2021 was New Zealand’s hottest year on record

Experts say we can expect more of the same, with 2021 beating all records since 1909

Last year was New Zealand’s hottest year on record, according to the country’s National Institute of Water and Aeronautic Research (NIWA), and seven of the past nine years are among New Zealand’s warmest ever. The country’s steadily rising temperature brings increased risk of major floods, bushfires and storms.

According to NIWA, New Zealand’s average temperature in 2021 was 13.56 degrees Celsius. It’s the highest average NIWA has recorded since it began its seven-station annual temperature series in 1909, and breaks the previous record set in 2016 by 0.11 degrees.

Meet Mr Trash Wheel – and the other ingenious tools that eat river plastic

From ‘bubble barriers’ to floating drones, a host of new projects aim to stop plastic pollution before it ever reaches the ocean

The Great Bubble Barrier is just that – a wall of bubbles. It gurgles across the water in a diagonal screen, pushing plastic to one side while allowing fish and other wildlife to pass unharmed.

The technology, created by a Dutch firm and already being used in Amsterdam, is being trialled in the Douro River in Porto, Portugal, as part of the EU-supported Maelstrom (marine litter sustainable removal and management) project.

Polar priest: the church in the world’s northernmost town – a photo essay

Photojournalist Giuia Besana visits the world’s northernmost priest who runs the Svalbard Church in Longyearbyen, in Norway’s Svalbard archipelago. Pastor Siv Limstrand is the community’s guiding figure as it looks to an uncertain future in the face of economic shifts and the effects of climate change

Located in the Svalbard archipelago in Norway, Longyearbyen is the world’s northernmost settlement. Here, winter temperatures range from -13 to -20C and inhabitants are prepared for two and half months of complete darkness in winter, the constant danger of polar bears, and avalanches.

Don’t Look Up: four climate experts on the polarising disaster film

Critics haven’t been kind to Adam McKay’s eco-satire, but many climate experts are lauding it. Here four give their views

Rarely has a film been as divisive as Adam McKay’s climate satire Don’t Look Up. Although it has been watched by millions, and is already Netflix’s third most watched film ever, the response from critics was largely negative. Many found its story of scientists who discover an asteroid heading for Earth a clumsy allegory for the climate crisis, while others just found it boring. But many in the climate movement have praised the film, and audience reviews have been generally positive.

We asked four climate experts to give their views on the film. Warning: spoilers ahead.

‘They want to remove us and take the rock’, say Zimbabweans living near Chinese-owned mines

As companies extract wealth, villagers say they see little benefit and are instead exploited in quarries, live in homes damaged by blasts and are unable to farm polluted land

A convoy of trucks laden with huge black granite rocks trundles along the dusty pathway as a group of villagers look on grimly.

Every day more than 60 trucks take granite for export along this rugged road through Nyamakope village in the district of Mutoko, 90 miles east of Zimbabwe’s capital, Harare.

‘Ghost’ orchid that grows in the dark among new plant finds

Hundreds of new species include pink voodoo lily and an ylang-ylang tree named after Leonardo DiCaprio

A ghost orchid that grows in complete darkness, an insect-trapping tobacco plant and an “exploding firework” flower are among the new species named by scientists in the last year. The species range from a voodoo lily from Cameroon to a rare tooth fungus unearthed near London, UK.

A new tree from the ylang-ylang family is the first to be named in 2022 and is being named after the actor and environmentalist Leonardo DiCaprio. He campaigned to revoke a logging concession which threatened the African tree, which features glossy yellow flowers on its trunk.

‘I kept saying – don’t worry Luma, we see you’: Andrea Arnold on her four years filming a cow

The Oscar-winning director’s new documentary explores warmth, joy and anger through the eyes of a farmyard animal. She reveals what it taught her about life

Andrea Arnold’s films are known for their spare dialogue, and in her first documentary it is more pared-backed than ever: Cow consists of 94 minutes of moos, with the odd off-camera interjection from farmhands. It is hardly a thriller (though the ending is pure Tarantino). But it is one of the most beautifully crafted and tender portraits of a life you are likely to see.

Arnold, who started her professional life as a rollerskating TV presenter on the children’s Saturday show No 73, began thinking about documenting an animal’s life nine years ago. Eventually she settled on a cow. “I thought a cow would be interesting because they work so hard, getting pregnant and giving milk their entire lives. It’s a huge job they do.” She chose Luma because she was told she had a big personality and was feisty. Arnold and her team spent four years, on and off, filming her. Why did she make Cow? “I wanted to show a non-human consciousness. I was intrigued as to whether we would be able to see her consciousness if we followed her long enough.”

Rocky road: Paraguay’s new Chaco highway threatens rare forest and last of the Ayoreo people

Forced from their homes by missionaries, the Ayoreo cling on in the Chaco. Now the Bioceanic Corridor cuts through the fastest-vanishing forest on Earth, refuge of some of the Americas’ last hunter-gatherers

In 1972, Catholic missionaries entered the Chaco forest of northern Paraguay and forced Oscar Pisoraja’s family, and their nomadic Ayoreo people, to leave with them. Many perished from thirst on the long march south. Settled near the village of Carmelo Peralta on the Paraguay River, dozens more died from illnesses. Still, the survivors kept up some traditions – hunting for armadillos; weaving satchels from the spiky caraguatá plant. “We felt part of this place,” says Pisoraja, now 51.

Today, his community – and other indigenous peoples across the Chaco, a tapestry of swamp, savanna and thorny forest across four countries that is South America’s largest ecosystem after the Amazon – are confronting a dramatic new change.

Filipinos count cost of climate crisis as typhoons get ever more destructive

The Philippines adds little to global emissions but faces some of its worst effects in extreme weather. Climate justice is needed

A few days before Christmas, Super-typhoon Rai – known locally as Odette – ravaged the Philippines. The morning after the onslaught, on my way back to Iloilo City from San Jose, Antique, I could see the ocean still boiling; houses blown away and great trees knocked down, making roads impassable. The sights were terrifying.

Lost lives continue to climb two weeks on. Vast numbers of buildings were destroyed – from houses to schools; food crops lost to flooding. At first, I did not know what to feel – anger, helplessness? Later, I knew what I wanted: climate justice.

Fury as EU moves ahead with plans to label gas and nuclear as ‘green’

Brussels faces backlash and charges of greenwashing after publishing draft proposals on New Year’s Eve

The European Commission is facing a furious backlash over plans to allow gas and nuclear to be labelled as “green” investments, as Germany’s economy minister led the charge against “greenwashing”.

The EU executive was accused of trying to bury the proposals by releasing long-delayed technical rules on its green investment guidebook to diplomats on New Year’s Eve, hours before a deadline expired.

‘We can transition to a better country’: a trans Colombian on diversity in ecology and society

Brigitte Baptiste has a high profile as a transgender Colombian woman and an ecologist – in a country where both are targeted

When Brigitte Baptiste walks on to the 10th floor of Bogotá’s Ean University at 9.45am in a plunging dress, knee-high cheetah-print boots and a silvery wig, the office comes to life. She examines some flowers sent by the Colombian radio station Caracol to thank her for taking part in a forum, her co-worker compliments her on her lipstick, and she settles in for a day of back-to-back meetings, followed by a private virtual conversation with the UN secretary general, António Guterres. Later that evening, she flies to Cartagena for a conference on natural gas.

The 58-year-old ecologist is one of Colombia’s foremost environmental experts, and one of its most visible transgender people, challenging scientific and social conventions alike. An ecology professor at the Jesuit-run Javeriana University for 20 years, she has written 15 books, countless newspaper columns, and won international prizes for her work. Most recently, she was appointed chancellor of Ean University, a business school, as part of its push for greater sustainability.

House of healing: the Honduran sanctuary for female rights defenders

In one of the world’s most dangerous regions for environmental and human rights activists, La Siguata offers a safe space for women suffering trauma as a result of their work

A milky-white and sky-blue stone hangs from a red string around Ethels Correa’s neck, and every so often she rubs it between her fingers.

“When I feel anger, I grab this stone and I begin to relax, because they taught me how to breathe, to relax the body and to relax the mind,” she says. “I carry it with me all the time.”

Apocalypse nowadays: the new wave of films about the end of the world

Armageddon once delivered thrills and megabucks spectacle. Now it’s the unnerving backdrop for satires and family drama

Which films kept you entertained over the holidays? Was it Silent Night, the sweary festive Britcom starring Keira Knightley? The courtroom drama Naked Singularity, with John Boyega as a crusading lawyer? Or did you watch Leonardo DiCaprio as a dorky astronomer in Don’t Look Up, a slapstick political satire? Whichever it was, I hope you poured yourself a large one, because none of those films are quite as light as they seem. All take place in the shadow of imminent Armageddon.

That’s right: the end of the world is nigh, and it’s no longer the preserve of megabudget disaster movies or bleak survivalist thrillers. These days the looming obliteration of our species can just as readily form the backdrop to some governmental mockery or a boozy country-house drama.

As I bum-shuffled my way down the scree at Avalanche Peak I wished I was back in the bush | Rose Lu

As my family were neither middle class nor white European I didn’t venture into the bush until I was an adult – I’ll never forget my first time

  • Guardian writers and readers describe their favourite place in New Zealand’s wilderness and why it’s special to them

Nothing beats the New Zealand bush. The writer Ashleigh Young once tweeted: “Sometimes NZ writers say ‘the forest’ instead of ‘the bush’ (and they definitely mean ‘the bush’) because they are nervous about saying ‘the bush’. Bring back the bush. If everyone does it, we will be fine.”

So here I am, proclaiming, “I love the bush!” Perhaps this is my opinion as an outdoor enthusiast and bisexual, but “bush” is the more accurate descriptor for the native flora of Aotearoa. Our bush is dense and scratchy, inured to the trample of boots. Our bush is thick and lush all year round, as few native plant species are deciduous. Our bush is not some wan forest: it is wild and overgrown, it does not encourage easy passage.

Colorado wildfire: up to 1,000 buildings destroyed as Biden declares disaster

At least seven reported injured while cause of the blaze remains under investigation

Up to 1,000 buildings may have been destroyed in the record wildfire that swept through a Colorado area abutting the Rocky Mountains, as Joe Biden declared the situation a disaster and experts warned that the climate crisis and suburban expansion contributed to the devastation.

After declaring that it was a miracle, based on the latest information, that no one was killed in the fire that roared with little notice through Boulder county on Thursday, officials said that more than 500 and as many as 1,000 homes and businesses may have been razed.

Sands of time are slipping away for England’s crumbling coasts amid climate crisis

Along the eastern shore, seaside attractions are being demolished and millions of homes are at risk as rising sea levels speed erosion

From a distance, the beach at Winterton-on-sea in Norfolk looks like the opening scene of Saving Private Ryan, with hundreds of grey bodies lying motionless across the sand. On closer inspection, it becomes clear they are not fallen soldiers but a huge colony of seals taken to the land for pupping season.

It’s an amazing annual sight that draws tourists and nature-lovers from across the country, but another process is taking place that is pushing people back – the growing threat of coastal erosion. Just along from where the armies of grey seals lay with their white pups, there used to stand the Dunes Cafe, a much-loved beach facility with a large and loyal clientele.

That’s a wrap: French plastic packaging ban for fruit and veg begins

Law bans sale of carrots, bananas and other items in plastic as environment groups urge other countries to follow

A law banning plastic packaging for large numbers of fruits and vegetables comes into force in France on New Year’s Day, to end what the government has called the “aberration” of overwrapped carrots, apples and bananas, as environmental campaigners and exasperated shoppers urge other countries to do the same.

Emmanuel Macron has called the ban on plastic packaging of fresh produce “a real revolution” and said France was taking the lead globally with its law to gradually phase out all single-use plastics by 2040.

‘Waste colonialism’: world grapples with west’s unwanted plastic

Germany and UK are big exporters of plastic, much of which lies rotting in ports in Turkey, Vietnam and other countries

One hundred and 41 containers filled with rotting plastic waste have been on a journey for more than a year. Scattered between Turkey, Greece and Vietnam, far from their origins in Germany, the containers’ voyage sheds light on the hidden global trade in plastic waste.

Arriving in Turkey in late 2020, shortly before a ban on mixed plastic waste imports came into force, the containers quickly became the centre of a battle between traders, a shipping line, multiple governments and environmental campaigners demanding their return.
