Levels of deadly pollutants have dropped, with significant improvements in capital’s most deprived areas

People in London have been breathing significantly cleaner air since the expansion of the ultra low emission zone (Ulez), a study has found.

Levels of deadly pollutants that are linked to a wide range of health problems – from cancer to impaired lung development, heart attacks to premature births – have dropped, with some of the biggest improvements coming in the capital’s most deprived areas.

More than 3,000 critically endangered Baw Baw frogs have been released in Victoria’s east as part of a record-breaking conservation breeding program.

Zoos Victoria’s reintroduction of 3,000 tiny froglets and 40 adult frogs into the high-altitude forests of the Baw Baw plateau, about 120km east of Melbourne, was the largest in its breeding program for the species.

Blue Marine Foundation charity asks high court to declare quota decision unlawful amid concern over sustainability of fish stocks

At the start of 2024, Jerry Percy, who led the New Under Ten Fishermen’s Association, dedicated to small boats, said he started to receive lots of calls from members. “They were calling my office to report that a lack of fish in the inshore grounds were putting their livelihoods in peril,” he said.

The fishers said they had noticed a depletion of species such as pollack, typically caught off Britain’s coasts.

Vow in 2020 aimed to keep shot out of human food chain but study finds most game carcasses still contain lead

A voluntary promise to phase out toxic lead shot in the UK has failed, meaning wildlife and human health are being put at risk, a study has found.

The vow, made in February 2020 by the UK’s nine leading game shooting and rural organisations, aimed to benefit wildlife and the environment and keep toxic lead out of the human food chain. They aimed to phase lead shot out by 2025, and hoped to avoid a full government ban. It is recommended birds are shot with non-toxic cartridges made of metals such as steel instead.

Scientists called the news ‘particularly worrying’ because ice reflects sunlight and cools the planet

Global sea ice fell to a record low in February, scientists have said, a symptom of an atmosphere fouled by planet-heating pollutants.

The combined area of ice around the north and south poles hit a new daily minimum in early February and stayed below the previous record for the rest of the month, the EU’s Copernicus Climate Change Service (C3S) said on Thursday.

Group claims regulator signed off on ‘broken system’ making customers pay for industry’s neglect

An environmental group is to take legal action against Ofwat, the water regulator, accusing it of unlawfully making customers pay for decades of neglect by the water industry.

River Action will file the legal claim this month, arguing that bill rises for customers that have been approved by the regulator could be used to fix infrastructure failures that should have been addressed years ago.

He is surrounded by people who have grandiose plans and dreams beyond our planet. Vengeful nihilism is a big part of the Maga project

In thinking about the war being waged against life on Earth by Donald Trump, Elon Musk and their minions, I keep bumping into a horrible suspicion. Could it be that this is not just about delivering the world to oligarchs and corporations – not just about wringing as much profit from living systems as they can? Could it be that they want to see the destruction of the habitable planet?

We know that Trump’s overriding purpose is power. We have seen that no amount of power appears to satisfy his craving. So let’s consider power’s ultimate destination. It is to become not only an emperor, but the last of the emperors: to close the chapter on civilisation. It is to scratch your name indelibly upon a geological epoch. Look on my works, ye vermin, and despair.

Study on cancer data in US agricultural heartland finds children more at risk than if exposed to just one pesticide

Exposure to multiple pesticides significantly increases the risk of childhood cancers compared with exposures to just one pesticide, first-of-its-kind research finds, raising new fears that children are more at risk to the substances’ harmful effects than previously thought.

The study’s authors say they are the first to look at the link between exposures to multiple widely used pesticides and the most common childhood cancers. Most research considers pesticides’ toxicity on an individual basis, and the substances are regulated as if exposures occur in isolation from one another.

Another day, another health scare. I’m struggling to know which dangers I should take seriously

If you want to stir up online controversy, wooden spoons are the perfect tool with which to do so. Every few years, influencers go viral with warnings about how the wooden spoons in your kitchen are covered in disgusting gunk and if you don’t boil them immediately you will poison yourself and everyone you love.

In 2023, for example, a woman called Lulaboo Jenkins posted a TikTok video of her boiling spoons. Millions of people watched the water turn brown and it triggered a deep-cleaning craze. The Guardian’s Tim Dowling had a go, detailing the results in an article that prompted more than 1,000 comments. Who knew spoons could inspire such a feverish response? (Well, Jenkins, I suppose.)

Guardian analysis finds fossil-fuel and mining firms have won $92bn of public money from states, with a growing number of cases backed by financial speculators

Financial speculators are investing in a growing number of lawsuits against governments over environmental laws and other regulations that affect profits, often generating lucrative awards, the Guardian has found.

For a long time, litigation finance thrived primarily in the realm of car crashes and employment claims. “Had an accident that wasn’t your fault?” was the industry’s billboard catchphrase, offering to finance lawsuits in exchange for a cut of any payout.

The plant multiplies quickly, is rich in vitamins, and eaten across Asia. Why isn’t it on supermarket shelves?

In the summer sun, duckweed (Wolffia globosa) can be a menace. It grows so fast it covers a pond in a few days, blocking out the light for the life below. But it is this ability to multiply and its high nutritional value that has made it a potentially valuable food.

Although commonly eaten in Asia, where varieties of duckweed are also known as water lentils or watermeal, it has taken nearly 10 years for scientists to convince the European Food Safety Authority that it is a vegetable that is safe to eat.

Researchers say data strengthens case for holding firms to account for their contribution to climate crisis

Half of the world’s climate-heating carbon emissions come from the fossil fuels produced by just 36 companies, analysis has revealed.

The researchers said the 2023 data strengthened the case for holding fossil fuel companies to account for their contribution to global heating. Previous versions of the annual report have been used in legal cases against companies and investors.

Scientists are studying whether the grounded A23a iceberg might help stir nutrients and make food more available for penguins and seals

The world’s biggest iceberg appears to have run aground roughly 70km (43 miles) from a remote Antarctic island, potentially sparing the crucial wildlife haven from being hit, a research organisation said Tuesday.

The colossal iceberg A23a – which measures roughly 3,300 sq km and weighs nearly 1tn tonnes – has been drifting north from Antarctica towards South Georgia island since 2020.

How do you stop people worrying about the climate emergency? By sacking anyone whose job it is to keep an eye on it. Chalk up another win for Project 2025

Some politicians go whichever way the wind blows. Not, however, the US’s esteemed leader, Donald Trump. He is such a force of nature that he can dictate the direction of the wind. During his first term, he suggested “nuking hurricanes” to stop them from hitting the country. A few weeks after that, Trump seemed to think he could alter the course of Hurricane Dorian with a black marker, scribbling over an official map to change its anticipated trajectory in an incident now known as Sharpiegate. Weirdly, Dorian did not end up following Trump’s orders. Hurricanes can be uncooperative like that.

Six weeks into Trump’s second term, the president hasn’t bombed any hurricanes, but he has nuked the US’s weather-forecasting capabilities. Last week, hundreds of workers at the National Oceanic and Atmospheric Administration (Noaa), the US’s pre-eminent climate research agency, were abruptly fired.

Researchers at University of Exeter warn many of the hunted species are important crop pollinators

Invasive Asian hornets are eating hundreds of different species of insects in Europe, including many which are important pollinators, researchers have warned.

The findings, from tests of the guts of more than 1,500 larvae, raise new concerns over the “extra threat” the hornet poses to native insects already under pressure from farming, changes in land use and chemical pollution.

The highly concentrated egg market may be contributing to soaring consumer prices – and the spread of the virus, data shared exclusively with the Guardian shows

Major egg corporations may be using avian flu as a ruse to hike up prices, generating record profits while hurting American consumers, new research suggests.

The cost of a dozen large eggs hit almost $5 in January – a record high in the US and more than two and a half times the average price three years ago before the avian flu outbreak. This signifies a 157% inflation rate for eggs – a previously go-to affordable protein source for many American families.

Gasps from dockside crowd watching Bigg’s orca pod in event described as ‘once-in-a-lifetime experience’

A pod of orcas swam close to shore and amazed onlookers in Seattle by treating the whale watchers to the rare sight of the apex predators hunting a bird.

The pod of Bigg’s killer whales visited Elliott Bay and were seemingly on a hunt underwater just off Seattle’s maritime industrial docks. The pod exited the bay close to the West Seattle neighborhood across from downtown, where people were waiting to catch sight of them.

Uncertainty over climate and economy means ‘investment portfolio’ approach needed, researchers say

An “investment portfolio approach” needs to be applied to large-scale tree planting across the world to reduce the risks of the wrong species being planted in the wrong place, economists have said.

Countries have made ambitious pledges to plant billions of trees to remove greenhouse gases and tackle global heating. The UK has committed to plant 30,000 hectares (74,000 acres) of trees each year by 2025 and maintain the rate until 2050, the European Commission has pledged to plant 3bn trees across member states by 2030, and the US under the previous administration committed to planting 1bn trees by the same date.

Environmental groups say two-year grace period allowed by Ursula von der Leyen ‘rewards laggard’ manufacturers

European carmakers are to be given two extra years to meet this year’s pollution target, the European Commission president, Ursula von der Leyen, has said, in a further rollback of her green deal climate policies.

Companies who sell too many dirty vehicles this year will be allowed to compensate by selling more clean vehicles in the two years that follow, under a proposal that would stretch the window of compliance for the 2025 fleet emissions target to 2027.

Every year, volunteers brave the icy Tuel Lane lock in West Yorkshire to clear leaves, litter – and pickled onions

It is said that an imitation Rolex watch was once found during the spring clean of the UK’s deepest canal lock. Today the most glamorous discoveries are a Tesco shopping trolley and an empty can of Sprite – but spirits are still high.

“I did once come across a full jar of pickled onions,” said Maureen Readle, a volunteer. “But that was a bit further up. Here it is mostly leaves.”
