Mythic white sperm whale captured on film near Jamaica

Type of whale immortalised in Moby-Dick has only been spotted handful of times this century

It is the most mythic animal in the ocean: a white sperm whale, filmed on Monday by Leo van Toly, watching from a Dutch merchant ship off Jamaica. Moving gracefully, outrageously pale against the blue waters of the Caribbean, for any fans of Moby-Dick, Herman Melville’s book of 1851, this vision is a CGI animation come to life.

Sperm whales are generally grey, black or even brown in appearance. Hal Whitehead, an expert on the species, told the Guardian: “I don’t think I’ve ever seen a fully white sperm whale. I have seen ones with quite a lot of white on them, usually in patches on and near the belly.”

The rising cost of the climate crisis in flooded South Sudan – in pictures

Families facing severe hunger are wading through crocodile-infested waters in search of water lilies to eat. Susan Martinez and photographer Peter Caton return with Action Against Hunger to find that the dire situation they reported on in March has only worsened

Desperate families in flood-ravaged villages in South Sudan are spending hours searching for water lilies to eat after another summer of intense rainfall worsened an already dire situation.

People have no food and no land to cultivate after three years of floods. Fields are submerged in last year’s flood water and higher ground is overcrowded with hungry people, in what is quickly becoming a humanitarian crisis.

Nurdles: the worst toxic waste you’ve probably never heard of

Billions of these tiny plastic pellets are floating in the ocean, causing as much damage as oil spills, yet they are still not classified as hazardous

When the X-Press Pearl container ship caught fire and sank in the Indian Ocean in May, Sri Lanka was terrified that the vessel’s 350 tonnes of heavy fuel oil would spill into the ocean, causing an environmental disaster for the country’s pristine coral reefs and fishing industry.

Classified by the UN as Sri Lanka’s “worst maritime disaster”, the biggest impact was not caused by the heavy fuel oil. Nor was it the hazardous chemicals on board, which included nitric acid, caustic soda and methanol. The most “significant” harm, according to the UN, came from the spillage of 87 containers full of lentil-sized plastic pellets: nurdles.

Nobel-winning stock market theory used to help save coral reefs

Portfolio selection rules on evaluating risk used to pick 50 reefs as ‘arks’ best able to survive climate crisis and revive coral elsewhere

A Nobel prize-winning economic theory used by investors is showing early signs of helping save threatened coral reefs, scientists say.

Researchers at Australia’s University of Queensland used modern portfolio theory (MPT), a mathematical framework developed by the economist Harry Markowitz in the 1950s to help risk-averse investors maximise returns, to identify the 50 reefs or coral sanctuaries around the world that are most likely to survive the climate crisis and be able to repopulate other reefs, if other threats are absent.

Easy rider? We’ll miss the roar, but electric motorbikes can’t kill our road romance

For bikers, combustive power is one of the thrills of a long-haul trip. But flat batteries and charging points will just become part of exciting new journeys

A full tank of gas, a twist of the wrist, the roar of the exhaust as you speed towards the horizon … These are the visceral touchstones of the motorcycling experience, and all are a direct product of petrol-fuelled power, as is much of the biker’s lexicon: “open it up”, “give it some gas”, “go full throttle”. For a motorcycle rider, as opposed to the modern car driver, the journey is a full-body communication game, constantly applying judgment, skill and nerve to control the thousands of explosions that are happening between your thighs in order to transport yourself, upright and in one piece, to your destination.

Yet the days of the internal combustion engine are numbered. By 2050 the European Commission aims to have cut transport emissions by 90%, and electric vehicle technology is striding ahead for cars, trucks, buses and even aircraft. But where does this leave the motorcycle? Can this romantic form of transport and its subcultures survive the end of the petrol age?

Succession’s plot twist prompts surge of interest in leaving money in wills to Greenpeace

When Cousin Greg was disinherited by his grandfather in favour of the environmental group, inquiries about such legacies soared

In one bewildering and painful scene in the hit TV drama Succession, Cousin Greg sees his future of ease and wealth turn to dust. His grandfather, Ewan, announces he is giving away his entire fortune to Greenpeace, depriving Greg of his inheritance.

Now Greenpeace is hoping to benefit in real life as well as in the fictional world of the media conglomerate Waystar Royco. Thousands of people have looked into leaving money to the environmental group since the darkly comic storyline about Cousin Greg losing his inheritance and then threatening to sue the organisation was broadcast. More than 22,000 people have accessed online advice about making donations in their wills to Greenpeace. The group’s legacy webpage has also seen a tenfold surge in traffic since the episode was first broadcast earlier this month.

‘Taste this, it’s salty’: how rising seas are ruining the Gambia’s rice farmers

The farmers, mostly women, once grew enough but must now buy imported rice as the climate crisis edges them into poverty

In the sweltering heat of the late-morning west African sun, Aminata Jamba slashes at golden rice stalks with a sickle. “The rice is lovely,” she says, music playing in the background as her son, Sampa, silently harvests the grain. But even if the quality is high, the quantity is not.

While once Jamba could have expected to harvest enough rice to last the whole year, this year she reckons it will last three to four months. After that, she will have to look elsewhere for a way to feed her family and make enough money to live.

Great Barrier Reef: how a spectacular coral spawning event is helping to breed heat-tolerant corals

Scientists have carefully collected spawn bundles by moonlight in a bid to help save the reef

It’s nearing 10pm, and Dr Kate Quigley is still waiting. Using red lights to minimise disruption to the animals’ behaviour, she is inspecting corals.

Quigley, who studies reef restoration at the Australian Institute of Marine Science, is looking for “little red dots all over the surface”. A pimply appearance is a hallmark sign that a coral is about to spawn, releasing sperm and eggs in bundles resembling small bubbles.

‘I’m happy to lose £10m by quitting Facebook,’ says Lush boss

Losing 10m followers on sites such as Instagram is a price worth paying for co-founder of ethical beauty empire

Quitting social media is hard to do, even when it doesn’t cost you anything. So when Lush’s chief executive, Mark Constantine, shut its thousands of Facebook, Instagram, Snapchat and TikTok accounts on Friday, the biggest shopping day of the year, he knew dropping off millions of customers’ screens would damage his business.

Its Facebook and Instagram accounts alone had 10.6 million followers and the void will result in an estimated £10m hit to sales but Constantine, one of the business’s co-founders, said it had “no choice” after whistleblowers called attention to the negative impact social media sites such as Instagram are having on teenagers’ mental health.

‘Brands have been getting away with murder’: Stella McCartney and leading fashion figures on the fallout of Cop26

After Glasgow, there is a clamour for fashion companies to increase their commitment to sustainability and supply chain transparency – and for legislation to hold them to their promises

At the Cop26 conference, high-profile British brands including Stella McCartney, Burberry and Mulberry presented their visions for an ethical, sustainable industry. Now, there is an increasing demand for all fashion companies to make legally binding commitments to address the impact their supply chains have on the environment. While hundreds of companies – including Gucci-owner Kering, H&M and Inditex, which owns Zara – have signed up to the UN’s Fashion Industry Charter for Climate Action, which sets science-based targets in line with the Paris agreement, there is no obligation to take part, nor a legal mandate to hold brands to account.

Leading industry figures say that if fashion brands are to have any chance of having a meaningful impact on the climate crisis, legislation is needed.

Battery power: five innovations for cleaner, greener electric vehicles

EVs are seen as key in transition to low-carbon economy, but as their human and environmental costs become clearer, can new tech help?

While the journey to a low-carbon economy is well under way, the best route to get there remains up for debate. But, amid the slew of “pathways” and “roadmaps”, one broad consensus exists: “clean” technology will play a vital role.

Nowhere is this truer than for transport. To cut vehicle emissions, an alternative to the combustion engine is required.

Blowing the house down: life on the frontline of extreme weather in the Gambia

A storm took the roof off Binta Bah’s house before torrential rain destroyed her family’s belongings, as poverty combines with the climate crisis to wreak havoc on Africa’s smallest mainland country

The windstorm arrived in Jalambang late in the evening, when Binta Bah and her family were enjoying the evening cool outside. “But when we first heard the wind, the kids started to run and go in the house,” she says.

First they went in one room but the roof – a sheet of corrugated iron fixed only by a timbere pole – flew off. They ran into another but the roof soon went there too.

Sales of eco-friendly pet food soar as owners become aware of impact

Number of products in UK containing MSC-certified sustainable seafood has grown by 57% in last five years

Eco-friendly pet food is on the rise as dog and cat owners become more aware of the impact of their beloved pet’s diet.

New figures released exclusively to the Guardian show that the number of pet food products containing Marine Stewardship Council (MSC)-certified sustainable seafood has grown by 57% in the UK during the last five years, from 49 to 77. In the last year alone consumers bought more than 7m tins, pouches and packs of MSC-certified pet food.

‘It’s as if we’re in Mad Max’: warnings for Amazon as goldmining dredges occupy river

Hundreds of illegal goldmining dredges converge in search of metal as one activists describes it as a ‘free-for-all’

Environmentalists are demanding urgent action to halt an aquatic gold rush along one of the Amazon River’s largest tributaries, where hundreds of illegal goldmining dredges have converged in search of the precious metal.

The vast flotilla – so large one local website compared it to a floating neighbourhood – reportedly began forming on the Madeira River earlier this month after rumours that a large gold deposit had been found in the vicinity.

Fabrice Monteiro’s best photograph: a spirit emerges from a rubbish dump in Senegal

‘The model is holding a child’s doll, looking out over the wreckage. It represents the future generations we’re condemning to environmental catastrophe’

Outside Dakar, Senegal’s capital, is a rubbish dump with its own name: Mbeubeuss. The land on which it sits was once flat swampland. It began as a landfill site in 1968; today, it is a mountain of rubbish. It has accumulated so much plastic waste from the city that to reach it you have to drive on a road of compacted trash.

This is not the Africa I grew up in. As a child here in the 1970s and 80s, it was not like this. But when I returned in 2012, I was shocked at what I found. Here in Senegal, there was plastic waste everywhere – at roadsides, in trees, everywhere. The younger generation don’t know any different: it’s just part of their environment now. I decided I wanted to shoot a series to raise awareness of environmental issues in Senegal, in the hope that people would realise that things do not have to be this way. I wanted to connect environmental issues with the cultural interests of the population, and started researching animism – the belief that objects and the natural world are imbued with spirits.

India’s apple farmers count cost of climate crisis as snow decimates crops

Kashmiri farmers lose half their harvest to early snows for third year, with fears for future of the region’s orchards

The homegrown apple is in danger of becoming a rarity in India, as farmers have lost up to half their harvest this year, with predictions that the country’s main orchards could soon be all but wiped out.

Early snowfalls in Kashmir, where almost 80% of India’s apples are grown, have seen the region’s farmers lose half their crops in the third year of disastrous harvests.

Climate crisis pushes albatross ‘divorce’ rates higher – study

Researchers say warmer waters mean birds are travelling further for food and becoming more stressed, triggering relationship breakdowns

Albatrosses, some of the world’s most loyally monogamous creatures, are “divorcing” more often – and researchers say global heating may be to blame.

In a new Royal Society study, researchers say climate change and warming waters are pushing black-browed albatross break-up rates higher. Typically after choosing a partner, only 1-3% would separate in search of greener romantic pastures.

Frog back from the dead helps fight plans for mine in Ecuador

Campaigners say if copper mine gets go-ahead in cloud forest, the longnose harlequin, once thought to be extinct, will be threatened again

Reports of the longnose harlequin frog’s death appear to have been greatly exaggerated – or, at least, premature. The Mark Twain of the frog world is listed by the International Union for Conservation of Nature (IUCN) as extinct, which may come as a surprise to those alive and well in the cloud forests of Ecuador’s tropical Andes.

Known for its pointed snout, the longnose harlequin frog (Atelopus longirostris) is about to play a central role in a legal battle to stop a mining project in the Intag valley in Imbabura province, which campaigners say would be a disaster for the highly biodiverse cloud forests.

‘All my friends went home’: a fruit picker on life without EU workers

With fellow Europeans leaving the UK, and no British workers taking their place, Eleanor Popa’s job harvesting strawberries has gone from tough to tough and lonely. Will the farm survive another year?

Eleanor Popa used to sleep in a six-berth caravan on the site of Sharrington Strawberries, a 16-hectare (40-acre) strawberry farm in Melton Constable, Norfolk. Now, there are only four people in her caravan: everyone else has left to work in EU countries. “My friends,” she says, “they went home, or to work in Spain and Germany. A lot of them did not come back to work this year.”

Popa, who is from Bulgaria, has been a fruit picker for two years. “It’s hard work,” she says. “We have to get up early and pick. It’s 6am in the summer. Now we get up at 7.30am. And we work in tunnels. Sometimes it’s cold, sometimes it’s hot. Sometimes it’s windy. It can be boring.” Picking strawberries is skilled work. “It took me a month to learn how to pick the fruit,” she says.
