WASHIGNTON: Polar bears face an existential threat from the rapid decline of Arctic sea ice, which they rely on as platforms to hunt seals.
But in a new study, scientists have identified an isolated subpopulation of polar bears in Southeast Greenland that instead make use of freshwater ice pouring into the ocean from the region’s glaciers, suggesting this particular habitat is less susceptible than others to climate change.
Their findings, described in the journal Science on Thursday, open up the tantalizing possibility that at least some pockets of the species might be able to survive further into this century, when Arctic sea ice is expected to disappear completely during summer months.
“One of the big questions is where in the Arctic will polar bears be able to hang on, what we call ‘persist,’” first author Kristin Laidre, a polar scientist at the University of Washington and Greenland Institute of Natural Resources told AFP.
“I think that bears in a place like this can teach us a lot about where those places might be.”
Laidre and colleagues first spent two years interviewing Inuit subsistence hunters who provided input and ecological knowledge, including harvest samples for analysis.
They then began their own field work, which lasted from 2015 to 2021, in a harsh region that was long understudied because of its unpredictable weather, heavy snowfall and jagged mountains.
Each year, the team would spend one month in springtime, staying in the nearest settlement Kuummiit, which is a two-hour helicopter ride from where the bears live. Fuel depots had to be staged along the route in advance down the coastline, creating a hopskotch-like commute to work.
The team tagged the bears with satellite tracking devices, and collected genetic samples by either capturing bears or firing biopsy darts into their rumps.
Thought to number a few hundred individuals, “they are the most genetically isolated population of polar bears anywhere on the planet,” said co-author Beth Shapiro, a geneticist at the University of California, Santa Cruz and investigator at the Howard Hughes Medical Institute, in a statement.
“We know that this population has been living separately from other polar bear populations for at least several hundred years.”
Unlike their cousins, the Southeast Greenland polar bears were found to be homebodies, seldom straying far to hunt.
Their isolation arises from the geography: they live in a complex landscape of fjords on the very edge of their range on the southern tip of Greenland, well below the Arctic circle, with nowhere to go.
To the west there are an enormous set of mountains and the Greenland Ice Sheet, and to the east the open water of the Denmark Strait all the way to Iceland. They also have to contend with a rapid current that flows southward along the coast.
“We see that when they get caught in this current they jump off the ice and they walk back home to their fjords,” said Laidre. The team found that some of the tracked bears accidentally caught in this situation had to trek more than a hundred miles back home.
While sea ice provides hunting platforms for most of the Arctic’s roughly 26,000 polar bears, the Southeast Greenland bears have access to sea ice for only four months, between February and late May.
For the remaining eight months they rely on chunks of freshwater ice breaking off the Greenland Ice Sheet in the form of marine-terminating glaciers.
“These types of glaciers do exist in other places in the Arctic, but the combination of the fjord shapes, the high production of glacier ice and the very big reservoir of ice that is available from the Greenland Ice Sheet is what currently provides a steady supply of glacier ice,” said another co-author Twila Moon of the National Snow and Ice Data Center in a statement.
There remains much to study about the Southeast Greenland polar bears. Measurements show the adult females are a little smaller than average and they appear to have fewer cubs, but it’s hard to infer much about what that means in the absence of long term data.
Laidre is keen to not oversell the study as one of hope. Polar bears — which in addition to being iconic in their own right are also a vital resource for indigenous people — aren’t going to be saved without urgent climate action.
But this population might have a better shot, and there are similar areas with marine-terminating glaciers on other parts of Greenland’s coast as well as the island of Svalbard that might become small-scale climate refugia.
“We as a community need to look at places like this and ask ourselves, is this a place where we might be able to have some small numbers of polar bears persisting in an ice-free Arctic?” said Laidre.

Used missiles for sale: Iranian weapons used against Israel are up for grabs on Jordan-based website
Used missiles for sale: Iranian weapons used against Israel are up for grabs on Jordan-based website
- Debris used in attack listed on OpenSooq online marketplace
LONDON: Fragments of missiles launched by Iran during the recent attack on Israel have been discovered for sale on Jordan’s prominent OpenSooq website, which is known for trading goods, including vehicles and real estate.
Al Arabiya reported on Sunday that the shrapnel was being advertised, with pieces described as “Used Iranian ballistic missile in good condition for sale,” and “One-time use ballistic missile for sale at an attractive price.”
The sellers had provided specifications and images of the missiles, describing them as “excellent type,” and mentioned their involvement in an “accident” resulting in “severe damage to the body.”
Some listings even included installment payment options.
Iran launched drones and missiles toward Israel late on Saturday as it retaliated following a suspected Israeli strike on the consulate annex building adjacent to the Iranian Embassy in Damascus, Syria, earlier this month.
While most projectiles were intercepted by a joint response from Israel, the US, UK, France, and Jordan, the attack marked Iran’s first direct military assault on Israeli territory, escalating tension and uncertainty in the region.
Following the attack, individuals shared photographs online showing debris that had fallen on Jordanian territory in areas such as Al-Hasa, Marj Al-Hamam, and Karak Governorate.
The Jordanian government confirmed that it had intercepted some flying objects in its airspace, with no reported damage or injuries.
Debris from such incidents often holds economic value. Metal debris from the Iraq War has been used by Iran-backed groups to finance their activities.
Similar items are sold online as military memorabilia, and there has been a surge in demand for such artifacts, as seen in Australia last year, preceding the country’s ban on the sale of hate symbols.
Google Doodle celebrates Lebanese-American poet and artist Etel Adnan
- Etel Adnan rose to fame for her 1977 novel Sitt Marie Rose about the Lebanese civil war
DUBAI: Google released its latest Doodle on Monday honoring Etel Adnan, a Lebanese-American poet, essayist and visual artist, considered one of the most accomplished Arab-American authors of her era.
The poet, who rose to fame for her 1977 novel Sitt Marie Rose about the Lebanese civil war, was born in Lebanon in 1925 to a Greek mother and a Syrian father, and grew up in multiple cultures, languages, nationalities and religions. Sitt Marie Rose won the France-Pays Arabes award and become a classic of war literature, so much so that it is taught in American classrooms.
In 1949, Adnan went to Paris to study philosophy at the Sorbonne before going to America to study at Harvard and Berkeley.
From 1958 to 1972, she taught philosophy in California, during which time she also started painting and writing poetry. She developed her literary voice in English and said abstract painting was the entry point into her native Arabic.
Adnan returned to Beirut, where from 1972 to 1976 she worked as the arts editor for two newspapers. She returned to California in 1979, then spent her later years living between Paris and Beirut.
In 2003, Adnan was named “arguably the most celebrated and accomplished Arab American author writing today” by the academic journal MELUS: Multi-Ethnic Literature of the United States.
Adnan’s most recent honor was in 2020. Her poetry collection “Time,” which is a selection of her work — translated from French by Sarah Riggs — won the Griffin Poetry Prize.
The King Abdulaziz Center for World Culture, or Ithra, earlier this year opened an eponymous exhibition in her honor – “Etel Adnan: Between East and West” – showcasing 41 of her works. The space at Ithra’s gallery is the first solo exhibition of Adnan’s work in Saudi Arabia, running until June 30.
The works on display span from the beginning of Adnan’s artistic career in the late 1950s through to her final creations in 2021, shortly before her death that year aged 96.
Some of the works are on loan from significant international institutions such as the Sharjah Art Foundation, Sfier-Semler Gallery and Sursock Museum. Some are part of private collections.
‘HELP’ written in palm fronds lands rescue for Pacific castaways
- The trio became stranded on Pikelot Atoll, a tiny island in the remote Western Pacific, after their motor-powered skiff malfunctioned
- A US Navy aircraft saw the "help" sign and a ship came later to rescue the stranded trio, all experienced mariners in their 40s
LOS ANGELES: Sometimes all you have to do is ask for “HELP“: That’s what three men stranded on a deserted Pacific island learned earlier this week, writing the message in palm fronds which were spotted by US rescuers.
The trio, all experienced mariners in their 40s, became stranded on a lonely island after setting off from Micronesia’s Polowat Atoll on March 31 in their motor-powered skiff which subsequently experienced damage.
They were reported missing last Saturday by a woman who told the US Coast Guard her three uncles never returned from Pikelot Atoll, a tiny island in the remote Western Pacific.
“In a remarkable testament to their will to be found, the mariners spelled out ‘HELP’ on the beach using palm leaves, a crucial factor in their discovery,” said search and rescue mission coordinator Lt. Chelsea Garcia.
She reported that the trio was discovered Sunday on Pikelot Atoll by a US Navy aircraft.
“This act of ingenuity was pivotal in guiding rescue efforts directly to their location,” she said.
The aircraft crew dropped survival packages, and rescuers one day later dropped a radio which the mariners used to communicate that they were in good health, had access to food and water, and that the motor on their 20-foot (six-meter) skiff was no longer working.
On Tuesday morning a ship rescued the trio and their equipment, returning them to Polowat Atoll, the Coast Guard said.
In August 2020, three Micronesian sailors also stranded on Pikelot were rescued after Australian and US warplanes spotted a giant “SOS” they had scrawled on the beach.
Dining hall with Trojan War decorations uncovered in ancient Roman city of Pompeii
- One fresco depicts Paris and Helen, whose love affair caused the Trojan War, according to classical accounts
- Pompeii and the surrounding countryside was submerged by volcanic ash when Mount Vesuvius exploded in AD 79
ROME: A black-walled dining hall with 2,000-year-old paintings inspired by the Trojan War has been discovered during excavations at the Roman city of Pompeii, authorities said on Thursday.
The size of the room — about 15 meters long and 6 meters wide — the quality of the frescoes and mosaics from the time of Emperor Augustus, and the choice of characters suggest it was used for banquets, Pompeii Archaeological Park said.
“The walls were painted black to prevent the smoke from the oil lamps being seen on the walls,” Gabriel Zuchtriegel, head of the park, said.
“People would meet to dine after sunset, and the flickering light of the lamps had the effect of making the images appear animated, especially after a few glasses of good Campanian wine.”
Pompeii and the surrounding countryside was submerged by volcanic ash when Mount Vesuvius exploded in AD 79, killing thousands of Romans who had no idea they were living beneath one of Europe’s biggest volcanoes.
The site has seen a burst of archaeological activity aimed at halting years of decay and neglect, largely thanks to a 105-million-euro ($112 million) European Union-funded project.
The dominant theme of the newly discovered paintings is heroism and fate.
One fresco depicts Paris and Helen, whose love affair caused the Trojan War, according to classical accounts. Another one shows doomed prophetess Cassandra and the Greco-Roman god Apollo.
According to Greek mythology, Cassandra predicted the Trojan War after receiving the gift of foresight from Apollo, but no-one believed her. This was because of a curse Apollo put upon her for refusing to give herself to him.
Bosnian Formula One fan brings speed dreams to the mountains
- The 36-year-old mechanic bought the car from another racing superfan in the capital Sarajevo last year
- Since purchasing the vehicle, he has been methodically making tweaks to its exterior, while nursing hopes of one day replacing its engine
KLJUC, Bosnia and Herzegovina: Far from the glitzy racetracks where legendary drivers made their mark in the world of Formula One, Himzo Beganovic has turned his dreams of speed into reality along the dirt roads of northwestern Bosnia.
“I always wanted to own a Formula One car, to have it in front of the house, to be able to go for a spin,” Beganovic told AFP, as he tuned up a replica “Ferrari red” race car outside his home near the Bosnian town of Kljuc.
The 36-year-old mechanic bought the car from another racing superfan in the capital Sarajevo last year.
The replica, which took two years to build, remains a ramshackle mock-up, crafted with sheet metal — a far cry from the advanced carbon fiber used in the multimillion-dollar cars of Formula One teams.
Despite Beganovic’s limited means, he still hopes to make his car more efficient, bit by bit.
Since purchasing the vehicle, he has been methodically making tweaks to its exterior, while nursing hopes of one day replacing its engine.
Along with a more powerful motor, Beganovic hopes to install an automatic gearbox and better tires.
“When you drive Formula One, you feel like you are flying. It is not like a car,” he said.
“It is the only one in Bosnia-Herzegovina. There are no others.”
A self-professed lover of “fast driving” and taking “dangerous turns,” Beganovic has been turning heads along Bosnia’s mountain roads where he reaches speeds of up to 200 kilometers per hour (124 miles per hour).
Other times he simply parks the car in a popular area and lets people check it out.
“I sometimes put it on a trailer to take it to other places in the country. People come, photograph it, and ask questions,” he said.
“The feeling is indescribable.”
For Beganovic, there was no question of what color the car would be.
As a longtime fan of seven-time world champion Michael Schumacher, the Ferrari-red paint pays tribute to the driver who won five titles with the famous Italian team.
Since the legendary German champion’s skiing accident in 2013 in the French Alps, Beganovic said he has yet to find another driver that interests him as much.
With Schumacher in mind, he hopes to put an Audi V-8 engine into his car soon.
“When a German engine and Bosnian ingenuity combine, you get an Italian car,” laughed one of Beganovic’s neighbors.
