Major Bleaching Events , Pause Great Barrier Reef Recovery .

'The Guardian' reports that the recovery of the Great Barrier Reef has come to a halt, with scientists citing major bleaching events among a series of other causes.

The effects from the 2022 bleaching event, the fourth in seven years, caused some coral loss on some reefs.

It is likely that those corals which survived bleaching have been affected by reduced growth and reproduction, Australian Institute of Marine Science report, via 'The Guardian'.

According to the latest annual survey of over 100 reefs, a small drop in coral cover was discovered over the northern and central parts of the reef in the past year.

.

The world's largest coral reef system is facing uncertainty while ocean temperatures rise as a result of increased greenhouse gas emissions.

Increased temperatures have resulted in a series of major bleaching events, including four over the past seven years.

.

This demonstrates that even less-severe bleaching events are enough to cause a pause in coral cover, Dr. Mike Emslie, leader of the long-term reef monitoring program at Aims, via 'The Guardian'.

While recovery over the past few years was a positive change, that , “could turn around very quickly with another mass bleaching event, and there’s still the risk from crown-of-thorns starfish and coral disease.”.

However, we are only one large scale disturbance away from a rapid reversal of recent recovery, Dr. David Wachenfeld, research program director at Aims, via 'The Guardian'.

'The Guardian' reports that scientists say that reefs could recover if temperatures are not too extreme, but they could also suffer "sub lethal" effects from bleaching.

.

The reef remains a wonderful, complex and beautiful system, but it is at increased risk with climate change driving more frequent and severe bleaching events, putting increasing pressure on the ecosystem’s resilience, Dr. David Wachenfeld, research program director at Aims, via 'The Guardian'

Coral Reefs Are Heading Toward the Worst Global Mass Bleaching on Record

Coral Reefs Are Heading Toward , the Worst Global Mass Bleaching on Record. According to U.S. government scientists, coral reefs are approaching a fourth global mass bleaching event caused by global heating. According to U.S. government scientists, coral reefs are approaching a fourth global mass bleaching event caused by global heating. The occurrence is expected "to be the most extensive on record," 'The Guardian' reports. . According to the National Oceanic and Atmospheric Administration's (NOAA) Coral Reef Watch. about 54% of ocean waters that contain coral reefs have endured enough heat stress to cause bleaching. The Great Barrier Reef, the largest coral reef system on the plant, also experienced "its most widespread heat stress event" ever this year, 'The Guardian' reports. . Currently, the record for the most widespread bleaching event took place between 2014 to 2017 with 56% of the ocean's coral reefs subjected to heat stress levels severe enough to cause bleaching. Dr. Derek Manzello, the Coral Reef Watch director, said that the current bleaching event is set to surpass that record soon... ... “because the percentage of reef areas experiencing bleaching-level heat stress has been increasing by roughly 1% per week.”. The bottom line is that as coral reefs experience more frequent and severe bleaching events, the time they have to recover is becoming shorter and shorter. , Dr. Derek Manzello, the Coral Reef Watch director, via 'The Guardian'. Current climate models suggest that every reef on planet Earth will experience severe, annual bleaching sometime between 2040 and 2050, Dr. Derek Manzello, the Coral Reef Watch director, via 'The Guardian'. Coral reefs "provide habitat to a quarter of all marine species" but are regarded as one of the most susceptible ecosystems to global warming, 'The Guardian' reports. .
