GBR not bleaching due to temperature? Great! and thanks for keeping debate honest.
What news of ocean acidity?

"Rising levels of atmospheric carbon dioxide are causing the climate to warm and the oceans to become more acidic. Studies suggest that 20th century warming of approximately 0.6°C may have been beneficial to the growth of some corals and as a result masked the negative effects of declining ocean pH.
However, at some point water temperatures will exceed the thermal optimum for corals and when that happens both rising temperature and falling ocean pH will have a mutually reinforcing, negative effect on the ability of corals to build their calcium carbonate skeletons. Results from controlled laboratory experiments suggest that a doubling in atmospheric carbon dioxide could drive production of carbonate on many reefs below what is needed to replace skeletal damage from natural erosive forces."

Suggesting acidity in Coral Sea naturally fluctuates more than previously thought:

4 climate items in a row? What, no Muslim items in the locker?

Seriously how is anyone supposed to even read 4 seemingly identical items in a row. Yes no doubt there are nuances etc but just the titles tell us they are all about the climate. Which we, humans, can't fix.

Aren't there any other topics than climate and Islam?

What about a bit of bird flu, you know yesterday's fad topic used to frighten the public?

Nice article, that for a change looks at the science rather than the fairytale. I'm waiting for the alarmists to appear and contradict the author, predicting a Venus like global warming scenario where the seas will boil away leaving the coral exposed to die.

"What news of ocean acidity?"
Given that corals have lived through CO2 levels exceeding 2000ppm and most likely exceeding 4000ppm (compared with our measely 380ppm) I daresay this is a non-event as well. It may or may not affect other marine biota but corals will adapt.

I went to your listed web site Dr Coles - Most of what I saw was rhetoric and some what vitriolic - not a whole lot of science going on rather gainsaying at best.

A refreshing article which has the ring of truth.

The Reef is a great favourite with alarmists. I remember about thirty years ago, it was the crown of thorns starfish which was destroying the Reef and "needed urgent action".

The Reef is a perfect target for scaremongering global warming alarmists, and it is great to have the situation put into perspective.

I have visited the Reef many times over the years, so was aware that the greens were using their standard technique of finding a sick but insignificant part of the Reef and pretending, through photo techniques, that it was a universal problem.

It is reassuring to read an authoritative article from someone with the background and qualification of Peter Ridd, and it gives a handy reference to deal with alarmist nonsense.

I looked at the helpful website referred by Dr Coles, and would recommend that no one rely on the judgement of sneekeepete as to its substance.
