Meteorologists say mean average temperature of 16.5C was made 130 times more likely by climate crisis
This year’s summer was the UK’s hottest on record, according to provisional data, and the Met Office said the season’s mean temperature was made 130 times more likely by the climate crisis.
Record-breaking and back-to-back heatwaves have scorched much of Europe. In England, temperatures peaked at 38.1C (100.1F) at Kew Gardens in London on 13 August, and June had already been confirmed as the country’s hottest since records began in 1884. Scientists have said these heatwaves are only possible because of the climate crisis driven by burning fossil fuels.

It has been hard not to despair while watching the ruinous floods swallow parts of Nepal, and harder, still knowing that the agony compounds each passing day for dozens of Indian families whose members remain unaccounted for.
Social media is awash with desperate pleas, photos and details of the young and old, men and women, from Mumbai to Kolkata, posted by families searching for traces of life. The disaster unfolded when a melting glacier slammed into the valley below, unleashing a deadly cascade of rock and ice down the Bhote Kashi River, which flows from Tibet into Nepal.

High winds associated with El Niño could cause widespread mortality among tree species already weakened by a prolonged period of extreme heat and drought, experts have warned.
This summer much of Europe has been scorched by a series of record-breaking climate crisis-induced heatwaves. The impact is notable across much of England’s countryside, where once green land has turned brown, and many trees are undergoing “early autumn” – wilting and losing their leaves early – to cope with extreme heat.

Households in Great Britain’s cloudiest regions could still save more than £400 a year on their energy bills by installing rooftop solar panels, research has found.
Rising wholesale energy prices mean the potential savings from a home solar panel system have climbed in recent years, as the cost of installation has continued to fall, leading to increased demand.

This week the Euro summer comes to an end – and so does a certain type of posting on Instagram.
Waiting at the bus stop in the grey winter dawn, a slanting rain soaking your trouser leg, you can warm yourself by scrolling your feed and seeing pictures of Australians enjoying a Euro summer. There it is again – azure Greek coves, plates of barbecued sardines, the yachts rented by the hour, and selfies on the balcony of some Paris Airbnb, drinking wine in the long, blue night.

You may not have felt it, but the earth beneath our feet is getting twitchier, and global heating is to blame. As temperatures surge and climate breakdown accelerates, interactions between climate and geology are becoming ever more apparent – as marked by last week’s horrific events in Nepal and Tibet. We still have a bit of a blind spot when it comes to the idea that a changing climate can impact what scientists call the geosphere, but the evidence has long been incontestable.
In 2021, a similar deluge ripped through a series of mountain valleys in the Indian Himalayan state of Uttarakhand, severely damaging two hydroelectric power plants and taking about 200 lives. In August 2025, a colossal landslide in an Alaskan fjord created a 500-metre-high wave in an area frequented by cruise ships. A few months earlier, the collapse of part of a glacier in Switzerland’s Valais canton caused a debris-laden torrent that destroyed and buried most of the already evacuated village of Blatten.

Turkmenistan has started plugging the mega-leaks of methane that spew from its ageing oil and gas facilities, the latest UN data shows, in a move hailed as a breakthrough.
Methane, also called natural or fossil gas, is a potent greenhouse gas. It traps 80 times more heat than carbon dioxide and causes 25% of global heating today. Stopping leaks can be quick and cheap and, because methane breaks down in the atmosphere far quicker than CO2, this has a rapid impact, with some experts calling it the climate “emergency brake”.

An army official calls out a name. A young woman stands, two pieces of identification in her hands. She fills out a form, takes another and moves to the back of the hospital to give a vial of blood.
With so many people killed by Nepal’s floods, and hundreds of bodies being buried because the morgues are full, there is now a push to identify victims through DNA. The woman, Prakrit Gurung, 19, is hoping her DNA will be linked to her mother’s body. Her father’s has been found – her brother recognised his picture on a wall outside the hospital.

In the community of La Lima in Guatemala, Elda Dinora Ramírez, 58, looks towards a small well at the back of her home. Dusty wooden planks lie across the opening, concealing the faint gleam of water far below. “The well is drying up again,” she says.
Ramírez’s home lies less than a mile from Era Dorada – a goldmining project acquired by the Canadian multinational Aura Minerals in January 2025. After years of inactivity, the project was reactivated this year when the Guatemalan government granted Aura a construction licence.

All it took to turn the murky, heavily polluted waters of South Africa’s Stiebeuel River into a resource clean enough for irrigating a community’s vegetable plots was a collection of stones, heat-treated wood and sand.
Without chemicals and using renewable energy, researchers from the University of Cape Town are cleaning 36,000 litres of water, polluted by sewage, chemicals, and traces of drugs and medication, every day to make it usable for growing food in a fast-expanding informal settlement along the course of the river.

For millennia, the high peaks of the Himalayas were held together by an invisible, frozen cement – permafrost and glacial ice that bound ancient rock into seemingly unshakable fortresses. But as the planet continues to warm, this alpine glue is liquefying.
The glacial collapse and deluge in Nepal and Tibet was not a freak weather event; it was the structural failure of a mountain itself, nature’s latest commentary on the deadly consequences of human-caused planetary warming. And it was the exclamation point on a summer of extremes, illustrating with a sole unnatural disaster the apocalyptic future that lies in store if we fail to take dramatic climate action.

Anthony Albanese has been clear that he wants a set of national standards to ensure datacentre growth accelerates Australia’s push to renewables and keeps a lid on power prices. At the centre of his desired policies was a “BYO power” requirement – a condition that all new datacentres would be powered by 100% renewable electricity.
But last week these aims collided with the Queensland and Northern Territory governments’ desire to rely on their state-owned gas and coal power stations to power datacentres.
Continue reading...Richer countries might have more resources to deal with catastrophe, but this problem grips the entire planet, however much leaders may want to deny it
Climate breakdown is happening on one Earth, but two different worlds. In one, its impacts increasingly encroach on everyday life; longer periods of discomfort and shorter periods of sharp pain. Endless, hotter summers, and within them sudden wildfires, evacuations, homes burned to cinders in a matter of hours. In another, catastrophe. This summer has been a snapshot of that split-screen. The hottest day on record in parts of Europe, and a wave of water, mud and ice in Nepal that so far has claimed more than 750 lives. Thousands of people are still missing.
The difference is also one of resources. The climate crisis has an economic cost, but some places can absorb it better than others. Responses to this summer of wildfires in Europe included a rapid scrambling by the French government to provide everything from tax breaks for businesses affected by the fires to relocation costs and aid to rebuild homes. The UK government had deployed almost £100m before the summer to strengthen wildfire resilience.

Every summer, millions of people escape the heat and humidity of Tokyo by heading to the tranquil resort town of Karuizawa in Japan’s Nagano prefecture – just an hour by bullet train from the capital. Here, at the foot of Mount Asama, visitors stroll bamboo-lined pathways, cycle in verdant highlands, and practise the wellness ritual of shinrin-yoku, bathing among the cool hinoki forests. It would be the ideal nature retreat – if it wasn’t for the bears.
From June to August, bears often move close to Karuizawa, feeding on the mulberries, ants, leaves and cherry blossoms that grow near the town. Unlike nuts, these foods are low in calories, spurring the bears to seek out further sustenance. “They’re more likely to get close to residential spaces to see what they can find,” says Amelia Hiorns, a British zoologist who previously worked with Picchio Wildlife Research Centre in the town. “This combines with the busiest season for tourists.”

It is the earliest harvest Henry Astor can remember. But walking through the scorched wheatfields of his Cotswolds farm, signs of life are everywhere – swarms of insects, kaleidoscopic wildflower meadows, bushy hedgerows several metres wide. A yellowhammer perches on a nearby tree.
There are 18 other red-listed birds on the farm, says Astor, who this year ringed 23 barn owls, three kestrels, two little owls as well as goshawk chicks. “Last winter we had clouds of goldfinch, chaffinch and greenfinch,” he says. Britain has lost 73 million birds since 1970; but at Bruern Farms, a small but welcome reversal is taking shape.

When James Reed McGuire and Crystal Fritz first decided to replace their lawn with native plants, they did not really know what they were doing. As former city-dwellers who had moved from Chicago out to the suburb of Highland Park, Illinois, they had never done much gardening together beyond growing some planters of herbs and flowers on their balcony.
But for McGuire, an avid birder who did not want to live with a sea of turf that does “absolutely nothing for the environment”, figuring out an alternative to the suburban status quo was imperative.

The orphaned grizzly bear cubs were bulked up with a generous diet of roadkill, watermelon, dog food and snacks donated by the public. Their contact with carers was limited to two people. Then, after up to a year in rehabilitation, they returned home to the wilds of British Columbia.
“It’s a feelgood thing – people feel good when the cage opens,” says Dr Lana M Ciarniello, a bear specialist who tracked the Canadian yearlings in a recent study. There is a perception that bears will thrive in their natural habitat, she says. “The reality is they’re not followed up on.”

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.

In 2015, the whale researcher Valeria Vergara pitched a small tent at the icy water’s edge on Somerset Island in the remote Canadian high Arctic, shrouded in a freezing fog so thick she struggled to see her own hands. She trailed a cord out to the coast and plopped a hydrophone into the water to record the calls of belugas.
As many as 1,000 of the whales, accompanied by their newborn calves, frequented the surrounding bay. Belugas’ ceaseless chatter, made up of dozens of unique sounds, is crucial to keeping these creatures connected in the dim, turbid waters of the Arctic.

On a rocky beach in Cornwall, a group of wetsuit-clad freedivers and snorkellers are wading into the shallows. Below St Mawes Castle, built by Henry VIII to defend Falmouth harbour, they disappear in a swish of florescent pink and green fins.
They are volunteers, trained by the Cornwall Wildlife Trust to use underwater cameras and floating GPS devices to detect changes in marine habitats over time.

For many in the US region of New England, the lobster roll is synonymous with summertime. Loaded into a toasted bun, chunks of the sweet meat are served hot and soaked in butter, or chilled and slathered in mayonnaise with celery and herbs.
The only thing more debated than the recipe is the price: the once-humble roll now routinely fetches $30 (£22), or even $50, in a sign of the changing times – and seas.
