Stakes high as officials discuss summit’s key question of how much rich countries should pay for developing nations to cope with climate crisis and decarbonize their economies

In response to the latest text on climate finance, Laurie van der Burg, Oil Change International Global Public Finance Manager, said it was “a mixed bag with good, bad and ugly options.”

“Rich countries now have a last chance to step up to pay the climate debt they owe to the Global South and unlock a fair and funded fossil fuel phaseout, while barring dangerous distractions. Wealthy nations must support delivering the trillions urgently needed in public finance with the majority provided debt-free, which is currently on the table.”

Speaking at a press conference in Baku this morning, Hoekstra was asked for reaction to the lack of a clear figure on the climate finance - which currently just has an “X” for the target on the new collective quantified goal (NCQG).

“It is clearly unacceptable as it stands,” said Hoekstra, giving little else away.

On Qikiqtaruk, off Canada, researchers at the frontier of climate change are seeing its rich ecology slide into the sea as the melting permafrost leaves little behind

Last summer, the western Arctic was uncomfortably hot. Smoke from Canada’s wildfires hung thick in the air, and swarms of mosquitoes searched for exposed skin. It was a maddening combination that left researchers on Qikiqtaruk, an island off the north coast of the Yukon, desperate for relief.

And so on a late July afternoon, a team of Canadian scientists dived into the Beaufort Sea, bobbing and splashing in a sheltered bay for nearly two hours. Later, as they lay sprawled on a beach, huge chunks of the island they were studying slid into the ocean.

Peace Brigades International calling for new act to force companies with links to UK to do due diligence

Human rights defenders have faced brutal reprisals for standing up to extractive industries with links to UK companies or investors, according to a report calling for a law obliging firms to do human rights and environmental due diligence.

Peace Brigades International (PBI) UK says a corporate accountability law requiring businesses to do due diligence on their operations, investments and supply chains could have prevented past environmental devastation and attacks.

Exclusive: Trail would help region with few areas where people can walk in countryside, report says

A new trail along the east coast of England should be created, a Tory thinktank has said, because farmland is preventing those who live there from having access to nature.

A report from Onward has found that in most rural areas, people enjoy extensive rights-of-way networks. But across the east of England, there are many areas where people have barely anywhere they are allowed to walk in the countryside. This, the report says, is because of large areas of high-grade farmland in that area, but also because Lincolnshire has the largest backlog for recognition of historical but unrecorded rights of way, with more than 450 outstanding applications.

St Dominic, Tamar Valley: Leaves are filling up the tracks, glimmering in the murky shade, and our garden grows ever-more wild in the dry, mild weather

In gloomy November days, sunshine is at a premium. To the north, mist shrouds Kit Hill’s summit stack, but eastwards occasional streaks of pinkish light reflect on Dartmoor’s faded expanses of purple moor grass.

In the dullness, muted autumnal colours are strangely luminous, contrasting with the continuing growth of greenery. Black Angus yearlings lie content and replete on their lush green pasture; the pedigree herd of pale brown South Devon cattle also remain out of doors, alternated between fields, one distinguished by an ancient free-standing oak and hedgerow beeches. Rooks and jackdaws flock about the almost leafless beech, ignored by two imperturbable buzzards perched on telephone posts, overlooking the brown earth of a cultivated field sown with winter barley.

Ukraine's environmental protection minister, Svitlana Grynchuk, and the Palestinian chair for the environmental quality authority, Nisreen Tamimi, raised the alarm on the ecological impact of war in their countries and beyond. Grynchuk said Russia's 'unlawful reporting' of its carbon emissions on Ukrainian territory was undermining the integrity of the Paris agreement. Tamimi said the rebuilding effort in Gaza would release an estimated 30m tonnes of carbon dioxide

Communities on Paraná River fear privatisation of waterway operations will destroy way of life

River communities in Argentina fear that Javier Milei’s plans to privatise operations on a key shipping route could lead to environmental damage and destroy their way of life.

Since taking office almost a year ago, the self-styled “anarcho-capitalist” president has pledged to privatise a number of the state’s assets. The latest is the Paraguay-Paraná waterway – a shipping route of strategic importance for Argentina and its neighbours.

‘While it was dark, I climbed up and put remote control cameras in the tree. I’d never have got the shot if I’d been up there. An orangutan always knows you’re there’

I was following orangutans in Borneo with my wife, Cheryl Knott, a primatologist who has spent 30 years working in Gunung Palung national park, in the Indonesian part of Borneo. I am a biologist by background, and did my PhD research in rainforest ecology in Borneo, before I went into photography and film-making. I saw so much destruction in the rainforest back in the 90s, and it dawned on me that I could publish scientific articles that maybe 10 people would read – or an article in National Geographic that 10 million people would see.

I was getting increasingly serious about my photography while working on my PhD when I got funding from the National Geographic Society for field research. Through that connection, I was able to show them my pictures and eventually I published an article in the magazine about my work, which in turn meant I was able to get an assignment to document Cheryl’s orangutan PhD.

What is “The Real Cost of Net Zero” the political journalist Chris Uhlmann asked this week, after weeks of trailing his new documentary on Sky News Australia.

Uhlmann is no fan of Australia’s shift to renewables and, in a preview published in the Australian said politicians and governments “pushing ambitious renewables targets” were “breathtakingly, stunningly energy illiterate”.

Interviews and analysis of court documents show how the world’s most prestigious consulting firm quietly helps fuel the climate crisis

Two giant, mirrored walls are set to rise out of the sands of the Arabian desert. They will run parallel for more than 100 miles from the coast of the Red Sea through arid valleys and craggy mountains. Between them, a futuristic city which has no need for cars or roads will be powered completely by renewable energy.

This engineering marvel, its creators say, will usher in “a revolution in civilization”. It’s the jewel in the crown of a $500bn Saudi government project known as Neom, turning a vast scrubland into a techno-utopia and world-class tourist and sporting destination. Perhaps a harbinger for the end of oil, it will supposedly put the powerful petrostate at the forefront of the energy transition. For American consulting giant McKinsey & Company, its advising on this project appears to be making good on the firm’s green promises.

A recent strike narrowly missed slave trade archives in Barbados, and experts warn more and worse is to come as global heating intensifies storms

When the Barbados National Archives, home to one of the world’s most significant collections of documents from the transatlantic slave trade, reported in June that it had been struck by lightning, it received widespread sympathy and offers of support locally and internationally.

A section of the 60-year-old building, Block D, located on the grounds of the “Lazaretto” (the island’s former colony for people with leprosy), caught fire, and sustained serious damage. Official documents including hospital and school records were lost. “It was not just paper that was in the building, but documents that have stories about our families and ancestors,” says the chief archivist, Ingrid Thompson.

Researchers found no difference in the diversity of species in urban meadows compared with those in rural settings

Small patches of wildflowers sown in cities can be a good substitute for a natural meadow, according to a study which showed butterflies, bees and hoverflies like them just as much.

Councils are increasingly making space for wildflower meadows in cities in a bid to tackle insect decline, but their role in helping pollinating insects was unclear. Researchers working in the Polish city of Warsaw wanted to find out if these efforts were producing good results.

Unlocking secrets of how the algae survive could help extend growing seasons for crop plants at high latitudes

Plants left for too long in the dark usually turn sickly yellow and die, but scientists were astonished to discover tiny microalgae in the Arctic Ocean down to 50 metres deep can perform photosynthesis in near darkness.

The microalgae were at 88-degrees north and started photosynthesising in late March, only a few days after the long winter polar night came to an end at this latitude. The sun was barely poking up above the horizon and the sea was still covered in snow and ice, barely allowing any light to pass through. Typical light conditions outside on a clear day in Europe are more than 37,000-50,000 times the amount of light required by these Arctic microalgae.

All year, I have been looking forward to the People’s Blockade of the Newcastle coal port. I’ve been so excited to see the colourful array of kayaks and get to swim and paddle in the harbour with my friends to make our voices heard, and let the government know that we need to do everything we can right now to stop the climate crisis.

I know that Rising Tide has been working incredibly hard to make the blockade a fun and safe experience for everyone, but it feels like instead of listening to our concern about the climate crisis, the state government is doing everything they can to try to stop our “protestival” from going ahead.

Australia and Turkey are both lobbying to host Cop31, the world's annual United Nations climate change negotiations planned for 2026. The climate change minister, Chris Bowen, said Australia wants to co-host Cop31 'in partnership with our Pacific family'. Bowen also announced a $50m contribution to loss and damage caused by the climate crisis.

My brother called saying there was a storm. I was waiting, waiting, waiting. This is Elisa’s story

Location Saint-Martin-Vésubie, France

Disaster name Storm Alex, 2020

Elisa is a women’s clothing designer who runs her own label in Montreal, Canada. She was born and grew up in Nice, France, where much of her family remained, but was in Canada with her children and partner when Storm Alex gusted towards France and the mountain village where her mother lived. The storm was a powerful extratropical cyclone that caused extreme flooding around the Mediterranean, killing at least 15 people. Three months’ worth of rain – 50cm – fell on Saint-Martin-Vésubie in one day, 3 October 2020.

An update on our progress from the Guardian’s head of sustainability

• The Guardian environment pledge 2024
• Support urgent, independent climate journalism today

Five years ago the Guardian made a pledge that we would “play a part, both in our journalism and in our own organisation, to address the climate emergency” with our first annual environment pledge. That commitment reflected our long history of environment reporting and our view that individual companies had to take greater responsibility for their impact on the natural world. We wanted to demonstrate to readers that we were taking the action that our journalism showed was so necessary, and to be transparent about our progress. Today we publish the 2024 pledge.

Since then we have worked hard to measure and reduce our greenhouse gas emissions, to understand our impact on nature and to share our results openly with readers. In our latest sustainability report, published last month, we show that our emissions have fallen by 43% since 2020, putting us well on track to achieve our goal of a 67% cut by 2030.

Refurbishing an old building is subject to full VAT, but it isn’t if you build a polluting new one. The government’s priorities are all wrong

You can damn oil companies, abuse cars, insult nimbys, kill cows, befoul art galleries. But you must never, ever criticise the worst offender of all. The construction industry is sacred to both the left and the right. It may be the world’s greatest polluter, but it is not to be criticised. It is the elephant in the global-heating room.

It’s hard not to feel as though we have a blind spot when it comes to cement, steel and concrete. A year has now passed since the UN’s environment programme stated baldly that “the building and construction sector is by far the largest emitter of greenhouse gases”. The industry accounts for “a staggering 37% of global emissions”, more than any other single source. Yet it rarely gets the same attention as oil or car companies.

By relying on natural carbon sinks such as forests and peatlands to offset emissions, governments can appear closer to goals than they actually are

Relying on natural carbon sinks such as forests and oceans to offset continued fossil fuel emissions will not stop global heating, the scientists who developed net zero have warned.

Each year, the planet’s oceans, forests, soils and other natural carbon sinks absorb about half of all human emissions, forming part of government plans to limit global heating to below 2C under the Paris agreement.

Loved by tourists, elephants are, however, often loathed by farmers. Elephant conservation has been a been a success in Tsavo in Kenya, with their number increasing by about 6,000 in the mid-1990s to almost 15,000 in 2021. The human population has also grown, encroaching on grazing and migration routes for the herds, with resulting clashes becoming the No 1 cause of elephant deaths. But a long-running project by the charity Save the Elephants offered an unlikely solution: deterring some of nature’s biggest animals with some of its smallest: African honeybees

Questions raised over influence after 1,261 business and industry delegates registered for biodiversity summit in Colombia

Record numbers of business representatives and lobbyists had access to the UN’s latest biodiversity talks, analysis shows.

In total 1,261 business and industry delegates registered for Cop16 in Cali, Colombia, which ended in disarray and without significant progress on a number of key issues including nature funding, monitoring biodiversity loss and work on reducing environmentally harmful business subsidies.

Keir Starmer has confirmed that the UK has committed to an 81% cut to emissions by 2035. The prime minister also said the British government was due to launch the CIF Capital Markets Mechanism, a climate finance scheme, on the London Stock Exchange to help developing countries

Odd-looking creatures called ciona are naturally rich in protein and one company aims to farm and process them for the table

At a seaside restaurant near the docks in Fredrikstad, Norway, there’s a selection of delicious looking entrees sitting in front of me. There is a cheesy lasagne, a savoury Mexican casserole, and a spicy chilli con carne. Biting in to each one in turn, I savour the familiar taste of ground beef. Or is it?

The dishes come from Pronofa Asa, a Scandinavian company whose purpose is to make new and sustainable protein sources. In 2022, it acquired the Swedish research company Marine Taste and expanded on its work turning ciona – or “sea squirts” to you and me – into mincemeat. The dishes in Fredrikstad were prototypes, but Pronofa plans to have its mincemeat on supermarket shelves in Norway and Sweden before the end of the year, it says, and will aim to expand throughout Europe in the coming years.

Most recent fatality is 17th beluga to die since 2019 at Niagara Falls, Ontario, aquarium

Another beluga has died at Canada’s Marineland, as questions mount over the future of both the controversial theme park and one of the world’s largest populations of captive whales.

The most recent fatality – the fifth this year – is the 17th beluga to die at the Niagara Falls aquarium since 2019.

Newfoundland Memorial Univeristy team find white masses are likely material used to clean pipes in oil industry

When the chemist Chris Kozak finally got his hands on a sample of the mysterious blobs that recently washed up on the shores of Newfoundland’s beaches, Project Unknown Glob officially began.

Conservation groups are asking for the decision to allow Hvalur to hunt to be put on hold until after election

A coalition of conservation and animal welfare groups are urging Iceland’s president to step in and stop any plans the prime minister has to issue a whaling licence to Europe’s last whaler before the Icelandic election at the end of the month.

Earlier this year, the country granted a one-year licence to Hvalur to kill more than 100 fin whales this hunting season, despite hopes the practice may have been stopped after concerns about cruelty led to a temporary suspension in 2023.

Scientists use new technology to sequence the DNA of microscopic ocean creatures for the first time

Off the west coast of Greenland, a 17-metre (56ft) aluminium sailing boat creeps through a narrow, rocky fjord in the Arctic twilight. The research team onboard, still bleary-eyed from the rough nine-day passage across the Labrador Sea, lower nets to collect plankton. This is the first time anyone has sequenced the DNA of the tiny marine creatures that live here.

Watching the nets with palpable excitement is Prof Leonid Moroz, a neuroscientist at the University of Florida’s Whitney marine lab. “This is what the world looked like when life began,” he tells his friend, Peter Molnar, the expedition leader with whom he co-founded the Ocean Genome Atlas Project (Ogap).
