Following Hurricane Katrina in 2005, a number of dolphins were found dead from a fatal skin disease near New Orleans, Louisiana's biggest city. The same incident has been observed in numerous parts of the world, but the exact cause of this mysterious disease has never been known.

Today, 15 years later, a new study carried out by researchers at the Marine Mammal Centre in Sausalito, California, and the Murdoch University in Australia, suggested it might be caused by the environmental changes in the dolphins' marine habitat that are linked to climate change. The study was published in the latest issue of the Scientific Reports journal.

In an analysis that identified a link between climate conditions and the death of dolphins from the skin disease, researchers found one common factor among all the death cases that occurred in the US and in other regions of the world like Australia: they happened after the wake of severe storms such as hurricanes and cyclones, in which a massive volume of freshwater rain falls onto land, with subsequent run-off finding its way into rivers and coastal waters.

According to the study, the danger of such sudden deluge events is that they rapidly diminish the salinity of the saltwater that coastal dolphins live in, producing hypo-saline conditions that can persist for weeks or months, as environmental monitoring data from the Australian sites show. Dolphins can tolerate hypo-saline conditions, but only for a short while, with prolonged exposure to freshwater resulting in a range of changes to the animals' skin and blood chemistry, producing dermatitis, lesions, and other physiological stresses, accompanied by opportunistic colonization by algae, fungi, and bacteria.

"The breaks in the skin cause the dolphin to lose vital ions and proteins from their bodies. So when all of that is oozing out of them, the fresh water then rushes in, which causes swellings and ulcers," said lead author Nahiid Stephens from Murdoch University in Australia in a report published Wednesday on the Science Alert website.

The lesions are equivalent to third-degree burns in humans, a horrific injury that can very rapidly result in death. It kills them because it causes electrolyte disruptions in their blood stream and they ultimately end up with organ failure, he added.

South ‌Korea's Unification Ministry said on Tuesday that passenger train services between Pyongyang and Beijing are set to resume this week, marking the end of a six-year suspension caused by the COVID-19 pandemic.

The resumption restores a critical transport link between North Korea and its primary economic ally, after ‌years of ‌strict border closures that began ‌in ⁠early 2020.

China's state ⁠railway told the Yonhap News Agency that the Pyongyang–Beijing train will begin the round-trip service on March 12, operating four times a week.

Only the last two carriages will ⁠initially carry passengers, mainly diplomats or ‌others on ‌official business, with ticket sales to the general ‌public possible if seats are ‌available, Yonhap quoted a railway official as saying.

North Korea remains closed to most foreign tourism, with limited exceptions largely for ‌Russian tour groups under restricted arrangements, according to travel agencies organizing trips ⁠to ⁠the country.

Before the pandemic, Chinese visitors made up the largest share of foreign tourists to North Korea, the agencies said.

Tour organizers said on Monday that North Korea had cancelled next month's Pyongyang Marathon for unspecified reasons. The race is one of the few events that has been open to international participants in the isolated state.

Former Fukushima Worker Devotes Life to Abandoned Pets

Not far from the Fukushima nuclear disaster site, former plant worker Toru Akama tends to dozens of pets abandoned after the catastrophe 15 years ago, work he sees as part of his quest for redemption.

Meows and barks break the silence of the countryside, once an evacuation zone, as the 63-year-old brings food to the animals left behind when their owners fled the triple disaster of March 11, 2011: earthquake, tsunami, and nuclear accident.

"It's because of this plant, where we worked for years, that these animals ended up like this," Akama told AFP at his home in northern Japan, surrounded by cats.

"They should have been able to go on living their lives as pets, but because of this accident they were abandoned.

"I felt it was my duty to protect them," he said.

Akama will never forget what he saw in the wake of the disaster, caused by Japan's strongest earthquake on record.

The tsunami it unleashed killed or left missing 18,500 people, and a wall of water crashed into the Fukushima nuclear plant on the northeast coast causing a devastating meltdown.

A day later, residents were ordered to evacuate and an unbroken line of cars formed on the national highway that runs past Akama's house.

"Then the dogs started wandering in search of something to eat -- least those that weren't chained up," he recalled.

"There was no one left, just my wife and me handing out food."

-'Outrage'-

Akama then began taking the animals into his home: first 40 dogs, then 50.

A decade and a half later, he has found adoptive families for more than 1,000 animals and continues to take in new pets who have been abandoned for other reasons.

He says he has "felt outrage" at the pet owners, who have sometimes left their animals in front of his house.

Some "are remorseful, but others simply do it because the animals have become a nuisance", he said.

In difficult moments, "of course... people's priority is human beings, but animals are living beings too, members of the family. It's as if people were abandoning their own children".

After the nuclear disaster, some residents had to flee by bus, and animals were not allowed aboard.

"There were elderly people in tears, asking if someone could take their pet," he recalled.

A month after the disaster Akama also had to leave, but he returned every day for his work at the plant and to look after his charges.

"Because they had known hunger, I absolutely wanted to give them a good life. Sometimes we went without ourselves in order to buy them quality food," he said.

-They 'watch over me'-

Over the past 15 years, Akama says he has spent almost all of the compensation he received after the plant accident on the animals, and he continues to cover most of their care and food costs.

"I don't have time to deal with collections or crowdfunding campaigns," he explained, although he has received some donations.

Akama's days are structured around cleaning the cages where new arrivals spend their first days, feeding, walking the dogs, and taking in new residents, leaving him little respite.

"It never stops. To be honest, I feel like my old job was easier," he said.

"But thanks to them I've never fallen ill: they force me to stay active. Maybe it's their way of thanking me, of watching over me in their own way."

At first, he kept the ashes of the deceased animals in his house, but he eventually had to build a grave outside to hold the remains of around 30 dogs and even more cats, beneath the inscription "rest in peace".

Akama's brother took over his subcontracting business for the plant, allowing him to devote himself full time to the 47 cats and seven dogs with whom he currently shares his life.

"If I'm still able to keep going today, it's because I carry within me the distress these animals experienced. That's what keeps me going."

He would nevertheless like to find a successor.

"That's my biggest concern right now, because I too am starting to get older," he said.

"But I'd like to keep going like this until the end."

The world logged its fifth hottest February on record, with western Europe drenched by extreme rainfall and widespread flooding, the European Union's climate monitor said on Tuesday.

Global temperatures last month were 1.49C above pre-industrial times, defined as the 1850-1900 period before large-scale fossil fuel use drove climate change.

Temperatures and precipitation varied widely in Europe.

The average temperature in Europe was among the three coldest in the past 14 years at -0.07C.

But western, southern and southeast Europe experienced above-average temperatures, according to the Copernicus Climate Change Service.

Colder conditions were experienced in northwest Russia, Baltic countries, Finland and its Scandinavian neighbors.

"Wet and dry conditions across the continent showed a pronounced contrast: much of western and southern Europe was wetter than average, whereas the rest of the continent... was mostly drier than average," the service said in its monthly report.

The United States, northeast Canada, the Middle East, Central Asia and east Antarctica had warmer-than-average temperatures.

- Need for global action -

Sea surface temperatures were the second highest for the month of February.

In the Arctic, the average sea ice extent was at its third lowest level for the month at five percent below average.

In the Antarctic, the monthly sea ice extent was close to average for February -- a "sharp contrast to the much below-average" levels observed over the past four years, Copernicus said.

"The extreme events of February 2026 highlight the growing impacts of climate change and the pressing need for global action," said Samantha Burgess, strategic lead for climate at the European Center for Medium-Range Weather Forecasts, which operates Copernicus.

"Europe experienced stark temperature contrasts," Burgess said.

"Exceptional atmospheric rivers -- narrow bands of very moist air -- brought record rainfall and widespread flooding to western and southern Europe," she said.

Human-driven climate change intensified torrential downpours that killed dozens and forced thousands of people from their homes across Spain, Portugal and Morocco between January and February, according to the World Weather Attribution (WWA) network of climate scientists.
