausting analysis would notice any difference.  The only video people have seen on TV is of the very worst damage that could be found.

The reef will migrate southwards towards colder habitat using offshore currents, and more offshore to avoid sediments washed from rivers and pollution.  The biggest damage to reefs is done by Crown Of Thorns starfish.

The Bad News

Sadly the last male Northern White Rhino has died.  He leaves a daughter and granddaughter, without mating with them.  But most people don't know that there are Southern White Rhinos, and Black Rhinos and Indian, Javan and Sumatran versions.

I'm glad the Aussie reef is more resilient than Mike is suggesting. I've been watching for bleaching in the Caribbean for several years. I know there have been a couple of bad bleaching events, but generally the coral has still been living at least. Not like Florida, where most of it died years ago now. I do think it's been degraded, but it's hard to know how much of that is from boats and tourists who break the coral and poison it with their sunblock.

I expect the hurricanes did a lot of damage. I'm going back next week, although I doubt I'll get to visit St. John since the planned trip is to Virgin Gorda, and the ferry schedules are still messed up. It'll be hard to get there and back in the time I'll have. I don't really know Virgin Gorda that well. Only been to the Baths on day trips. So I won't have any idea of what it was really like before the storms.

I heard about the rhino. Another victim of the vanity of old men who can't get it up. The radio show I heard was so discreet, talked about rhino horn being poached for markets in  "Asia". I suppose it isn't PC to say the Chinese are responsible.


The Aussie reef is in as much trouble as Mike said. The biggest damage to reefs is from bleaching caused by high water temperatures. The Crown of thorns starfish is a minor opportunistic player here in comparison. You are being fed fossil fuel industry Happy Talk misleading information.

Scientists are learning how to stop said starfish. They CANNOT stop the increasing water temperatures which are the main cause of coral death. It's the BURNING of Fossil fuels that is the overwhelmingly greatest cause of coral death!

Palloy's post should be deleted for pushing misleading information.
