Key developments
Tree-planting under scrutiny
TREE BLACKOUT: Almost a third of the climate benefits derived from planting trees in order to remove more CO2 from the atmosphere could be offset by changes to atmospheric chemistry and the amount of sunlight reflected back into space, according to a new Science study which was widely covered by the world’s media. Increasing tree cover can alter the reflectiveness, or “albedo”, of the land, making it darker and more absorbent of heat. This albedo effect, combined with changes to atmospheric composition, is responsible for tree-planting having a smaller climate benefit than previously suggested, according to the paper. Writing in the Conversation, the researchers said that “tackling climate change by planting trees has an intuitive appeal”, but, in reality, “could affect the climate in complex ways”.
AFRICAN RISK: Elsewhere in Science, researchers published a policy commentary article arguing that the push for tree-planting across Africa could endanger biodiverse and carbon-rich grassland ecosystems. The researchers examined the likely impact of pledges made under the African Forest Landscape Restoration Initiative, which seeks to restore 100m hectares of degraded land – an area the size of Egypt – by 2030. The initiative is backed by the German government, the World Bank and the non-profit World Resources Institute, according to the Financial Times. The newspaper said that the researchers estimated that half of the land earmarked for regeneration by the project is in grassy savannahs or other non-woodland areas. The Guardian added that, according to the findings, “an area the size of France is threatened by forest restoration initiatives that are taking place in inappropriate landscapes”.
‘ERAS FORESTS’: A debate about the environmental impact of Taylor Swift’s Eras tour – the highest-grossing music tour in history, which will see the singer travel by private jet to perform in 151 locations across five continents from March 2023 to December 2024 – further highlighted the limits of tree-planting to counter emissions. For Forbes, two environmental scientists suggested that Swift could help to offset her private-jet emissions and set a good example by investing heavily in an “Eras forests” carbon-offsetting scheme to replant trees in each location that she has performed in. However, writing on LinkedIn, Richard Reiss, a founder of a climate change educational game, argued that offsetting all of the emissions associated with the Eras tour would require “increasingly unrealistic, or literally impossible, amounts of carbon capture”.
EU passes ‘landmark’ law for nature restoration
‘LANDMARK’ LAW: On Tuesday, the European parliament passed a “landmark” nature restoration law, aiming to “reverse the decline of Europe’s natural habitats” with an EU-wide target of restoring 20% of degraded land and sea areas by 2030, Deutsche Welle reported. The passage of the law occurred despite opposition from farming unions and the European People’s Party – the largest party in parliament. However, the EU council still needs to give the legislation final approval before it can enter into force. Deutsche Welle wrote: “While such a green light would normally be a formality, it is not guaranteed and some recent EU policies have faced blockages and delays because of domestic pushback.” Carbon Brief has just published a piece explaining the new law and its scientific foundation.
‘POLITICAL STORM’: Euronews noted that the margin of the bill’s passage – 329 votes in favour and 275 against, with 24 abstaining – was “a margin larger than initially expected”. Politico reported that the passage of the law “mark[ed] the end of a months-long campaign to kill the legislation” from right-wing groups. However, it added that the “final text was significantly weakened during negotiations”. The “weakened” legislation gives member states more flexibility on how they will implement its guidance, the outlet added. Euronews also reported that “the eruption in January of Europe-wide farmer protests reinvigorated the backlash against the Green Deal”, with the nature restoration law “once again thrust to the centre of the political storm”.
CHAOS IN THE CAPITAL: Meanwhile, farmer protests have continued across the bloc. Reuters reported that “about 900 tractors jammed parts” of Brussels and “riot police fired water cannon at protesters throwing bottles and eggs” while agricultural ministers were meeting in the Belgian capital this week. The Associated Press reported that protesters “spray[ed] Brussels police with liquid manure” in what the newswire described as a “fresh show of force”. It added: “The ministers were keen to show that they were listening, and a group of farmers’ representatives were allowed in for talks”. According to Politico, “the stench of manure, burning tires and teargas pervaded downtown Brussels on Monday” amidst “chaotic scenes”.
Chocolate ‘meltdown’
SHRINKING SWEETS: The price of chocolate surged to an all-time high of just over $6,500 per tonne on the New York and London stock exchanges this week, the trade publication Confectionery Production reported. Bloomberg columnist Javier Blas boldly claimed that “the meltdown in chocolate is coming”, with bars and boxes expected to shrink as prices reach unprecedented levels. According to Blas, four countries – Ivory Coast, Ghana, Cameroon and Nigeria – produce nearly 75% of the world’s cocoa. It is unusual for a major global commodity in that it is mostly grown by poor smallholder farmers, he said.
DWINDLING SUPPLIES: Prices have risen as fierce demand for cocoa has outstripped production by west African small producers, Blas said. Earlier on in February, BBC News reported that farmers have been experiencing poor harvests as a result of the El Niño weather phenomenon, which has been causing drier weather in Ghana and Ivory Coast. In December, Bloomberg reported that, before the dry weather, farmers in Ghana and Ivory Coast also faced a deluge of rainfall at a “crucial time for harvests”. It added: “Puddle-filled drives are bogging down transportation, and the soggy conditions allow diseases like black pod to run rampant, causing beans to rot on trees.”
CLIMATE INFLUENCE: West Africa has seen an increase in agricultural droughts because of climate change, according to the most recent assessment of the continent by the Intergovernmental Panel on Climate Change (IPCC). The report also found that human-caused climate change has already contributed to an increase in heavy rainfall and flooding across nearly all parts of Africa. Back in October, Dr Izidine Pinto, a climate scientist from Mozambique currently working at the Royal Netherlands Meteorological Institute, told Carbon Brief that the impacts of climate change had combined with El Niño to cause “very unusual” weather across the continent.
News and views
BRAZIL BEEF: Three of the world’s largest meatpacking companies sourced beef from ranches responsible for clearing an area of forest the size of Chicago (60,000 hectares) in the Cerrado savannah, a biodiversity hotspot in Brazil, alleged a new investigation by Global Witness covered by BBC News. The investigation said that deforestation linked to Brazil’s three biggest meatpackers – JBS, Marfrig and Minerva – was nearly five times greater in the Cerrado area of Mato Grosso than in the neighbouring Amazon rainforest, where the companies have legal agreements for monitoring their supplies. All three companies dispute Global Witness’s findings and said they are compliant with Brazilian law on deforestation and have their own individual supply chain agreements with Brazilian authorities.
ELEPHANT FATALITIES: Seven people in Malawi have been killed by elephants after the animals were moved as part of a conservation project overseen by two wildlife organisations, including one that was headed by Prince Harry, the Guardian reported. More than 250 elephants were moved from Liwonde national park in southern Malawi to the country’s second-largest protected area, Kasungu, in 2022, the outlet said. After the move, local communities warned that sections of electric fence designed to keep elephants and humans separate were incomplete, the newspaper added. The fatalities reportedly occurred when elephants came into contact with people outside of their protected area, it explained. In a statement seen by the Guardian, the International Fund for Animal Welfare, one of the groups involved in the project, apologised and pledged to finish installing the fence in 2024.
CALI CONFERENCE: Santiago de Cali, or Cali, will host the COP16 biodiversity summit in October, Colombian president Gustavo Petro announced last week. Cali is the country’s third-most-populous city and is the capital of the Colombian Pacific – the “most biodiverse region of Colombia”, Petro said in his remarks. According to a press release from the Colombian environment ministry, the Pacific region contains more than 200 protected areas and nearly 1,300 species of fauna. Colombia One, citing sources within the government, wrote: “The ethnic and cultural diversity of the region has played an important role in this decision.”
DRAX INVESTIGATION: The Panorama investigations team at BBC News has found evidence that the Drax biomass power station in North Yorkshire is still “burning wood from some of the world’s most precious forests”. It said: “Papers obtained by Panorama show Drax took timber from rare forests in Canada it had claimed were ‘no go areas’.” Drax told Panorama that its wood pellets are “sustainable and legally harvested”. Elsewhere, UK prime minister Rishi Sunak caused a stir by attending a farmers’ protest against the Welsh Labour government alongside a group that “has posted conspiracy theories about climate change and which campaigns against net-zero”, the Observer reported.
‘SATURATION POINT’: A 3,378-hectare Australian farm that had been “held up by the red meat sector as a vision of the future” has not been able to offset its own emissions since around 2017, according to a new report covered by the Guardian. The farm had initially planted hundreds of thousands of trees to sequester carbon. However, the outlet added: “[T]hose trees have now matured and passed peak sequestration…and the soil is so carbon rich it can’t sequester any additional CO2 from the atmosphere.” One of the farm’s owners, Mark Wootton, told the Guardian that their “regenerative approach to farming” is still beneficial, even if the farm is no longer carbon-neutral.
‘MEATY’ RICE: Scientists in South Korea have invented “meaty” rice, a hybrid food which they argue could provide an affordable and climate-friendly source of protein, BBC News reported. It explained: “The porous grains are packed with beef muscle and fat cells, grown in the lab. The rice was first coated in fish gelatine to help the beef cells latch on, and the grains were left in a petri dish to culture for up to 11 days.” The scientists, whose research was published in the journal Matter, told BBC News that the food may serve as “relief for famine, military ration or even space food” in the future.
Watch, read, listen
GRAN CHACO: Diálogo Chino reported on how livestock farmers in Argentina’s Gran Chaco are searching for more sustainable farming methods.
FAIR FOR FARMERS: A grassroots farmers’ advocacy non-profit in Florida was behind the “strongest set of workplace heat protections in the US”, the Washington Post wrote.
INDIGENOUS SPOTLIGHT: For the New York Times, law professor Robert Williams argued that “kicking native people off their land is a horrible way to save the planet”.
RAIN ON YOUR PARADE: Rain in the Arctic – increasingly common in a warmer world – is bringing a “cascade of troubling changes”, Yale Environment 360 wrote.
New science
Biodiversity footprints of 151 popular dishes from around the world
Plos One
A new study estimated the biodiversity footprints of 151 popular local dishes from around the world when globally and locally produced. It found that the dishes with the highest biodiversity impacts tend to be those made up of ingredients grown in biodiversity hotspots where agriculture pressures are high, such as fraldinha, a beef dish originating from Brazil, and chana masala, a chickpea curry popular in India. To come up with the results, the researchers considered popular dishes and a range of biodiversity indicators associated with the ingredients of each. The researchers added: “Regardless of assuming locally or globally produced, feedlot or pasture livestock production, vegan and vegetarian dishes presented lower biodiversity footprints than dishes containing meat.”
Rapid sea level rise causes loss of seagrass meadows
Communications Earth & Environment
“Unprecedented” and “rapid” sea level rise drove two common seagrass species out of nearly one-quarter of the sites monitored in the western Gulf of Mexico, according to new research. Scientists used data from long-term ecological monitoring sites, gulf-wide measurements of sea level rise and models of future sea level rise to determine how rising waters might affect seagrass meadows in the future. At one station, they found that two “ubiquitous” species “vanished altogether in just five years”. In modelling future risk, they found 14,000 square kilometres of seagrass habitat could be at risk of disappearing completely by 2050.
Arctic sea ice retreat fuels boreal forest advance
Science
New research found that changes in the Arctic sea ice extent influence the northward spread of the boreal forest, as well as the size of trees there. By combining data from field sites in northern Alaska with satellite data and previously published data from around the Arctic, researchers found a causal link between the advance of the forest and the retreat of the sea ice. They discovered that around the Arctic, “proportionally more tree lines have advanced” in regions of ongoing ice loss. The scientists concluded that “warming and reduced habitat for tundra organisms due to boreal forest advance will critically affect resource availability for Arctic-dwelling people”.

Cropped 28 February 2024: Chocolate crisis; Tree-planting scrutinised; EU restoration law
COP31 has finally kicked off in the sunny seaside resort of Antalya – at least for those lucky enough to have made it through the long queues snaking around the sprawling expo centre where the UN climate conference is taking place.
The joint COP presidents, Türkiye’s Murat Kurum and Australia’s Chris Bowen, have presented their priorities to fellow diplomats – including a new goal on electrification, the establishment of a just transition mechanism and better access to climate finance – before the negotiations begin in earnest.
Kurum announced that issues around the summit’s agenda had been resolved over the weekend. African countries had pushed for additional items on adaptation finance and trade, while Nepal wanted formal discussions on mountain issues in the wake of the devastating flooding disaster that struck the country.
Agreement was reached to drop the African request after late-night talks, with a view to continuing discussions on finance elsewhere such as in a dedicated work programme. Mountains and climate change will become a regular agenda item in the UN climate process with fresh dialogues planned on the topic.
COP31 Briefing: What to expect from the Antalya climate summit?
In his speech to the opening plenary, Australia’s environment minister Chris Bowen, who will preside over the negotiations in Antalya, outlined the COP co-presidents’ expectations for the cover decision that will offer a summary of the talks’ main achievements.
“There will be no surprises. This is not about duplicating negotiations. It will not be a lengthy political declaration, but a focused, practical, concrete response to the challenges and opportunities before us,” Bowen said.
It will be “a decision that reflects the urgency of the climate challenge and the enormous opportunities created by the global transition. One that gives confidence to governments, investors, businesses, communities that the world is moving faster and working together,” he added.
UN: El Niño unleashing heat from hottest oceans ever measured
As diplomats gather in Antalya, a new sobering update on the state of the Earth’s climate from the UN’s weather agency should focus minds.
The World Meteorological Organization (WMO) says the world’s oceans now hold more heat than ever measured. A rapidly strengthening El Niño is releasing some of that heat into the atmosphere, pushing temperatures higher on a planet already baked by human-caused climate change.
“El Niño and indeed the state of the global climate in 2026 gives new meaning to the phrase off the charts,” said the WMO’s Secretary General Celeste Saulo. “El Niño doesn’t add new heat to the planet. It releases heat from the ocean, which is the warmest ever measured. There is simply more heat available to release.”
The UN agency says 2026 is on track to be one of the four warmest years on record globally. That would make 2023 to 2026 the four hottest years in 177 years of observations. The global average temperature from January to September was 1.47°C above pre-industrial levels, just below 2024’s record of 1.55°C. The agency expects the final figure for the year to be higher as one of the strongest El Niños on record takes hold.
The current El Niño – a naturally occurring climate pattern – is expected to peak in December and continue until at least February 2027. As a result, the WMO expects global average temperatures to remain “exceptionally” high through late 2026 and into early 2027.

National climate plans now promise half the emission cuts expected by UN
The US exit from the Paris Agreement and weak new pledges leave 2035 emissions just 6% below 2019 levels, against 12% projected last year -
Tensions set to flare over trade at COP31 as China makes it a priority
After difficult talks in Belém last year, trade is likely to remain a sticking point at COP31 despite Brazil’s efforts to contain the issue to a series of dialogues
Bill Hare, CEO of the global science and policy institute Climate Analytics, said that while El Niño will command the headlines, “no one should be in any doubt that the bigger villain is man-made climate change”.
According to the WMO, El Niño typically adds around 0.1–0.2°C to annual global average temperatures. That is a fraction of the warming of more than 1.4°C recorded last year, which is primarily caused by greenhouse gas emissions mainly from burning fossil fuels.
UN boss António Guterres said a “supersized El Niño is colliding with a planet already superheated by manmade climate change”.
“Leaders must get serious by cutting emissions faster, accelerating a just transition from fossil fuels and delivering the finance and protection vulnerable countries need, “ he added.
At the COP31 opening ceremony, a Turkish promotional video struck a suitably apocalyptic note, implying that while nature and life on the planet will continue, humanity may not be a part of it unless countries choose to step up action to curb global warming.
IPCC chief urges governments to decide on report timeline
The chair of the world’s top climate science body has urged governments to take a long-delayed decision on when its next reports should be published so that they can steer climate action.
“Climate action without climate science is rather like a ship without a rudder,” said Jim Skea, the chair of the Intergovernmental Panel on Climate Change (IPCC).
He told the opening session of COP31 that the IPCC “faces operational challenges and reputational risks from the current impasse on the timeline for our three working group reports”.
Since 2024, governments have been unable to agree on whether the AR7 set of reports should be published before or after the next Global Stocktake (GST) of national climate plans in late 2028.
If the flagship reports are published before, they can feed into the agreed response to the second GST. At COP28, the first GST outcome included the landmark commitment to transition away from fossil fuels in energy systems.
Europe, small islands and the least developed countries, plus many Latin American and developed nations, want the IPCC to meet the deadline to inform the second GST.
But around a dozen developing countries plus Russia – led by India and Saudi Arabia – have argued that the reports should come later in order to allow for greater research input from the Global South.
After talks failed and were suspended last month, governments and IPCC scientists will try again to resolve the issue in virtual talks beginning on December 1.
Despite this disagreement among governments, Skea said the IPCC’s “scientific engine room is humming with activity” as scientists continue their work. But, as they are unpaid for their IPCC work, they are finding it increasingly difficult to find time for it alongside their “busy professional and personal lives”.
“In my early days in IPCC, we could plan our meetings literally years ahead. Now our authors don’t know what is expected of them in the early months of 2027,” he lamented.

FLIP OFF WOODSIDE TO SAVE SCOTT REEF: Greenpeace, Michael Caton, Thinkerbell mobilise Australia to challenge gas project at Scott Reef
6 November 2026
Greenpeace Australia Pacific has joined forces with Thinkerbell and iconic Australian actor Michael Caton on a major public movement and behaviour change initiative to save Scott Reef, calling on Australians to “flip off” gas corporation Woodside. The company plans to drill for gas at Australia’s largest oceanic reef, home to vulnerable green sea turtles, endangered pygmy blue whales, and thousands of marine species, off the coast of Western Australia.

At the heart of the collaboration is somebody who knows a thing or two about fighting off corporations to protect a home: Michael Caton. Set in a courtroom, Caton gives his voice to a voiceless inhabitant, a green sea turtle, and together they invite the public to show their support to save Scott Reef.
Designed to shift public behaviour and drive national debate, the movement asks the public to tag their MPs – applying direct political pressure on Environment Minister Murray Watt and Prime Minister Albanese Albanese to “flip off” Woodside’s dirty gas project, which would see up to 57 toxic wells drilled around Scott Reef off the coast of Western Australia.
Voiced by Michael Caton and set to a soundtrack provided by Radiohead, the narrative centres on our hero turtle defending her home from corporate overreach in a courtroom showdown. As the turtle defiantly flips her flippers at Woodside, Michael Caton calls on everyday Australians to take a stand and help save her home.
Michael Caton said: “I’m proud to lend my voice to Greenpeace to help save Scott Reef. The marine life out there can’t speak up, so we need to. Some things are too precious to risk.”
Glenn Walker, Head of Nature at Greenpeace Australia Pacific, added: “Woodside’s dirty gas project at Scott Reef, Australia’s largest oceanic reef, is an environmental disaster waiting to happen, threatening thousands of species, including the extremely vulnerable green sea turtles that nest there. By literally flipping off Woodside and Big Gas, Aussies are cutting through corporate spin and sending an unignorable message to Environment Minister Murray Watt and the Albanese government: save Scott Reef.”
Adam Ferrier, co-founder of Thinkerbell, said: “You can fight a corporation in the courtroom forever, but the real power to deliver lasting protection rests in parliament. Right now, our MPs hold an extraordinary opportunity to safeguard Scott Reef for generations to come. I’m proudly from WA, and I know how much the natural environment means to the people and economy of Western Australia. I’m also sure Woodside wants to do the right thing, and with enough public support and government action we’ll together save Scott Reef.
Paul Swann, Chief Creative Tinker at Thinkerbell notes: “When the stakes are this high, polite ads don’t work. You need an unignorable provocation that galvanises people and puts the pressure squarely where it belongs, on our leaders in Canberra. This isn’t just about protecting a reef; it’s about holding power to account.”
Greenpeace has been campaigning to stop Woodside’s dirty gas plans for years, increasing pressure on the Australian government to save Scott Reef from becoming an industrialised gas zone. From
