Cornell Lab for Ornithology plans data linkup between app and population monitoring on eBird platform

The Merlin bird ID app will allow users to feed real-time bird identifications into one of the world’s biggest citizen-science biodiversity projects in an update it is hoped will aid conservation of at-risk birds.

Since 2021, the free Merlin app, created by the Cornell Lab for Ornithology, has used machine learning to provide an almost instantaneous sound-identification service for birdsong, along with an image for each bird identified. In future, the detections of bird species recorded by people will be automatically collected on the global online database eBird, which contains more than 2bn bird observation records.

Shifting demands and political ideology have left the industry vulnerable to global competition from cheap Chinese cars

Earlier this month, an intriguing new Detroit-based electric vehicle startup hit the market – Slate Auto, a Jeff Bezos-backed venture offering something US buyers rarely see these days – a pick up truck billed as “affordable”.

Its base price is $24,950, making it one of the lowest-cost autos in the US market and close to half the price of the average new vehicle. But as the US contends with sharply rising auto costs, even Slate may be getting left behind in the global electric vehicle (EV) transition. The global EV industry is entering a golden age powered by cheap Chinese cars that can be bought for as little as $10,000.

Witek Morek is closely inspecting an old brick-and-flint wall on the Cambridgeshire campus of the Wellcome Sanger Institute.

“We are going to use a very advanced tool designed by bioengineers and evolved over millions of years – the human hand – and grab some moss, and put it in an envelope,” he says.

Hitchin, Hertfordshire: The broad-bodied chaser is often the first to arrive at a new pond, and sure enough, I spot an exuvia clinging to a leaf blade

The hole in the nest box on our house wall is all mouth. A sparrow chick on the cusp of fledging has thrust its head out, beak open, displaying an orange gape ringed with a creamy-yellow flange. It’s an unmissable prompt for the parents: Insert Invertebrates Here.

I’m watching the spuggies from behind the pond, where I’m perfectly positioned to see the aftermath of another emergence. At the top of a bur-reed, the hollow legs of a dragonfly exuvia (the shed larval casing) grip the leaf blade, while a split in the cuticle shows where the adult has pushed through its exoskeleton.

There is a rising stink around rubbish removal in Australia. Councils around the country are looking for ways to divert more organic waste away from landfill.

Australians generate about 14.6m tonnes of organic waste each year – mostly garden clippings, food scraps and timber. About half of it is collected from households in kerbside bins.

Public health authority says 2,025 excess deaths probably an underestimate and that it expects toll to rise further

The number of deaths recorded in France surged by nearly 30% during the hottest week of the record-breaking heatwave that scorched much of Europe last month, the public health authority has said, adding that it expected the toll to rise further.

Public Health France said on Friday there had been “an increase of 29.1%, corresponding to 2,025 additional deaths compared with the previous week”. It said the figure was probably an underestimate and “mortality will rise further”.

Every year, millions of visitors from across the globe visit Jamaica to enjoy its gorgeous beaches, fuelling a multibillion dollar tourism industry. But, in recent years, its picture-perfect coastlines have become a battleground for access after successive governments privatised its shorelines to support the country’s thriving all-inclusive hotel industry.

The complex row, which has seen protesters clashing with police and campaigners tearing down barriers around privatised properties, is now playing out in the country’s courts. We take a closer look at each side’s case, and what’s at stake.

European heatwave is worst ever and impossible without climate crisis, scientists say

Guardian recreates audio landscape of past filled by loud morning symphony before 73m wild birds were lost

Imagine a deafening abundance of birdsong so loud it wakes your children at dawn; the chirrup of house sparrows, the chattering of starlings, the melody of the wren, and the clear high-pitched flute of blackbirds saturating the garden, reverberating around your local park, dominating your neighbourhood from early morning to evening twilight.

So loud is the song of the thrush that the naturalist and ornithologist WH Hudson wrote in 1919 that he was grateful when observing one that it was perched on a tree at a distance from his home, “so that when I woke at half past three or four o’clock, the shrill indefatigable voice came in at the open window, softened by distance and washed by the dewy atmosphere to greater purity”.

In one area 76% of fishing boats were followed, with baby dolphins learning the technique from their parents

Bottlenose dolphins in the Adriatic are increasingly following trawlers to scavenge for food, with baby dolphins learning the technique from their parents, a study has found.

“These days the easiest way to find [bottlenose dolphins] is to look for trawlers,” said Giovanni Bearzi, a co-author of the study and the president of Dolphin Biology and Conservation in Italy. “Many of them are followed by the dolphins that go to forage and scavenge in their wake.

Nearly 3,000 people have been evacuated in southern France as the country swelters through a record-breaking heatwave. The fire started at a campsite, destroying dozens of mobile homes before spreading to the marina area, where thick, toxic smoke blanketed boats. The fire broke out in the town of Sainte-Marie-la-Mer and spread to Canet-en-Roussillon on Thursday [• This gallery’s headline and subheading were amended on 3 July 2026; an earlier version referred to south-western France]

Participant-led YPS scheme creates green projects while providing summer jobs in country with high youth unemployment

Oona Verveld and Clara Vikberg have just secured their first paid summer jobs. While their peers are mostly limited to entry-level positions in retail or fast-food restaurants, the 18-year-olds are some of the first among their generation to have landed a new type of role: young planetary stewards.

“Someone came up with the simple idea that, since young people clearly need jobs, why not create them?” says My Sellberg, the project manager and programme lead for regenerative development at Upplandsbygd, a non-profit based north of Stockholm. “The strongest objective was to inspire hope for the future among our young residents.”

Despite a deadly heatwave sweeping through Europe, the US president’s ineptness has created reason for optimism on the climate crisis

Two real-life climate-themed movies are playing in parallel across the globe. They are about the world today, but they are also a snapshot of the future. The first is a slow-building horror story; the second, a feelgood summer hit. Both are worth watching.

Horror films are suddenly box-office gold, so let’s start there. The World Health Organisation says the extreme, record-breaking heatwave blanketing Europe has killed more than 1,300 people. But everyone knows that number will end up a dramatic understatement.

An eight-month expedition will set off soon from Norway on a mission to find new species before the climate crisis and pollution changes the northern ocean for ever

Six scientists and six crew will travel next month to Kirkenes, a remote Arctic town in Norway near the Russian border, to begin an odyssey to one of the most inhospitable, inaccessible and least-studied regions on Earth. There, they will climb onboard a futuristic, floating laboratory – the French-built Tara polar station.

They will enter a harsh and isolating environment: months of complete darkness and temperatures as low as -50C (-58F). Arriving in Norway on 14 August, they will await good conditions and an icebreaker to open a route for them before setting off on an eight-month voyage, overwintering through long, intense polar nights onboard a 26-metre-long, 16-metre-wide vessel built to be frozen into the pack ice, which will drift slowly over the north pole to Greenland.

Poaching and wildfires have driven the country’s jaguar population to a critical level, and until now even rescued animals faced life in captivity

A tentative paw emerged from a steel cage on to the sandy riverbed deep in the Bolivian rainforest. Then, another. Slowly, the female jaguar looked right, left and right again, as if waiting to cross a busy road. Then, muscles stiff from the long journey, it strolled away and disappeared into the undergrowth.

Yaguara had been in captivity since August 2024, after being orphaned as an eight-month-old cub amid Bolivia’s worst recorded wildfire season. As the fires raged, burning more than 10% of the country’s surface area, authorities handed the cub over to a team of veterinarians from the Comunidad Inti Wara Yassi (CIWY), a wild-animal rescue centre.

The United States of America is … so many things, horrific and magnificent, good and evil, promising and cursed

The United States of America is a truck that has driven into a ditch. The United States of America is a program that has been hacked. The United States of America is … so many things, horrific and magnificent, good and evil, promising and cursed, as it approaches its quarter-millennium mark. I say it as though the US was one thing, but it is a thousand things.

It is the masked ICE agent shooting Renee Good as she stood up for immigrants, but it is also Good herself and the immigrants, and the streets of Minneapolis and their Dakota and Ojibwe Indigenous past – and present and future. The US before 1865 was slaveowners, but it was also the enslaved and the abolitionists.

The class politics of extreme heat are very real and very dangerous – but that doesn’t stop the billionaire press from peddling its agenda

Every time you think the idiocy has hit rock bottom, it discovers a new level. It turns out there’s an even deeper hole you can dig for yourself than climate-science denial: heat-stress denial. Across the billionaire press last week, columnists and leader writers minimised the health impacts of the heatwave, particularly in schools. Expect more of this next week, when temperatures are forecast to soar again.

An editorial in the Telegraph (which represents the newspaper’s view) titled “Hot weather alarmism treats the public like children” maintained that “unlike in the seventies, when people were largely trusted to look after themselves, officialdom now feels the need to lecture the public about the risks of hot weather at every opportunity”. Extreme heat warnings are issued and weather maps are “painted in an alarming red”. Outrageous! Instead of issuing warnings, the government should just trust people to “take the appropriate precautions”. We should all “learn to live” with it. Quite right too: whatever happened to the bulldog spirit of ignorance and needless death? Cricket, warm beer, excess mortality: these are the markers of national character.

Bollards, cones, fences and LandCruisers stand little chance against a 1,000kg giant known as 'Neil the seal'. The five-year-old elephant seal is already a local legend and has once again taken up residence in towns in southern Tasmania. He's bypassing barricades, he's crushing fences, he's lying in roads

A warm start to winter is part of a global trend of extreme and unseasonable temperatures caused by global heating

Many parts of Australia have already broken early winter maximum and minimum temperature records.

In southern Australia, Sydney and Melbourne had their warmest-ever starts to winter. Daily observations show both cities experienced above-average June temperatures almost every day of the month.

Cornwall's housing crisis is forcing young people to live in vans. As second homes and short-term holiday lets drive up house prices, a growing number are turning to van life to stay in the place they love. The Guardian meets young people who say their van brings them freedom but also uncertainty, as they struggle to find water, safe places to park and secure a future

Some details in this film have been changed for safety reasons

With tourists buying up property and landlords opting for lucrative Airbnb rentals, young Cornish people are turning to old campervans to provide a roof over their heads

Skye has a thick duvet in the van she calls home in Cornwall. In winter, the 25-year-old goes to bed in several layers of clothes and is grateful for the extra warmth of her cat. She parks up late, often in car parks well away from beaches, and never stays more than one night in case local people get angry and bang on her windows. This is van life. It can be a very different world from the tourist dream.

“Some winters I’ve had ice on the inside of my van windows, and the door handles frozen shut with me inside,” says Skye, a special educational needs teaching assistant. One year her diesel air heater packed up, and she spent the whole winter feeling cold. “That was genuinely awful.” Even with the heater on in the evening, those nights and early mornings when the temperature drops below zero are tough. “I often get dressed in bed,” she says. “You just have to adjust.”

Wildlife photographer Mohammed Almuntasir had no idea what he had found until scientists started to get in touch

When wildlife photographer Mohammed Almuntasir uploaded 18 seconds of footage to YouTube, he thought little more about the small, pale cat seen digging a hollow in the sand in the remote dunes of south-west Libya.

The video, however, posted in 2017, turned out to be the first material evidence that the sand cat (Felis margarita), the world’s only felid adapted to true desert conditions, existed in the country.

The cost of the traditional takeaway has doubled since 2019, and more outlets are trying to tempt customers with cheaper options such as coley, pollack and hake

In late April, visitors to Harbour Lights in Falmouth, Cornwall, may have raised an eyebrow. The fish and chip shop was in the midst of a “cod-free week”, its owners having removed cod from its menu entirely.

It was the second time owner Pete Fraser had undertaken the experiment, 15 years after the first. He also removed cod from his shops in Penzance and Helston, replacing it with coley, pollack, hake and hoki. The result was very different. “Some of the feedback we had, which certainly wasn’t what we got when we ran it years ago, is ‘Can you repeat this?’ Before, it was like, ‘Have you guys lost your head’?”

The island’s biggest tree – named Heaven Sword of the Da’an River – is a carbon-storing behemoth hosting whole neighbourhoods of wildlife. But this and other giant trees are under threat

The higher you climb up the gigantic, millennia-old trees of Taiwan’s forests, the more layers of habitat and life emerge. On the forest floor, ferns thrive in the moist shade. Flying squirrels and owls sleep inside the hollow tree trunks. Yellow bell-shaped rhododendron flowers spring from the lower tree canopy. Higher still, dense lichen spread. Up in cloud-drenched branches, a rare, hardy orchid, Bulbophyllum ciliisepalum, can be spotted.

“In one tree, every species has their preferred location,” says Dr Rebecca Hsu, assistant researcher at the Taiwan Forestry Research Institute. “Every metre the temperature, the wind, the sun, the light is different.”

The reconstruction of the vaquita, whose numbers barely reach double figures in the wild, is designed to help research and conservation efforts

Scientists have created a digital reconstruction of the world’s most endangered marine mammal, preserving its anatomy in three dimensions to aid research and conservation efforts as the species teeters on the brink of extinction.

The project digitised the skeleton of a female vaquita, a small porpoise found only in Mexico’s northern Gulf of California, using a combination of medical imaging, ultra-high-resolution micro CT scans and photography.
