The hottest year on record unleashes a mass coral bleaching tragedy

The post questions omission of important data.

 

The post mentioned three areas with Bleaching problems, contradictory to your other posts.

 

No one denies there is bleaching. The point is that it's not permanent and not a problem.

 

And dying is what the Great Barrier Reef Marine Park Authority trying to prevent, before it's too late.

The main culprit behind coral bleaching is rising ocean temperatures. Although bleached coral is not the same thing as dead coral, the fact that it is bleached indicates that it is unhealthy and more vulnerable to death. Unfortunately for the reef, Earth's temperature continues to increase because humans keep burning fossil fuels, which contribute to global heating and climate change, which make bleaching events a regular occurrence.

“What are we doing to stop the reef from being lost?” Ward said. “We cannot expect to save the Great Barrier Reef and be opening new fossil fuel developments. It’s time to act and there are no more excuses.”

 

Coral reefs are thriving around the globe. Coral has existed continuously for the past 40 million years, surviving temperatures and carbon dioxide levels significantly higher and lower than what is occurring today. Since the peak of the last glacial maximum 33-26 thousand years ago, global average temperature reached its highest point approximately 7,000 years ago, at least 1 or 2 degrees C higher than today, during which coral reefs thrived.

Coral requires warm water, not cold water, to live. Coral cannot live outside of tropical or subtropical waters. (See Figure 1.) Coral reefs thrive in locations throughout the globe where temperatures range from site to site by as much as 20 degrees Fahrenheit, from the most Northern or most Southern sites to the most equatorial sites. The temperature at coral reef sites range by over 20 degrees Fahrenheit from Summer to Winter at some locations around the world. Thus, coral reefs have proven to thrive in a substantial range of temperature environments, including temperatures that exceed those where coral bleaching has occurred.

As Earth continues its modest warming since the peak of the Little Ice Age 400 years ago, coral reefs have extended their range toward the poles while still thriving at and near the equator.

Temperature Swings: Short-term heatwaves or cold snaps can cause bleaching events, but historically, such events have occurred long before the recent warming since the peak of the Little Ice Age. Moreover, studies show coral can and have been adapting to the gradual long-term pace of global warming that has occurred since the peak of the Little Ice Age. History shows that cold snaps can harm coral much worse than warm spells. In 2010, colder ocean temperatures off the coast of Florida killed more coral than any warm-water event. And, despite these events, coral reefs recover over the course of several years or sometimes, even quicker.

It was a depressing, if expected inevitability when Western Australia’s Rowley Shoals showed the first signs of mass coral bleaching earlier this year, but a follow-up survey has found a remarkable recovery looks likely to preserve the reef’s near-pristine health — at least for now.

Tom Holmes, the marine monitoring coordinator at the WA Department of Biodiversity, Conservation and Attractions, said that while his team was still processing the data, it appeared the coral had pulled off an “amazing” return towards health over the past six months.

“We were expecting to see widespread mortality, and we just didn’t see it … which is a really amazing thing,” Dr Holmes said.

A poster child for coral alarmism is the Great Barrier Reef. The Great Barrier Reef is 20 million years old, and it has survived significantly warmer and colder temperatures than today. Although the Australian Institute of Marine Science documented that approximately 22 percent of the reef experienced recent bleaching (not 93 percent, as reported in alarmist media stories), 75 percent of the bleached portion of the Reef is expected to make a full recovery. Poor water quality resulting from nearby coastal development is the main culprit for bleached reef areas that do not recover. Evidence shows much of the bleached coral in the Great Barrier Reef has already recovered and the rest is continuing to recover.

Coral Reefs are Dying Because of Climate Change?

 

Didn't need to read past your first false sentence. Just a few posts back, you posted that bleaching was happening. That is NOT "Coral reefs thriving". Warming and CO2 are at unprecedented levels.

 

Thriving and bleaching are not mutually exclusive. Indeed, the latter is part of the former.

 

Like you're some kind of expert. Did you not read that Bleaching is the precursor to Dying? So they are the authorities/experts and they are acting - case closed. You want to overcomplicate this - it's fairly straightforward and simple.

 

Sorry, but research disguised as advocacy remains just advocacy.

 

So "Bleaching" is not the precursor to "Dieing"?

 

No, it is not.

 

Correct. We aren’t using specialized tools to change or modify the shape of coral.

 

Well I think you better write the Australian government and tell them that the Great Barrier Reef Marine Park Authority is ripping them off.
