Welcome to Carbon Brief’s Cropped.
We handpick and explain the most important stories at the intersection of climate, land, food and nature over the past fortnight.
Key developments
Wildfires resurfaced
PANTANAL FIRES: Climate change made the wildfires that scorched the Pantanal wetlands earlier this summer 40% more intense, according to a new rapid attribution study covered by Carbon Brief. Around 2,500 fires occurred in Brazil’s Pantanal wetlands in June 2024. The World Weather Attribution service found that “the month was the hottest, driest and windiest year in the 45-year record”, creating conditions that were highly conducive to wildfires. Separately, Reuters reported on a new study that found that fires, logging and “other forms of human-caused degradation, along with natural disturbances to the Amazon ecosystem, are releasing more climate-warming CO2 than clear-cut deforestation”.
EXTENDED IMPACT: In North America, 90 large fires burned nearly 4.5m acres across the US during the first days of August, the New York Times reported. The “devastating wildfires” spread ash and smoke “over large swathes of the continent…destroyed homes and charred through thousands of acres of farms and forests”, the outlet added. Particularly dry, hot weather affected the western US and caused four wildfires across Colorado, leaving one person dead and forcing hundreds of people to evacuate, according to the Washington Post.
BEYOND AMERICAN CONTINENT: On the other side of the ocean, wildfires swept Athens, where thousands of residents were evacuated as fires crossed into suburbs and flames rose up to 25 metres, BBC News reported. According to the outlet, June and July were “the hottest on record” for the European country, while Greece’s civil protection minister has “warned that extremely dangerous weather would continue”. Meanwhile, Algeria’s north-eastern Kabylie region has experienced blazes since last Friday, Agence France-Presse reported. The newswire added that homes, olive groves, hen coops and beehives were engulfed by flames. Most of the wildfires are now under control, a civil defence official said.
Offsets up in smoke
UP IN SMOKE: The Park fire – one of the “largest wildfires in California’s history” and is still blazing – destroyed around 45,000 acres of trees enrolled in the state’s carbon-offsetting programme, the Financial Times reported. According to analysis by the not-for-profit research firm Carbon Plan, cited in the story, buyers of credits included oil refining, power and lumber companies. The story also pointed to an unsold “buffer pool” of credits meant to replace losses to “credited trees” from wildfires, drought or pests. California authorities told the FT that the buffer was “quite sound”. But Carbon Plan scientist Dr Grayson Badgley said that the pool needed updating to “reflect the realities of fire risk” and that the state “should stop approving carbon credit projects in risky wildfire regions”.
STOLEN CREDIT: Brazil’s environment minister, Marina Silva, warned international buyers of carbon credits to be “vigilant” after police uncovered “allegedly fraudulent emissions-offset schemes on stolen land in the Amazon”, the Financial Times wrote. Silva said the issue was a “serious problem” and “could damage the credibility [and] integrity of this mechanism”, the story added. Separately, Bloomberg reported that a key oversight body is set to review carbon offsets generated from forestry projects “in the coming months”, after it found methods to assess renewable energy credits to be “insufficiently rigorous”.
FOREST THINNING: Meanwhile, scientists writing in the Conversation cautioned against the Australian forest industry’s plans “to remove trees from native forests, potentially including national parks, and claim carbon credits in the process”. They pointed to Forestry Australia’s “problematic proposal” that “purports to reduce environmental impacts, but still produce wood products”. It does so through a method known as “adaptive harvesting”, which involves forest thinning, or practices such as delaying logging until trees are older. The group’s acting president, William Jackson, responded to the piece, saying that forest thinning would be “conducted for ecological reasons, cultural values or fire management or other reasons” and that he “disagrees with the view that thinning makes forests more fire prone”.

Joshua trees are flowering more frequently due to climate change
This week, Carbon Brief explores a new study, published in Ecology Letters, looking at the impacts of climate change on the Joshua tree, a type of yucca plant that is native to California and other parts of the south-western US.
Climate change is causing Joshua trees – the iconic plant that dots the landscape of the south-western US – to flower more frequently, a new study has found.
Despite the plant’s importance as a keystone species in the Mojave Desert and other parts of the south-west, many studies of climate impacts on Joshua trees lack nuance – in part due to the resources needed to collect field data.
Using a machine-learning model trained on crowdsourced images from the biodiversity platform iNaturalist, researchers were able to examine the impacts of climate change on the trees since 1900.
The lead author of the study told Carbon Brief that “there’s a lot of potential” to use the team’s newly developed methods to study the impacts of climate change on other flora.
Beyond binary
Much of the existing work looking at climate change impacts on Joshua trees is based on so-called “distribution models”, Prof Jeremy Yoder, an evolutionary biologist at California State University, Northridge, told Carbon Brief.
These models are based on identifying the climatic factors that are closely associated with the presence or absence of a particular species. Then, he explained, researchers can “take a future climate projection and ask where conditions will look like places where we know Joshua trees are today”.
In the new study, instead of simply looking at the distribution of the species, the researchers modelled the flowering of the trees – using specific weather data to draw connections between a flowering year and the climatic conditions leading up to it.
Using this model, they were then able to “hindcast” previous instances of Joshua tree flowering. They matched up their predicted flowering with historical botanical collections, field notes and even newspaper reports and found that they “line up pretty well”.
By taking the hindcast as a whole, the team could then explore how climate change has affected Joshua tree flowering over the past century and a quarter. Yoder told Carbon Brief:
“That’s concretely new information that we did not have about Joshua trees before.”
Flowering frequency
Overall, the researchers found a “slightly rising frequency” in the flowering of Joshua trees over the past 123 years. The flowering was most closely related to year-to-year variability in rainfall.
But increased flowering on its own might not necessarily be beneficial to the trees. “Flowering is just the first step in regenerating Joshua tree woodland,” Yoder said – meaning that more frequent blooms will not necessarily result in a growing population. While a flowering Joshua tree may produce thousands of seeds in a year, those seeds will result in just a few seedlings.
Then, it’s “an even smaller subset of seedlings that start to get to something closer to an established tree over a couple of years”, he said. And some of the conditions that seem to be influencing the flowering frequency – such as contrasts in year-to-year rainfall – are “probably not good for seedling survival”.
Beyond the scientific result, Yoder is excited by the potential for further applications of the hindcast modelling. He told Carbon Brief:
“Hopefully this is something that folks can use to start to get that richer view of what climate change is doing to natural populations.”
News and views
SKYROCKETING: Researchers have warned that the current H5N1 bird flu outbreak “could reach Australia this spring”, according to the Guardian. Australia has thus far remained bird-flu-free since the strain emerged in 2020. Although some researchers think the island’s virus risk “is low” due to the country being outside the “flyways of migratory ducks and geese, [which are] the main hosts of bird flu viruses over long distances”, others say “there is still a risk, and we need to be ready for it”. Mongabay also covered the bird flu transmission, highlighting that it is the “fastest-spreading, largest-ever outbreak” and has infected “hundreds of species pole-to-pole”. The outlet reported that the virus has spread to at least 485 bird species and 48 mammals and that “the risk to humans [is] rising”.
WHEAT STOCKS: Iraq’s wheat harvest surged more than 20% this year due to a combination of “extraordinary” rainfall and improved irrigation, Bloomberg reported. The outlet added that the harvest “marked a second year of self-sufficiency in the grain” for Iraq. Meanwhile, France is facing “one of the worst harvests in the last 40 years”, according to the French agriculture ministry, as reported by Politico. The country – which is the EU’s largest producer of soft wheat – “experienced a very wet planting season last year and not enough sun in the spring and early summer”. Farmers’ unions in France are seeking governmental assistance, the outlet said.
SEABED SHAKE-UP: Leticia Carvalho was elected the new head of the International Seabed Authority, Australia’s ABC News reported, where she “will be the first woman, first oceanographer and the first representative from Latin America to serve in this position”. Carvalho unseated the incumbent secretary-general, Michael Lodge, who has presided over the ISA since 2016. The New York Times noted that Lodge “has been a polarising figure at the seabed authority” and has faced accusations that he “was too closely aligned with the mining industry”. Prior to the election, Foreign Policy Magazine profiled Carvalho and her proposed approach to the ISA.
COCA PROBLEM: Colombia’s programme for substituting coca crops in favour of legal alternatives “is failing to achieve its goals due to design, implementation and security issues”, Mongabay reported. The outlet pointed out that coca leaf growers and pickers “haven’t received the agreed technical or financial support from the government”, resulting in lower incomes and forcing them to engage in other activities, such as illegal mining, to survive. The programme was created one year after the 2016 peace deal between Colombia’s government and the Revolutionary Armed Forces of Colombia (FARC), the outlet said. It added that a recent UN assessment of the programme found that coca production has actually increased 13% between December 2021 and December 2022.
NEW SEEDS ON THE BLOCK: On 9 August, Indian prime minister Narendra Modi launched 109 “high-yielding, climate-resilient” seed varieties at three experimental plots in New Delhi, Livemint reported. Among these was a rice variety “ideal for coastal saline areas” and a wheat variety “tolerant to terminal heat”, it added. Another Livemint long-read looked at the impact of climate change on tur dal – India’s second most consumed legume – finding that dal prices soared “by a staggering 60% between July 2022 and July 2024”. Meanwhile, an Economic Times analysis found that food inflation in India “has remained above 6% since July 2023, driven mostly by vegetables”. Overall inflation climbed to 5.1% in June this year with “most of the pressure…coming from rising food prices”, Bloomberg reported.

New science
Summer monsoon drying accelerates India’s groundwater depletion under climate change
Earth’s Future
New research found that changes in India’s summer monsoon, alongside warmer winters and increased demand, are driving “rapid depletion” of groundwater. Using satellite data, on-the-ground observations and a hydrological model, scientists observed that India’s groundwater declined substantially over 2002-21. They attributed the reduction in groundwater to “reduced groundwater recharge and enhanced pumping to meet irrigation demands” amid lower rainfall. They concluded: “Groundwater sustainability measures including reducing groundwater abstraction and enhancing the groundwater recharge during the summer monsoon seasons are needed to ensure future agricultural production.”
Highest ocean heat in four centuries places Great Barrier Reef in danger
Nature
Heat extremes in the sea containing the Great Barrier Reef over January-March in 2024, 2017 and 2020 were the “warmest in 400 years”, according to a new study. Using a multi-century reconstruction of sea surface temperature data on the Coral Sea on the Australian coast along with climate model analysis, the researchers highlighted the “existential threat” that human-caused climate change poses to the Great Barrier Reef ecosystem. Without “urgent intervention”, the researchers wrote that the reef risks “experiencing temperatures conducive to near-annual coral bleaching” in future. They noted: “In the absence of rapid, coordinated and ambitious global action to combat climate change, we will likely be witness to the demise of one of Earth’s great natural wonders.”
Global Change Biology
The 2022 marine heatwave in Fiordland, New Zealand – the “strongest and longest” to occur there – killed more than half of the marine sponges living there, a new study revealed. The researchers analysed the impacts of the marine heatwave – which had a maximum temperature of 4.4C above average and lasted for 259 days – on a particular photosynthetic sponge. They suggested that what killed marine sponges was not bleaching – which affected more than 90% of the sponges – but the high temperatures killing their tissues directly. The research concluded that the remaining sponges “had mostly recovered from earlier bleaching”, probably due to a microbial community shift as an “adaptive response”.

Cropped 14 August 2024: Worldwide wildfires; Offsets up in smoke; Joshua tree spotting
SYDNEY, Thursday 30 October 2026 — In response to reports that the Albanese government is set to introduce draft legislation this year that would seek to ban data centres in Australia’s suburbs, Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said:
“These reports are a testament to the growing community opposition to these completely inappropriate AI factories that have sprung up across our suburbs, and Big Tech corporations should take heed — the data centre build-out must not happen without the endorsement of the Australian people.
“But the government can’t simply ship this problem out to regional Australia without addressing the fundamental issues with this extractive new industry.
“We’re already seeing a trend of AI data centre proposals moving to the regions, in areas that are more water-scarce, more environmentally sensitive, and next to sources of fracked and coal seam gas to support their massive BYO gas-fired power plans — a pattern we’ve seen play out in the United States.
“From the Beetaloo Basin in the NT to the Western Downs in Qld, we’re seeing a wave of AI data centre proposals that would see new gas fast-tracked to support their massive energy demand, and threaten to completely derail Australia’s energy transition.
“Just as suburban Australians are asking, “what for?”, regional communities like Berry Springs and Dalby do not want dirty data centres setting up shop with absolutely no benefit to their communities. Greenpeace is calling for a moratorium on AI data centre developments until strict and enforceable safeguards are in place to protect our climate and our communities.”

AI data centre ban in suburbs would not address fundamental issues: Greenpeace
In the thick of the COP29 climate summit in Azerbaijan in 2024, the UN climate talks were rattled by what can only be described as a major PR disaster. The BBC, Reuters and The Guardian all carried headlines, attributed to leading climate policy experts, that the COPs were “no longer fit for purpose”.
The articles outlined a series of reforms called for in an open letter signed by 22 eminent scientists and politicians, including a former UN secretary-general and previous UN climate chief, with a further 150 lending their support. The headlines shook confidence in the COP process, just as governments were wrestling over a new climate finance goal.
The Club of Rome – which handled the media relations for the letter – hurried to say that its “constructive, supportive ideas” had been “misinterpreted”. Negotiators kept calm(ish) and carried on, in the end landing the finance goal after some high-stakes drama on the final day.

Africa wants adaptation finance on COP31 agenda, raising risk of a fight
The African Group wants dedicated space on tripling adaptation finance, the Green Climate Fund and trade, setting up a possible clash
To my surprise, when I went back this week to read the letter again, I could not find the offending line about the COPs not being fit for purpose. The Club of Rome has yet to respond to my query about its disappearance.
Whatever happened to the wording, that sentiment has been widely shared. COPs have ballooned in size while the importance of their outcomes seems to have diminished since the 2015 Paris Agreement (with the exception of the 2023 COP in Dubai where countries agreed to transition away from fossil fuels in energy systems).
The same on the surface
Two years on from those painful headlines in Baku, has anything changed for the better? You might be forgiven for thinking not. Official decisions are still made by consensus rather than the majority voting some have called for to stop blockers.
Tens of thousands of officials, activists and business execs still scurry around the halls to an ever-growing list of side events, roundtables and dialogues, while deals still come down to rows, all-nighters and jargon-filled texts adopted to rounds of applause.
But it would not be true to say that COPs have completely failed to respond to the very real need to translate the words of the Paris Agreement into action in the outside world.
Global warming is projected to be around 1.3C lower this century than it would have been if the world had not committed to tackle the climate crisis under that accord. Developing countries have a valued space at COPs in which their voices have equal weight in decision-making, unlike in many other international fora. And most importantly, perhaps, there has been a subtle shift, tipping the balance away from negotiating towards doing.
Brazil branded last year’s summit in Belém as the “COP of Implementation”, corralling the sprawling Action Agenda into six axes. This was a bid to impose some structure on the mushrooming efforts between governments, UN agencies, cities, businesses and civil society to set targets and spur faster results on their pet issues, from methane emissions to health and adaptation in conflict zones. COP30 alone saw the launch of 120 “plans to accelerate solutions”.
COP30 roadmaps off the cuff
Meanwhile, as the formal negotiations drew to a close, it was clear that consensus decision-making was evolving into something a little more improvised.
With only around half of all countries on board with the idea of a roadmap to transition away from fossil fuels, COP30 President André Corrêa do Lago announced his team would put one together over the coming year, along with another on how to meet a global goal to halt deforestation by 2030. Those roadmaps will be launched next week, presented and discussed at COP31, though it’s still unclear whether or how they’ll be incorporated into the formal negotiating agenda.
Some leading policy-makers don’t think that matters too much. Speaking to journalists before the Antalya summit, COP30 CEO Ana Toni and Dutch climate minister Stientje van Veldhoven said “coalitions of the willing” can move ahead without needing consensus from the COPs. This, they said, was evident this year at the first global conference on TAFF, co-chaired by van Veldhoven and attended by 60 countries.
“Consensus or no-consensus in the general COP doesn’t make a difference for the choices I have to make in my country to get my country to phase out fossil fuels,” said the Dutch minister. The Netherlands recently became one of the first to publish a national TAFF plan.
COP31 banks on flagship voluntary initiatives
This thinking has permeated the management and expected outcomes of this year’s COP too. Earlier this year, Türkiye, supported by international energy agencies, floated the idea of a voluntary goal to boost electrification to 35% of the world’s final energy consumption by 2035 – and this is now being touted as one of the main results to be expected from Antalya.
Türkiye is also championing a pledge on AI and climate, while co-host Australia is pushing to ease access to climate finance for least developed countries and small island states.
COP31 presidency announces AI pledge as UN climate chief says Big Tech ‘on thin ice’
None of these needs consensus. But with a political cover decision already in the works, as trailed by the COP presidents, they – and perhaps the fossil fuel roadmap – may find a home in the official text if language acceptable to most can be found, giving them them additional weight.
UNFCCC reform process in the shadows
Formal reform is underway too, if quietly. UN climate chief Simon Stiell is leading a review informed by ongoing consultations with a group of 15 well-respected climate policy experts, three of whom signed the open letter in 2024.
Among them is leading Swedish climate and sustainability scientist Johan Rockström who has strong ideas about how to make COPs function better, including a switch to majority voting. He told the same press briefing nothing stands in the way of this, because the rules of procedure for making decisions at COPs have never been formally agreed.
Still, to get away from the default setting of consensus would require agreement on a new system that may be impossible to achieve given the rise in bullying tactics by fossil fuel heavyweights.
