The current fires in Los Angeles are reminders of the costs of forgetting

The fires raging in and around Malibu are huge, and they’re terrible, and they’re also the latest in a series of catastrophic fires in Los Angeles county and the region, the latest consequence of heat and drought and wind that have long created the region’s volatile fire weather.

The climate crisis has made it hotter and drier and made wildfire worse here and across the west and around the world, but this region’s ecology has always been wedded to fire. Homes built in and around natural landscapes – canyons, chaparral coastal hills, forests, mountainsides – with a history of wildfire that are pretty much guaranteed to burn again sooner or later create the personal tragedies and losses and the pressure for fire crews to try to contain the blazes. But suppressing the blazes lets the fuel load build up, meaning that fire will be worse when it comes.

With 2024 set to go down as the hottest year on record, we know that what is coming is truly horrifying

The past 12 months have seen our world enter new territory. Last year will go down as the first time that the global average temperature exceeded 1.5C above preindustrial times over a calendar year. We could crash permanently through the 1.5C guardrail within the next five years, and shatter the 2C limit as soon as 2034. This will almost certainly result in the tipping points for collapse of the Greenland and west Antarctic ice sheets being crossed, committing us to the drowning of coastal towns and cities.

In years to come, we will look back at this time and ask the same question that future generations will ask: why didn’t we stop this catastrophe?

Steve Reed says planning rules ‘have got in the way’ of farmers and apologises for ‘shock’ of inheritance tax change

• UK politics live – latest updates

Labour’s proposal to loosen planning regulations for farmers will deluge rivers with chicken faeces, environmental campaigners have warned.

The environment secretary, Steve Reed, promised farmers on Thursday they would be able to build larger chicken sheds, but experts have said this would create “megafarms” and contribute to river pollution.

Rystad Energy releases data days after Ukraine stopped flows of Russian gas through its pipelines

Europe bought a record amount of liquefied natural gas from Russia last year, data shows, despite EU efforts to ditch the fossil fuels funding Putin’s war chest.

Ships carrying 17.8m tonnes of ultra-cold Russian gas docked in European ports in 2024, up by more than 2m tonnes from the year before, according to analysts Rystad Energy.

Environment secretary Steve Reed urged to bring in ‘full and swift ban’ to protect health of people, wildlife and pets

Wildlife charities have called on the government to ban the sale and use of lead in ammunition used for outdoor shooting.

The Wildfowl & Wetlands Trust (WWT), RSPB, Wildlife and Countryside Link, Chem Trust and Wild Justice have sent an open letter to the environment secretary, Steve Reed, asking for a 18-month transition period for a ban on lead in ammunition sales.

Conditions for a January LA firestorm have not existed before now, writes a meteorologist and climate journalist

An exceptional mix of environmental conditions has created an ongoing firestorm without known historical precedent across southern California this week.

The ingredients for these infernos in the Los Angeles area, near-hurricane strength winds and drought, foretell an emerging era of compound events – simultaneous types of historic weather conditions, happening at unusual times of the year, resulting in situations that overwhelm our ability to respond.

A failure of justice, and draconian Tory law, put Gaie Delap in prison. A failure of government is keeping her there

Gaie Delap will turn 78 on Friday, in Eastwood Park prison, Gloucestershire. Sentenced to 20 months last August for climbing a gantry over the M25 for Just Stop Oil, she was released in November to serve the rest of her sentence on a home detention curfew. But the electronic tag that she was required to wear couldn’t go round her ankle because she has deep-vein thrombosis and it might have risked causing her a stroke. It couldn’t go round her wrist because they couldn’t find a tag small enough, which people keep saying is because she’s frail. Delap hates being called frail. Her wrist is a perfectly reasonable size, 14-and-a-half centimetres. It’s the wrist-tag design that’s wanting. The topsy-turvy world where a government contractor, Serco, can fail and fail again, while a citizen with a social purpose gets called back to prison five days before Christmas to atone for that failure, isn’t even the most absurd thing about this story.

Delap was engaged in direct action to raise awareness about the climate emergency, and the day citizens stop doing that is the day that progressive politics might as well give up and go home. Whatever pretzel twists Labour ministers have to perform to sound as if they’re on the side of the decent, honest commuter, while simultaneously signalling that they understand the scale of the climate crisis, they must surely remember this: the trade union movement, the peace movement, the suffragette movement, the civil rights movement, the climate justice movement; every known movement of change has relied on non-violent action to disrupt the status quo.

Hollywood stars once came for the big-game fishing, but the return of a host of species to the depleted waters around Britain’s coast is a cause for quiet optimism

From the outside, the Tunny Club looks like any other seaside fish and chip shop. A short walk from Scarborough harbour, only the photos of John Wayne and Errol Flynn on the wall betray the shop’s fleeting history as a global centre for big-game fishing.

In the 1930s, film stars and the ultra-wealthy flocked to the Yorkshire seaside resort for their chance to catch the enormous bluefin tuna – known as “tunny” – lurking off the North Sea coast. In 1933, aristocrat Lorenzo Mitchell-Henry reeled in what remains the largest fish ever caught in British waters: a 386kg bluefin tuna.

Wildfires continued to burn across LA, with at least five people killed and more than 1,500 buildings destroyed. A new blaze broke out in the Hollywood Hills and evacuation orders were extended to Santa Monica. Winds had eased, but the danger was far from over

• At least five dead as firefighters struggle to contain LA blazes

Firefighters said the destruction from the California fires was unlike any they had seen in their decades-long careers

• California wildfires – live

The sun glared red as it sank into the Pacific Ocean on Wednesday, casting an orange hue over the carnage smoldering on the southern Californian coast. It will be a day not soon forgotten in Los Angeles, which by evening was flanked by catastrophic wildfires in nearly all directions.

It’s too early to determine the full extent of the destruction caused by the blazes, but in the neighborhoods bordering the Palisades fire it was clear the impact was enormous.

Wildfires continued to grow in Los Angeles as overtaxed fire crews battled three major out-of-control blazes that have killed at least five people. The largest and most devastating so far have been the Palisades fire and the Eaton fire, but other blazes, particularly the growing Hurst fire and the Hollywood Hills-based Sunset fire, are continuing to worry Los Angeles residents

Huge wildfires roaring through the Los Angeles area of Pacific Palisades has left the neighborhood in ruins. Resident Sanah Chung left his Pacific Palisades home when a mandatory evacuation order was placed but returned to protect his home from the fire. 'I know this looks pretty stupid, but If I can save one ember from burning down my house, I'll take the risk,' said Chung.

There are significant health benefits to trying new things, whatever the activity – and there is always more to learn

There is a paradox to being 20 metres under the ocean. It is a place of calm and wonderment. I am immersed in a foreign world, with a new watery sky above me. There is a sense of serenity, blissful peace as countless colourful fish glide past.

Only the tranquillity is deceiving. As a novice diver, my mind ticks over in hyperdrive. All that stands between me and an agonising fate is the tank of compressed air on my back (and, hopefully, the dive guide’s spare air).

This year is on track to be the hottest in recorded history. With rising temperatures and more intense and frequent heatwaves, keeping cool in summer will get harder. Air conditioning can only go so far, especially when extreme heat raises the risk of electricity outages.

Wearing light, loose-fitting clothing is well recognised health advice to beat the heat in sweltering temperatures, especially important given that heatwaves kill more people than any other extreme weather event.

Marauding gangs and political unrest since October’s polls have driven thousands of Mozambicans across the border into Malawi, despite its drought, food and fuel shortages

On a sunny Saturday afternoon, Manase Madia, 50, shows his Mozambican identity card. Once a sign of pride, he does not know what to believe in any more. Over the past few weeks he has seen houses being burned down, and shops and businesses looted, including his own. He now fears for his family, which has scattered.

At a community ground where officials are processing new arrivals before being transferred to a shelter, Madia is one of about 13,000 people who have crossed into Malawi in the past two months, seeking refuge from post-election violence in Mozambique. The arrival of the refugees, albeit in smaller numbers, is reminiscent for people here of the civil war when almost a million Mozambicans sought refuge in the neighbouring southern African nation in the 1980s and early 1990s.

The tiny nation of Niue has raised £3m selling sponsorship of its marine protected area at just over £100 for a square kilometre

Niue, also known as the Rock of Polynesia, is one of the tiniest island states in the world. It takes a mere two hours to drive around it, giving views of its rugged limestone cliffs and occasional sandy coves. These coves give way to caves and chasms, once used for storage, burial sites and even as living spaces. But perhaps what visitors seek most are its crystal clear waters, home to spinner dolphins, eels, grey reef sharks, sea snakes and humpback whales.

Now the island is engaged in an innovative plan to try to conserve these vast and pristine territorial waters. The scheme, which has been running for a year, involves selling off sponsorship of the ocean surrounding the island to individuals or companies for NZ$250 (£116) a square kilometre. So far, it has raised NZ$7m, nearly halfway to its target.

A growing number of landholders are joining forces with right-to-roam campaigners to boost public access to the countryside

When Debra and Tom Willoughby first arrived at their tenant farm in Nottinghamshire, they tried to reroute a bridleway that runs through their farmyard. Now the organic farmers are relieved they were refused permission because of the benefits they have found from the connections they make with people who walk through their farm. They have since opened new permissive footpaths on their land.

Farmers are often cast as vociferous opponents of wider access to the countryside. But a growing band of access-friendly farmers has joined forces with the Right to Roam campaign and will discuss how to open up more land for public enjoyment at this week’s Oxford real farming conference.

British chef Mike Keen paddled up the coast of Greenland eating only what local people did, and the health benefits led him to question the global food system

For a period of two months last year, a typical day for chef Mike Keen would see him skipping breakfast and lunch in favour of snacks such as dried capelin (a small bait fish), dried halibut, jerky-like dried whale and a local Greenlandic whale skin and blubber treat called mattak.

Exploring the aberration, absurdity, madness and ingenuity of skiing, an activity that raises both questions and concerns despite its global success. It continues to fascinate and intrigue in the face of social and environmental upheavals. There are more than 2,000 resorts scattered across the world, attracting hundreds of millions of skiers, but there are also profound questions about its future amid climate challenges and societal changes

As people have shaped the natural world, so wildlife – from mahoganies to magpies – has had to evolve to survive

From the highest mountains to the depths of the ocean, humanity’s influence has touched every part of planet Earth. Many plants and animals are evolving in response, adapting to a human-dominated world. One notable example came during the Industrial Revolution, when the peppered moth turned from black and white to entirely black after soot darkened its habitat. The black moths were camouflaged against the soot-covered trees, surviving to pass on their genes to the next generation.

As human influence has expanded, so too have the strange adaptations forced on the natural world. We asked researchers around the world for similar changes they have noticed in the 21st century.

Experts say sighting of orca in Puget Sound with second deceased calf is ‘devastating’ for ailing population

An apparently grieving killer whale who swam more than 1,000 miles (1,600km) pushing the body of her dead newborn has lost another calf and is again carrying the body, a development researchers say is a “devastating” loss for the ailing population.

The Washington state-based Center for Whale Research said the orca, known as Tahlequah, or J35, was spotted in the Puget Sound area with her deceased calf.

Across Toronto, a team sets out at dawn to rescue migrating birds that have collided with buildings, and keep a record of the thousands each year that don’t make it

Every morning at dawn, a dozen volunteers scour the streets of Toronto picking up small birds. Some days they will find hundreds of them, most already dead or dying. A few they are able to save. Live birds are put in brown paper bags and driven to wildlife recovery centres, while dead birds are put in a large freezer. If no one picks them up, their carcasses are swept up by street cleaners.

“One of my first days was really horrific,” says Sohail Desai, a volunteer with the charity Fatal Light Awareness Program (Flap) Canada, which has about 135 people patrolling the streets across Toronto. Desai was walking close to his house in the North York area in Toronto when a flock of golden-crowned kinglets flew into a 15-storey glass building.

Bowhead whales may not be the only species that can live to 200 years old. Researchers have found that the industrial hunting of great whales has masked the ability of these underwater giants to also live to great ages

In Moby-Dick, Herman Melville’s epic novel of 1851, the author asks if whales would survive the remorseless human hunt. Yes, he says, as he foresees a future flooded world in which the whale would outlive us and “spout his frothed defiance to the skies”.

Moby Dick was a grizzled old sperm whale that had miraculously escaped the harpoons. But a new scientific paper is set to prove what oceanic peoples – such as the Inuit, Maōri and Haida – have long believed: that whales are capable of living for a very long time. Indeed, many more than we thought possible may have been born before Melville wrote his book.

I wind my thread around their holes to create sculptures that connect with ageing and time

I have collected hundreds and hundreds of broken shells. I select them by holding them up to the sea, looking at the shape of them and deciding whether I want to work with them – and whether they will work with my thread.

To me, a shell that is broken is more interesting than a shell that is perfect. A broken shell has lived a life. I can see what the sea has done to it, what has happened to it on the rocks and stones. We spend so much of our lives searching for or trying to obtain perfection. But as I’ve got older, I’ve realised that perfection is unattainable – and the search isn’t worth it.

Part of an international initiative to combat organised wildlife crime, similar seizures in Australia and Norway have recovered more than 50,000 eggs

More than 6,000 eggs have been seized in the biggest haul of its kind in UK history, after police carried out raids in Scotland, South Yorkshire, Essex, Wales and Gloucester. Thousands of eggs were found secreted in attics, offices and drawers.

The UK raids took place in November as part of Operation Pulka, an international effort to tackle organised wildlife crime – specifically the taking, possessing and trading of wild birds’ eggs. The raids began in June 2023 in Norway, and resulted in 16 arrests and the seizure of 50,000 eggs. In Australia, an estimated 3,500 eggs have been seized, worth up to A$500,000 (£250,000).

Grey seals are growing in numbers on England’s east coast as a result of environmental safe havens and cleaner North Sea waters

It is a cold winter’s day to be lying on a beach, but the seal pup suckling from its mother doesn’t mind. A few metres away, a pregnant seal is burrowing into the sand, trying to get comfortable, while a third seal, which has just given birth, is touching noses with her newborn pup.

The shoreline – a mass of seals and their white pups – is one of Britain’s greatest wildlife success stories: a grey seal colony on the east Norfolk coast.
