The story of one of the world’s oldest icebergs is nearly at an end, after a breathtaking 40-year journey that has captivated scientists.

The iceberg, known as A23a, was once the largest on Earth, covering an area more than twice the size of Greater London, according to BBC.

But after a path full of twists and turns, A23a has melted, fractured and spectacularly disintegrated over the past year.

Now, far from the icy seas of Antarctica, what’s left of A23a is being eaten away by warmer waters. It’s in its death throes, not expected to last more than a matter of weeks.

All icebergs melt eventually, but scientists have been looking at how it's disintegrated for clues about how other parts of Antarctica might respond as the climate changes.

“It’s been an extraordinary journey,” said Prof Mike Meredith of the British Antarctic Survey in Cambridge. “But it is on its last legs now.”

This is the story of A23a’s final months.

But first we have to go back to 1986. That year, a nuclear reactor exploded at the Chernobyl power plant in what is now northern Ukraine, Gary Lineker won the golden boot at the Fifa World Cup in Mexico, and Whitney Houston received her first Grammy award.

Away from the world’s gaze, the Filchner Ice Shelf - a massive floating tongue of ice extending from the Antarctic continent and into the Weddell Sea - was changing dramatically. One of the icebergs to break off - or calve - was A23a, then about 4,000 sq km.

It soon became anchored in the muds of the Weddell Sea, where it remained stuck for more than 30 years. It wasn’t until 2020 that scientists noticed signs that A23a was on the move again.

While it’s likely icebergs have lived longer in the Earth’s distant past, A23a is thought to be the oldest iceberg in the world today, at least among those picked up by satellites and tracked by scientists.

“Its journey is really pretty impressive, just for sheer longevity,” said Dr Christopher Shuman, a retired scientist formerly with the University of Maryland, Baltimore County, in the US. He likens tracking its path to watching a TV drama “where you don't know what you're going to see next.”

As A23a moves across the vast South Atlantic Ocean, it can be hard to grasp its scale - but if you could drop it into the English Channel its size would be much more striking.

At the start of 2025 - even after 39 years - A23a was still a collosus. It would have almost stretched between the Isle of Wight and Normandy in France. Now, it wouldn’t even reach halfway from Dover to Calais.

“To watch it be so stable for so long, and then just disintegrate over one year, has been fascinating,” said Dr Catherine Walker of the Woods Hole Oceanographic Institution in the US, who was born the same year as A23a.

Over the past two weeks A23a has been carried by ocean currents in a near-complete clockwise loop. This could be its final dance.

Recent satellite images suggest further hydrofracturing of what was left of it - “tantalizing evidence of sudden disintegration”, according to Prof Adrian Luckman of Swansea University.

While other icebergs have travelled further in the past, A23a is the furthest north of any Antarctic iceberg being tracked by scientists today. It’s closer to the equator than London.

The prolonged exposure to sea warmth means the berg’s remains will inevitably fragment and eventually melt away, even though the Southern Hemisphere winter is on the horizon.

By 5 March, A23a had shrunk to approximately 180 square km, although estimates can vary slightly.

Once it gets to roughly 70 square km, scientists will stop tracking it. That moment’s not far away, according to Luckman.

“All traces will probably have disappeared in a matter of weeks now, at most,” Luckman said.

A Sumatran orangutan has been filmed for the first time crossing a man-made canopy bridge constructed to help the endangered animals bypass a tarred road on the Indonesian island, an NGO said Sunday.

Conservation group Tangguh Hutan Khatulistiwa, in partnership with the UK-based charity Sumatra Orangutan Society (SOS) and local authorities, built five canopy bridges in the North Sumatra province in 2024, after a road that serves as a lifeline for remote communities had been expanded, cutting through the rainforest.

The first Sumatran orangutan has now been caught on camera using one of the hanging bridges, SOS said in a statement sent to AFP Sunday.

While other species including gibbons and long-tailed macaques have also been spotted crossing there, "this is a world first for Sumatran orangutans," it added.

The bridge's use by the orangutan was a "huge milestone for conservation", SOS chief executive Helen Buckland said.

"These canopy bridges demonstrate that human development and wildlife don't have to be at odds. Sometimes, the simplest solutions are the most effective," Buckland added.

The road is an important social and economic link for communities in Sumatra's Pakpak Bharat district.

But it has also split a population of some 350 orangutans, SOS said.

Erwin Alamsyah Siregar, executive director at Tangguh Hutan Khatulistiwa, said that habitat fragmentation was "one of the greatest challenges in contemporary conservation".

He said he hoped canopy bridges would become a "standard feature" of infrastructure planning across the region.

The International Union for Conservation of Nature classifies Sumatran orangutans, endemic to the island of Sumatra, as critically endangered.

Their decline is blamed on habitat loss and fragmentation as well as illegal hunting.

In the wild, orangutans are found only on Sumatra and the nearby island of Borneo, which is shared between Indonesia, Malaysia and Brunei.

Japan has deployed 1,400 firefighters and dozens of Self-Defense Force personnel to battle mountain blazes that have been raging in the north for five days and threaten to reach homes in the picturesque coastal town of Otsuchi, officials said on Sunday.

Fanned by dry, windy weather, two more wildfires broke out elsewhere in the north on Sunday - one in Kitakata city and the other in Nagaoka, potentially stretching firefighting resources thin as local authorities send personnel to neighbouring areas.

The area burned by the Otsuchi fires reached 1,373 hectares (3,393 acres) as of Sunday morning, up 7% from a day earlier.

RESIDENTIAL AREAS AT RISK

The fires threaten residential districts of Otsuchi on the Pacific Coast - a town that lost nearly a 10th of its population in one of Japan's worst disasters, the March 2011 earthquake and tsunami.

Authorities expanded the scope of evacuation orders to 1,558 households or 3,257 residents by Sunday evening, roughly a third of Otsuchi's population.

"Although the Self-Defense Forces are fighting the fires from the sky (with helicopters), the dry weather and winds are helping the fires expand," Otsuchi Mayor Kozo Hirano told a press conference.

Some residents used hoses to spray water onto their houses and surrounding foliage, hoping to keep the flames at bay.

"I am prepared to evacuate by my car at any time. Fire won't be able to catch up to us since it does not move as fast as a tsunami," said resident Shigeki Fujiwara, 67.

Flames up in the mountain were visible from his home, and while his family has already been evacuated, he said he had chosen to stay behind because he was worried about the house.

FORECAST FOR RAIN

The only casualty to date has been one minor injury suffered when a person fell at an evacuation centre, Japan's Fire and Disaster Management Agency said on its website.

Rain is expected in some parts of Iwate prefecture's southern coastal region, where Otsuchi is located, according to the Japan Meteorological Agency.

The cause of the Otsuchi fires is not clear and is under investigation.

While Japan has experienced relatively few wildfires compared with other parts of the world, climate change has increased their frequency, especially as the early spring months before the humid rainy season have been hot, dry and with winds that can whip up flames.

Inside the World’s Largest Art Heist When over $500M of Paintings Were Stolen from a Boston Museum

Inside the World’s Largest Art Heist When over $500M of Paintings Were Stolen from a Boston Museum

For decades, the 1990 theft of 13 artworks from the Isabella Stewart Gardner Museum — now valued at more than $500 million — has remained unsolved.

It remains the largest art theft in history — far surpassing more recent museum thefts, including a daylight heist at the Louvre that involved far fewer works and was resolved more quickly. In 2013, the FBI said it knew who was responsible for the Boston museum heist but declined to name them, fueling speculation that persists today.

A former FBI agent who led the investigation for more than two decades is now offering the first detailed account of how investigators reached that conclusion — and publicly identifying the men he believes were involved. In a new book, Geoff Kelly traces how the artworks moved through criminal networks, where violence took the lives of key suspects and witnesses, and challenges long-circulating theories by revisiting key details.

The irony at the center is that Gardner’s intention was for the museum to remain frozen in time, stipulating in her will that nothing in the Venetian palazzo-inspired building would be changed after her death. Gardner, who lived in the museum and died there in 1924, intended for the paintings, sculptures and architectural fragments to remain exactly as she had arranged.

The empty gilded frames of the missing paintings still hang in the museum today — silent witnesses to what was taken.

The art heist Early on March 18, 1990, as Boston wound down from St. Patrick’s Day celebrations, two men dressed as police officers arrived at the museum and convinced a security guard to let them in, violating protocol.

The men handcuffed the guards in the basement and made their way to the museum’s Dutch Room, where they cut Vermeer’s “The Concert” and Rembrandt’s “Christ in the Storm on the Sea of Galilee" from their frames, also taking works by Degas and Manet.

They also took a Napoleonic eagle finial — a decorative metal piece of comparatively little value that investigators later found puzzling — and the museum’s security videotapes.

The museum offered a $5 million reward that they then doubled a decade later for information leading to the recovery of the works.

Boston-area network of criminals Some tips pointed to the Irish Republican Army and to Boston mob figures, including notorious crime boss Whitey Bulger.

Kelly followed one lead to France, where he watched through binoculars as FBI agents, posing as wealthy intermediaries, lounged on a yacht — drinking champagne and eating strawberries — in an effort to draw out suspected Corsican mob figures.

Closer to home, agents searched houses across New England, relying heavily on informants. A triple murderer known as “Meatball” who was terminally ill secretly recorded conversations with suspected associates in hopes of earning money for his family.

But none of the tips led to the paintings.

Violence complicates matters In the decades since the robbery, several people believed to have ties to the heist were killed, and another died under suspicious circumstances.

Robert “Bobby” Donati, a Boston mob associate long suspected in the case, was found stabbed to death in 1991, his body left in the trunk of a car after his home had been ransacked.

Years earlier, Donati has visited the Gardner with another known art thief, Myles Connor, to scope it out for a robbery and said that if he ever took the museum’s Napoleonic finial, it would be his “calling card.” Years later, a jeweler told investigators Donati tried to sell a finial from the Isabella Stewart Gardner Museum but backed off, saying it was “too hot.”

A separate line of evidence centered on George Reissfelder, who investigators believe owned the getaway car.

Kelly tracked down Reissfelder’s brother, a retired military officer who had initially not believed his brother was involved. He broke down after being shown Manet’s “Chez Tortoni,” saying he recognized it as a painting he himself hung above his brother’s bed.

Reissfelder later died under suspicious circumstances. When investigators searched his home, the painting was gone.

Both men had ties to TRC Auto Electric, a Dorchester shop linked to Charles “Chuck” Merlino’s crew.

Investigation with limited resources Though investigators believed they knew who was responsible, they had a difficult time finding definitive proof.

In its early stages, the FBI assigned a single agent to the case, which Kelly said slowed progress.

“You have to keep in mind when you’re talking about investigations, they come down to dollars and cents,” Kelly said. It was “like pulling teeth” to secure resources. At the time, federal investigators in Boston were heavily focused on violent crime, drug trafficking and organized crime cases.

Kelly said a decision to release surveillance footage despite investigators’ objections became a lasting distraction. With no usable video from the night of the robbery, prosecutors released footage from the night before that showed a museum employee entering the building after his car broke down. Kelly said he objected to the theory that the employee was casing the museum, since that possibility had already been reviewed and dismissed. The footage fueled years of misplaced suspicion, since the man was later determined not to be involved.

Theories about an inside job at the museum Among the questions that linger is whether it was an inside job.

In photos from that night, a museum guard is seen handcuffed in the basement, his head wrapped in duct tape.

Investigators noted that shortly before the robbery, the guard opened a door against policy — one that faced the area where the thieves were later seen waiting — a move investigators considered highly unusual and suspicious.

“It’s the immutable laws of time and space,” Kelly said. “I think that there was enough information back then that he could have been charged. Would it be enough to convict him? I don’t know.”

By the time investigators examined those questions more closely, Kelly said, the statute of limitations had expired, leaving them with little leverage to compel cooperation.

The museum guard, Rick Abath, denied any involvement in the theft. He died in 2024.

The artworks that disappeared Kelly personifies the missing artworks and describes them as “perfect fugitives.”

“They don’t go to the doctor. They don’t get stopped for speeding. They don’t leave fingerprints,” he said. “They can just disappear.”

Unlike human fugitives, he said, artworks can also be copied.

Over the years, that has meant chasing down false leads — including paintings spotted in a Reno antique market, hanging in private homes and even one that appeared in an episode of the TV show “Monk.”

Because the works are so recognizable, it's nearly impossible to sell them publicly.

“Stealing the artwork from the museum, that’s the easy part,” Kelly said. “Profiting from it, that’s the difficult part.”

He imagines the paintings will surface one day — outliving those who carried out the heist.

“I have no doubt they still exist,” he said
