As the rising number of vessels in the icy waters increases the risk of environmental disaster, scientists are scrambling to find potential solutions

Last winter, inside the subarctic Churchill Marine Observatory in Canada, scientists embarked on an experiment they hoped would result in a gamechanging remedy for polluted Arctic waters. They released130 litres of diesel into an ice-covered pool filled with raw seawater pumped in from Hudson Bayand naturally occurring oil-eating microbes. The technique had been used successfully during the Deepwater Horizon oil spill in the Gulf of Mexico, and the scientists wanted to see if they could break down oil in colder waters.

The microbes were sluggish in response and the population showed little change after the first three weeks, says Eric Collins, a microbiologist at the University of Manitoba in Winnipeg, who led the project. But that did not last. “When we went back eight weeks later, we saw that there was a big change,” Collins says. “One particular bacterium grew to a very high abundance in the tanks and it was clear that it was feeding on the oil.” But two months is too long to wait should an oil spill occur. Time is of the essence.

All this year we’re exploring why we love heat pump water heaters. On Valentine’s Day, we talked about how HPWHs are so lovable because they save so much money on utility bills. For Earth Day, we want to talk about how much we love HPWHs for cleaning our air. Yes, ... [continued]

The United Kingdom has far more public EV charger points than gas (petrol) pump nozzles, and yet many residents may not fully understand this fact.

While wildlife populations crash globally, research finds designated areas enable recovery of threatened species

Wildlife and humans are thriving within sites recognised by Unesco, research has found, allowing for the recovery of threatened species and habitats around the world.

While wildlife populations have crashed globally by nearly three-quarters since 1970, those within Unesco-protected areas have remained largely stable.

One way to pay for wildlife conservation is to allow the rich to bag a few animals for high prices. But critics see this approach as an exercise in neocolonialism

You can kill almost anything if you’re willing to pay. Big or small. Land, water or air. Ten a penny or one of the last of its kind. There’s nearly always a way, though it might not make you popular. The Niassa special reserve, a vast reservation larger than Switzerland, stretches for 190 miles along the northern rim of Mozambique, taking in 4.2m hectares of woodland and rivers. The reserve, one of the world’s largest protected areas, is home to elephants, leopards, hyenas, zebras and about 1,000 wild lions.

That word, however: protected. It applies to some, but not all, of its animal inhabitants. Each year, a specific number are set aside for sacrifice, for the greater good. Not long ago,I joined an expedition in Niassa, with one of Africa’s top game-hunting companies.

‘Stone age’ system of booking cross-border rail tickets holding back climate action by consumers, says thinktank

Europe’s “stone age” system of booking train tickets makes it needlessly difficult for travellers to avoid polluting flights, a report has found.

Booking equivalent train tickets is “difficult or impossible” on almost half of the EU’s busiest international air routes, analysis from the Transport & Environment (T&E) thinktank shows.

Sarah Finch’s fight against drilling led to a landmark ruling on fossil fuel emissions – and a leading environmental prize

It started with a notice in the local newspaper and ended with winning one of the world’s most prestigious environmental prizes. In 2010, Sarah Finch was flicking through the local planning notices when one caught her eye: a proposal to drill for oil at Horse Hill in Surrey, just outside Crawley, over the border in West Sussex, 6 miles (10km) from her home.

Surrey is not the kind of place one expects to find the oil industry. It’s a county of little villages, farms, woods and commuter railway stations. Its semi-rural landscape stretches off towards the horizon in a typically English green patchwork. It is difficult to envision it littered with nodding donkey pumpjacks and gas flares.

UK’s Rare Breeds Survival Trust says calf numbers of white park cattle last year were less than two-thirds of 2022 level

An ancient breed of cattle whose ancestors are thought to have accompanied the Celts as they were pushed to Britain’s fringes by the Romans has been designated as urgently at risk by a UK conservation charity.

Publishing its 2026 watchlist on Tuesday, the Rare Breeds Survival Trust moved white park cattle to its “priority” category as new calf numbers sank last year to less than two-thirds of their 2022 level.

About 500 farmers challenge Green Gen Cymru in high court over alleged disregard for landowners and biosecurity

A group of 500 Welsh farmers have brought a landmark legal claim to the high court over the alleged conduct of a green energy developer planning to build electricity pylon routes across their land.

The court will hear allegations that Green Gen Cymru “unlawfully sought entry to private land, intimidated landowners, and showed disregard for biosecurity and basic rights”, as well as examine laws that force landowners to sell property to utility companies, in a hearing on Tuesday and Wednesday.

The country is seeing an increase in human-wildlife conflict as the number of megafauna, including rhinos and tigers, grows. But there are efforts to tackle the problem around Chitwan national park through education and training

The tourists lining the steep embankment buzzed with excitement, phones out, snapping away in the twilight as a wild Indian rhinoceros grazed below the Nepali village of Sauraha. Climbing to the main street, the rhino ambled down the middle of the road.

Local people warned tourists to give it plenty of space. All manner of wheeled vehicles slowed, then passed. The rhino turned its horn at a cyclist passing too close, triggering gasps from the assembled crowd.

Exclusive: Report finds Natural England has created no new SSSIs, which protect areas from development, since 2023

The government’s wildlife watchdog for England is failing to save nature because it has stopped giving protection to rare wildlife and habitats, according to a new report.

No new sites of special scientific interest (SSSIs) have been designated by Natural England since 2023. SSSIs are nationally or internationally important places for rare wildlife and habitats. Without the designation, endangered species can be at risk of being lost to development.
