A ‘wetter farming’ project explores rehydrating peatland to help grow crops in boggier conditions while cutting CO2 emissions
“I really don’t like the word ‘paludiculture’ – most people have no idea what it means,” Sarah Johnson says. “I prefer the term ‘wetter farming’.”
The word might be baffling, but the concept is simple: paludiculture is the use of wet peatlands for agriculture, a practice that goes back centuries in the UK, including growing reeds for thatching roofs.

Greatest growth in rural areas as increase in homes with wood-burning stoves contributes to new air pollution hotspots
Growing numbers of UK homes with wood-burning stoves are leading to new air pollution hotspots.
Analysis by led by University College London (UCL) found that the spatial density of burners is related to the amount of air pollution that builds up in neighbourhoods on winter evenings. The greatest density of wood burners was found in urban areas outside major cities. The list was topped by Worthing, Norwich, Reading, Cambridge and Hastings councils, which all had more than 100 wood burners per square kilometre.

From the turtle-nesting beaches of Italy to Greek island bird havens, across the Mediterranean campaigners are fighting to protect habitats from tourists seeking a picture-perfect holiday
In the summer months in Puglia, southern Italy, the battle for the beaches begins before dawn. Armed with tractors, beach owners flatten every imperfection from the sand, dragging it to sift out anything large enough to be considered waste. As the sun rises, tourists flood the coastline, often unaware of what lies hidden beneath their feet.
Two feet below the surface, delicate eggs laid by loggerhead sea turtles (Caretta caretta) are waiting to hatch. For the turtles, the beach is not a beauty spot but a habitat.

Cairngorms national park: They’re in there somewhere, performing their morning breeding displays this time of year. But some things are better left unseen
There’s an inexorable pull into the pinewoods in these spring early mornings. On the loch, the sun-kissed mist is lifting and a male goldeneye displays, tipping its head back as it ripples across the water. Skeins of overwintering geese are still leaving for their breeding grounds farther north, and yet the summer’s chiffchaffs are also calling; I hear the first willow warblers too. Bright green clover-like leaves foretell the sprinklings of wood sorrel soon to come, and a flock of yellow-green and black streaked siskins flash in the sunlight – but I resist the temptation to follow them into the heart of the woods, for other spring rituals are taking place there.
It’s the time of year for early morning capercaillie leks, where the males congregate in hidden clearings in the middle of the woodsto display and attract a mate. Capercaillies are huge members of the grouse family, thought to have inhabited old-growth pinewoods like these since the last ice age. In the UK, they’re only found in the pinewoods of Scotland, with the Cairngorms their stronghold. They’re incredible birds. The females are a cryptic brown, the males even bigger, with a red-rimmed eye, black and white with a fan-like tail that they spread during display. Their decline in Scotland has been precipitous, from more than 20,000 in the 1970s to just over 500 now.

Exclusive: Britain is key financial hub for destructive fossil fuel mega-projects, according to research
Banks in the City of London have poured more than $100bn (£75bn) into companies developing “carbon bombs” – huge oil, gas and coal projects that would drive the climate past internationally agreed temperature limits with catastrophic global consequences – according to a study.
Nine London-based banks, including HSBC, NatWest, Barclays and Lloyds are involved in financing companies responsible for at least 117 carbon bomb projects in 28 countries between 2016 – the year after the landmark Paris agreement was signed – and 2023, according to the study.

Labour politicians warn former PM had boosted Tory and Reform climate sceptics on the eve of local elections
Tony Blair has been forced by Downing Street to row back from his criticism of the government’s net zero strategy after furious Labour politicians warned he had given a boost to Tory and Reform sceptics on the eve of the local elections.
Climate experts also accused the former prime minister of granting political cover to fossil fuel interests and weakening momentum behind the UK’s legally binding target to reach net zero emissions by 2050.

As big companies and informal miners blame each other for the damage to rivers and forests, mining risks long-term harm to those living nearby
The small town of Muzo, nestled deep in Colombia’s emerald-rich valleys of Boyacá province, is a place where the soil holds great wealth. Brick-red homes and tin-roof shacks cling to the mountainside, their bases resting on black sand and dark mud. Below, the Río Minero weaves through the valley, its waters tainted by the silt and debris of continuous excavation.
The region’s natural beauty is marred by scattered waste and discarded mining materials, evidence of an industry that supports the town’s economy – but also harms its environment.

Most countries have no fossil fuel reserves, but no country in the world is without renewable energy resources. For a country such as Iceland, the world leader in renewables, this statement is clear to see. The island nation has made good use of its volcanoes and glaciers, which help provide 100% of its electricity and almost all its heat energy. But what about other countries that don't have Iceland's unique geology to rely on. Josh Toussaint-Strauss finds out how the world has managed to reach the impressive milestone of more than 40% of global electricity demand coming from clean power sources, and how other countries such as the UK are making this energy transition happen, despite a distinct lack of volcanoes

Guardian reporters map out how Trump is eviscerating efforts to protect the natural world – from ‘drill, baby, drill’ to mass firings
Donald Trump has never been mistaken for an environmentalist, having long called the climate crisis a “giant hoax” and repeatedly lauding the supposed virtues of fossil fuels.
But the US president’s onslaught upon the natural world in this administration’s first 100 days has surprised even those who closely charted his first term, in which he rolled back environmental rules and tore the US from the Paris climate agreement.
Taken more than 140 actions to roll back environmental rules and push for greater use of fossil fuels.
Set about rewriting regulations that limit pollution from cars, trucks and power plants.
Officially reconsidering whether greenhouse gases actually cause harm to public health.
Legally targeted states that have their own laws on tackling the climate crisis.
Speeded up environmental reviews of drilling projects, from years to just a few weeks.
Winding back water efficiency standards for showers and toilets and halting a phase-out of plastic straws

Aluminium emissions from satellites as they fall to Earth and burn up is becoming more significant as their numbers soar
Right now there are more than 9,000 satellites circumnavigating overhead, keeping track of weather, facilitating communications, aiding navigation and monitoring the Earth. By 2040, there could be more than 60,000. A new study shows that the emissions from expired satellites, as they fall to Earth and burn up, will be significant in future years, with implications for ozone hole recovery and climate.
Satellites need to be replaced after about five years. Most old satellites are disposed of by reducing their altitude and letting them burn up as they fall, releasing pollution into Earth’s atmosphere such as aerosolised aluminium. To understand the impact of these growing emissions from expired satellites, researchers simulated the effects associated with an annual release of 10,000 tonnes of aluminium oxide by 2040 (the amount estimated to be released from disposal of 3,000 satellites a year, assuming a fleet of 60,000 satellites).
