NOAA (4/15/24) found temperature levels in every ocean high enough to cause coral bleaching.

Record levels of heat in the ocean are causing once-colorful coral reefs around the world to bleach a ghostly white. In April, the National Oceanic and Atmospheric Administration (NOAA) announced the planet’s fourth mass coral-bleaching event on record—the second in the last decade.

While they might look like plants, corals are actually invertebrate animals related to jellyfish. They get their vibrant colors from tiny algae that live on them and provide them with food. But when ocean temperatures become too hot, corals get stressed and expel the algae, losing their food source and color. Starving coral can recover if their environments improve, but the International Panel on Climate Change (IPCC) predicts that even with the Paris Agreement’s allotted warming of 1.5°C over pre-industrial levels, 70–90% of the world’s coral reefs will still die.

Because coral reefs provide such vibrant ecosystems for sea life, mass coral death will impact economies and food security for humans as well. By protecting coasts, sustaining fisheries, generating tourism and creating jobs, it is estimated that coral reefs provide ecosystem services worth trillions of dollars each year (MIT Science Policy Review8/20/20; GCRMN, 10/5/21).

ABC News (7/25/23) reported last year that “ocean temperatures have a strong connection to climate change”—but didn’t mention what climate change is connected to.

In the past year alone, we’ve seen staggering and unprecedented ocean temperatures amid widespread heatwaves. Last summer, water temperatures of more than 100°F were recorded off the coast of Florida (ABC7/25/23). Scientists say the El Niño weather phenomenon, solar activity and a massive underwater volcanic eruption have played a role in recent supercharged ocean temperatures, but the biggest cause of this coral crisis is undisputed: climate change. The IPCC reports that it’s “virtually certain” ocean temperatures have risen unabated since 1970, absorbing more than 90% of excess heat from the climate system. We also know that the burning of fossil fuels changes the climate more than any other human activity does.

Therefore, in order to give the public the most complete understanding of what’s going on—and how we can fix it—reporting on coral bleaching should not only link the phenomenon to climate change, but link climate change to its main culprit: the fossil fuel industry. While much reporting deserves credit for clearly making this connection, some reports from major outlets were still behind, implying the climate crisis might be some sort of act of God, rather than something humans have caused—and have the power to mitigate.

Good news about bad news

Coral bleaching is bad news, but I’d like to take a rare moment to highlight the good news, too: A lot of reporting on this crisis was thorough, setting a solid example of how the increasing number of climate change-related phenomena should be reported on.

Vox (4/26/24) spells it out: “Ultimately, the only real solution is reducing carbon emissions. Period.”

Vox (4/26/24) dedicated a whole piece to climate change’s effects on coral, making that fossil fuel connection. Senior environmental reporter Benji Jones wrote:

Ultimately, the only real solution is reducing carbon emissions. Period. Pretty much every marine scientist I’ve talked to agrees. “Without international cooperation to break our dependence on fossil fuels, coral bleaching events are only going to continue to increase in severity and frequency,” [NOAA marine scientist Derek] Manzello said.

The New York Times (4/15/24) made the fossil fuel connection, too, in an article by Catrin Einhorn: “Despite decades of warnings from scientists and pledges from leaders, nations are burning more fossil fuels than ever and greenhouse gas emissions continue to rise.”

NPR dedicated an episode of All Things Considered (4/17/24) to scientists’ work to breed heat-tolerant corals and algae, in hopes that they can help restore reefs. The piece, by Lauren Sommer and Ryan Kellman, outlined this work’s promise—and its limitations. Heat-tolerant algae may not share as many nutrients with the coral, potentially causing the coral to grow more slowly and reproduce later. Regulators will need to assess whether these lab-grown corals are safe for wild populations and their ecosystems as a whole. Logistically, the sheer amount of heat-tolerant coral needed to replace affected reefs is vast, and it’s only a temporary solution.

“It’s not our ‘get out of jail free’ card,” said Australian coral biologist Kate Quigley:

Maybe that gets us to 2030, 2050, for a very few number of species that we can work with. If we don’t have an ocean to put them back in that’s healthy, no amount of incredible technology or money is worth it.

The episode ended with an acknowledgment that these scientific mitigations are meant only to buy time while humans work to halt climate change, which will require “cutting heat-trapping emissions from the largest source—burning fossil fuels—and switching to alternative energy sources like solar and wind.”

All Things Considered’s coverage of the scientists’ work was impactful because it took time to explain that creating these heat-tolerant corals was an important mitigation, but that the ultimate solution is to cut fossil fuels. Without the latter, the former would be in vain.

Capable of accountability

As a media critic for an organization that’s been at this since 1986, to me it’s heartening when news outlets’ work actually improves. It’s definitely not yet time to pop the champagne—there’s still a chronic lack of clear reporting linking climate disasters to fossil fuels, as FAIR has noted in coverage of last year’s wildfires (7/18/238/25/23), climate protests (9/29/23), the potential breakdown of a crucial Atlantic current (7/31/23), overstating the potential of new carbon-capture technology (1/4/24) and more. But these few coral-focused pieces offer hope that some outlets might be improving their climate reporting practices to include accountability. At the very least, it proves they are certainly capable.

Aside from the effects of the climate crisis becoming harder and harder to ignore each year, there is a commendable movement to train journalists on how best to report on climate through a number of initiatives and organizations. There’s a lot of work to do, but these stories indicate progress since Big Media was applauding Big Oil’s efforts to clean up the Exxon Valdez oil spill in 1989 (Extra!3–4/90) and giving platforms to “scientists” on Big Oil’s payroll who asserted climate change was not occurring (Extra!11–12/045–6/07).

The new denial

CNN (5/9/24) waited until the the 24th paragraph (out of 24) to tell readers that we “need to curb climate-warming carbon emissions.”

Climate denial today is more nefarious. Due to the unanimity and widespread knowledge of the scientific consensus, respectable outlets can no longer parrot views that the Earth isn’t warming. What they can do is bury or gloss over information on its primary cause, who profits off of it, and what needs to be done to prevent it from getting much worse.

In a piece on the potential of artificial reefs to mitigate this crisis that linked coral bleaching to climate change, CNN‘s Michelle Cohan (5/9/24) waited until the very last paragraph to mention the need to “curb climate-warming carbon emissions.” There’s nothing untrue about that statement, but it doesn’t tell you where those emissions come from, and leaves open the interpretation that “curbing” emissions can come from carbon capture and storage—a strategy that is largely industry greenwashing (FAIR.org1/4/24).

Despite likely short-form word limits, a solutions-oriented piece like this does a disservice to readers—and the scientists working on saving corals—by giving such an incomplete sketch of the necessary long-term change. It would benefit from a clear explanation that a) we need to phase out fossil fuels and b) alternative energy sources already exist, are reliable, and are more affordable than fossil fuels already. It’s not arduous or wordy to do so. All Things Considered did most of it in one sentence.

An ABC piece (4/15/24) by Leah Sarnoff and Daniel Manzo covered the coral-bleaching event, but only mentioned climate change in passing toward the end. Otherwise, “warming oceans” were just depicted as something that happened, with no clear connection or cause.

In an article expressing the dire condition of the reefs, the Washington Post‘s Rachel Pannett (4/18/24) likewise made the link to climate change only once: “Climate change is the greatest threat to the Great Barrier Reef, and coral reefs globally,” said Roger Beeden, the chief scientist of the Great Barrier Reef Marine Park Authority.  There was another quote from a research director with the Australian nonprofit Climate Council, who merely noted that the bleaching of the Great Barrier Reef is “a disaster at our doorstep.”

It’s important to express the dire condition the reefs are in, and the devastating risks it poses to ocean and human life. But by only mentioning “climate change” in passing, and not discussing its causes, it comes across as a natural but unfortunate phenomenon. Not highlighting its causes means not highlighting its solutions, either. The result is a potentially paralyzing doomsday narrative that is more likely to dampen than galvanize necessary climate action—especially against fossil fuels.

‘Heat stress’

The word “climate” never appears in this Washington Post piece (4/15/24).

Another Washington Post piece (4/15/24), by Amudalat Ajasa, mentioned the “heat stress” on corals, but not even climate change, let alone the culpability of fossil fuels. This piece quoted NOAA’s Manzello, saying that this global event should be a wake-up call, but didn’t elaborate on what that wake-up call would be for. Wake up to do what? This piece didn’t explain.

The piece also took a grave tone, describing the ghastly reefs off the coast of Florida, Australia and the Caribbean island of Bonaire. It quoted Francesca Virdis, a chief operating officer at Reef Renewal Bonaire: “It’s hard to find a silver lining or a positive note with everything happening.”

The article explained the role of El Niño—a naturally occurring climate pattern that warms areas of the Pacific every 2–7 years—and the hope that it will soon let up and give way to La Niña, its cooler counterpart, but did not explain that the phenomenon plays a smaller role than ongoing, human-caused warming. The aforementioned Vox piece also discussed the role of El Niño, but was sure to specify that reefs have been collapsing long before this current crisis.

The feeling of alarm is justified, but journalists should remind readers that the coral bleaching crisis—and climate change as a whole—are not totally uncontrollable acts of nature. We know what is to blame. While it may be too late to avoid breaching the 1.5°C limit even if we cut emissions tomorrow, the sooner we cease burning fossil fuels, the more catastrophic impacts we’ll avoid.

The message is urgent and dire, but there’s plenty that humans—especially those in power—can do, and there’s plenty journalists can do to make the public aware.

Coral Bleaching ‘Off the Charts’ in Atlantic as NOAA Warns Ocean Going ‘Crazy Haywire’

“We had to add additional bleaching alert levels to appropriately categorize just how hot it was,” said a coral reefs expert at the agency.

The phrase “off the charts” is no exaggeration in the National Oceanic and Atmospheric Administration’s latest warning about a global coral bleaching event that scientists have linked to rising ocean temperatures and heat stress.

Derek Manzello, coordinator of NOAA’s Coral Reef Watch Program, told reporters Thursday that about 60.5% of the world’s coral reefs are now experiencing heat stress severe enough to cause bleaching, which can make the reefs more vulnerable to disease and harm the biodiversity they support.

Manzello said at the press briefing that after observing the first months of the coral bleaching event, which began in early 2023, NOAA changed its existing bleaching alert system because conditions were so abnormally warm in the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea.

The agency’s new bleaching alert system categorizes heat stress for coral reefs on a scale of 1-5, with Alert Level 5 representing ocean heat that could kill “approximately 80% or more of corals on a particular reef,” Manzello said.

“We had to add additional bleaching alert levels to appropriately categorize just how hot it was,” he said, with Level 5 “analogous to a Category 5 hurricane or cyclone.”

“I hate that I have to keep using that word ‘unprecedented.’… But, again, we are seeing unprecedented patterns again this year.”

The world’s oceans, Manzello, said, are going “crazy haywire.”

In the Caribbean this year, heat stress off the coasts of Panama, Costa Rica, Nicaragua, and Colombia are now at levels that in previous years weren’t seen until the summer months.

“I hate that I have to keep using that word ‘unprecedented,'” Manzello told The New York Times. “But, again, we are seeing unprecedented patterns again this year.”

The bleaching that took place last year resulted in coral mortality of at least 50% and as high as 93% in reefs off the coast of Huatulco, Mexico, according to a team of Mexican scientists.

In the Atlantic, fossil fuel-driven planetary heating has been exacerbated by El Niño—the natural phenomenon that causes warmer-than-normal ocean surface temperatures—and has caused the “most unprecedented and extreme” bleaching-level heat stress observed in the past year.

Manzello said 99.7% of reef areas in the Atlantic have experienced heat stress that could cause bleaching.

“The Atlantic Ocean has been off the charts,” he said.

Scientists have recorded four global bleaching events since 1998 and have linked all of them to warmer ocean temperatures. Since 1950, the world has lost half of its coral reefs, according to a 2021 study.

Along with serving marine life, a quarter of which rely on coral reefs at some point in their life cycles, reefs also protect coasts from storms, whose growing severity in recent years scientists have also linked to planetary heating.

The current bleaching event has affected reefs off the coasts of at least 62 countries and territories.

Scientists earlier this year confirmed that 2023 was the hottest year in human history and the warmest year on record for the world’s oceans, which absorb more than 90% of excess heat from greenhouse gas emissions.

“I am very worried about the state of the world’s coral reefs,” Manzello said. “We are seeing [ocean temperatures] play out right now that are very extreme in nature.”

Increasingly Frequent Ocean Heat Waves Trigger Mass Die-Offs of Sealife, and Grief in Marine Scientists

Heat waves recently extended across nearly 30 percent of the world’s oceans, an expanse equivalent to the surface area of North America, Asia, Europe and Africa.

Over the past several years, the temperature of the Earth’s oceans have been spiking high enough to trigger numerous die-offs of marine species, killing millions of corals, fish, mammals, birds and plants. Those mass die-offs also have sent a wave of emotional trauma washing over some researchers watching their life’s work vanish before their eyes. 

“We talk a lot about eco grief, that sense of being overwhelmed and feeling loss,” said Jennifer Lavers, who has been tracking how thousands of seabirds have starved to death during recent ocean heat waves off the coast of western Australia as coordinator of the nonprofit marine research Adrift Lab.

Right now the extreme ocean heat in her region is waning, but globally, marine heat wave conditions extend across nearly 30 percent of the planet’s oceans, a surface area equivalent to all of North America, Europe, Asia and Africa. The harms of long-term gradual ocean warming are well documented, but Lavers said the most recent studies show that increasingly frequent pulses of extreme heat are doing the most damage to marine ecosystems.

With even more mass die-offs of ocean species projected, “scientists are leaving in droves from the field,” she said. “Incredibly skilled, talented, qualified, very passionate people are leaving because no matter what they say, what they do, how many papers they publish … It doesn’t matter.”

The creatures many scientists hoped to help with their research are still in decline and often they are worse off than they were when they started their work, including the flesh-footed shearwaters that she studies, she said.

“That’s the case for me,” she said. “I have to literally say to people that my job is to describe the extinction of a species.”

Great Barrier Reef Suffering Record Coral Bleaching With Damage 59 Feet Below the Surface

The Australian Marine Conservation Society (AMCS) has released video footage showing that the southern portion of the Great Barrier Reef is suffering from deep-sea coral bleaching, reported The Guardian.

The footage shows that the bleaching extends at least as far down as 59.1 feet — the deepest reported during this mass bleaching event, a press release from AMCS said. Some of the corals have begun to die in the face of record marine heat waves.

“I feel devastated. This bleaching event is the worst I have seen. It’s a severe bleaching event,” said Dr. Selina Ward, University of Queensland’s former academic director of the Heron Island Research Station, in the press release.

Ward reported extensive coral bleaching at all 16 southern Great Barrier Reef sites she had visited, saying it was the worst she had seen in three decades.

“I’ve been working on the Reef since 1992 but this [mass coral bleaching event], I’m really struggling with. The diversity of species involved has been hard to deal with. Look at bleached areas, there are many different species that are bleached – many of which are pretty resistant to bleaching so it’s not a pleasant one,” Ward added.

Last week, aerial survey data showed that 75 percent of the reef had experienced bleaching during the current bleaching event, with much of it classed as “high to extreme bleaching.”

During climate change-driven marine heat waves, extended periods of warmer ocean temperatures cause corals to become stressed, which leads them to expel the algae that live in a symbiotic relationship with them. These algae not only give corals their colorful appearance, but they are also their main source of energy, so long periods without them can lead to starvation.

“This new footage shows extensive coral bleaching in southern reefs, but there are images from the central and northern parts that show bleaching is extensive and severe in some of those areas too. Although in-water surveys will take months, the Great Barrier Reef Marine Park Authority has completed the aerial surveys but only released the data. The authority must urgently release the maps to show to the public the extent and severity of this bleaching event,” said Dr. Lissa Schindler, campaign manager with AMCS, in the press release.

NOAA Warns World’s Coral on Verge of ‘Worst Bleaching Event in History of the Planet’

“It’s looking like the entirety of the Southern Hemisphere is probably going to bleach this year,” one scientist said.

Driven by sustained climate-fueled oceanic heating, the planet is on the brink of another mass coral bleaching event that marine biologists warn could kill large swaths of tropical reefs including significant areas of Australia’s Great Barrier Reef.

Scientists are sounding the alarm following months of record ocean temperatures exacerbated by the planetary emergency and the El Niño climate pattern in the Pacific Ocean.

“It’s looking like the entirety of the Southern Hemisphere is probably going to bleach this year,” Derek Manzello of the National Oceanic and Atmospheric Administration’s (NOAA) Coral Reef Watch told Reuters. “We are literally sitting on the cusp of the worst bleaching event in the history of the planet.”

As NOAA explains:

When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.

In 2005, the U.S. lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event. The warm waters centered around the northern Antilles near the Virgin Islands and Puerto Rico expanded southward. Comparison of satellite data from the previous 20 years confirmed that thermal stress from the 2005 event was greater than the previous 20 years combined.

Following the planet’s hottest summer on record last year, the Caribbean suffered its worst recorded bleaching event. The last worldwide bleaching occurred in 2014-17, when scientists say approximately 15% of all reefs experienced major coral deaths. Nearly a third of the Great Barrier Reef’s coral perished during the bleaching.

In the Southern Hemisphere, where summer is ending and ocean temperatures are at or near their annual peaks, there is “basically bleaching all over the place,” according to Manzello.

Matthew England, a professor at the University of New South Wales in Australia who studies ocean currents, recently told TheNew York Times that “the sea ice around the Antarctic is just not growing” and “the temperature’s just going off the charts.”

“It’s like an omen of the future,” he added.

It’s a similar story in the North Atlantic, which “has been record-breakingly warm for almost a year now,” University of Miami hurricane expert Brian McNoldy told the Times. “It’s just astonishing. Like, it doesn’t seem real.”

A 2018 report from the United Nations Intergovernmental Panel on Climate Change estimates that global heating of 1.5°C is likely to result in the loss of 70-90% the planet’s coral reefs over the coming decades.

Current emissions-based forecasts have Earth on track for at least 1.5°C of warming, which researchers say is likely to trigger five climate tipping points: melting of the Greenland and Antarctic ice sheets, mass die-off of warm-water coral reefs, thawing of Arctic permafrost, and collapse of the North Atlantic Subpolar Gyre circulation.

The European Environment Agency’s long-term forecasts for 2071-2100 predict worldwide oceanic heating of 0.5°C-3.8°C, depending on future greenhouse gas emission scenarios.

Scientists say the best way to avert worst-case outcomes for both coral reefs and the climate is to swiftly transition from fossil fuels to renewable energy. Reducing land-based pollution and overfishing are also critical to reef preservation.
