Study also says Balkan levels are often higher than in Beijing – and sometimes among the highest in the world

When we think of the world’s most polluted cities, images of Delhi or Beijing come to mind, but new data has revealed acute pollution problems close to the heart of Europe.

Prof Andre Prevot, of the Paul Scherrer Institute (PSI) in Switzerland, explained: “In winter, the particle pollution in the Balkans is the highest in Europe. Particle pollution levels are often higher than in Beijing and on some days they are among the highest in the world. Sulphur dioxide in winter can be over 30 times greater than what we normally see in western Europe.”

I have a Tesla Model 3 that is more than 6 years old, so I will discuss what upgrades to a new Tesla could do for me. However, note that you could now trade a used Tesla in for over 75 different EV models from Rivian, Ford, Chevrolet, Hummer, Cadillac, ... [continued]

Wolves killed more than 2,100 reindeer in Finland last year, and herders are blaming the Ukraine war

Juha Kujala no longer knows how many reindeer will return to his farm from the forest each December. The 54-year-old herder releases his animals into the wilderness on the 830-mile Finnish-Russian border each spring to grow fat on lichens, grass and mushrooms, just as his ancestors have done for generations.

But since 2022, grisly discoveries of reindeer skeletons on the forest floor have disrupted this ancient way of life. The culprits, according to Kujala: wolves from Russia.

An extraordinary mosaic of wildlife has made Britain’s urban jungle its home

London is the only place in the UK where you can find scorpions, snakes, turtles, seals, peacocks, falcons all in one city – and not London zoo. Step outside and you will encounter a patchwork of writhing, buzzing, bubbling urban microclimates.

Sam Davenport, the director of nature recovery at the London Wildlife Trust, emphasises the sheer variation in habitats that you find in UK cities, which creates an amazing “mosaic” of wildlife.

Pollution from wood burners kills thousands but proposed emissions limit would cut toxic particles by 10%

New wood-burning stoves will carry a health warning highlighting the impact of the air pollution they produce, under UK government plans.

Ministers have also proposed cutting the limit on the smoke emitted from wood burners by 80%. However, the measure would only apply to new stoves, most of which already meet the stricter limit. The new limit would cut the annual toxic emissions from wood burning in the UK by only 10% over the next decade, according to the consultation.

This year’s RSPB Big Garden Birdwatch, which begins on Friday, could reveal ‘some surprise migratory visitors’

The chances of spotting a fieldfare or redwing in 2026 have risen, thanks to cold and unsettled weather in Europe, prompting a bumper year in birds migrating to the UK.

The RSPB highlighted the trend on the eve of the Big Garden Birdwatch, an annual event that constitutes the world’s largest garden wildlife survey, which will take place between 23 and 25 January.

Coroner is yet to determine the cause of death of Piper James, a 19-year-old Canadian woman found surrounded by dingoes on Monday

In the early hours of Monday morning, a young woman’s body was found being mauled by a pack of dingoes near a shipwreck on a windswept stretch of white sand beach on an island off the east coast of Australia.

The island was K’gari, formerly known as Fraser Island, in southern Queensland, home to about 150 human inhabitants and a population of dingoes genetically distinct from those on the mainland. Called wongari in the language of its Butchulla traditional owners, the lean yellow and white canids are sacred to the First People and indelibly entwined in the cultural fabric of this world-heritage listed sand island.

Oil, out-of-date milk and even roast dinner residues contribute to the growth of fatbergs, a sticky problem for sewerage systems

• Change by degrees offers life hacks and sustainable living tips each Saturday to help reduce your household’s carbon footprint

Fatbergs are a sticky problem for sewerage systems – blocking pipes, spawning poo balls, and even forcing the cancellation of a Bryan Adams concert.

When households pour cooking oils, out-of-date milk or the residues of a roast dinner down the sink, it contributes to the buildup of fats, oils and grease – known as FOG – in the wastewater system, and the growth of fatbergs.

Experts say climate crisis, corruption and lack or misuse of infrastructure among factors driving water conflicts

Water-related violence has almost doubled since 2022 and little is being done to understand and address the trend and prevent new and escalating risks, experts have said.

There were 419 incidents of water-related violence recorded in 2024, up from 235 in 2022, according to the Pacific Institute, a US-based thinktank.

Researchers found a new way to filter and destroy Pfas chemicals at 100 times the rate of current systems

New filtration technology developed by Rice University may absorb some Pfas “forever chemicals” at 100 times the rate previously possible, which could dramatically improve pollution control and speed remediations.

Researchers also say they have also found a way to destroy Pfas, though both technologies face a steep challenge in being deployed on an industrial scale.
