Global warming and overfishing. And any good news we can dig up.

Whatever the real reason, its a perfect opportunity for Qld to put some funding pressure on the Feds. Maybe divert some money into Net Free Zones in Moreton Bay.

Maybe people living on the regional side of the "goat cheese curtain" (as I heard Brisbane, Sydney, Melbourne, Canberra described today) will get a bit of attention.

Pauline was having a look around Keppel Island which isn't really part of the GBR but it is in the GBR Marine Park.

Local state pollie is advocating Fed enforcement action 'cos Pauline allegedly interfered with marine life in no-go zone. She touched it. Not kidding!

No wonder people are so p....d off with pollies.

:D There is plenty of coral right up and down the GBR - however, the vast majority of the nth end is dead. Hopefully, the spawning event might give the little tackers somewhere to settle and start growing. here's hoping

The best appreciation of the problem would be among those who have an interest in the business at Lizard Island, where the coral is 100% dead. Perhaps Ms Hanson should have gone there for a chat.

This is a warning event. With future El Nino events it will likely get worse. At what point do governments finally take notice?

And real CO2 action will require a complete overhaul of our economic system because you can't have jobs for all on zero carbon emissions.

Govts will never do anything about a long term problem when they only do things that can be achieved in their short term of 3 – 4 years.
The govt will only react to the noisy wheel issues raised by us. So its up to us to get the ball rolling. But people are really concerned by even shorter term issues that affect them directly. When it all turns to poop, people will then whinge that the govt should do something about it.
Personally, I, like everyone else, don’t give a rats because ill be dead before they do anything

Hanson and her mate Mr ‘show me the empirical evidence’ have NFI. Remember when he tried to argue with Prof Brian Cox requesting empirical evidence?. the Prof handed him numerous pages of data but he ignored it and kept ranting.

Its very scary that Hanson has so many followers and even worse that and her/ mates have so many years making laws that affect us.

It would be good if someone could produce a simple map. Big red blotches where the reef is "dead". Be Orange ones where it is "almost certainly dead" etc. I think there is a fundamental misunderstanding about where is affected and to what degree.

Also the one thing about climate change, it comes along with its mate 'Evolution' which is a wonderful thing.

You only need to look at the Vernon islands, those reefs appear to be quite healthy. Lots of coral. Exposed during big tides. The holes on the reefs surely get as warm as the areas on the GBR. Or maybe they don't? My point is that the reefs here are surviving thus far, and maybe these corals will naturally repopulate those of the GBR.

Sadly at the moment, the misinformation is noisier than the real information. I am sure some people are asking these questions but the media shamefully has a tendency to hear one thing and report another too.

The speed of change will leave most critters behind. Adaption will not be an option for many species.

If warming continues, coral reefs will turn into algae and weed and a few hardy corals.

Yes and no Matt. The speed of change will destroy the populations of many species. Those that survive will likely have the necessary genetic requirements for survival programmed into their DNA. This gets passed on to the next generation and that is how a species evolves, the change is usually very swift at the expense of the majority. It may be though that afterwards there simply is not enough life left to continue a fully functional ecosystem and the remaining life will starve. Again there will be some survivors that adapt and maybe some new residents. There could be a period where these places remain barren until new life that can survive the changed conditions can survive.

There was a link somewhere to a news story where they were artificially causing these evolution events in labs and then reintroducing the coral into the wild to pass on the necessary DNA. We just need to be real careful that we don't make another cane toad farce if we interfere and artificially migrate new species.

All in all its a sad sorry, state that we are in. I think climate change is inevitable and there is little we can do to stop it. But damn, we aren't making it easy for old mother earth are we?

The warmest period in Australia was 1880 to 1890, media fails to report this and shows graphs starting from about 1910.

Carbon dioxide levels are driven by temperature (the sun) and the oceans, first there is a change in temperature then carbon dioxide levels change.

Carbon dioxide is natural, odorless, colorless and tasteless.

Superheated water theory ... https://www.sciencedaily.com/releases/2 ... 121105.htm

Interestingly, it says hot water was noted in Gulf of Carpentaria, so this may well have been responsible for the well publicised mangrove die-off.

A one-off event, or the beginning of the end?
