More heavy rain is forecast for Brazil’s already flooded Rio Grande do Sul state, where many of those remaining are poor people with limited ability to move to less dangerous areas.

More than 15 centimeters (nearly 6 inches) of rain could fall over the weekend and will probably worsen flooding, according to the latest bulletin from Brazil’s national meteorology institute. It said there is also a high likelihood that winds will intensify and water levels rise in the Patos lagoon next to the state capital, Porto Alegre, and the surrounding area.

As of Saturday morning, heavy rains were falling in northern Rio Grande do Sul, while Porto Alegre and the southern part of the state were receiving drizzle.

Carlos Sampaio, 62, lives in a low-income community next to soccer club Gremio’s stadium in Porto Alegre. His two-story home doubles as a sports bar.

Even though the first floor is flooded, he said he won't leave, partly out of fear of looters in his high-crime neighborhood, where police carry assault rifles as they patrol its flooded streets. But Sampaio also has nowhere else to go, he told The Associated Press.

“I am analyzing how safe I am, and I know that my belongings aren't safe at all,” Sampaio said. “As long as I can fight for what is mine, within my abilities to not leave myself exposed, I will fight.”

At least 136 people have died in the floods since they began last week, and 125 more are missing, local authorities said Friday. The number of people displaced from their homes due to the torrential rains has surpassed 400,000, of whom 70,000 are sheltering in gyms, schools and other temporary locations.

“I came here on Monday — lost my apartment to the flood," Matheus Vicari, a 32-year-old Uber driver, said inside a shelter where he is staying with his young son. "I don’t spent a lot of time here. I try to be out to think about something else.”

Some residents of Rio Grande do Sul state have found sanctuary at second homes, including Alexandra Zanela, who co-owns a content agency in Porto Alegre.

Zanela and her partner volunteered when the floods began, but chose to move out after frequent electricity and water cuts. She headed to the beachfront city of Capao da Canoa — so far unaffected by flooding — where her partner’s family owns a summer home.

“We took a ride with my sister-in-law, took our two cats, my mother and a friend of hers and came here safely. We left the Porto Alegre chaos,” Zanela, 42, told the AP by phone. “It is very clear that those who have the privilege to leave are in a much safer position, and those living in the poorer areas of Porto Alegre have no option.”

In Brazil, the poor often live in houses built from less resilient materials such as wood and in unregulated areas more vulnerable to damage from extreme weather, such as low-lying areas or on steep hillsides.

“We cannot say that the worst is over,” Rio Grande do Sul Gov. Eduardo Leite said on social media Friday. The day before, he estimated that 19 billion reais ($3.7 billion) will be needed to rebuild the state.

The scale of devastation may be most comparable to Hurricane Katrina that hit New Orleans, Louisiana, in 2005, Sergio Vale, chief economist at MB Associates, wrote in a note Friday.

Rio Grande do Sul has the sixth highest GDP per capita among Brazil's 26 states and the federal district, according to the national statistics institute. Many of the statel's inhabitants descend from Italian and German immigrants.

“In the popular imagination, the population of Rio Grande do Sul is seen as white and well-off, but this is not the reality,” said Marília Closs, a researcher at the CIPO Platform, a climate think tank. “It’s very important to dispel this fiction, because it’s constructed with a political objective” to erase Black and poor residents, she said.

In Canoas, one of the hardest-hit cities in the state, Paulo Cezar Wolf’s small wooden house has been fully submerged, along with all his belongings. A truck driver, the Black man now lives in the back of a loaned truck with six of his neighbors, who all cook, eat and sleep there.

Wolf, 54, has considered leaving the rural region, where he has lived since childhood, but has nowhere else to go and doesn’t want to leave behind his four adult children.

“It is too late for someone like me to move somewhere else,” Wolf said, wearing a donated sweatshirt as he stood on a highway.

The meteorology institute predicts the arrival of a mass of cold and dry air will reduce the chance of rain beginning Monday. But it also means temperatures are set to drop sharply, to around freezing by Wednesday. That makes hypothermia a concern for those who are wet and lacking electricity.

Celebrities, among them supermodel Gisele Bündchen and pop star Anitta, have been sharing links and information about where and how to donate to help flood victims. Churches, businesses, schools and ordinary citizens around the country have been rallying to provide support.

The UN refugee agency is distributing blankets and mattresses. It is sending additional items, such as emergency shelters, kitchen sets, blankets, solar lamps and hygiene kits, from its stockpiles in northern Brazil and elsewhere in the region.

On Thursday, Brazil’s federal government announced a package of 50.9 billion reais ($10 billion) for employees, beneficiaries of social programs, the state and municipalities, companies and rural producers in Rio Grande do Sul.

The same day, the Brazilian air force parachuted over two tons of food and water to areas that are inaccessible due to blocked roads. The navy has sent three vessels to help those affected, among them the Atlantic Multipurpose Aircraft Ship, which it said is considered the largest warship in Latin America. It arrived on the state's coast Saturday.

The US has sent $20,000 for personal hygiene kits and cleaning supplies and will be providing an additional $100,000 in humanitarian assistance through existing regional programs, White House national security spokesman John Kirby said Friday.

Weather across South America is affected by the El Niño climate phenomenon, a naturally occurring event that periodically warms surface waters in the equatorial Pacific. In Brazil, El Niño has historically caused droughts in the north and intense rainfall in the south, and this year the effects have been particularly severe.

Scientists say extreme weather is happening more frequently due to climate change, caused by the burning of fossil fuels that emit planet-warming greenhouse gas emissions, and overwhelmingly agree the world needs to drastically cut the burning of coal, oil and gas to limit global warming.

But there is a need for social policy responses, too, said Natalie Unterstell, president of Talanoa Institute, a Rio de Janeiro-based climate policy think tank.

“Providing an effective response to climate change in Brazil requires us to combat inequalities,” Unterstell said.

An ungainly barrel of a shark cruising languidly over a barren seabed far too deep for the sun’s rays to illuminate was an unexpected sight.

Many experts had thought sharks didn’t exist in the frigid waters of Antarctica before this sleeper shark lumbered warily and briefly into the spotlight of a video camera, researcher Alan Jamieson said this week. The shark, filmed in January 2025, was a substantial specimen with an estimated length of between 3 and 4 meters (10 and 13 feet).

“We went down there not expecting to see sharks because there’s a general rule of thumb that you don’t get sharks in Antarctica,” Jamieson said.

“And it’s not even a little one either. It’s a hunk of a shark. These things are tanks,” he added.

The camera operated by the Minderoo-UWA Deep-Sea Research Centre, which investigates life in the deepest parts of the world’s oceans, was positioned off the South Shetland Islands near the Antarctic Peninsula. That is well inside the boundaries of the Antarctic Ocean, also known as the Southern Ocean, which is defined as below the 60-degree south latitude line.

The center on Wednesday gave The Associated Press permission to publish the images.
The shark was 490 meters (1,608 feet) deep where the water temperature was a near-freezing 1.27 degrees Celsius (34.29 degrees Fahrenheit).

A skate appears in frame motionless on the seabed and seemingly unperturbed by the passing shark. The skate, a shark relative that looks like a stingray, was no surprise since scientists already knew their range extended that far south.

Jamieson, who is the founding director of the University of Western Australia-based research center, said he could find no record of another shark found in the Antarctic Ocean.

Peter Kyne, a Charles Darwin University conservation biologist independent of the research center, agreed that a shark had never before been recorded so far south.

Climate change and warming oceans could potentially be driving sharks to the Southern Hemisphere’s colder waters, but there was limited data on range changes near Antarctica because of the region’s remoteness, Kyne said.

The slow-moving sleeper sharks could have long been in Antarctica without anyone noticing, he said.

“This is great. The shark was in the right place, the camera was in the right place and they got this great footage,” Kyne said. “It’s quite significant.”

The sleeper shark population in the Antarctic Ocean was likely sparse and difficult for humans to detect, Jamieson said.

The photographed shark was maintaining a depth of around 500 meters (1,640 feet) along a seabed that sloped into much deeper water. The shark maintained that depth because that was the warmest layer of several water layers stacked upon each other to the surface, Jamieson said.

The Antarctic Ocean is heavily layered, or stratified, to a depth of around 1,000 meters (3,280 feet) because of conflicting properties including colder, denser water from below not readily mixing with fresh water running off melting ice from above.

Jamieson expects other Antarctic sharks live at the same depth, feeding on the carcasses of whales, giant squids and other marine creatures that die and sink to the bottom.

There are few research cameras positioned at that specific depth in Antarctic waters.

Those that are can only operate during the Southern Hemisphere summer months, from December through February.

“The other 75% of the year, no one’s looking at all. And so this is why, I think, we occasionally come across these surprises,” Jamieson said.

A 17th century Swedish Navy shipwreck buried underwater in central Stockholm for 400 years has suddenly become visible due to unusually low Baltic Sea levels.

The wooden planks of the ship's well-preserved hull have since early February been peeking out above the surface of the water off the island of Kastellholmen, providing a clear picture of its skeleton.

"We have a shipwreck here, which was sunk on purpose by the Swedish Navy," Jim Hansson, a marine archeologist at Stockholm's Vrak - Museum of Wrecks, told AFP.

Hansson said experts believe that after serving in the navy, the ship was sunk around 1640 to use as a foundation for a new bridge to the island of Kastellholmen.

Archeologists have yet to identify the exact ship, as it is one of five similar wrecks lined up in the same area to form the bridge, all dating from the late 16th and early 17th centuries.

"This is a solution, instead of using new wood you can use the hull itself, which is oak" to build the bridge, Hansson said.

"We don't have shipworm here in the Baltic that eats the wood, so it lasts, as you see, for 400 years," he said, standing in front of the wreck.

Parts of the ship had already broken the surface in 2013, but never before has it been as visible as it is now, as the waters of the Baltic Sea reach their lowest level in about 100 years, according to the archaeologist.

"There has been a really long period of high pressure here around our area in the Nordics. So the water from the Baltic has been pushed out to the North Sea and the Atlantic," Hansson explained.

A research program dubbed "the Lost Navy" is underway to identify and precisely date the large number of Swedish naval shipwrecks lying on the bottom of the Baltic.


China Has Slashed Air Pollution, but the ‘War’ Isn’t Over

China Has Slashed Air Pollution, but the ‘War’ Isn’t Over

Fifteen years ago, Beijing's Liangma riverbanks would have been smog-choked and deserted in winter, but these days they are dotted with families and exercising pensioners most mornings.

The turnaround is the result of a years-long campaign that threw China's state power behind policies like moving factories and electrifying vehicles, to improve some of the world's worst air quality.

Pollution levels in many Chinese cities still top the World Health Organization's (WHO) limits, but they have fallen dramatically since the "airpocalypse" days of the past.

"It used to be really bad," said Zhao, 83, soaking up the sun by the river with friends.

"Back then when there was smog, I wouldn't come out," she told AFP, declining to give her full name.

These days though, the air is "very fresh".

Since 2013, levels of PM2.5 -- small particulate that can enter the lungs and bloodstream -- have fallen 69.8 percent, Beijing municipality said in January.

Particulate pollution fell 41 percent nationwide in the decade from 2014, and average life expectancy has increased 1.8 years, according to the University of Chicago's Air Quality Life Index (AQLI).

China's rapid development and heavy coal use saw air quality decline dramatically by the 2000s, especially when cold winter weather trapped pollutants close to the ground.

There were early attempts to tackle the issue, including installing desulphurization technology at coal power plants, while factory shutdowns and traffic control improved the air quality for events like the 2008 Olympics.

But the impact was short-lived, and the problem worsened.

- Action plan -

Public awareness grew, heightened by factors like the US embassy in Beijing making monitoring data public.

By 2013, several international schools had installed giant inflatable domes around sport facilities to protect students.

That year, multiple episodes of prolonged haze shrouded Chinese cities, with one in October bringing northeastern Harbin to a standstill for days as PM2.5 levels hit 40 times the WHO's then-recommended standard.

The phrase "I'm holding your hand, but I can't see your face" took off online.

Later that year, an eight-year-old became the country's youngest lung cancer patient, with doctors directly blaming pollution.

As concerns mounted, China's ruling Communist Party released a ten-point action plan, declaring "a war against pollution".

It led to expanded monitoring, improved factory technology and the closure or relocation of coal plants and mines.

In big cities, vehicles were restricted and the groundwork was laid for widespread electrification.

For the first time, "quantitative air quality improvement goals for key regions within a clear time limit" were set, a 2016 study noted.

These targets were "the most important measure", said Bluetech Clean Air Alliance director Tonny Xie, whose non-profit worked with the government on the plan.

"At that time, there were a lot of debates about whether we can achieve it, because (they were) very ambitious," he told AFP.

The policy targeted several key regions, where PM2.5 levels fell rapidly between 2013 and 2017, and the approach was expanded nationwide afterwards.

"Everybody, I think, would agree that this is a miracle that was achieved in China," Xie said.

China's success is "entirely" responsible for a decline in global pollution since 2014, AQLI said last summer.

- 'Low-hanging fruits' gone -

Still, in much of China the air remains dangerous to breathe by WHO standards.

This winter, Chinese cities, including financial hub Shanghai, were regularly among the world's twenty most polluted on monitoring site IQAir.

Linda Li, a running coach who has lived in both Beijing and Shanghai, said air quality has improved, but she still loses up to seven running days to pollution in a good month.

A top environment official last year said China aimed to "basically eliminate severe air pollution by 2025", but the government did not respond when AFP asked if that goal had been met.

Official 2025 data found nationwide average PM2.5 concentrations decreased 4.4 percent on-year.

Eighty-eight percent of days featured "good" air quality.

However, China's current definition of "good" is PM2.5 levels of under 35 micrograms per cubic meter, significantly higher than the WHO's recommended five micrograms.

China wants to tighten the standard to 25 by 2035.

The last five years have also seen pollution reduction slow.

The "low-hanging fruits" are gone, said Chengcheng Qiu from the Center for Research on Energy and Clean Air (CREA).

Qiu's research suggests pollution is shifting west as heavy industry relocates to regions like Xinjiang, and that some cities in China have seen double-digit percentage increases in PM2.5 in the last five years.

"They can't just stop all industrial production. They need to find cleaner ways to produce the output," Qiu said.

There is hope for that, given China's status as a renewable energy powerhouse, with coal generation falling in 2025.

"Cleaner air ultimately rests on one clear direction," said Qiu.

"Move beyond fossil fuels and let clean energy power the next stage of development."
