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.

The skies above Makkah will witness the phenomenon of the sun aligning directly over the holy Kaaba on Thursday, at approximately 12:18 PM local time.

Jeddah Astronomy Society Director Eng. Majed Abu Zahra described the phenomenon as a precise astronomical event that attracts wide interest among those seeking to determine the Qibla direction.

He noted that it provides a direct opportunity to verify geographical and astronomical calculations without complex instruments.

During the moment of alignment, shadows cast by vertical objects in Makkah’s surroundings nearly disappear as sunlight falls almost perpendicularly on the surface, he added.

This phenomenon occurs twice annually as the sun moves between the Tropics of Cancer and Capricorn due to Earth’s axial tilt of approximately 23.44 degrees, allowing it to pass over Makkah’s latitude twice a year, once northward and once southward.

Temperatures hit record highs for May in the United Kingdom and France on Monday, as forecasters warned of a prolonged period of extreme heat across Europe throughout the week. 

A so-called "heat dome" of warm air from northern Africa trapped under a high-pressure system over western Europe is behind the high temperatures not usually seen until high summer. 

Temperatures in Spain were expected to peak later this week at 38C, while parts of Italy imposed restrictions on working outdoors. 

"The weather here, it's like a mini version of hell. It's boiling. It's like really hot," said 10-year-old Liza Nizari on a visit to London, where temperatures normally average about 17C or 18C at this time of year. 

Lindy Brand-Daloze, a 66-year-old Australian administrator who has been living in in London for 12 years, said: "It's warm, but it's climate change, isn't it? So, you know, (we have) probably got to get used to this." 

The Met Office weather agency said Monday was the hottest May day on record, with the mercury rising to 33.5C at Heathrow, west of the capital, at 1:00 pm (1200 GMT) -- 1.3C more than the previous benchmark recorded in 1922 and 1944. 

"Records are usually only broken by tenths of a degree -- making this heatwave unprecedented for the time of year," the agency said in a social media post. 

Scientists say human-induced climate change is making extreme weather events like heatwaves, droughts and floods more intense, resulting in temperature records being broken more frequently. 

Met Office meteorologist Greg Dewhurst told AFP the increase in extreme temperatures was "a good indication of climate change in action" and more likely to become "the new norm". 

Climate advisers last week warned the UK government that the country was "built for a climate that no longer exists" and urged it to adapt infrastructure like schools and hospitals for a warming planet. 

In 2022, temperatures in the UK soared above 40C for the first time since records began. 

- Heatwave alert - 

Across the Channel, weather agency Meteo-France put eight areas in the west of France on heatwave alert -- signifying three days and nights of intense heat that are likely to pose a health risk to the population. 

In the northwestern city of Rennes, 74-year-old Daniele Dupont tried to stick to the shade as she walked her dog in 27C on Monday morning. 

"I'm going to close the shutters. I won't be going out this afternoon," she said in the capital of the Brittany region. 

On Sunday, "record high maximum temperatures for the month of May" were felt in at least 10 locations, including the northwestern seaside towns of Lorient and Noirmoutier. 

The capital, Paris, on Saturday notched up its first temperature above 30C of the year, hitting 31.9C. 

Temperatures of up to 35C are expected in Brittany and between 36C and 37C in the south. 

On Sunday, a man died during a 10-kilometer running race in Paris, civil defense services said, while 10 more runners had to be taken to hospital in critical condition after a race in the capital's suburb of Maisons-Alfort, the authorities said. 

In Spain, the State Meteorological Agency (Aemet) warned the "extraordinarily high temperatures for this time of year" will continue across the country all week, except in the Canary Islands, in the Atlantic Ocean, off the northwest coast of Africa. 

"Widespread tropical nights" are also forecast in southwestern Spain from Wednesday, with temperatures peaking from Wednesday to Friday at between 36C and 38C, it wrote on X. 

Farther east, Italy's Lazio region, which includes Rome, on Monday approved rules limiting work in conditions "with prolonged exposure in the sun" between 12:30 pm and 4:00 pm. 

The measures apply, for example, to farms, construction sites and in the logistics sector and apply until September 15. 

Similar rules had been put in place last year but only from May 30. 


How Collecting DNA Samples in the Wild Could Transform Conservation

How Collecting DNA Samples in the Wild Could Transform Conservation

A guide called out to endangered golden monkeys with grunts and clicks to signal he posed no threat, a familiar sound in the mist-covered forests of Rwanda ’s Volcanoes National Park.

Here in one of Africa's most well-known parks, steep ridges and dense vegetation often obscure even the largest mountain gorillas — also endangered — and scientists are turning to new technology to detect and protect them.

Known as environmental DNA, or eDNA, the technology allows researchers to identify species using genetic material like fur or feces left in soil and water. This reduces the impact of human interaction during wildlife surveys that can leave researchers groping through the mist.

The technology, more often used in marine conservation work, was introduced by the African Wildlife Foundation in partnership with the Rwandan government. It aims to develop a list of all species in the country. That will help protect biodiversity that is threatened by climate change and population growth.

“We selected eDNA as a new technology to bring solutions and to complement existing methods used in ecological monitoring,” said the foundation’s country manager for Rwanda, Patrick Nsabimana.

Biodiversity monitoring for decades has relied on camera traps, which operate when animals trigger their sensors, and ranger observations.

But that is a challenge in rugged terrain such as the Virunga mountains that are central to Volcanoes National Park, which covers part of Rwanda, Uganda and Congo. Insecurity in the border area also can limit ranger movement.

Nsabimana said eDNA is a cost-effective monitoring approach in large ecosystems such as Virunga. Samples are taken from locations like downstream ponds that are likely to have traces of animals on higher ground. Then they are tested.

“With one sample, you can detect multiple species, mammals, birds, amphibians and many others,” said Deogratias Tuyisingize, a Rwanda-based biodiversity researcher with the Dian Fossey Gorilla Fund that is also involved in the project.

He said a combination of traditional methods and new technology is needed to ensure all species are monitored. Because of steep ravines and mountainsides, “we are sure we were missing some species."

Meanwhile, having a better sense of where endangered species are could help in patrolling against poachers, people with the project said.

The ability to generate a broad snapshot of biodiversity is critical for conservation, especially as Rwanda expands some of its national parks by rehabilitating previously agricultural land.

“We can see how species are colonizing these sites over time,” Tuyisingize said.

That allows conservationists to measure success by the return of rare or threatened species, and offers early warnings of invasive species.

But the eDNA technology is not without limitations. It cannot reliably estimate how many animals are present in an ecosystem. DNA can linger long after a species has left.

Being able to process samples in Rwanda is also a challenge, as the project's initial ones had to be sent to Europe for analysis.

Joshua Newton, who conducted research on eDNA for Curtin University’s Trace and Environmental DNA Laboratory, said challenges also include having cold storage to preserve DNA samples and ensuring samples are not contaminated.

Data gaps are another issue. Africa has relatively limited genetic reference libraries, despite decades of conservation work on the continent, making it harder to match DNA samples to known species.

Most genetic reference libraries come from Europe and America, said James Munyawera, a lab specialist with the Dian Fossey Gorilla Fund.

Researchers are now building region-specific databases.

The project in Volcanoes National Park has also begun training residents of local communities, along with rangers, to participate in monitoring efforts by collecting samples.
