Changing tides have led to an increase of beached marine life, whom rescuers scramble to save before they die

While Cape Cod, Massachusetts, is known as a popular vacation destination in the north-east US, it has built a reputation for an entirely different reason this year: animal strandings.

Dolphins, whales, sea lions and turtles are turning up in large numbers on the beaches of the famous peninsula in a phenomenon that has experts scrambling to execute more rescue operations than ever before. The cause? Changing tides.

Academic Danilo Brozović says studies of failed civilisations all point in one direction – today’s society needs radical transformation to survive

For someone who has examined 361 studies and 73 books on societal collapses, Danilo Brozović’s conclusion on what must happen to avoid today’s world imploding is both disarmingly simple and a daunting challenge: “We need dramatic social and technological changes.”

The collapse of past civilisations, from the mighty Mayan empire to Rapa Nui (Easter Island), has long fascinated people and for obvious reasons – how stable is our own society? Does ever-growing complexity in societies or human hubris inevitably lead to oblivion? In the face of the climate crisis, rampant destruction of the natural world, rising geopolitical tensions and more, the question is more urgent than ever.

Analysis shows fossil fuels are supercharging heatwaves, leaving millions prone to deadly temperatures

The climate crisis caused an additional six weeks of dangerously hot days in 2024 for the average person, supercharging the fatal impact of heatwaves around the world.

The effects of human-caused global heating were far worse for some people, an analysis by World Weather Attribution (WWA) and Climate Central has shown. Those in Caribbean and Pacific island states were the hardest hit. Many endured about 150 more days of dangerous heat than they would have done without global heating, almost half the year.

At least one dead and three missing amid storm that has split wharf, wrecked boat and piled up debris

California residents are being warned to stay off wharves, piers and other waterside structures as 20-30ft waves are expected to batter the northern Pacific coast for the rest of the week.

The National Weather Service advisory comes after a 150ft section of the wharf in Santa Cruz collapsed amid high waves on Monday, and storm debris was blamed for the death of a Santa Cruz county man on a beach in Watsonville.

Belief in a supposed US government plot linked to aircraft condensation trails has been boosted by confusion over proposals to geoengineer a response to the climate crisis

A conspiracy theory that airplanes are leaving nefarious “chemtrails” in their wake due to a sinister government plot has been given fresh impetus in the US amid a swirl of concerns and confusion about proposals to geoengineer a response to the climate crisis.

State legislation to ban what some lawmakers call chemtrails has been pushed forward in Tennessee and, most recently, Florida. Meanwhile, Robert F Kennedy, who has expressed interest in the conspiracy theory on social media and his podcast, is set to be at the heart of Donald Trump’s new administration following his nomination as health secretary.

Rising temperatures are pushing these Arctic mammals ever farther into Greenland’s north. But eventually there will be nowhere left for them to go

Built like a small bison, weighing as much as a grand piano and covered in thick, shaggy coat, the musk ox is one of the most distinctive species in the high Arctic. But from a hill on Greenland’s tundra, they seem impossible to find.

Each bush, rock and clump of grass resembles a mass of wool and horns in the blustery chill on the edge of the island’s enormous polar ice cap. Scanning the shimmering landscape with binoculars, Chris Sørensen looks for signs of movement.

Scientists search for a variety to withstand the climate crisis as high temperatures and drought can stress trees

The climate crisis is increasingly affecting agriculture in the United States, including the production of Christmas trees.

Like all crops, Christmas trees are vulnerable to a changing climate, as the United States continues to experience warmer temperatures, more frequent and severe heat, increased rainfall, droughts, wildfires and hurricanes, as a result of global warming and the climate crisis – primarily driven by humans’ burning of fossil fuels.

Campaigners say consumption such as travel, gifts and food are destroying planet and the meaning of Christmas

Whether out of poverty or virtue, many of us spend much of the year reining in our appetites to save our pennies and our health. But at Christmas many of us put our worries aside and go wild in an orgy of lavish gifting, extensive travel and a gluttonous feeding frenzy.

This carnival of consumption has a cost: not just to our wallets and our waistlines, but also to the climate.

With restrictions due next month, food vendors are still using such plastics and some traders have not heard of ban

Labake Ajiboye-Richard, the founder of a Lagos-based sustainability consultancy, was driving in Nigeria’s most populous city earlier this month when she saw someone throwing rubbish out of their car window.

“I was so shocked to see that in 2024,” she said. “If you’re throwing something on the road, what are you doing in your home? What are you doing in your community?”

While some residents take to building houses in trees, officials recognise need for national response to climate disasters

Every summer, Dongting Hu, China’s second-largest freshwater lake, swells in size as flood water from the Yangtze River flows into its borders. Dams and dikes are erected around the lake’s edges to protect against flooding. But this year, not for the first time, they were overwhelmed.

For three days in early July, more than 800 rescue workers in Hunan province scrambled to block the breaches. One rupture alone took 100,000 cubic metres of rock to seal, according to Zhang Yingchun, a Hunan official. At least 7,000 people had to be evacuated. It was one of a series of disasters to hit China as the country grappled with a summer of extreme weather. By August, there had been 25 large floods, the biggest number since records began in 1998, reported state media.
