The global attack on nature is threatening the UK's national security, government intelligence chiefs have warned, as the increasingly likely collapse of vitally important natural systems would bring mass migration, food shortages and price rises, and global disorder. Food supplies are particularly at risk, as without significant increases, the UK would be unable to compete with other nations for scarce resources, a report to ministers warns.

Many of them were built for purposes that no longer exist - cattle drives, mining prospecting, early U.S. Forest Service fire patrols - while others were packed by the footprints of the Chumash people well before the colonization of North America. Sections of trail cling to steep slopes that seem to barely resist gravity, shedding soil and stone with each winter storm.

In the rolling hills of southeast Queensland, Australia, farmer and businessman Brent Finlay stands beneath turbines so tall they rival skyscrapers. "There's a lift inside that takes about 12 minutes to go from the bottom to the top," he said, pointing skyward. Forty-five of the giant turbines that now dot his property are part of the massive MacIntyre Wind Farm which will soon generate enough electricity to power 700,000 homes.

The emissions in our atmosphere are at work, heating the planet, acidifying our oceans, and leading to climate-fueled disasters: heat waves, fires, flooding, droughts, and storms. For some climate impacts, devastation can be followed by the painstaking work of recovery. But for many natural systems, like our tropical coral reefs, the stress we are putting on them is reaching the realms of permanent decline and ultimate collapse.

According to a recent report, the sector is in dire need of an infusion of new blood and must recruit 22,600 younger workers over the coming years as the current generations of growers reach and exceed retirement age. The report, commissioned by the Spanish Wine Interprofessional Organisation (OIVE), found that 38.9% of wine-growers are aged 51-65 and 35% are over 65. Those aged 41-50 make up 16.9% of the sector, while the under-40s comprise only 9.3%.

You think you've made the deal of a lifetime, and it turns out it could have been even better. And at a certain age, those strong emotions can be dangerous, as Mauri Oliveira, a 66-year-old Brazilian coffee producer, can attest to. Owner of the Campestre estate, he speaks with delight about the ritual he shares with other landowners every full moon night. They have dinner at one of the estates before embarking on a horseback ride by the light of the moon along the trails.

2025 was an extremely difficult year for corporate sustainability, especially in the U.S. Core priorities - from cutting carbon emissions and investing in clean tech to building inclusive workforces - were under constant attack, much of it from the government. At one point, the administration even tried to stop the construction of a giant offshore wind farm that was 80% done.

Rikki Held grew up on her family's ranch in Montana, watching the land transform amid the climate crisis. The Powder River, which runs through the property, has sometimes dried up during drought, leaving crops and livestock without water. At other points, rapid snowmelt and heavy rains have caused flooding and eroded riverbanks, making the land difficult to use. Two years ago, the 24-year-old and a group of other young people won a groundbreaking legal victory, intended to prevent those impacts from worsening.

The sign outside Tom Hermes's farmyard in Perkins Township in Ohio, a short drive south of the shores of Lake Erie, proudly claims that his family have farmed the land here since 1900. Today, he raises 130 head of cattle and grows corn, wheat, grass and soybeans on 1,200 acres of land. For his family, his animals and wider business, water is life.

After record-breaking rains, an ancient lake in Death Valley national park that had vanished has returned to view. The temporary lake, known informally as Lake Manly, has appeared once more at the bottom of Badwater Basin, which sits 282ft beneath sea level, in California. The basin is the lowest point in North America, according to the National Park Service. Repeated storms from September through November filled the flat with runoff, forming a thin layer of water.

Researchers have developed a skin-permeable polymer that can deliver insulin into the body, which they say could one day offer an alternative to injections for diabetes management. The skin's structure presents a formidable barrier to the delivery of large drugs but in this work a team show that their polymer can penetrate though the different layers without causing damage. Insulin attached to this polymer was able to reduce blood glucose levels in animal models for diabetes at a comparable speed to injected insulin.

In his memo, Gates posited that climate change "will not lead to humanity's demise." That's true, Hayhoe said, but it's also an unhelpful "straw man" argument, because scientists sounding the alarm on climate change have never argued it will lead to humanity's extinction. Humanity's fate amid the climate crisis is not a binary, she explains, but a question of scale: How much will humanity suffer due to climate change? And how much suffering can we prevent?

A new report from the nonprofit Coffee Watch says that modern coffee production in Brazil continues to be a significant driver of deforestation, with hundreds of thousands of hectares of native forest cleared inside coffee farm boundaries since 2001. Beyond the global implications for biodiversity and climate change, the continued loss of forest in key coffee regions presents economic threats to the Brazilian coffee sector, driving a cycle of drought and yield volatility, according to the report.

Five times stronger than the Gulf Stream and 100 times larger than the Amazon River, the Antarctic Circumpolar Current (ACC) is by far the world's largest ocean current. But this key system is grinding to a halt, a new study has warned. Analysing core samples, scientists from the University of Bonn have found that the ACC has undergone a major slowdown. In fact, the ocean current is now running three times slower than it was 130,000 years ago. Worryingly, if it continues, this dramatic slowdown could have disastrous consequences.

The Guardian has long been at the forefront of agenda-setting climate journalism, and in a news cycle dominated by autocrats and war, we refuse to let the health of the planet slip out of sight. We stand out as a media organisation by examining why the climate emergency is creating a new era of demagogues and how powerful governments, financial institutions and big oil companies are turning their back on climate promises.
