Free-roaming Aldabra population far exceeds human population of Seychelles after decades-long recovery programme

A survey of the world’s largest free-roaming giant tortoise population has discovered that the once endangered species is thriving.

A population of Aldabra giant tortoises lives on an island in Seychelles called Aldabra Atoll.

Complaints risks putting defence ministry on collision course with Department for Energy Security and Net Zero

The Ministry of Defence has objected to at least four planned windfarms in the past year over fears the spinning blades could cause “unacceptable interference” with radars used to detect military aircraft.

MoD officials raised concerns in late June over plans for an onshore windfarm in County Durham that could result in aircraft “not being detected” within an RAF Low Flying Area, according to a letter to Britain’s planning authority.

A new global biodiversity report strikes an encouraging note. But we cannot rest on our laurels – and resilience is key

The new Living Planet Report is out. Published every two years, it assesses the health of the natural world and, historically, it’s made for gloomy reading.

Take 2024’s report, which showed global wildlife populations had plummeted by 73% in 50 years and that ecosystems were being pushed toward collapse.

Claudia Galeno-Sánchez has turned her home into a sanctuary for the insects by planting native milkweed and wildflowers – and sharing her experience

Along the concrete streets of Chicago’s Pilsen neighborhood, a vividly colored home stands out among the rest.

Over the past few years, Claudia Galeno-Sánchez has transformed her modest family home, which she shares with her husband and two children, into a sanctuary and educational space dedicated to the monarch butterfly.

Galeno-Sánchez painted her home with the help of neighbors, her kids, and the renowned muralist and painter Héctor Duarte.

Devastating blaze near Sizewell B nuclear power station in Suffolk among a record 624 wildfires in July this year

This July was the worst on record for wildfires in England, provisional data shows, with England experiencing a clear upward trend in the total number of wildfires recorded.

This summer has been a stark reminder of the vulnerability of the UK to climate breakdown, after punishingly hot and dry weather turned large parts of the countryside into a tinderbox.

Nine out of 10 people felt motivated to act after watching film outlining threats to food security, economy and public health

The British government must be honest about the scale of the threat posed by climate and nature breakdown, researchers have said, after nine out of 10 people surveyed after watching a briefing on the issue felt more motivated to act.

Last November, in the “first-of-its-kind national emergency briefing”, nine experts gave stark assessments in Central Hall in Westminster of the scale of the changes needed in the UK to adapt to the rapidly changing climate and ecological landscape.

The UK state is dumping its responsibilities on our doorsteps, while green-lighting policies that lead us closer to crisis

Would you mind fixing the NHS? And while you’re at it, could you please build an anti-missile system in your garden? Then regulate the banks, replace the water mains, tax the very rich and use the proceeds to rebuild our schools. Well, come on people: what are you waiting for?

I exaggerate, but this isn’t very far from the approach taken by the government’s Prepare campaign. Crucial functions, way beyond the scope of individual action, are dumped on our doorsteps while those in power fail to act. As a result, our national resilience is arguably lower than at any time since the second world war. At the Labour conference last week, Andy Burnham promised “a Britain where people feel the country has got their back again”. To make good on that pledge, he will have to change almost everything.

The Norwegian government has given a permit to a mining company to release waste into Førde fjord despite a 17-year battle by campaigners and a supreme court ruling against it

Shortly after the Norwegian stock market closed on 17 June 2026, a few dozen local people from the small west coast town of Vevring crowded around a laptop in a school. Surrounded by children’s drawings and windows looking out over Førde fjord, they listened as news arrived from Oslo. Norway’s supreme court had ruled against its government: a permit to release mining waste directly into the fjord two miles upstream was illegal, the court said.

The moment marked the end of a 17-year fight, one of Norway’s most protracted environmental battles in living memory. In Oslo, Ingvild Fonn Asmervik, the project leader for Naturvernforbundet (Friends of the Earth Norway), compared the joy she felt to giving birth to her child. For Anne-Line Thingnes Førsund, a third-generation fisher living on the banks of the fjord in Vevring and a volunteer for the charity’s local branch, it was more of a relief. Like a mountain lifting off her shoulders, she said.

Hundred-and-fifty-year-old Wych elm in Newcastle, Co Down has grown sideways owing to strong winds

The “astonishing and bizarre” Bendy Tree in Northern Ireland has been crowned the winner of this year’s tree of the year competition.

The wych elm tree, located in Newcastle, County Down, owes its name to its near horizontal trunk, which has grown sideways owing to the strong seaside winds coming off the Irish Sea.

Recovery of tigers, tuna and green sea turtles show nature loss can be reversed when action taken, charity says

Conservation comebacks for wild tigers, tuna and green​ sea turtles prove that global nature loss can be reversed, ​scientists have said. ​But a report warns food production must be the next ​“positive tipping point​” if the world is to avert biodiversity collapse.

The World Wildlife Fund (WWF) analysed nearly 36,000 animal populations and more than 5,000 species, producing the largest ever database of vertebrate wildlife. Scientists found populations had declined by an average of 73% since 1970, showing that “nature continues to be degraded at an alarming scale”, with “no sign of losses slowing”.

Inquest under way into why President Lula’s success in curbing Amazon deforestation has not led to success at polls

More fire, more ash, more crime, more death. And a globally important ecosystem driven ever more rapidly towards a point of no return. That is the prospect for the Amazon rainforest for at least the next four years if Flávio Bolsonaro holds on to the lead he established this week in the first round of Brazil’s presidential election.

This appears to be of far more concern to the outside world than to voters in Latin America’s biggest, richest and most biodiverse nation.

Guardian reporters Jonathan Watts and Gabrielle Canon answered your question climate and extreme weather, from what to expect this winter in the UK to the increasing risk of natural disasters

funkymentalist asks: Unrelated to El Niño, what is the likelihood of the AMOC (Atlantic meridional overturning circulation) shutting down?

Jon says: I don’t think these two things are unrelated. Everything is affected by climate breakdown. And both El Niño and the slowdown of AMOC are related to the staggeringly huge amounts (see this article on zettajoules which I also referred to above) of extra energy that the oceans are being forced to absorb as a result of greenhouse gas burning.

Quick refresher for any readers who are unfamiliar with this topic: “Amoc, or the Atlantic meridional overturning circulation, is a system of ocean currents that brings heat into the northern Atlantic. Warm surface water from the tropics flows north and releases its heat in the subpolar Atlantic, south of Greenland and west of Britain and Ireland. Then it cools and sinks to a depth of between 2,000m to 3,000 metres before returning south as a cold current. Amoc is one of our planet’s largest heat transport systems, moving the equivalent of 50 times the human energy use, and it has a particularly strong impact on the climate in Europe, affects the ocean’s CO2 uptake and oxygen supply, as well as rainfall patterns in the tropics.”

Gaby says: The name “El Niño” actually harkens back to long before forecasters used the phenomenon to track global weather patterns. Fishermen off the coast of South America began to track unusually warm water that would show up every few years right around Christmas - thus “The Little Boy” referring to the Christ child in Spanish. Scientists adopted the name, and added “La Niña” as its counterpart (when sea surface temperatures cool), and together they became ENSO - the El Niño Southern Oscillation. This year, though, feel free to call it “El Monstruo Gordo!” It’s going to be a big one.

A mix of natural disasters could all befall the state at once as it finds itself in the crosshairs of the climate phenomenon

On a cloudless autumn afternoon, sunlight sparkled on the water that had quietly swallowed a busy intersection to the north of San Francisco, as the surrounding rush-hour traffic slowed to a painful crawl.

There were no crashing waves or storm surges to blame for the flood. Marin county was one of many areas up and down the California coast affected by high tides last week, as parts of the Pacific swelled with excess warmth.

A farm labor contractor exposed laborers on H-2A agricultural visas to heat-related health hazards, but is still bringing hundreds of migrant farm workers to North Carolina

It was 4pm and 90F (32C) when Carlos Vargas Moreno and other farm workers set out to weed a watermelon field in Goldsboro, North Carolina, on 19 July 2022.

The work day had begun at 7am and included two 15-minute breaks and a one-hour lunch eaten outdoors. The heat index – what the temperature feels like to the human body when relative humidity is combined with the air temperature – was 98.3F. It was the kind of day that a heat safety app created by the Occupational Safety and Health Administration (Osha) and the National Institute for Occupational Safety and Health (Niosh) defined as “hazardous” for outdoor workers.

As well as books, the new facility in Colorado offers equipment to help connect people with the natural world. We asked five of the first visitors what they thought of it

Mark Fink knows exactly why he opened the first public nature library in the US. “There are a lot of barriers for people to access nature here. We want people to learn about the birds and the plants in their own back yard and to appreciate that you don’t need a three-day camping trip in the mountains to experience nature.”

The library offers people in Colorado’s Adams county the opportunity to borrow books and equipment to help them to engage with the natural world – for free.

Ruling on Mount Pleasant coalmine shows ‘we cannot continue to dig up coal … and pretend the consequences have nothing to do with us’, group says

A Hunter Valley community group has won Australia’s first high court case to consider climate change, in a ruling advocates say sets a binding national precedent for fossil fuel projects in New South Wales.

In a landmark judgment, the nation’s highest court ruled that the approval of MACH Energy’s Mount Pleasant coalmine expansion in Muswellbrook was invalid.

Government report finds the country could be hit with more frequent and intense heatwaves, as well as damaging storms and cyclones

New Zealand could be hit with more frequent and intense heatwaves and catastrophic glacier melts in the near future, as greenhouse gas levels hit record highs, a new report about the nation’s climate has revealed.

Released on Wednesday, the Our Atmosphere and Climate 2026 report shows New Zealand is experiencing mounting climate pressures, which will have wide-reaching implications for the environment, native species and communities.

Service to be tested in Spain and Portugal this year, with a UK rollout if successful, as pre-loved markets boom

Ikea is to test an online version of its buy-back service where the retailer offers vouchers for unwanted secondhand furniture.

The service will be tested in Spain and Portugal before the end of December and will be launched in the UK if it proves successful. Ikea already offers buy-back in stores, including in the UK. The online version will extend it to a much wider audience, with Ikea predicting pre-owned goods are likely to grab 16% of the UK homewares market by next year

John Murdock had been working for the agency for 18 years and his resignation comes during an exodus of longtime federal workers and scientists

An 18-year veteran of the US Department of the Interior has resigned in protest from the sprawling federal agency, denouncing “a deeply troubling assault on the rule of the law” that took place at the department under Donald Trump.

John Murdock, an attorney and self-described conservative Christian, began working for the agency’s legal office in 2002. In his resignation letter, first sent to his supervisor earlier this year and obtained exclusively by the Guardian and Public Domain, Murdock cites “glaring legal flaws” he witnessed within the agency during the course of the Trump administration, as well as concerns over offshore oil and gas drilling, the aggressive push to expand fossil fuels and the flouting of environmental regulation.

Prime minister tells delegates in Tuvalu and Fiji that ‘super El Niño’ brewing in the Pacific shows climate change is ‘here right now’

Anthony Albanese has warned Australia faces a hazardous summer, likely including floods, cyclones and extreme heat, due to the immediate threat of climate breakdown and a rising “super El Niño”.

Speaking alongside national leaders at a climate summit in Fiji, the prime minister said the expected nasty summer and the demonstrated impact on Pacific island countries – including low-lying Tuvalu – showed the world could not afford to let the goal of limiting global heating to 1.5C “just slip from our grasp”.
