Hottest oceans in 400 years endanger Great Barrier Reef, scientists say

  • Ocean temperatures that were stable for hundreds of years began to rise from 1900 onwards as a result of human influence
  • Since 2016, the reef has experienced five summers of mass coral bleaching, when large sections of the reef turn white due to heat stress

SYDNEY: Water temperatures in and around Australia’s Great Barrier Reef have risen to their warmest in 400 years over the past decade, placing the world’s largest reef under threat, according to research published on Thursday.
The reef, the world’s largest living ecosystem, stretches for some 2,400 km off the coast of the northern state of Queensland. The research is rare in putting the effects of man-made climate change into historical context, as other surveys on damage to the reef have a shorter time frame.
A group of scientists at universities across Australia drilled cores into the coral and, much like counting the rings on a tree, analyzed the samples to measure summer ocean temperatures going back to 1618.


Combined with ship and satellite data going back around a hundred years, the results show ocean temperatures that were stable for hundreds of years begin to rise from 1900 onwards as a result of human influence, the research concluded.
From 1960 to 2024, the study’s authors observed an average annual warming for January to March of 0.12°C (0.22°F) per decade.
Since 2016, the reef has experienced five summers of mass coral bleaching, when large sections of the reef turn white due to heat stress, putting them at greater risk of death.
These summers were during five of the six warmest years in the last four centuries, the study showed.
“The world is losing one of its icons,” said Benjamin Henley, an academic at the University of Melbourne and one of the study’s co-authors.
“I find that to be an absolute tragedy. It’s hard to understand how that can happen on our watch in our lifetime. So it’s very, very sad.”
The last temperature data point, from January to March of this year, was the highest on record and “head and shoulders” above any other year, Henley said.


Coral reefs protect shorelines from erosion, are home to thousands of species of fish, and are an important source of tourism revenue in many countries.
At least 54 countries and regions have experienced mass bleaching of their reefs since February 2023 as climate change warms the ocean’s surface waters, the US National Oceanic and Atmospheric Administration (NOAA) has said.
The Great Barrier Reef is not currently on UNESCO’s list of world heritage sites that are in danger, though the UN recommends it should be added.
Australia has lobbied for years to keep the reef — which contributes A$6.4 billion ($4.2 billion) to the economy annually — off the endangered list, as it could damage tourism.
Lissa Schindler, Great Barrier Reef campaign manager at the Australian Marine Conservation Society, said the research showed Australia needed to do more to reduce its emissions.
“Australia must increase its ambition, action and commitments to battle climate change and protect our greatest natural asset,” she said.

Sahara desert, once lush and green, was home to mysterious human lineage

Sahara desert, once lush and green, was home to mysterious human lineage

  • Archaeological evidence indicates that these people were pastoralists, herding domesticated animals

TRIPOLI: The Sahara Desert is one of Earth’s most arid and desolate places, stretching across a swathe of North Africa that spans parts of 11 countries and covers an area comparable to China or the United States. But it has not always been so inhospitable.
During a period from about 14,500 to 5,000 years ago, it was a lush green savannah rich in bodies of water and teeming with life. And, according to DNA obtained from the remains of two individuals who lived about 7,000 years ago in what is now Libya, it was home to a mysterious lineage of people isolated from the outside world.
Researchers analyzed the first genomes from people who lived in what is called the “Green Sahara.” They obtained DNA from the bones of two females buried at a rock shelter called Takarkori in remote southwestern Libya. They were naturally mummified, representing the oldest-known mummified human remains.

“At the time, Takarkori was a lush savannah with a nearby lake, unlike today’s arid desert landscape,” said archaeogeneticist Johannes Krause of the Max Planck Institute for Evolutionary Anthropology, one of the authors of the study published this week in the journal Nature.
The genomes reveal that the Takarkori individuals were part of a distinct and previously unidentified human lineage that lived separated from sub-Saharan and Eurasian populations for thousands of years.

HIGHLIGHTS

• Sahara was lush green savannah 14,500 to 5,000 years ago

• Isolated lineage of pastoralists inhabited ‘Green Sahara’

“Intriguingly, the Takarkori people show no significant genetic influence from sub-Saharan populations to the south or Near Eastern and prehistoric European groups to the north. This suggests they remained genetically isolated despite practicing animal husbandry — a cultural innovation that originated outside Africa,” Krause said.
Archaeological evidence indicates that these people were pastoralists, herding domesticated animals. Artifacts found at the site include tools made of stone, wood and animal bones, pottery, woven baskets and carved figurines.
The ancestry of the two Takarkori individuals was found to have derived from a North African lineage that separated from sub-Saharan populations around 50,000 years ago. That roughly coincides with when other human lineages spread beyond the continent and into the Middle East, Europe and Asia — becoming the ancestors of all people outside Africa.
“The Takarkori lineage likely represents a remnant of the genetic diversity present in northern Africa between 50,000 and 20,000 years ago,” Krause said.
“From 20,000 years ago onward, genetic evidence shows an influx of groups from the Eastern Mediterranean, followed by migrations from Iberia and Sicily around 8,000 years ago. However, for reasons still unknown, the Takarkori lineage persisted in isolation for much longer than expected. Since the Sahara only became habitable about 15,000 years ago, their original homeland remains uncertain,” Krause said.
Their lineage remained isolated throughout most of its existence before the Sahara again became uninhabitable. At the end of a warmer and wetter climate stage called the African Humid Period, the Sahara transformed into the world’s largest hot desert roughly around 3,000 BC.
Members of our species Homo sapiens who spread beyond Africa encountered and interbred with Neanderthal populations already present in parts of Eurasia, leaving a lasting genetic legacy in non-African populations today. But the Green Sahara people carried only trace amounts of Neanderthal DNA, illustrating that they had scant contact with outside populations.
Although the Takarkori population itself disappeared around 5,000 years ago when the African Humid Period ended and the desert returned, traces of their ancestry persist among various North African groups today, Krause said.
“Their genetic legacy offers a new perspective on the region’s deep history,” Krause said.
 

 


Gaza heritage and destruction on display in Paris

Gaza heritage and destruction on display in Paris

  • Bouffard said the damage to the known sites as well as treasures potentially hidden in unexplored Palestinian land “depends on the bomb tonnage and their impact on the surface and underground”

PARIS: A new exhibition opening in Paris on Friday showcases archaeological artifacts from Gaza, once a major commercial crossroads between Asia and Africa, whose heritage has been ravaged by Israel’s ongoing onslaught.
Around a hundred artifacts, including a 4,000-year-old bowl, a sixth-century mosaic from a Byzantine church and a Greek-inspired statue of Aphrodite, are on display at the Institut du Monde Arabe.
The rich and mixed collection speaks to Gaza’s past as a cultural melting pot, but the show’s creators also wanted to highlight the contemporary destruction caused by the war, sparked by Hamas’s attack on Israel in October 2023.
“The priority is obviously human lives, not heritage,” said Elodie Bouffard, curator of the exhibition, which is titled “Saved Treasures of Gaza: 5,000 Years of History.”
“But we also wanted to show that, for millennia, Gaza was the endpoint of caravan routes, a port that minted its own currency, and a city that thrived at the meeting point of water and sand,” she told AFP.
One section of the exhibition documents the extent of recent destruction.
Using satellite image, the UN’s cultural agency UNESCO has already identified damage to 94 heritage sites in Gaza, including the 13th-century Pasha’s Palace.
Bouffard said the damage to the known sites as well as treasures potentially hidden in unexplored Palestinian land “depends on the bomb tonnage and their impact on the surface and underground.”
“For now, it’s impossible to assess.”
The attacks by Hamas militants on Israel in 2023 left 1,218 dead. In retaliation, Israeli operations have killed more than 50,000 Palestinians and devastated the densely populated territory.

The story behind “Gaza’s Treasures” is inseparable from the ongoing wars in the Middle East.
At the end of 2024, the Institut du Monde Arabe was finalizing an exhibition on artifacts from the archaeological site of Byblos in Lebanon, but Israeli bombings on Beirut made the project impossible.
“It came to a sudden halt, but we couldn’t allow ourselves to be discouraged,” said Bouffard.
The idea of an exhibition on Gaza’s heritage emerged.
“We had just four and a half months to put it together. That had never been done before,” she explained.
Given the impossibility of transporting artifacts out of Gaza, the Institut turned to 529 pieces stored in crates in a specialized Geneva art warehouse since 2006. The works belong to the Palestinian Authority, which administers the West Bank.

The Oslo Accords of 1993, signed by the Palestine Liberation Organization and Israel, helped secure some of Gaza’s treasures.
In 1995, Gaza’s Department of Antiquities was established, which oversaw the first archaeological digs in collaboration with the French Biblical and Archaeological School of Jerusalem (EBAF).
Over the years, excavations uncovered the remains of the Monastery of Saint Hilarion, the ancient Greek port of Anthedon, and a Roman necropolis — traces of civilizations spanning from the Bronze Age to Ottoman influences in the late 19th century.
“Between Egypt, Mesopotamian powers, and the Hasmoneans, Gaza has been a constant target of conquest and destruction throughout history,” Bouffard noted.
In the 4th century BC, Greek leader Alexander the Great besieged the city for two months, leaving behind massacres and devastation.
Excavations in Gaza came to a standstill when Hamas took power in 2007 and Israel imposed a blockade.
Land pressure and rampant building in one of the world’s most densely populated areas has also complicated archaeological work.
And after a year and a half of war, resuming excavations seems like an ever-more distant prospect.
The exhibition runs until November 2, 2025.

US tariffs take aim everywhere, including uninhabited islands

  • The Australian territory in the sub-Antarctic Indian Ocean was slapped with 10% tariffs on all its exports

WASHINGTON: The world’s remotest corners couldn’t hide from US President Donald Trump’s global tariffs onslaught Wednesday — even the uninhabited Heard and McDonald Islands.
The Australian territory in the sub-Antarctic Indian Ocean was slapped with 10 percent tariffs on all its exports, despite the icy archipelago having zero residents — other than many seals, penguins and other birds.
Strings of ocean specks around the globe, including Australia’s Cocos (Keeling) Islands and the Comoros off the coast of Africa, were likewise subjected to 10 percent new tariffs.
Another eye-catching inclusion in the tariffs list was Myanmar, which is digging out from an earthquake that left nearly 3,000 people dead, and whose exports to the United States will now face 44 percent in new levies.
Britain’s Falkland Islands — population 3,200 people and around one million penguins — got particular punishment.
The South Atlantic territory — mostly famous for a 1982 war fought by Britain to expel an Argentinian invasion — was walloped with tariffs of 41 percent on exports to the United States.
The Falklands’ would-be ruler Argentina only faces 10 percent new tariffs.
According to the Falklands Chamber of Commerce, the territory is ranked 173 in the world in terms of global exports, with only $306 million of products exported in 2019. This included $255 million in exports of mollusks and $30 million of frozen fish.

Australia PM Albanese falls off stage during election campaign event

  • Albanese was posing for photos following his speech when he stepped back and lost his footing
  • Albanese promptly got back on his feet and gestured to the crowd with two hands that he was fine

SYDNEY: Australia’s Prime Minister Anthony Albanese appeared to fall off a stage on Thursday during a campaign event for May’s national election, but quickly recovered and insisted he was “sweet” afterwards.
The leader of the center-left Labor party, 62, was posing for photos following his speech at the Mining and Energy Union Conference held in New South Wales, when he stepped back and lost his footing, drawing gasps from the audience.
Albanese promptly got back on his feet and gestured to the crowd with two hands that he was fine.
Video footage from the event showed Albanese had tumbled off the stage, although he shrugged off the incident when asked about it during a radio interview with the Australian Broadcasting Corporation.
“I stepped back one step. I didn’t fall off the stage ... just one leg went down, but I was sweet,” he said.
Albanese is currently on the campaign trail for an election on May 3. The Labor party is running neck-and-neck in opinion polls with the conservative Liberal-National opposition led by Peter Dutton.

Starbucks faces new hot spill lawsuit weeks after $50m ruling

  • The suit, filed at the city’s superior court, claims one of the cups in her order was not properly secured
  • The negligence suit seeks unspecified general and special damages

LOS ANGELES: Starbucks was facing another lawsuit over a spilled hot drink Wednesday, just weeks after a court ordered the coffee giant to pay $50 million to a man who was injured by a cup of tea.
A lawsuit lodged in California claims Sabrina Michelle Hermes was seriously hurt when hot liquid tipped into her lap at a drive-through in Norwalk, near Los Angeles, two years ago.
The suit, filed at the city’s superior court, claims one of the cups in her order was not properly secured when it was handed to her, and the drink sloshed out onto her legs, a hip, a knee and her feet, causing severe injuries.
Starbucks “owed a duty to exercise reasonable care with respect to the preparation, handling and service of hot beverages so as to prevent them from spilling onto and injuring customers such as plaintiff,” the suit says.
The negligence suit seeks unspecified general and special damages, including reimbursement for past and future medical costs and lost earnings.
A spokesperson for Starbucks told AFP on Wednesday the company would be contesting the claim.
“We have always been committed to the highest safety standards in our stores, including the handling of hot drinks,” the spokesperson said.
“We are aware of Ms. Hermes’ claims and firmly believe they are without merit. We look forward to presenting our case in court.”
Last month a jury in Los Angeles ordered the firm to pay $50 million to delivery driver Michael Garcia, who suffered burns when a super-sized drink spilled in his lap at a drive-through.
Garcia’s lawyers claimed the server who handed him three large drinks in February 2020 did not push one of them into the cardboard cupholder properly.
Starbucks said at the time of the ruling that it would appeal the award, which it said was “excessive.”
A landmark legal ruling against McDonalds in New Mexico in 1994 established something of a precedent for Americans suing fast food companies when 79-year-old Stella Liebeck was awarded over $2.8 million after spilling hot coffee on herself.
Although the award was reduced on appeal, the case was often cited as an example of the need to reform US tort laws.
