Great barrier reef sees record growth

That sounds a lot like https://en.wikipedia.org/wiki/Argument_from_incredulity which is exactly one argument that climate change deniers use.

I'm afraid I'm still inclined to trust the judgement of people who study this for a living.
I was about to say that it sounds like complete bs given that queensland iirc was part of pangaea 500m years ago and located somewhere near the south pole. Also because the current reef actually dates back about 6,000 years. Also if you want to argue that reefs developing and dying off over time with climate change etc means *nothing to see here* then you've got rocks in yr head.

The post wasn't about climate change. It was about the barrier reef making a record recovery. There is no consensus on that, it's a fact. Of course the climate is changing, it always has and always will, like the weather and just about everything else in existence. I'm not denying that. My observation about the reef being there for a long time, suggesting it will likely be there tomorrow is just common sense. I parked my car in a carpark this morning, I'd make a sensible assumption it'll be there when I return tonight. I'm not denying anything by assuming that.

Which is another common line from climate change deniers. The climate has always changed, therefore the current change is nothing special so we needn't worry about it. (And sometimes the argument goes that we can't do anything about the current change and/or that the current change can't be caused by humans.) Again, I'm going to trust the people who study this for a living.

It's also plain common sense to say that the climate changes, but for some reason you keep linking this back to climate change deniers (why?). The post is about the recovery of the great barrier reef, which many, many experts and reports have failed to predict in their "expert" opinions. If I hadn't had an official report proving this, the thread would of been hijacked by those claiming it another conspiracy theory.

Because you used, word for word, a common line used by climate change deniers. And climate change is what's destroying the reefs (both the increase in temperature and the increase in carbon dioxide (the main cause of the increase)).

They describe it in rather balanced terms:

The reef's northern and central parts have the highest amount of coral cover since monitoring began 36 years ago.​
But coral cover in the southern part of the reef has decreased.​
The new coral is particularly vulnerable - meaning the progress could be quickly undone by climate change and other threats, officials say.​

The story adds

The reef has also been damaged by coral-eating crown-of-thorns starfish and tropical cyclones which generate damaging waves.​
Much of the new coral growth - a species called Acropora - is especially exposed to the reef's threats, said Dr Mike Emslie from Aims.​
"This means that... future disturbance can reverse the observed recovery in a short amount of time," he said.​

Which doesn't seem to justify your suggestion
A balanced assessment or opinion on the great barrier reef would of been: "they are in decline at the moment and are likely to rebound in the future".
No, they really don't think the Great Barrier Reef is likely to rebound in the future. I wish we could all feel more optimistic but in this case I just don't think that's justified.

Bruce, I 've made no suggestions or comments denying anything or suggesting that man isn't involved in some way in the decline of the barrier reef. There are lots of problems in that area on top of climate change. My post is about the fact that the reef has made a recovery against decades of doom and gloom reports and news about their "irreversible" demise. This just shows how amazingly resilient nature is and how man can get (predictions) things wrong. There is nothing more I can add.

One part of the reef has grown, with coral they consider to be particularly vulnerable to damage.

So it's good news, but not an indication that the reef is "likely to rebound in the future".

Here is an Obituary written in the Guardian, this clearly shows what the experts were predicting for the great barrier reef. As I said, If one had said we would see record growth, this would have been written off as a conspiracy theory.

Really? It says that "some scientists think it can hold on in an altered state, similar to its previous incarnations". I doubt the idea of part of the reef growing quickly (with coral that's particularly vulnerable to damage, so probably a temporary growth) would have been startling. It might have been thought unlikely.

It's an obituary, how could we have record growth when they are publishing an obituary?

I presume it's because their research lead the scientists behind the obituary to believe it to be the case. Not all scientists agree, and theories change as new evidence comes in, and that's a good thing as far as I'm concerned.

The population of humans on the Earth has doubled since the early 1970s, and that's put pressure on land to house and feed us.
We burn more fossil fuels, take more flights, and drive more cars, all of which adds CO2 to the atmosphere, which adds to ocean acidification, and puts pressure on animal and plant communities like the GB reef by making them live in a slightly more acidic environment than that which they evolved into.
Quickly reproducing species may do ok as long as they have a heterozygotic (genetically diverse) population with enough genetic variation to have members with the traits which mean they can adapt to the changed conditions.
The problem is where there's either isolated populations, or a homozygotic population which can't adapt to the new conditions.
Corals complicate this because they're an example of symbiosis (commensualism), where it isn't a single organism, but two interconnected organisms. They might not both have the traits to survive, and if that's the case, the reef won't do very well. For bigger organisms with slower life cycles, they're really on their uppers, as the rate of change due to climate change may mean they suffer extirpation/local extinction.

TL;DR: Nature is adaptable to change, but if the change is too fast, species may just die out.

I honestly don't think they are helping themselves or anybody else by publishing such grave and extreme headlines. People just won't take them seriously in the event they are actually right. Like the boy who cried wolf. So many others are doing the same thing. Greta Thunberg was telling people to be in a panic and fear climate change. She was interviewed by the US government committe on climate change about her statements, she back peddled and said she didn't mean it literally! But never clarified this at the time. She was then pressed on what she had based such alarming comments on she said nothing or something to that effect.

Then you see new surveys about record recoveries of the great barrier reef. Of course we need to look after the planet, but allow for other possibilities when making public statements.
