On a tiny Italian island, scientists conducted a radical experiment to see if the bees were causing their wild cousins to decline
Off the coast of Tuscany is a tiny island in the shape of a crescent moon. An hour from mainland Italy, Giannutri has just two beaches for boats to dock. In summer, hundreds of tourists flock there, hiking to the red and white lighthouse on its southern tip before diving into the clear waters. In winter, its population dwindles to 10. The island’s rocky ridges are coated with thickets of rosemary and juniper, and in warmer months the air is sweetened by flowers and the gentle hum of bees.
“Residents are people who like fishing, or being alone, or who have retired. Everyone has their story,” says Leonardo Dapporto, associate professor at the University of Florence.

The people of Johnshaven have watched the sea edge closer and closer. Preserving the path is key to protecting their community
When Charis Duthie moved to Johnshaven with her husband in 1984, she could cycle along the coastal path out of the village. Now, she meets a dead end where the sea has snatched the land and is instead greeted with a big red warning sign of what is to come: Danger Coastal Erosion.
“You can see gardens that were there and now they’re gone,” she says.
Johnshaven, on Scotland’s North Sea coast, will attract more visitors if it has a well maintained coastal path

Increasingly erratic water cycle is creating food scarcity, rising prices, conflict and migration, says UN agency
Only a third of the world’s river basins experienced normal conditions last year as the climate crisis drove extremes of drought and flood, sometimes both in the same region.
The increasingly erratic water cycle is creating big problems for societies and governments and causing billions of dollars in damage, scientists warned.

St Dominic, Tamar Valley: So far in early autumn, an abundance of ash keys and plump acorns – and the apple and pear trees are heavily laden
At last, Atlantic weather has set in, bringing much-needed rain to green the hard-grazed turf and fields of cut hay and silage. A few late swallows swoop between hedgerows along sky-reflecting Summers Lane, and dart beneath the gate of the adjoining pony-trodden field. Before the rain, a battalion of 50 swallows gathered on wires by Corneale farm, perhaps in anticipation of the journey home.
After the unusually early harvest of cereals (completed by mid-August), the earth beneath the stubble is softened; maize puts on yet more growth and should provide lots of fodder when gathered next month. Livestock farms are self-sufficient in winter feed, but some straw for bedding has been bought from upcountry, costing up to £120 per tonne.

Researchers from Imperial College London say 16,500 deaths caused by hot weather brought on by greenhouse gases
Human-made global heating caused two in every three heat deaths in Europe during this year’s scorching summer, an early analysis of mortality in 854 big cities has found.
Epidemiologists and climate scientists attributed 16,500 out of 24,400 heat deaths from June to August to the extra hot weather brought on by greenhouse gases.

Since our 2024 climate pledge, there has been a global pushback against green progress. This update reflects the urgent and growing challenges facing our planet – and how the Guardian is more focused than ever on exposing the causes of the climate crisis
In the past three weeks, more than 50,000 Guardian readers have supported our annual environment support campaign. If you believe in the power of independent journalism, please consider joining them today
The Guardian has long been at the forefront of agenda-setting climate journalism, and in a news cycle dominated by autocrats and war, we refuse to let the health of the planet slip out of sight.
2024 was the hottest year on record, driving the annual global temperature above the internationally agreed 1.5C target for the first time
Winter temperatures at the north polereached more than 20C above the 1991-2020 average in early 2025, crossing the threshold for ice to melt
The planet’s remaining carbon budget to meet the international target of 1.5C has just two years left at the current rate of emissions
Humans are driving biodiversity loss among all species across the planet, according to the largest syntheses of the human impacts on biodiversity ever conducted worldwide
Tipping points – in the Amazon, Antarctic, coral reefs and more – could cause fundamental parts of the Earth’s system to change dramatically, irreversibly and with devastating effects. We asked the experts about the latest science – and how it makes them feel
Published our annual company emissions data, explaining what drives our emissions and where they have risen and fallen
Created a digital course, as part of an initiative by the Sustainable Journalism Partnership, sharing examples from experts across the Guardian of how to embed sustainability into journalism and media commercial operations
Contributed our time and knowledge to working groups in the advertising industry that are working on better ways to measure the emissions impact of advertising

Accommodation costs at climate summit in Belem are pricing out some developing countries and media outlets
The United Nations has urged its staff to limit attendance at the Cop30 climate summit in Brazil in November due to high accommodation prices, while government delegations are still scrambling to find rooms within their budgets.
The move comes as delegations grow increasingly concerned about the cost of accommodation in the coastal Amazon city of Belem hosting Cop30. Brazil said it was working to increase the number of available hotel beds, but soaring prices for accommodation have stoked calls from some governments to relocate the conference, which Brazilian officials have rejected.

The warmest summer on record has brought a premature autumn – which could leave little food for overwintering birds
According to the Met Office, autumn in the UK began on 1 September, yet in the hedgerows around my home there have been signs of the season’s arrival for many weeks now, after the warmest summer on record.
Hawthorn trees, which usually produce their crimson berries from mid-September onwards, have been festooned since the second week of August; while blackthorns are drooping under the weight of huge, ripe, purple sloes.

DIY expert Jaharn Quinn has spent 20 years upcycling homewares. She shares where to look and what to bring when hunting for pre-loved pieces
I have always loved thrifting and upcycling. There’s no greater feeling than discovering a hidden gem at a thrift shop and upcycling it into something new, especially when you save hundreds – sometimes thousands – of dollars.
I love flipping through interior magazines, poring over gorgeous images on Pinterest and scrolling through home tours on social media.
Compile your thrifting inventory. This should include the items you are especially looking for, such as a bedside table or a chest of drawers. It’s inevitable that you’ll get sidetracked – which is half the fun – but a list helps you focus when you start to feel overwhelmed, which sometimes happens.
Always carry cash. It makes it easier to bargain.
Pack plenty of blankets or towels in your car. These will protect the pieces you find and keep them cushioned from moving around in your vehicle too much.
Pack a toolkit including antibacterial wipesto wipe down secondhand furniture, removing the dust and dirt to see what’s underneath; measuring tape to see what will fit in your car and home; a notebook filled with ideas, house plans and measurements plus a pencil to jot more down; paint swatches to check for colours that can easily be integrated into your home; and a screwdriver set in case you need to take furniture apart to fit it into your car.

Thousands of dodos could return within a decade according to Colossal Biosciences, a ‘de-extinction’ company – but experts warn of ‘moral hazard’
Since its demise in the 17th century, the dodo has long been synonymous with extinction. But thousands of dodos could soon again populate Mauritius, the species’ former home, according to a “de-extinction” company that has announced a major breakthrough in its quest to resurrect the flightless bird.
Colossal Biosciences said on Wednesday it has succeeded in growing pigeon primordial germ cells, precursor cells to sperm and eggs, for the first time. This is a “pivotal step” in bringing back the dodo, which was a type of pigeon, for the first time in more than 300 years, according to Colossal.
