Comments by "Old Scientist" (@OldScientist) on "Climate change: 400-year record heat threat to Great Barrier Reef | BBC News" video.

The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

@koalaplays8855 Do you have any data to support your cod psychology?

@koalaplays8855 Be generous and share.

@koalaplays8855 Well thanks for trying to provide a link.

@AA-vi1cc "What can be asserted without evidence can also be dismissed without evidence." In God we trust, everybody else brings data.
2
@AA-vi1cc Still no data from you just more vacuous assertions and weak insults. What was the greatest coverage on the reef ever recorded? And how does that compare to recent years?
2
@AA-vi1cc Percentage hard coral cover "provides a simple and robust measure of reef health." So if percentage cover is at record levels the reef MUST BE in robust health.

@AA-vi1cc Give some data to prove what you say.

@AA-vi1cc You've got no data. Come back when you've got some.

@AA-vi1cc Not some vague references. Quote some data. Which years had higher coral cover than the past few years and what was that level cover? How much higher was it than now? How has it changed over time? Come back when you've got something quantitative.
1
@AA-vi1cc Which particular years had higher coverage than the past few years? What were the values for that coverage? How much greater than present? How has coverage changed over time? Quote some data. It would interest me.
1
@AA-vi1cc You don't need to "spell it out". Just quote data. Which years had higher coral cover than the last few? What was the cover value? How did it compare to more recent times? What's the trend? Then try and relate it to the concentration of CO2.
1
@AA-vi1cc And what is wrong with my description of the GCRMN data?
1
@AA-vi1cc Come back when you've got some quality data to share. Or at least some data.
1
@AA-vi1cc You can't answer my questions because you've made up your assertions.
1
@AA-vi1cc You've got no data to contradict the points I made about coral reefs. I supported my points with large scale data.
1
@AA-vi1cc You poor sod. You've got no data to support your argument or you'd quote it. The coral are doing fine shown by the data I quoted. You just make things up.
1
@AA-vi1cc You've got no data to support your assertions.
1
@AA-vi1cc The AIMS data shows GBR coral cover is the highest it's ever been in the last 3 years.
1
@AA-vi1cc The AIMS Long-term Monitoring Programme (LTMP) data for the GBR started in 1985. At the start of the data sequence cover is 25% in 1986. In 2022, the LTMP found record high coral cover on the GBR of 34% coral cover on the seabed of the coral reefs monitored. The 1986 data is the high point of the 80s and 90s.
1
@AA-vi1cc No. The data is for the GBR as a whole.
1
@AA-vi1cc None of this has anything to do with an illusory man-made climate crisis. Corals like it warm. They can't live in cold. Fool.
1
@AA-vi1cc It appears you know nothing.
1
@AA-vi1cc Because you wouldn't quote the data, in fact you daren't quote the data, I quoted it for you. Coral is doing fine. It survived the KT extinction event and the PETM. You're a fool. Go back to bed.
1
@AA-vi1cc You've got no data. Only your assertions. They are worthless.
1
@AA-vi1cc None of this contradicts what I have written, but it does contradict your statement that coral cover was higher in the 80s and 90s.
1
@AA-vi1cc I am fully aware of the three sections and the data for each section. It remains as stated by AIMS and reiterated by me that coral cover is at record levels on GBR. This you incorrectly denied.
1
@AA-vi1cc The points I made in my original comment still stand. AIMS shows record coral cover on GBR. GCRMN shows variable cover for different reef systems. This cover is unrelated to CO2. Biodiversity including reef biodiversity is highest in the warmest parts of the Earth's oceans.
1
@AA-vi1cc At the start of the data sequence for the whole GBR cover was 25% in 1986. It reached a low point in 2011 of 12%. In 2022, the LTMP found record high coral cover on the GBR of 34% coral cover on the seabed of the coral reefs monitored. You cherry pick data from the Southern reef only because it helps your narrative (but it doesn't really). The Northern region reached a low point in 2016. However, it has since completely recovered, with coral cover now at double the 2016 level, and recording record cover. The Central region has experienced a greater degree of fluctuation, but is also now at record high coral cover. The Southern region (your favourite) is now at record equalling coral cover, three times higher than at its low point in 2011. Every region is at record-equalling high coral cover, once uncertainty estimates are taken into account. If you are going to cherry pick. I'm going to cherry pick inside your bunch of cherries. Take Capricorn Bunkers. This is one of the sections within the Southern Region (one of eleven). In 2022, Capricorn Bunkers had record high coral cover of 59%, around four times the lowest value, seen in 2011, of 16%. This doesn't do it justice though as the data for the reef shows a great degree of variability. This is natural. The reef always recovers strongly. And it's got nothing to do with CO2.
1
@AA-vi1cc The data remains the same. GBR record coral cover. No evidence of global scale die off of coral. Greatest diversity of coral in warmest waters.
1
@AA-vi1cc Record GBR coral. No global collapse. Warmest water most diverse coral. Facts.
1
@AA-vi1cc GBR has 3 years of record coral cover. The greatest marine biodiversity occurs in the warmest waters. Warmth is beneficial. The reef is not under heat threat due to human activity.
1
@AA-vi1cc No. The coral are more diverse in warmer waters. If the waters along the coast of Australia warm up, the coral will become more diverse and their spatial range will expand southwards.
1
@AA-vi1cc No. The data regarding what has happened shows, rather than what is guessed at will happen in the future, changes are due to totally natural factors: predation and weather. AIMS has to insert the 'can' and 'threat' statements as it ensures further funding. The facts in the data remain: record coral cover GBR. No collapse in coral cover globally. More diversity in warmer water.
1
@AA-vi1cc Increases in bleaching events has not prevented rapid and record increases in coral cover. Chiming in with AIMS "Percent hard coral cover is one standard measure of reef condition recorded by scientists worldwide, it provides a simple and robust measure of reef health" with that in mind, and it being such a robust measure, let's just say it again: hard coral cover is at record-equalling levels in all three sectors of the GBR. Crown of Thorns Starfish are also a non-problem. Northern: no starfish or no outbreak on all reefs. Central: no starfish or no outbreaks. Southern: out of 30 reefs, 27 had no starfish or no outbreaks. And once more, oh yes, there is record hard coral cover on the Great Barrier Reef. And that is a robust measure of reef health. What a robust reef!
1
@AA-vi1cc You can have feeding scars but that doesn't mean the starfish are definitely there or any issue, so it is classified as no COTS. What I wrote was entirely accurate and as per the report. In the Southern sector: 1 of the 30 reefs was classified as having a Severe Outbreak, 1 reef had an Established Outbreak and 1 reef had a Possible Outbreak. Four reefs classified as No Outbreak (not "varying degrees of severity and feeding" - you naughty little fibber) and the remainder had No COTS. This definitely agrees with what I wrote. Non problem. Only 1 severe outbreak out of 94 surveyed reefs. The Northern and Central sectors definitely recorded record cover in the past few years. The Southern sector is easily record equalling recorded cover when the margins of error are acknowledged. So I'm going to give you a "simple and robust measure of reef health": hard coral cover is at record-equalling levels in all three sectors of the GBR. That is good news.
1
@AA-vi1cc Northern sector "all reefs were classified as either No COTS or No Outbreak" Central sector "There were no Potential, Established or Severe Outbreaks of crown-of-thorns starfish recorded on Central GBR reefs" which means no COTS or No Outbreak (take a look at the map as well). At this point I would like to remind you of a "simple and robust measure of reef health": hard coral cover is at record-equalling levels in all three sectors of the GBR.
1
@AA-vi1cc Only 1 severe outbreaks out of 94 surveyed reefs. Hard coral cover is at record-equalling levels in all three sectors of the GBR. Anybody can look it up for themselves. You're getting boring.
1
@AA-vi1cc let's see... Despite bleaching, despite starfish, despite the weather, despite the desires, invocations, and lies by climate alarmists, the GBR has its highest coral cover ever recorded. Maybe they should change its name to the Greatest Barrier Reef.
1
@AA-vi1cc So let'see... Despite the ravages of starfish, despite the horrors of bleaching, despite the vagaries of the weather, and despite the desires of climate alarmists, the GBR has reached the highest level of hard coral cover ever recorded. We need to rename it the Greatest Barrier Reef!
1
@AA-vi1cc It's abundantly clear that the simple and robust measure of reef health used by scientists worldwide shows that the reef coral cover is at record levels.
1
@AA-vi1cc Two key words: simple and (more importantly) robust. GBR has the largest coral cover ever recorded. Greatest Barrier Reef.
1
@AA-vi1cc It's the Greatest Barrier Reef.
1
@AA-vi1cc And it must sting to have your nose rubbed in the fact that the GBR is in robust health as illustrated by record coral cover. IMHO
1
@AA-vi1cc You descended into insults again.
1
@ceeemm1901 God knows what your handle means.
1
@AA-vi1cc It's not that. You just don't like being wrong. It's understandable.

The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.
