Exclusive: Fixing a leak can be simple and equivalent to closing a coal power station, making lack of action maddening, say analysts
The world’s worst mega-leaks of the potent greenhouse gas methane in 2025 have been revealed by an analysis of satellite data.
The super-polluting plumes from oil and gas facilities have a colossal heating impact on the climate but often result from poor maintenance and can be simple to fix. The assessment found dozens of mega-leaks, each having the same global heating impact as a coal-fired power station.

Our photojournalist explores the Cornish landmark on the eve of its anniversary and meets some of its staff, visitors, plants and creatures
“Give me a sleeping bag and I’ll happily sleep here overnight,” says Kim Mackintosh as she wanders amid the vibrant flora of the Mediterranean biome at the Eden Project on the eve of the tourist attraction’s 25th anniversary.
Loupe in hand, the leader of the biome’s horticulture team is marvelling at an array of plants that have recently come into bloom, tenderly examining the yellow furry buds of an Acacia glaucoptera before flogging a Grevillea flower to dispense its rich, honey-flavoured nectar.

Fearing that extreme weather threatened its epic breaks, Oriente Salvaje is piloting the first surf insurance policy to protect livelihoods and ecosystems
In the late 1990s in El Salvador, Rodrigo Barraza went in search of every surfer’s dream: a pristine wave, far from the crowds. Down a rough dirt track hours from any city, he found it: a little-known surf spot on the country’s eastern shores, where long lines of waves form a crisp right-hand break, surrounded by thousands of hectares of tropical forest.
“I fell in love with the place,” says Barraza. In 2004, he opened a small hotel there, and along with some surfing friends, founded a tourism association. They developed sustainable tourism standards and committed to protect the surrounding biodiverse ecosystemof rare dry tropical forest, rivers and mangroves. They called it Oriente Salvaje – the “wild east”.
Oriente Salvaje is known by surfers for its world-class breaks, Las Flores and Punto Mango

This year, Guardian Live events will host the Guardian Climate Forum 2026, a live gathering focused on discussing solutions, accountability and the shared task of building a greener, fairer future. And we want to shape this landmark event with your help
The climate crisis is one of the defining challenges of our age. But it is also a story of ingenuity, resilience and collective action. Across the world, communities are rethinking energy, food, transport and finance. Campaigners are holding power to account. Scientists are pushing the boundaries of what’s possible. Change is happening and the conversation about what comes next belongs to all of us.
We’d like to hear from you:
Which climate issues feel the most pressing where you are, and which give you hope?
What solutions, ideas or grassroots initiatives deserve deeper exploration?
Who would you most like to hear from, and whose perspectives are we missing?
What stories about climate progress, innovation or accountability are underreported?
What would make an event on climate feel constructive, inspiring and genuinely useful?

Drosopigi, the Mani, Greece: This rocky region’s abundance of flora takes the breath away – not least a long and winding trail of Chios chamomile
The Greek name for this southernmost tip of the Peloponnese is linked to a Byzantine fort at Cape Tigani (called Megali Maina), but it may well also draw on the region’s desolate, mountainous rocky country that persists throughout the entire peninsula.
The fierce Maniot people were well described by Patrick Leigh Fermor in his book Mani (1958), but the region has been more recently celebrated in Charles Foster’s brilliant The Edges of the World, published in January. In history the Mani was known variously for the relentless and sometimes centuries-long vendettas between its local clans, as a fertile recruiting ground for Mediterranean piracy and as an early outpost for Greek liberation from Ottoman rule.

Researchers project that reduced activity could contribute to half a million additional premature deaths annually by 2050
Rising temperatures are making physical activity undesirable and even dangerous in many parts of the world, and as global heating worsens, it will further affect how much people are able to move.
Researchers analysed data from 156 countries between 2000 and 2022 and modelled how rising temperatures may affect physical activity globally by 2050.

Perhaps the biggest surprise is that it tricks ants into moving its seeds with a scent that mimics their larvae
Plants are superb at enticing animals to pollinate their flowers or carry off their seeds. But one plant co-opts an astonishing combination of fire, bees and ants to mastermind its reproduction.
The South African Natal crocus, Apodolirion buchananii, has a gloriously bright white flower that emerges from the ground before its leaves appear in early spring. But the flower only blooms shortly after fire breaks out naturally in its native grasslands, leaving it standing like a beacon among the blackened grass to help lure bee pollinators, with an irresistible sweet scent that wafts through the air.

As the hit travelogue about the worlds beneath us becomes a film, its maker takes us on a voyage through Las Vegas storm drains and the caves of Yucatán – via Goatchurch Cavern in the bowels of Somerset
Just off the B3134 in Somerset is a portal to the underworld. The smaller of two openings to Goatchurch Cavern, it’s called the Tradesman’s Entrance – and through it I am squeezing. After tumbling on my bum over damp smooth rock, lacerating a jumpsuit in the process, I venture down and down, sometimes crawling, sometimes standing upright, trying to find footholds in the dark.
I’m here with film-maker Robert Petit, so he can show me something of what he’s been experiencing for the past five years, on his way to making an endearingly poetic documentary film called Underland, which riffs on nature-writer Robert Macfarlane’s bestselling 2019 subterranean travelogue of the same name. We’re heading 100ft underground to the Boulder Chamber where, over sugary snacks, I will quiz him about his obsession.

The detection at a popular park of ‘one of the worst invasive species to reach Australia’ is causing concern that suppression efforts are cracking
The Newmarket women’s football side was gearing up for its clash against crosstown club New Farm United in Brisbane’s inner northern suburbs on Saturday morning when a message pinged in the team’s group chat.
Just hours before kick-off, the game was postponed, to a date undetermined.
