‘Forcing a reckoning’: How Asia is preparing for a ‘supersized’ El Niño
From Sri Lanka to South Korea, governments are preparing for droughts, wildfires, typhoons and floods – with climate plans facing their biggest challenge to date
Asian governments are rushing preparations for the most severe El Niño weather event on record, with hundreds of millions of people bracing for multiple crises at once as extreme heat, heavy rain and food shortages hit the region.
Fuelled by exceptionally warm ocean conditions across the tropical Pacific – and developing alongside the human-driven climate crisis – El Niño is virtually guaranteed to grow to a very strong intensity towards the end of this year and into 2027.

Improved air quality linked to better mental development in toddlers, study finds
Long-term research in New York shows efforts to reduce air pollution associated with higher cognitive test scores
Improvements in air pollution are leading to brighter, smarter toddlers, according to a new study from Columbia University in New York.
For more than two decades, Prof Frederica Perera and a team from the Columbia Center for Children’s Environmental Health measured the air pollution exposure of pregnant women and the development of their children in the disadvantaged communities of northern Manhattan and the South Bronx. More than 1,100 children were assessed when they were one, two and three years old.

The world’s rivers are at breaking point. Can we save them before it is too late?
In this week’s newsletter: As the Guardian launches a year-long project, Our Rivers, we take stock of the issues facing waterways around the world
The nicknames of the world’s biggest rivers give a sense of how we feel about them: “the great river”, “the river that swallows all rivers”, “Mother Ganga” and “Old father Thames”. They feed and water us, and many other animal species. They carry our trade but also give us cool relief on a hot day. They’re nerve endings, elders and sources of comfort, but also of awe and respect.
And yet many of the world’s rivers are suffering, hit by multiple environmental challenges. A new report out today from the World Meteorological Organization finds that rivers across the world experienced one of the driest years in more than three decades during 2025.

MPs urge ministers to break off Thames Water talks with US hedge funds
Efra committee calls for emergency legislation enabling government to take public control of the company
Andy Burnham is under further pressure to take control of ailing Thames Water from a cross-party group of MPs who are calling for ministers to break off talks with the US hedge funds who are effectively running the company.
Adding their voices to demands that the prime minister takes public control of the company, which has debts of £20bn and is being controlled by a group of 100 hedge funds and distressed-debt investors, the MPs said in a report that ministers should consider emergency legislation to take control of its financial affairs to stabilise the company.

Country diary: Dinner time for the buzzard family is not a dignified affair | Kate Blincoe
Caistor St Edmund, Norfolk: We have three breeding pairs on the farm, and one in particular has been a source of fascination and amusement
I’m out on the farm most days, but I miss so much. It took a few days to notice a mother mallard with her late brood of 12 ducklings until they were all dabbling in a yard puddle. Dad sees more than me. He told me of the lazy adult buzzard that waited in a tree, then dive-bombed a peregrine that had caught a pigeon. The peregrine dropped its prey, which the buzzard then delivered to a hay bale already strewn with feathers. A pair of juvenile buzzards swiftly followed, ready for a meal.
Later, Dad placed the trail camera at the bale. The young buzzards were soon back in position with yet another dead pigeon. The footage tells a story that many parents will recognise after the long summer holidays.

Andy Burnham: UK must fully commit to reaching net zero by 2050
Exclusive: PM, who is facing pressure over whether to approve North Sea oil and gasfields, makes strongest comments yet on issue
The UK must fully commit to reaching net zero by 2050, Andy Burnham has argued in his strongest comments yet on the issue, saying it is no longer possible for Britons to believe they are not already affected by a changing climate.
Writing for the Guardian about new plans for a mass of community-led local green energy projects, the prime minister said the UK must “believe in itself”, and set out his determination to reach net zero targets, which have been rejected by the Conservatives and Reform UK.

Fifty billion trees by 2030: how Ethiopia is recruiting citizens across the country to plant, plant, plant
After losing much of its forests in recent decades, the country’s people have led the way in planting saplings across the country as part of the government’s Green Legacy Initiative
When Halima Kedir first began planting trees, she was met with scepticism and even mockery. “My neighbours discouraged me,” she recalls, sitting on a wooden chair in her garden, which is lush with the trees and fruits she has planted – banana, olive and grevillea among them.
“They thought I was striving for nothing, but with time, many are realising that trees can be part of the solution to our problems as a way to fight climate change and food insecurity,” she says.

‘It’s beautiful when it’s clean’: the Argentine neighbourhood saving a contaminated river
Sewage, dog carcasses and industrial waste clog Argentina’s second most-polluted river. Meet the activists cleaning it up
Twenty-three years ago, María Monges looked around her flooded neighbourhood and knew something had to be done.
Founded in 1998 in Buenos Aires province’s San Martín district, the community of Costa Esperanza sits on the banks of the Reconquista, Argentina’s second most-polluted river and owes its name to the fictional location of a hit Argentine youth telenovela of the time, Verano del 98. But the real place is very different from the idyllic coastal city where the protagonists of Argentina’s answer to Dawson’s Creek met their first loves or sang around bonfires.

‘Like a Disney movie’: Three wild dog brothers make Africa’s longest journey
As three siblings came of age and had to leave their pack, scientists tracked the dogs’ perilous 2,500-mile odyssey to find their own territory
It sounds like a Disney movie: three wild dogs, all brothers, on an epic journey to find a home of their own after their family tells them to leave. They dodge cars and hunters in search of a new life, navigating bushmeat snares and the hostility of a human-dominated landscape until they find a new haven on the African savannah.
But this is exactly what happened in Zambia last year, when three endangered African wild dogs made the longest-ever recorded single journey of any mammal from the continent. The brothers travelled more than 2,500 miles (4,100km) over eight months in their “dispersal” – when a young dog comes of age and must establish new territory to find a mate and start a family of their own.

Jednostavan test stolice mogao bi pomoći u otkrivanju raka debelog crijeva i gušterače
Rak probavnog sustava te bilijarnog trakta i gušterače često je teško otkriti u ranoj fazi, što stvara potrebu za praktičnim, neinvazivnim pristupima ranom otkrivanju i procjeni rizika. Crijevni mikrobiom pokazao se kao potencijalni izvor biomarkera za rak, nudeći praktične mogućnosti za neinvazivno testiranje jer se promjene u mikrobiomu mogu procijeniti analizom uzoraka stolice.

Tekuća biopsija mogla bi otkriti rak gušterače u najranijoj fazi
Jedan od razloga zašto je rak gušterače i dalje tako smrtonosan jest taj što se obično otkriva kasno, nakon što se već proširio. No, sada je nova studija pokazala da je tekuća biopsija, nazvana PANXEON, vrlo osjetljiva u otkrivanju raka gušterače prvog i drugog stadija te da ima nisku stopu lažno pozitivnih rezultata. Eksperimentalni test također je omogućio prepoznavanje displazije visokog stupnja – predkanceroznog stanja gušterače – čime se potencijalno omogućuje intervencija prije nego što se rak razvije.

Može li svakodnevna čaša soka od naranče doprinijeti zdravlju srca?
Prema novom kliničkom ispitivanju, prirodni spojevi u soku od naranče regulirali su gene uključene u kontrolu funkcije kardiovaskularnog sustava i krvnih žila. Znanstvenici su utvrdili da su muškarci koji su tijekom šest tjedana svakodnevno pili 330 ml 100-postotnog soka od naranče apsorbirali bioaktivne spojeve iz agruma, uključujući hesperidin, te pokazali promjene u aktivnosti gena povezanih sa zdravljem krvnih žila.

Osobe s ADHD-om izložene većem riziku od gastrointestinalnih problema
Analiza 23 studije pokazala je da je poremećaj pozornosti s hiperaktivnošću (ADHD) povezan s gotovo 50 posto većom učestalošću gastrointestinalnih simptoma u usporedbi s osobama bez ADHD-a. Poveznica je bila još izraženija kod specifičnih problema: gotovo dvostruko veći rizik od zatvora, 58 posto veća učestalost sindroma iritabilnog crijeva te više od četiri puta veći rizik od enkopreze (gubitka kontrole nad pražnjenjem crijeva).

Onečišćenje zraka povezano s povećanim rizikom od glaukoma i sive mrene
Danas postoje čvrsti dokazi da je izloženost onečišćenom zraku štetna za srce i pluća. Mnogo se manje zna o utjecaju onečišćenja zraka na oči, iako su one izravno izložene. Znanstvenici ističu da njihovi nalazi podupiru potrebu za strožim standardima kvalitete zraka i mjerama za smanjenje onečišćenja.

Izloženost svjetlu tijekom noći može promijeniti strukturu i funkciju srca
Izloženost svjetlu tijekom noći povezana je sa značajnim i potencijalno štetnim promjenama u strukturi i funkciji srca, tvrdi nova studija. Inače, prethodne opservacijske studije povezale su izloženost svjetlu noću s povećanim rizikom od kardiovaskularnih bolesti, no malo se znalo o povezanim promjenama u strukturi i funkciji srca.
