Trump’s rollback of toxic gas rules limits EPA’s authority to protect public health, analysis says

Ethylene oxide (EtO) is about 60 times more carcinogenic than believed in 2006, research finds

A new Trump administration plan to rescind 2024 regulations for toxic ethylene oxide (EtO) pollution more broadly aims to limit the Environmental Protection Agency’s authority to strengthen public health protections around hazardous emissions and could result in more of the toxin being released into the air.

Recent research has found EtO is about 60 times more carcinogenic than thought when the last regulations were developed in 2006. In 2024, the Biden EPA passed a rule that strengthened the regulations to reflect the updated science, and required the nation’s EtO emitters to collectively cut their emissions by about 90%.

Labour must fulfil promise to introduce clean air act, charities urge

Party held out prospect of act while in opposition but plan did not make it into election manifesto

Ministers should bring forward a new clean air act that would ban wood burning, clear diesel vehicles from the roads and force councils to cut pollution, a group of more than 60 charities have urged before the king’s speech on Wednesday.

Labour held out the prospect of a clean air act while in opposition in 2023, but this was dropped from the final election manifesto, and the government has made no move to reinstate it.

Supermarket foods claiming to be ‘natural’ or ‘sustainable’ mostly just using marketing terms, researchers find

Survey of 27,000 Australian supermarket items found some products boasting environmental benefits had significantly higher emissions than unlabelled counterparts

Foods in supermarkets boasting environmental terms such as “natural” or “sustainable” are mostly just using marketing speak, rather than verified claims, Australian researchers have found.

More than 27,000 packaged foods sold at Coles, Woolworths, Aldi, IGA and Harris Farm supermarkets in Sydney were assessed by researchers from the George Institute for Global Health.

Sharp drop in ‘forever chemicals’ in seabird eggs hailed as win for regulation

Levels of Pfas in northern gannet eggs in Canada fell up to 74% over 55-year period of study

Levels of some of the most dangerous Pfas compounds have dramatically fallen in Canadian seabird eggs, which the authors of a new peer-reviewed study say illustrates how regulations are effective.

Researchers looked at Pfas levels in the eggs of northern gannets in the St Lawrence Seaway basin over a 55-year period. Pfas levels shot up from the 1960s through the peak of the chemicals’ use in the late 1990s and early aughts, then fell.

‘Amazon of America’: film paints vision of a post-coup Brazil giving up rainforest

Vitória Régia imagines rightwing Bolsonaro plot succeeded with US help – and highlights threats facing Indigenous peoples

The year is 2025 and far-right coup plotters have annihilated Brazil’s democracy, assassinating the president, closing the national congress and surrendering the Amazon rainforest and its untold riches to the United States.

“Ladies and gentlemen, welcome to the Amazon of America,” a thick-accented North American soldier tells a group of journalists being taken on a propaganda tour of an oil refinery in the newly annexed jungle realm. Nearby, a replica of the Statue of Liberty has been carved out of the wilderness to celebrate Washington’s tutelage over more than half of Brazil.

Trump administration relaxing hunting restrictions in US parks and refuges

After January order from US department of the interior, managers across 55 sites have lifted prohibitions

Donald Trump’s administration is quietly pushing national park, refuge and wilderness area managers to dramatically scale back hunting restrictions, raising questions about visitor safety and the impact on wildlife.

Doug Burgum, the US Department of the Interior secretary, issued an order in January directing multiple agencies to remove what he termed “unnecessary regulatory or administrative barriers” to hunting and fishing, to and justify regulations they want to keep in place.

Airline emissions in Europe top pre-Covid levels despite pledge to decarbonise

Promises to cut emissions and use more fuel-efficient planes fail to stop rise, with Ryanair’s carbon footprint 50% up on 2019

Emissions from flying in Europe have now passed pre-pandemic levels, with Ryanair’s carbon footprint 50% higher than in 2019, research has shown.

Total aviation emissions continue to increase despite industry pledges to decarbonise and the introduction of more fuel-efficient planes, driven by the massive expansion of low-cost carriers.

Up to 2cm a month: Nasa keeps track as Mexico City sinks into the ground

Powerful radar system is providing new data on city’s subsidence, which experts hope will draw more attention to it

Walking into Mexico City’s sprawling central Zócalo is a dizzying experience. At one end of the plaza, the capital’s cathedral, with its soaring spires, slumps in one direction. An attached church, known as the Metropolitan Sanctuary, tilts in the other. The nearby National Palace also seems off-kilter.

The teetering of many of the capital’s historic buildings is the most visible sign of a phenomenon that has been ongoing for more than a century: Mexico City is sinking at an alarming rate.

Fertiliser shortages will have ‘dramatic’ effect on global food prices, warns farming boss

Powerful property and farming firm Grosvenor Group says knock-on effect of Iran war could arrive next year

Fertiliser shortages caused by the Iran war have driven up costs for UK farmers by up to 70% and will have a “dramatic” impact on food prices globally next year, according to one of Britain’s most powerful property and farming companies.

Mark Preston, executive trustee of the 349-year-old Grosvenor Group, controlled by the Duke of Westminster, said fertiliser “was already quite expensive” before the 50% to 70% surge in prices since the start of the Iran war in late February.

Alaska’s 2025 mega tsunami highlights risk to cruise lines as glaciers retreat

Researchers say 481-metre wave in fjord was triggered by rockslide linked to climate crisis

A mega tsunami in Alaska last year in a fjord visited by cruise ships is a stark warning of the risks of coastal rockslides and glacier retreat fueled by the climate crisis, a new study warns.

Scientists recorded the world’s second-tallest tsunami after it struck the Tracy Arm fjord in south-east Alaska last August after a massive rockslide around the toe of a glacier. The tsunami reached 481 metres (1,578ft) in height; by comparison the Eiffel Tower is 330 metres (1082ft).

Norwegian fish farms polluting fjords with waste likened to ‘raw sewage of millions of people’

Exclusive: ‘Fish sludge’ in coastal waters now has nutrient levels equivalent to those in untreated effluent of country the size of Australia, report finds

Norwegian fish farms are filling fjords and other coastal waters with nutrient pollution equivalent to the raw sewage of tens of millions of people each year, a report has found.

Norway is the largest farmed salmon producer in the world, and nutrients in fish feed are excreted directly into coastal waters. Analysis from the Sunstone Institute found that Norwegian aquaculture released 75,000 tonnes of nitrogen, 13,000 tonnes of phosphorus and 360,000 tonnes of organic carbon in 2025.

Weather tracker: Cold spells in Greece and Turkey, and storms in Bangladesh

High winds have hit the South Aegean and heavy rain has fallen in Turkey, but Central Europe has felt summer heat

Greece and Turkey have found themselves in the grip of a late-season cold spell this weekend. Conditions will persist over the next few days as an area of low pressure situated over Turkey is pulling in colder, moisture-laden air from the north-east via the Black Sea; this meteorological set up has suppressed temperatures well below where they should be for the time of year. Away from the Mediterranean coast, much of Turkey struggled to reach double figures, which is around 10C below the average, while Greece saw a similar chill. In Athens, temperatures only crept into the low teens Celsius, a far cry from the mid-20s typically expected in early May.

But they haven’t just faced colder temperatures. Greece had gale force winds whipping through the islands in the South Aegean – gusting at around 60mph on Sunday evening and the unsettled weather has brought a surge of heavy rain to Turkey. The Central Anatolia region of Turkey would normally see about 50mm of rainfall across the entire month of May, but on Sunday had already seen many areas pick up half that total in just 24 hours. With colder air in place, higher elevations have even seen a return to winter, with up to 30cm of fresh snow forecast across the Anti-Taurus Mountains on Monday and Tuesday. In Ankara, temperatures on Monday were expected to peak at just 7C – nearly 14C below average – before slowly edging back towards normal by the weekend.

‘They don’t belong in our environment’: US vineyards battle spotted lanternflies as invasive insects spread

From Virginia to New York, the bugs drain vines, cut yields and leave growers resorting to one simple fix: squash them

Around grape harvest time about three years ago, an employee at Zephaniah Farm Vineyard in Leesburg, Virginia, noticed bugs, about 1in long with gray and black wings and a bright red underwing, atop some trees.

While the insects were pretty, they were there for the grapevines and not welcome guests at the vineyard, which sits atop a farm that the Zephaniah family has run since 1949.
