Exclusive: Getting rid of premium seats, ensuring flights are near full and using efficient aircraft could slash CO2, analysis suggests
Climate-heating emissions from aviation could be slashed in half – without reducing passenger journeys – by getting rid of premium seats, ensuring flights are near full and using the most efficient aircraft, according to analysis.
These efficiency measures could be far more effective in tackling the fast-growing carbon footprint of flying than pledges to use “sustainable” fuels or controversial carbon offsets, the researchers said. They believe their study, which analysed more than 27m commercial flights out of approximately 35m in 2023, is the first to assess the variation in operational efficiency of flights across the globe.

‘Everybody loses’ if production supercharged in country with largest known oil reserves, critics say
Donald Trump, by dramatically seizing Nicolás Maduro and claiming dominion over Venezuela’s vast oil reserves, has taken his “drill, baby, drill” mantra global. Achieving the president’s dream of supercharging the country’s oil production would be financially challenging – and if fulfilled, would be “terrible for the climate”, experts say.
Trump has aggressively sought to boost oil and gas production within the US. Now, after the capture and arrest of Maduro and his wife, Cilia Flores, he is seeking to orchestrate a ramp-up of drilling in Venezuela, which has the largest known reserves of oil in the world – equivalent to about 300bn barrels, according to research firm the Energy Institute.

Inishowen, County Donegal, Ireland: There’s not much light to play with today, deep in midwinter, but this once-coveted fort still puts on a show
Maybe it’s the invitation of the slowly lengthening days, but at this time of year I crave a long view. And here, on the approach to the ringfort of Grianán of Aileach, I have it. As the late afternoon sun squints over the fort’s high walls, it’s easy to understand why early medieval monarchs cherished this summit.
I watch my shadow loping across the heath before my gaze plunges to the Inch Levels reserve, where flocks of wintering whooper swans and greylag geese speckle the flooded fields. I stop for a moment, lingering over the sky’s perfect reflection in the reserve’s brackish lagoon, with Lough Swilly beyond. Not far from here to Ireland’s northernmost edge and the Atlantic Ocean.

When rain falls on snow it creates a layer of ice that impedes feeding, which in turn has reduced herds’ birthrates
Reindeer survive typically harsh Arctic winters by using their specially adapted hooves to scrape through the snow to nibble on the lichen and moss below. But paradoxically a warming climate is making it harder for them to reach this food, and research shows it has led to a drop in reindeer birthrates.
When rain falls on snow, the snow melts and refreezes, creating layers of ice that make it more difficult for reindeer to scrape through to the fodder below. Climate records going back to 1960 show that warmer winters have resulted in more rain-on-snow events in Arctic regions. By comparing the weather data with reindeer herd birth statistics from Norway and Finland, researchers have shown that birth rates tend to drop in summers that follow winters with lots of rain-on-snow events.

Every year a Chinese-dominated flotilla big enough to be seen from space pillages the rich marine life on Mile 201, a largely ungoverned part of the South Atlantic off Argentina
In a monitoring room in Buenos Aires, a dozen members of the Argentinian coast guard watch giant industrial-fishing ships moving in real time across a set of screens. “Every year, for five or six months, the foreign fleet comes from across the Indian Ocean, from Asian countries, and from the North Atlantic,” says Cdr Mauricio López, of the monitoring department. “It’s creating a serious environmental problem.”
Just beyond Argentina’s maritime frontier, hundreds of foreign vessels – known as the distant-water fishing fleet – are descending on Mile 201, a largely ungoverned strip of the high seas in the South Atlantic, to plunder its rich marine life. The fleet regularly becomes so big it can be seen from space, looking like a city floating on the sea.

Problem at water treatment centre left 24,000 Tunbridge Wells homes without drinking water for two weeks
A failure at a water treatment centre that left tens of thousands of Kent households without water was foreseen weeks before it happened and could have been stopped, the regulator has said.
Twenty-four thousand homes in the Tunbridge Wells area were without drinking water for two weeks from 30 November last year due to a failure at the Pembury water treatment centre.

Behind the west’s huge appetite for the fruit lies the dark reality of environmental destruction and Indigenous exploitation in Mexico
I grew up in San Andrés Tziróndaro, a Purépecha community on the shores of Lake Pátzcuaro in the Mexican state of Michoacán. My childhood was shaped by water, forests and music. The lake fed us. The forest protected us. In the afternoons, people gathered in the local square while bands passed through playing pirekua, our traditional music.
That way of life is now under threat as our land is extracted for profit.

A year after the Eaton fire, residents returning to Altadena confront lingering contamination and little official clarity
One year on from the Eaton fire, long after the vicious winds that sent embers cascading from the San Gabriel mountains and the flames that swallowed entire streets, a shadow still hangs over Altadena.
Construction on new properties is under way, and families whose homes survived the fire have begun to return. But many are grappling with an urgent question: is it safe to be here?

Across Africa, baobabs have rich symbolic meaning, but the breakneck expansion of the DRC’s capital has reduced their number in the city centre to one
The older inhabitants of Kinshasa can remember when trees shaded its main avenues and thick-trunked baobabs stood in front of government offices.
Jean Mangalibi, 60, from his plant nursery tucked among grey tower blocks, says the capital of the Democratic Republic of the Congo’s frenzied expansion has all but erased its greenery. “We’re destroying the city,” he says, over the sound of drilling from a nearby building site.

Twenty-five years after I revealed the practices of the industrial food giants, the profits – and dangers – of mass producing meat and milk have only grown
Cats have long been kept at American dairy farms to kill rats, mice and other rodents. In March 2024, a number of barn cats at dairies in the Texas panhandle started to behave strangely. It was like the opening scene of a horror movie. The cats began to walk in circles obsessively. They became listless and depressed, lost their balance, staggered, had seizures, suffered paralysis and died within a few days of becoming ill. At one dairy in north Texas, two dozen cats developed these odd symptoms; more than half were soon dead. Their bodies showed no unusual signs of injury or disease.
Dr Barb Petersen, a veterinarian in Amarillo, heard stories about the sick cats. “I went to one of my dairies last week, and all their cats were missing,” a colleague told her. “I couldn’t figure it out – the cats usually come to my vet truck.” For about a month, Petersen had been investigating a mysterious illness among dairy cattle in Texas. Cows were developing a fever, producing less milk, losing weight. The milk they did produce was thick and yellow. The illness was rarely fatal but could last for weeks, and the decline in milk production was hurting local dairy farmers. Petersen sent fluid samples from sick cows to a diagnostic lab at Iowa State University, yet all the tests came back negative for diseases known to infect cattle. She wondered if there might be a connection between the unexplained illnesses of the cats and the cows. She sent the bodies of two dead barn cats to the lab at Iowa State, where their brains were dissected.
