How students around the world are taking a stand for Gaza | Show Types

Students around the world are raising their voices to protest against Israel’s continuing war on Gaza.

More than 50 universities across the United States have now established Palestine solidarity encampments, demanding action to stop Israel’s war on Gaza.

What started as a student encampment at Columbia University in New York City two weeks ago has turned into a global student movement, expanding to Europe, Australia and Canada.

Student protesters have been met with brutal counterprotests, arrests and suspensions, raising debates around freedom of expression and the future of activism on college campuses.

But beyond the mainstream media’s attempt to reduce this movement to free speech and safety, why are students risking it all for Gaza?

Australia’s Albanese declares ‘national crisis’ after killings of women | Women News

Australia’s Prime Minister Anthony Albanese has branded domestic violence a “national crisis” amid an outcry over the rise in the number of killings of women by their intimate partners, and pledged action to tackle the issue, including new funding to help survivors as well as a crackdown on misogynistic online content.

The measures, announced on Wednesday, came after tens of thousands of Australians rallied across the country, including in the cities of Brisbane, Canberra, Melbourne, Sydney and Perth, demanding the government declare the issue a national emergency.

The protests were prompted by a wave of violence that campaign groups say has seen one woman killed every four days this year as a result of domestic violence.

They also followed a stabbing attack in Sydney in April, during which a knife-wielding assailant killed six people at a busy mall.

Five of his victims were women, and police said it was “obvious” that the attacker was targeting women.

Here’s what you need to know about the issue.

How dangerous is Australia for women?

Campaigners called the weekend rallies following a week in which three women were killed, allegedly by men known to them. This included Molly Ticehurst, a 28-year-old mother who authorities say was murdered by her former boyfriend, weeks after he was granted bail following his detention on charges of raping and stalking her.

In total, some 28 women have been killed this year by their current or former partners and members of their family, according to the campaign group Destroy the Joint.

The figure is almost double the number killed in the same period last year, according to public service broadcaster ABC.

Samantha Bricknell, research manager at the Australian Institute of Criminology, told the ABC that recent data suggested an increase in violence against women, with the rate of women killed by an intimate partner increasing by 31 percent from June 2022 to June 2023. Some 34 such murders took place in that period compared with the same period a year earlier, when 26 women were killed.

The increase defied a longer-term downward trend in Australia.

“What we’re really interested to see going forward … is, is this a sustained increase? That’s something that Australia needs to be worried about,” Bricknell told ABC. “More recent data suggests that it is going up, but hopefully we’ll see that that slight uptick turns around and continues to decrease.”

Government statistics also show one in four women in Australia have experienced violence by an intimate partner or family member since the age of 15. While a cause for concern, the figure is lower than in countries such as France, the United Kingdom and the United States. In the latter, more than one in three women have reported experiencing physical and sexual violence by an intimate partner.

What has Albanese said?

Albanese, who joined protesters in Canberra on Sunday, said he took the rallies as a call to action.

“We need to change the culture. We need to change attitudes. We need to change the legal system,” he told the crowd. “We need to change the approach by all governments because it’s not enough to support victims. We need to focus on the perpetrators and focus on prevention.”

Albanese also responded to calls to declare the issue a national emergency, saying such decrees were a short-term legal avenue intended for use in natural disasters. He did however describe domestic violence as a “national crisis” and scheduled an urgent cabinet meeting for Wednesday to discuss the issue. He said violence against women would be the sole agenda item for the meeting.

What kind of action is the government promising?

Following the cabinet meeting, Albanese announced that his government would invest 925 million Australian dollars ($599m) over five years to provide financial support to women and children trying to escape violence.

Those eligible for the Leaving Violence Program will be able to access up to 5,000 Australian dollars ($3,300) in financial support along with referral services, risk assessments and safety planning, a government statement added.

The national cabinet also unveiled new measures to tackle factors that it said exacerbated violence against women, “such as violent online pornography, and misogynistic content targeting children and young people”. These steps will include legislation to ban deepfake pornography and additional funding to pilot age assurance technologies, it said in a statement.

The cabinet also pledged to explore options to improve police responses to high-risk and serial perpetrators.

It added that ministers will meet again in three months to discuss progress.

Are US campus protests against Israel’s war on Gaza going global? | Israel War on Gaza News

From France to Australia, university students are part of pro-Palestine protests as Columbia students continue encampments.

Clashes between students and police officers have been reported all over the United States during intensifying university protests.

What started as the Gaza solidarity encampment at Columbia University, where students are camping inside campus to push their institute to divest from companies linked to Israel, has since spread to campuses in California, Texas and other states.

Now, more than 20 universities in the US are protesting against Israel’s war on Gaza, where Israel’s military offensive has killed more than 34,000 people and its blockade has caused starvation.

But the protests are not limited to the US, students worldwide have been demonstrating in support of Gaza since the outbreak of the war on October 7. Following the Columbia encampments, the protests have further spread to universities from France to Australia. Here is all you need to know about student protests for Gaza outside of the US:

Which global universities are holding pro-Palestine protests?

  • In Paris, France, Sorbonne University students have taken to the streets. Additionally, the Palestine Committee from Sciences Po, is organising a protest where students set up about 10 tents on Wednesday. Despite a police crackdown, the protesters regathered on Thursday.
  • In Australia, students from the University of Sydney set up pro-Palestine encampments on Tuesday, and they were continuing to protest on Friday. Also, University of Melbourne students pitched tents on the south lawn of their main campus on Thursday.
  • In Italy, Rome, students from Sapienza University organised demonstrations, sit-ins and hunger strikes on April 17 and April 18.
  • Since April 19 night, students from the University of Warwick’s group Warwick Stands With Palestine have occupied the campus piazza located in England, United Kingdom. In Leicester, England, a protest broke out on Monday in which students from the University of Leicester Palestine Society also participated.
  • Last month, students from the University of Leeds occupied a campus building in protest against the university’s involvement with Israel.

What are the demands of student protesters outside the US?

Hicham, a student protesting at Sciences Po, which is also called the Paris Institute of Political Studies, told Al Jazeera, “We have a few demands but one of them is to start investigating all of the ties they [Sciences Po] have with the state of Israel, which [are] academic and financial”.

He added that it has become “extremely hard” to talk about Palestine in France due to the way police respond.

The organisers additionally want Sciences Po to condemn Israel’s actions.

Sorbonne students are calling on the French government to help Palestinians.

The University of Sydney students are demanding that their institute cut ties with Israeli universities and arms manufacturers, the Sydney Morning Herald reported.

The Warwick students have demanded that the university divest from companies that they have identified are funding “genocide” perpetrated by Israel, Warwick’s student-run newspaper, The Boar, reported. The Boar quoted an unnamed student protester saying that, while the US protests had invigorated them, they were planning to take action regardless.

The protest in Leicester on Monday was outside the Elbit Systems UK drone factory, calling for the factory’s shutdown. The student protesters at Leeds last month demanded the suspension of Jewish chaplain Zecharia Deutsch who served in the Israeli army during the war on Gaza.

Is there a police crackdown on pro-Palestine protesters outside the US?

On Wednesday, police broke up the Sciences Po demonstration after the institute made “numerous attempts” to evacuate the students peacefully, AFP reported.

The institute’s Palestine Committee released a statement on Thursday saying the protesters were “carried out of the school by more than 50 members of the security forces,” adding that “around 100” police officers were “also waiting for them outside”.

Hicham said that he and his fellow students had been occupying their school for three days. “We went to one building, they [the university] called the cops on us, we had to get out, so we went to the main historical building,” he said.

“But I think the more repression happens, the more people are mobilising,” he said. “We were maybe 300 people before, [but] now we’re 600.”

The students at Sorbonne were also surrounded by riot police, as shown in an Al Jazeera video from Thursday.

“This will continue as long as we don’t have an open and serious conversation about the issue,” a student from Sorbonne University told Al Jazeera.

Why is Elon Musk feuding with Australia and Brazil over free speech? | Technology

Elon Musk, the self-proclaimed free speech absolutist and CEO of X, Tesla, and SpaceX, is once again at the centre of a heated debate about free speech and censorship.

Since buying X, the platform formally known as Twitter, in 2022, Musk has sparred with governments and public figures around the world about what is acceptable to post online.

The mercurial billionaire is now embroiled in separate legal battles with the governments of Brazil and Australia over their attempts to curtail content deemed to be harmful, such as misinformation, violent material and racist speech.

In each case, Musk has accused government officials of stifling free speech.

But his critics say he is emboldening extremists and cherry-picking cases as he has complied with takedown notices elsewhere.

Why is Musk in a dispute with Brazil?

Musk’s dispute with Brazilian authorities is part of an ongoing debate about how to handle “digital militias” associated with right-wing former President Jair Bolsonaro.

Bolsonaro’s online supporters have been the subject of a five-year investigation by Supreme Court Justice Alexandre de Moraes for allegedly spreading fake news and hate speech during his tenure.

The judge is also overseeing an investigation into a coup attempt by Bolsonaro’s supporters after he lost the 2022 election to current left-wing President Luiz Inacio Lula da Silva.

As part of his investigation, de Moraes banned 150 accounts belonging to the “digital militias” – a fact that was made public earlier this year when media reported that many of those accounts were still active.

The move, which has been controversial in Brazil, piqued the interest of Musk, who in April fired off a series of tweets directed at the judge, calling the bans “aggressive censorship”.

Musk also said X would “lift all restrictions” on the banned accounts, although the platform said it had complied with the orders though it intended to challenge them in court.

“This judge has brazenly and repeatedly betrayed the constitution and people of Brazil. He should resign or be impeached,” Musk said on X. “Shame.”

In response, de Moraes launched an investigation into Musk for obstruction of justice.

Why is Musk at odds with Australia?

As Musk battles it out in Latin America’s most populous country, he is also at odds with Australia’s internet watchdog.

The stoush with the country’s eSafety Commissioner centres on a knife attack carried out on April 16 during a livestreamed service at an Orthodox Assyrian church in Sydney.

Police have charged five teenagers over the attack, including a 16-year-old boy accused of stabbing Bishop Mar Mari Emmanuel and a priest.

After the attack, eSafety Commissioner Julie Inman Grant issued a global takedown notice for videos of the event to X and Meta, the owner of Facebook and Instagram.

Inman Grant has argued that posts of the attack should be taken down everywhere, including outside Australia, as internet users can easily avail of virtual private networks (VPNs) to circumvent domestic geo-blocking.

While Meta complied with the order, X has only geo-blocked the videos in Australia.

On Wednesday, Australia’s Federal Court extended an emergency injunction ordering X to remove the videos.

Musk has refused to back down, accusing Australia of attempting to impose censorship worldwide.

“Our concern is that if ANY country is allowed to censor content for ALL countries, which is what the Australian ‘eSafety Commissar’ is demanding, then what is to stop any country from controlling the entire Internet?” Musk said on X.

Australian Prime Minister Anthony Albanese has in turn accused Musk of thinking he is above the law and being an “arrogant billionaire.”

It remains an open question whether or not the courts will affirm the right of the Australian authorities to order the removal of content viewable outside the country.

What’s next for X?

X’s legal teams are going to be busy.

Earlier this week, Brazil’s de Moraes gave X until April 26 to explain why the platform had allegedly not fully complied with the court order to block certain accounts that authorities say are still active.

Separately, thousands of Bolsonaro supporters rallied to support Musk this week as he continues his legal fight.

In Australia, X is fighting the global takedown order ahead of a court hearing on May 10, with the platform facing fines of about $500,000 for each day of noncompliance.

Musk has signalled that further legal fights are on the horizon.

In January, he pledged to fund legal challenges to Ireland’s pending hate speech legislation

Is Musk a defender of free speech?

Whether Musk is a defender of free speech or a right-wing provocateur is to a great extent in the eye of the beholder.

Since his takeover of X, Musk has dramatically scaled back moderation of the platform and reinstated numerous banned accounts, including that of former United States President Donald Trump.

But Musk’s critics have noted that despite his willingness to spar with Brazil and Australia, he has complied with similar takedown orders from Turkey and India, including content critical of Turkish President Recep Tayyip Erdogan and Indian Prime Minister Narendra Modi.

Some of Musk’s detractors argue that his principles only extend to figures he personally agrees with, such as Brazil’s Bolsonaro and Argentina’s new President Javier Milei.

Meanwhile, although the US is known for its especially permissive laws and attitudes towards speech, other countries have taken a more proactive approach to clamping down on misinformation and hateful content.

‘Arrogant billionaire’: Australia, Musk in war of words over censorship | Social Media

Elon Musk and Australian Prime Minister Anthony Albanese clash over order to remove X posts on church stabbing.

Australia and Elon Musk have escalated their war of words over censorship after an Australian court ordered social media platform X to remove footage of a church stabbing.

An Australian judge on Monday ruled that X must block users worldwide from accessing videos of a knife attack on an Assyrian Christian bishop in Sydney after the country’s internet watchdog sought an injunction.

The Federal Court in Sydney granted the temporary global ban after X had said it would challenge eSafety Commissioner Julie Inman Grant’s notice to remove posts related to last week’s attack on Mar Mari Emmanuel.

Australian Prime Minister Anthony Albanese said on Tuesday that the government was prepared to take on Musk, whom he labelled an “arrogant billionaire who thinks he’s above the law, but also above common decency”.

“What the eSafety Commissioner is doing is doing her job to protect the interests of Australians, and the idea that someone would go to court for the right to put up violent content on a platform shows how out-of-touch Mr Musk is. Social media needs to have social responsibility with it. Mr Musk is not showing any,” Albanese told public broadcaster ABC.

Albanese had earlier said it was “extraordinary” that X had decided to challenge the eSafety commissioner’s notice and denied the issue was a matter of freedom of speech.

Musk, who bought the platform formally known as Twitter in 2022, on Tuesday indicated that he would fight the court order.

“Our concern is that if ANY country is allowed to censor content for ALL countries, which is what the Australian ‘eSafety Commissar’ is demanding, then what is to stop any country from controlling the entire Internet?” Musk said on X.

“We have already censored the content in question for Australia, pending legal appeal, and it is stored only on servers in the USA.”

Musk earlier posted a meme depicting X as being pro-free speech and other social media platforms supporting censorship and propaganda, with the caption: “Don’t take my word for it, just ask the Australian PM!”

Australia’s government has blamed social media posts related to the attack on Emmanuel for inflaming community tensions in multicultural Sydney.

Under its Online Safety Act passed in 2021, Australia has been at the forefront of efforts to hold tech companies responsible for the content posted on their platforms.

Emmanuel, a prominent conservative leader of the Assyrian Christ The Good Shepherd Church in Wakeley in western Sydney, suffered lacerations to his head when he was attacked last Monday during a mass service that was being broadcast online.

More than 50 police officers were injured and 20 police cars damaged in an ensuing riot outside the church.

Emmanuel, who survived the attack, released a message last week saying he was “doing fine, recovering very quickly” and that he had forgiven his attacker.

Police on Friday charged a 16-year-old with terrorism offences in connection with the stabbing.

Australia’s PM criticises Musk’s X over stabbing footage | Social Media

Anthony Albanese says decision to challenge takedown order for content related to church stabbing ‘extraordinary’.

Australian Prime Minister Anthony Albanese has criticised social media platform X for its “extraordinary” decision to fight an order by the country’s internet watchdog to remove footage of a stabbing during a livestreamed church service.

X, owned by tech entrepreneur Elon Musk, announced over the weekend that it would challenge the order to take down content related to the stabbing of an Assyrian Christian bishop during a service in western Sydney.

ESafety commissioner Julie Inman Grant said last week that X had been issued notices to remove material depicting “gratuitous or offensive violence with a high degree of impact or detail”.

“I find it extraordinary that X chose not to comply and are trying to argue their case. We know, I think overwhelmingly, Australians want misinformation and disinformation to stop,” Albanese said during a news conference.

“This isn’t about freedom of expression, this is about the dangerous implications that can occur when things that are simply not true, that everyone knows is not true, are replicated and weaponised in order to cause division and in this case, to promote negative statements and potentially to just inflame what was a very difficult situation. And social media has a social responsibility.”

On Saturday, X said it had “complied with the directive pending a legal challenge” as it did not believe that the orders were within the scope of Australian law.

“This was a tragic event and we do not allow people to praise it or call for further violence. There is a public conversation happening about the event, on X and across Australia, as is often the case when events of major public concern occur,” the social media company said in a statement.

“While X respects the right of a country to enforce its laws within its jurisdiction, the eSafety Commissioner does not have the authority to dictate what content X’s users can see globally.  We will robustly challenge this unlawful and dangerous approach in court.”

Mar Mari Emmanuel, a prominent conservative leader of the Assyrian Christ The Good Shepherd Church in Wakeley in western Sydney, suffered lacerations to his head when he was attacked last Monday during a mass service that was being broadcast online.

More than 50 police officers were injured and 20 police cars damaged in an ensuing riot outside the church.

Emmanuel, who is recovering in hospital, last week released a message saying he was “doing fine, recovering very quickly” and that he had forgiven his attacker.

On Friday, police charged a 16-year-old with terrorism offences in connection with the stabbing.

In Australia, a women-only app is latest front in the war over trans rights | LGBTQ News

Sydney, Australia – Sall Grover says she did not think twice when she blocked Roxanne Tickle, a transgender woman, from her Australian-based women-only app Giggle for Girls.

“It did not register, as we get men trying to enter all the time. Mr Tickle passed our AI facial recognition test, which was deliberately set at 94 percent accuracy, meaning that some men will get through,” Grover, who refuses to refer to transgender women as women, told Al Jazeera.

“The rest we remove manually.”

“When he contacted me by phone and I heard a man’s voice, I hung up, but again, this was not unusual,” Grover added.

Grover’s decision to restrict her app to “cisgender” women – women whose birth sex aligns with their gender identity – has not only put her at the centre of the culture war over gender, but in the legal crosshairs as well.

As someone who identifies as a woman, Tickle argues that she is legally entitled to use services meant for women and has been discriminated against on the basis of gender identity.

In a case being watched around the globe, Tickle is suing Grover under Australia’s Anti-Discrimination Act, relying on a 2013 amendment that added gender identity to the list of protected categories.

At stake are contested definitions of sex and gender and, ultimately, the very question of what it means to be a woman.

For trans activists, a ruling in favour of Tickle, who is seeking 200,000 Australian dollars ($128,320) in compensation, would be a vindication of their long struggle to be treated just like other women.

For so-called gender-critical feminists, a win for Grover would affirm the need for female-only spaces that take into account the essential differences between men and women.

After hearing several days of arguments by the two sides at the Federal Court of Australia in Sydney earlier this month, a judge is expected to hand down his decision in Tickle v Giggle in three to six months.

Grover created Giggle in 2020 upon returning to Australia after a stint working as a screenwriter in Hollywood, where she says persistent social media abuse by men landed her in therapy.

“I wanted to create a safe, women-only space in the palm of your hand,” Grover who spent 500,000 Australian dollars ($320,800) on building the site, said.

As far as Grover is concerned, “women-only” spaces should not include trans women like Tickle.

Tickle, who has undergone vaginal and labial surgery and changed her sex to female on her birth certificate, joined the app in 2021 after her application was accepted by gender recognition software designed to screen out men.

Tickle’s account was restricted about six months later after manual screening.

“The evidence will show that Ms Tickle is a woman,” Tickle’s barrister Georgina Costello told the court, according to local media reports.

“She perceives herself as a woman. She presents herself as a woman.”

Costello also told the court that Grover had mounted a “global campaign” against Tickle, including persistently misgendering her in public statements and selling offensive merchandise featuring her image.

“We say because of the way Grover views transgender women, she was unable to see that a transgender woman is a woman,” Costello said.

Tickle’s lawyers did not respond to a request for comment.

Hilary Kincaid, principal solicitor at Sydney firm Kincaid Legal, said the case is complicated for multiple reasons apart from its contentious subject matter.

“It would be far more clear cut if there were physical premises,” Kincaid told Al Jazeera.

Kincaid said Australia’s arcane laws and regulations for community and sporting clubs will be among the relevant considerations in the case.

“Speaking very generally, you can exclude someone from private premises, depending on the terms of the admission,” she said.

“So if there’s a sign up in a club, saying you have the right to refuse admission at the club’s discretion, that can be allowed.”

The case has drawn significant international attention, particularly through social media, not least because of Grover’s openness to giving media interviews and her efforts to raise funds for her legal defence.

Grover said she has raised about 546,000 Australian dollars ($350,314) so far but initially struggled when she was kicked off a number of fundraising platforms.

“Luckily we had the skills, so we were able to build our own platform,” she said.

The Australian legal stoush is seen as a test case by gender-critical feminists, also known as Trans Exclusionary Radical Feminists (TERF), both at home and in other countries such as the United States, Canada and the United Kingdom.

They argue that businesses and organisations should be able to exclude transgender women for reasons including safety and fairness.

“Gender identity is overriding sex and nobody’s explained why,” Angela Jones, a women’s rights activist and supporter of Grover who co-hosts the TERF Talk Down Under podcast, told Al Jazeera.

“Women’s rights have been taken away, and this has impacted women who are in the lowest socioeconomic background or victims of domestic violence or whatever. We always thought ‘that the rules are reasonable’ and our rights would be granted but in the last three or four years we have found we have no rights at all. We have no single-sex spaces”.

ACON and Transgender Victoria, two of Australia’s leading trans activist groups, declined to comment on the case.

Grover accused trans activists of doing “everything they can” to shut her business down.

“They have taken away not just a valuable service for women, but my livelihood,” she said.

“But if I was just in it for business, I would let others in, it’s important to me that the space is female only. I am in fact the one here who is suffering financial loss.”

While many corporations have expressed their support for trans rights amid growing public acceptance of LGBTQ people in recent years, businesses have also faced blowback for associating themselves with the issue.

Last year, Bud Light suffered a plunge in sales after a conservative backlash to a brief partnership with trans activist and TikTok influencer Dylan Mulvaney.

In the US, Republican-led states have introduced dozens of laws to curtail trans rights, many of them aimed at restricting trans women’s participation in women’s sports and gender-affirming care for minors.

In Australia, the debate has also been polarised, as evidenced by the background of Grover’s lawyer, Katherine Deves, a former parliamentary candidate for the main conservative party.

But while conservative-run businesses pushed back against having to serve LGBTQ people in years gone by – such as, for example, refusing to cater to same-sex weddings on religious grounds – the fight over trans rights has followed a less predictable ideological script.

Many of the critics of trans activism are not religious, or even necessarily conservative, with radical feminists among those leading the charge.

Kincaid, the lawyer, said Tickle v Giggle has parallels with a recent case involving a man who took legal action after being denied entry to an art installation where women are pampered by male butlers and served champagne.

The Tasmanian Civil and Administrative Tribunal ruled that the Museum of Old and New Art (MONA) had discriminated against patron Jason Lau and that men should be allowed to view the installation.

“If MONA had created the Ladies Lounge as a club, the result may have been different,” Kincaid said.

Still, even if the court finds in Tickle’s favour, the level of compensation she might receive is unclear.

“If you are successful under the Act, you are compensated for loss, yet it would be difficult to make an argument that she [Tickle] suffered a specific financial loss,” Kincaid said.

Whatever the outcome of the case, it is all but certain to inflame the acrimonious debate over trans inclusion versus sex-based rights.

Grover said she is ready for any outcome and prepared to fight the case all the way to the High Court of Australia if necessary.

“But if we lose eventually, I will have to reincorporate the business somewhere else,” she said.

World’s coral reefs face global bleaching crisis | Climate Crisis

Coral reefs around the world experiencing mass bleaching, scientists say | Climate News

Along coastlines from Australia to Kenya to Mexico, many of the world’s colourful coral reefs have turned a ghostly white in what scientists say has amounted to the fourth global bleaching event in the last three decades.

At least 54 countries and territories have experienced mass bleaching along their reefs since February 2023 as climate change warms the ocean’s surface waters, the US National Oceanic Atmospheric Administration’s (NOAA) Coral Reef Watch, the world’s top coral reef monitoring body, said on Monday.

“From February 2023 to April 2024, significant coral bleaching has been documented in both the northern and southern hemispheres of each major ocean basin,” Derek Manzello, coordinator of Coral Reef Watch, told journalists.

Corals are invertebrates that live in colonies. Their calcium carbonate secretions form hard and protective scaffolding that serves as a home to many colorful species of single-celled algae.

Coral bleaching is triggered by water temperature anomalies that cause corals to expel the colourful algae living in their tissues. Without the algae’s help in delivering nutrients to the coral, the corals cannot survive.

“More than 54 percent of the reef areas in the global ocean are experiencing bleaching-level heat stress,” Manzello said.

Like this year’s bleaching event, the last three – in 1998, 2010 and 2014-2017 – also coincided with an El Nino climate pattern, which typically ushers in warmer sea temperatures.

Sea surface temperatures over the past year have smashed records that have been kept since 1979, as the effects of El Nino are compounded by climate change.

In turn, Australia’s Great Barrier Reef, the largest coral reef system in the world and the only one visible from space, has been severely impacted, as have wide swathes of the South Pacific, the Red Sea and the Gulf.

“We know the biggest threat to coral reefs worldwide is climate change. The Great Barrier Reef is no exception,” Australia’s Environment Minister Tanya Plibersek said last month.

Caribbean reefs experienced widespread bleaching last August as coastal sea surface temperatures hovered around 1-3 degrees Celsius (1.8-5.4 degrees Fahrenheit) above normal.

Scientists working in the region then began documenting mass die-offs across the region. From the staghorns to brain corals, “everything that you can see while diving was white in some reefs”, marine ecologist Lorenzo Alvarez-Filip from the National Autonomous University of Mexico told Reuters.

“I have never witnessed this level of bleaching.”

At the end of the southern hemisphere summer in March, tropical reefs in the Pacific and Indian Oceans also began to suffer.

Scientists have warned that many of the world’s reefs may not recover from the intense, prolonged heat stress.

“What is happening is new for us, and to science,” said Alvarez-Filip.

“We cannot yet predict how severely stressed corals will do,” even if they survive immediate heat stress, he added.

Recurring bleaching events are also upending earlier scientific models that forecast that between 70 percent and 90 percent of the world’s coral reefs could be lost when global warming reached 1.5 degrees Celsius (2.7 F) above pre-industrial temperatures. To date, the world has warmed by some 1.2 C (2.2 F).

In a 2022 report by the UN Intergovernmental Panel on Climate Change, experts determined that just 1.2 C (2.2 F) of warming would be enough to severely impact coral reefs, “with most available evidence suggesting that coral-dominated ecosystems will be non-existent at this temperature”.

This year’s global bleaching event adds further weight to concerns among scientists that corals are in grave danger.

“A realistic interpretation is that we have crossed the tipping point for coral reefs,” ecologist David Obura, who heads Coastal Oceans Research and Development Indian Ocean East Africa from Mombasa, Kenya, told Reuters.

“They’re going into a decline that we cannot stop, unless we really stop carbon dioxide emissions” that are driving climate change, Obura said.
