‘Megafires’ in California, Canada, South Korea and Europe in 2025, but changes to farming slowed spread in parts of Africa
“Devastating” wildfires ripped across the wealthier parts of the world in 2025, a study has found, even as globally, the area ravaged by flames fell.
Catastrophic blazes claimed lives, homes and jobs last year in California, Canada, Europe and South Korea. But the 335m hectares burned was the second-lowest since 2002, the review found, largely owing to the expansion of African farms that have fragmented landscapes and hampered the spread of large savannah fires.

Letting nature take over at a former dairy farm has resulted in a surge of species in just three years
Three years of rewilding on a former dairy farm in east Somerset have led to the number of recorded bird species soaring from 67 to 94, butterfly species rising from 11 to 24 and small mammals growing in number.
Heal Somerset, the first site acquired by the charity Heal Rewilding, has produced a state of nature report mirroring a national survey by environmental charities that has tracked the decline in nature.

Seasonal wardens and netted fences are helping protect the rare ground-nesting birds that arrive each spring on the UK’s shores
On Ross Sands in Northumberland, a little tern has caught sight of a group of people and is sprinting across the beach. “It wants us to follow it,” says Andrew Craggs, senior manager at Lindisfarne national nature reserve. “It’s a diversionary thing – it’s got a scrape and it wants to take us away because it thinks we’re predators.”
Craggs is no predator, and he’s not after the scrape – a small pit the ground-nesting bird has dug into the sand to lay its eggs. He is a guardian of these little birds, as well as more than 3,500 hectares (8,600 acres) of sand dunes, saltmarsh and mudflats that make up this tranquil nature reserve perched on the tip of England’s north-east coast.

A project to measure how reflective paint reduces indoor temperatures is delivering tangible benefits across Africa
The brick house Sylvia shares in a Western Cape township on the outskirts of Cape Town with her three children gets unbearably hot every summer, causing the youngest to cry and her two older children to struggle to concentrate on their homework. Sylvia is not alone, according to a recent report in the Lancet: “In 2024, people in South Africa were exposed to 13 heatwave days, on average. Of these, 10.5 (80%) would not have been expected to occur without climate change.”
But summer is more bearable for the family now that her asbestos roof has been painted with reflective paint.

With no recorded sightings before 1885, noctilucent clouds have been linked to volcanoes, pollution or climate change
As summer arrives in the northern hemisphere, so do the noctilucent clouds – hopefully. These high-altitude formations are as enigmatic as they are beautiful. Their name derives from Latin, meaning “night shining”.
They appear during the summer months and glow with an electric-blue intensity against the darkening western sky. Look for them about half an hour after sunset.

Chelsea, London: I find myself moved by this garden that highlights the ‘edgelands’, those unprotected and modest places where nature can thrive
Parakeets screech and planes rumble overhead, but my attention is on the plants at my feet: the tracery of herb robert, purple nibs of plantain, flailing bramble and bristly nettle. I’m sitting on a boulder in a clearing among hawthorn, privet and silver birch. It feels a quiet space, one you might stumble on in the woods or are drawn to when you feel low, but is in fact at the Chelsea flower show.
The name of this garden is On the Edge for it evokes the edgelands, the fringes of where we live. Unprotected, modest places – not grand landscapes but ones that are close by towns and cities. Designed by Sarah Eberle, the garden marks the centenary of the Campaign to Protect Rural England and the launch of the first interactive map of England’s countryside edges, a gathering of people’s stories and memories about place.

Australia is pioneering a revolution in home renewables and battery use, proving what is possible with the right policies
The timing was rich with symbolism. As intense heatwaves pummelled Europe and Asia, and oil markets around the world leapt and sputtered, the two big chimneys of one of Australia’s largest power stations were being demolished. Meanwhile, the Australian energy minister was holding a media conference to hail a fall of up to 10% in the benchmark electricity price in parts of the country.
Quietly, and with surprisingly little fanfare from the rest of the world, Australia is pioneering a revolution in home renewables and battery use, proving what is possible with the right policies. The country was already one of the global leaders in domestic solar power, with panels on one in three homes. It also remains, however, a major contributor to the climate crisis through its vast fossil fuel exports.But it is batteries that are giving Australia a new burst of speed.

From cliff sides, coastal lookouts, kayaks or boats, people counted every dolphin they saw for at least 15 minutes to aid research into state’s populations
Looking down the barrel of a telephoto lens, Dr Elizabeth Hawkins tells the dolphins circling the research boat to work it for the camera.
“That’s it,” she says, joking to her crew. “Show us some fin. Don’t be shy. How about some tail? Oh that’s good. The camera loves you.”

She had a passion for butterflies and would seek out rare ones, yet this was used against her by violent, money-grabbing husband. Now this pioneering naturalist’s story has been translated to today’s manosphere
‘There’s nothing wrong with having a hobby, or even what you might call in this case a hyperfocus,” psychiatrist Dr Godrick tells Eleanor Glanville in a claustrophobic therapy room.
Outside the Phoenix theatre in Hampshire, a summer heatwave is delivering perfect conditions for butterflies. Inside, a rather darker story is being rehearsed in air-conditioned gloom. Butterfly, a new play, shines a light on one woman’s passion for butterflies and how it is turned against her when she became trapped in an abusive relationship.

Hour by hour, Shahida and her baby are exposed to the full force of the deadly temperatures affecting India’s capital – without reliable access to food, water or healthcare. Here is a day in their lives
Delhi is sweltering through another summer of extreme heat, with top daytime readings consistently reaching 43C and even minimum temperatures hovering around 32.4C (90.3F).
Last week the city endured its warmest May night in 14 years. As government heat alerts follow one after another and people retreat indoors, more than 300,000 individuals living on the city’s streets remain out in the punishing heat.
Shahida dreads the arrival of summer, and this year, she has the additional worry of keeping nine-month-old Jannat safe from the heat
