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.

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.

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.

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.

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.

New research links last month’s disaster to fossil fuel pollution. Supporting disaster-hit countries must be at the centre of climate politics

Following a familiar pattern, coverage of the glacier collapse on the Nepal-Tibet border three weeks ago has subsided with the initial shock. But while the world’s attention has shifted, Nepal remains in the midst of an appalling tragedy. As well as at least 1,300 people who are known to have been killed, more than 5,000 are missing, some of them trapped in tunnels linked to the 13 hydropower plants that were damaged by the floods. On Wednesday four bodies were recovered from one of these tunnels, with searches ongoing. Families of the missing people are desperate for news.

Last week the country’s foreign minister, Shisir Khanal, said that it would ask the UN’s loss and damage fund for $20m (£15m) towards a total rebuilding cost of around $5bn (£3.75bn) – including the replacement of up to 20,000 homes. The first academic study linking the disaster to the climate crisis will now be added to that application. Scientists at Imperial College London, along with international collaborators on the World Weather Attribution project, found that a number of drivers of the glacier fall had been made worse by atmospheric heating. While not the sole cause, fossil fuel pollution was judged to have destabilised the geology of the mountain environment.

Exclusive: PM, who is facing pressure over whether to approve North Sea oil and gasfields, makes strongest comments yet on issue

• British people understand the climate crisis threat. Today I’m empowering them to tackle it

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.

With nearly £30m of funding, I’m giving communities power over local energy. They know the gravity of global heating, and they want to be part of the solution

• Andy Burnham: UK must fully commit to reaching net zero by 2050

On the day I became prime minister, I pledged to bring power to every postcode. Today, we begin to make good on that promise in the most literal sense. With nearly £30m of funding for People’s Power projects, communities across every nation of the UK will soon have the chance to build and control their own clean energy supply.

This investment means villages, towns and cities can harness the natural resources around them with solar panels on libraries, publicly owned windfarms, hydro schemes in their rivers, or whatever else works for them. The purpose is to put money back in people’s pockets while giving them a direct role in tackling the climate crisis.

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.

The US decision to remove limits on coal and gas plant emissions is rooted in a perception of manliness in these industries

You can impress a certain kind of person at a party by reciting the fact that there are more yoga instructors in the US than there are coalminers. In fact, the disparity is greater than this catchy phrasing suggests: there are actually more yoga instructors in the US than there are people employed in the entirety of the coalmining industry, miners and otherwise. It’s not even especially close: about 38,000 people in the US work in coal, according to the Bureau of Labor Statistics, compared to about 100,000 yoga instructors who are registered with the Yoga Alliance, an industry group.

If you looked only at the numbers, you might think a politician would be incentivized to talk about the interests of the yoga industry, about the dignity that yoga jobs give to American families, or about the need to foster growth in the yoga industry, more than they talk about these things for coal; after all, yoga, not coal, is putting food on the table in more American households. But no politician would ever talk about the interests of yoga teachers, or wax poetic about their role in the American dream, the way they do with coal miners; if they did, they’d be laughed out of the room. And we all know why: yoga is thought of as decadent, cosmopolitan and feminine, while coal mining is imagined as hardscrabble, honorable and masculine.

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.

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.

The behaviours we observed could represent grief, but they could also reflect maternal attachment, confusion or instinctive caregiving

It was a tragic sight.

One day last July, a newborn humpback whale calf lay motionless on the seafloor, just a kilometre off Australia’s Gold Coast. The encounter was captured through underwater video.

Critically endangered Bornean orangutans flee forests as staff at Rangkong research station work round the clock to stave off blaze

Wildfires in Indonesia are sweeping through a critical research site for Bornean orangutans and are now threatening a celebrated research camp, home to one of the world’s longest-running studies of wild apes.

In the past few days, the fires have burned within 200 metres of Rangkong research station, a satellite of Cabang Panti research station, which lies about four miles north in Gunung Palung national park.

More than 330,000 sea turtles arrived in southern Mexico in a mass nesting phenomenon known as an ‘arribada’.

The sixth arribada of the season, which began in March, brought thousands of turtles to the beach in less than 48 hours to lay their eggs, according to officials at La Escobilla beach sanctuary in Oaxaca, Mexico.

The olive ridley turtle plays a fundamental role in marine and coastal ecosystems by contributing nutrients to beach-dune systems and regulating populations of jellyfish and sponges, according to Mexico's federal attorney for environmental protection, but the climate crisis is now threatening their survival

As human development and roads increasingly fragment their habitats, a study suggests traffic noise could be altering the animals’ wake-up call

Dawn has broken, and the air is cool and still. It’s at about this time that gibbons usually erupt into song, wa-oo-ing and wa-ing from the highest branches and filling the tree tops with rich melodies. But in this corner of Malaysian forest, bordered by housing and roads, the resident white-handed gibbons are quiet. All that can be heard is the hum of traffic from a nearby highway.

This isn’t a rare occurrence for this group of gibbons, according to research, which found these particular gibbons, named Mambang and Walinong, appeared to be producing far fewer morning songs than others that are not exposed to the same level of traffic noise.

Thirty years after a US ornithologist first sighted a jocotoco antpitta, the foundation he set up to restore biodiversity is a model for conservation globally

I have to confess that I rarely enjoy birding in montane cloud forests. The birds that live in these mountainous, cool and humid habitats are masters of disguise, usually passing themselves off as a leaf or other form of foliage. But if I want to see antpittas – elusive, ground-dwelling birds that rarely show themselves – then I have no choice.

So, on a cool, cloudy morning my guide, Juan Carlos Crespo, Fredy Ramón Castillo, a local ranger, and I are standing on a steep, muddy path close to Tapichalaca Lodge, 2,500 metres above sea level in the eastern Andes, waiting for the jocotoco antpitta to emerge from the undergrowth.

The country is one of just three that still permits commercial whaling, while its government has faced mounting pressure to ban the practice

Iceland will submit a bill in February 2027 which could permanently ban whaling in its waters, a move that would leave Norway and Japan as the only two countries to permit commercial whaling.

Whaling in Iceland has been put under intense scrutiny since a government-commissioned report was published in 2023 that found harpooned whales took two hours to die. The report led to a temporary suspension of the hunt that year.

In the first project of its kind, scientists are trying to answer if the future of Alaska’s streams and tundra may depend not on survival of the fittest but on how species adapt together

On Alaska’s North Slope, scientists tread carefully across clumps of tussock grasses toward a fast-flowing stream draining the imposing Brooks Range of ice and snow. Near Galbraith Creek, they string out a mist net for white-crowned sparrows. The birds have recently arrived from southerly latitudes, intent on feasting on the insects that will soon descend on the tundra like storm clouds.

The Arctic summer is short-lived, and sparrows have only a few weeks to establish territories, find mates, lay eggs and raise their chicks on a steady diet of bugs. From every ensnared bird, the scientists collect blood, feather and faecal samples to see what they are eating and how that changes over the summer.

Anglers will help scientists investigate the porbeagle, tope and blue shark to boost knowledge and conservation

‘We have really cool sharks,” says Dr Lucy Hawkes. She is not referring to animals in the rich coastal waters of South Africa or Mexico, but instead talking about the species that live around Britain. Hawkes, an associate professor at the University of Exeter, is co-leading a new three-year project to investigate the lives of three of England’s most vulnerable shark species.

“I like the porbeagle, which looks like a baby great white shark,” she says. “Surfers could see one and absolutely poop their pants, but they’re not dangerous. It’s amazing that we share the water with some pretty exciting animals.”

The race to study the North Water between Canada and Greenland before it changes has led to a bold plan for an Inuit-run protected area

Electric-blue meltwater sprays up under Terry Noah’s snowmobile as he races across sea ice extending out from Canada’s northernmost public community: Grise Fiord in Nunavut, a hamlet of 144 people closer to Murmansk in Russia than the Canadian city of Toronto. The bay’s cliffs loom higher and higher like stone icebergs as he approaches his destination across the bay.

Noah pulls his sled carefully over a seal’s breathing hole, about the circumference of a basketball. Using a custom-made winch, he lowers a submersible instrument into the sea below the ice.

Ever since the earliest known recording of whale song was made in 1949, researchers have been captivated by the wails, rumbles, clicks, grunts and squeals of their communication. As technology improves, scientists are decoding the intricate patterns that make different species’ vocalisations distinctive. Madeleine Finlay hears from Emma Bryce, a journalist who has spent months investigating human efforts to understand whale song. She explains how this knowledge could help us better protect whales from human-made harms.
