Frome, Somerset: Get tuned in to the river’s sounds and you’re treated to a symphony of noise, from susurrating hisses to great belches

After three decades living alongside mute waterways in East Anglia, with their soundless glide over clay, I am learning a liquid language here, and all its boulder dialects, as our winter‑filled local stream gushes down its limestone gorge.

My fellow country diarist and wild swimmer Amy-Jane Beer shares my passion for river music. She tells me of her compulsion to listen when fresh water is given a voice by coming to the surface.

Study links rapid growth of ocean macroalgae to global heating and nutrient pollution

Scientists have warned of a potential “regime shift” in the oceans, as the rapid growth of huge mats of seaweed appears to be driven by global heating and excessive enrichment of waters from farming runoff and other pollutants.

Over the past two decades, seaweed blooms have expanded by a staggering 13.4% a year in the tropical Atlantic and western Pacific, with the most dramatic increases occurring after 2008, according to researchers at the University of South Florida.

Everyone knew US electric car sales would be down in the 4th quarter. After the $7,500 US EV tax credit was killed, the only question was how far sales would drop. I like looking for surprises, though, and trying to find out what will happen or what happened that people ... [continued]

The good news about public EV chargers keeps coming. Just a bit after reporting about 88 new fast chargers planned for Brooklyn, NY, here’s another recent and relevant development. In nearby Queens and a little further out in Long Island, there will be a total of 80 public fast charging ... [continued]

A return to nuclear power is at the heart of Japan’s energy policy but, in the wake of the 2011 disaster, residents’ fears about tsunamis, earthquakes and evacuation plans remain

The activity around the Kashiwazaki-Kariwa nuclear power plant is reaching its peak: workers remove earth to expand the width of a main road, while lorries arrive at its heavily guarded entrance. A long perimeter fence is lined with countless coils of razor wire, and in a layby, a police patrol car monitors visitors to the beach – one of the few locations with a clear view of the reactors, framed by a snowy Mount Yoneyama.

When all seven of its reactors are working, Kashiwazaki-Kariwa generates 8.2 gigawatts of electricity, enough to power millions of households. Occupying 4.2 sq km of land in Niigata prefecture on the Japan Sea coast, it is the biggest nuclear power plant in the world.

Germany’s 400 km hydrogen backbone segment is now pressurized, full of fossil hydrogen, and waiting. There are no meaningful suppliers connected to it and no contracted offtakers drawing molecules out. That fact alone makes it worth slowing down and doing the accounting carefully, because large infrastructure decisions do not become ... [continued]

Some regions of the continent have enough ice to push up sea levels by 15 metres if they all melt, but researchers don’t yet fully understand the consequences

On one side of Dr Ben Galton-Fenzi’s view across the vast Totten ice shelf, the sun sat low on the Antarctic horizon. On the other, a full moon.

The ice shelf is “flat and white”, says Galton-Fenzi. “If there’s cloud around, you lose the horizon.”

Food produce and other waste has been littering Sussex coastline as capsized shipping containers wash ashore

Coral Evans was walking along the beach in Brighton on Tuesday evening when she came across an unfamiliar sight.

“Hundreds of dust masks had washed up, along with single-use plastic gloves and cans of dried milk,” she said. “It was odd to see in winter – because nothing surprises us in summertime with the amount of people on the beach.”

There are so many koalas in some places that food is the issue – while elsewhere populations are threatened by habitat loss. And there are no easy fixes

• Sign up for climate and environment editor Adam Morton’s free Clear Air newsletter here

On French Island in Victoria’s Western Port Bay, koalas are dropping from trees. Eucalypts have been eaten bare by the marsupials, with local reports of some found starving and dead. Multiple koalas – usually solitary animals – can often be seen on a single gum.

Koalas were first introduced to French Island from the mainland in the 1880s, a move that protected the species from extinction in the decades they were extensively hunted for their pelts. In the absence of predators and diseases such as chlamydia, the population thrived.

Pricing fertilizer emissions sounds like a recipe for more expensive food, but when the numbers are worked carefully, it turns out to be a policy that cuts emissions sharply while barely moving grocery prices. The reason is simple and counterintuitive. Fertilizer is a large share of farm costs and an ... [continued]

A new analysis by T&E shows that 25% of European aviation’s contrail-related global warming comes from night flights in autumn and winter, which make up just 10% of European air traffic. Contrail warming is highly seasonal and concentrated in time: in 2019, 75% of European contrail warming occurred between January to ... [continued]

Fears of storm surges and flooding, with landslides and volcanic mudflows possible on Luzon

The Philippines is experiencing its first tropical storm of the year. Ada, also known as Nokaen, slowly developed into a tropical storm on Friday, travelling northwards along the east coast over the weekend and bringing torrential rain of up to 200mm a day and maximum wind gusts of up to 65mph near the storm’s centre.

The system is expected to remain a tropical storm until Tuesday as it tracks north-west, though weakening as a result of the incoming north-east monsoon, transitioning back to a tropical depression, which could bring further rain and strong winds enhanced by the monsoon later in the week.

Electricity generation by the U.S. electric power sector totaled about 4,260 billion kilowatthours (BkWh) in 2025. In our latest Short-Term Energy Outlook (STEO), we expect U.S. electricity generation will grow by 1.1% in 2026 and by 2.6% in 2027, when it reaches an annual total of 4,423 BkWh. The three main dispatchable ... [continued]

Pioneering scheme hopes species that thrived for thousands of years in Irish waters can do so again

The dinghy slowed to a stop at a long line of black bobbing baskets and David Lawlor reached out to inspect the first one.

Inside lay 60 oysters, all with their shells closed, shielding the life within. “They look great,” beamed Lawlor. So did their neighbours in the next basket and the ones after that, all down the line of 300 baskets, totalling 18,000 oysters.

Experts call for tighter regulation as GPS tracking reveals how people’s behaviour affects the lives of some of the world’s largest birds

Many people look up to admire the silhouette of raptors, some of the planet’s largest birds, soaring through seemingly empty skies. But increasingly, research shows us that this fascination runs both ways. From high above, these birds are watching us too.

Thanks to the development of tiny GPS tracking devices attached to their bodies, researchers are getting millions of data points on the day-to-day lives of these apex predators of the skies, giving us greater insight into where they hunt and rest, and how they die.

Trust had $254m invested in companies such as Chevron, BP and Shell in 2024, a nine-year record, analysis shows

The Gates Foundation Trust holds hundreds of millions of dollars in fossil fuel extractors despite Bill Gates’ claims of divestment made in 2019.

End-of-year filings reveal that in 2024 the trust invested $254m in companies that extract fossil fuels such as Chevron, BP and Shell. This was a nine-year record and up 21% from 2016, Guardian analysis found. Adjusting for inflation, it was the highest amount since 2019.
