Unprecedented heat

‘RED ALERT’: The UN’s World Meteorological Organization (WMO) issued a “red alert” on climate change, after 2023 saw record heat, ice-melt and greenhouse gas emissions, the Associated Press reported. The WMO’s report confirmed that 2023 was the hottest year on record, with the average global temperature reaching 1.45C, noted the Guardian. The world is getting ever closer to temporarily breaching 1.5C, the ambition set under the Paris Agreement, the Independent said. 

IMPACTS REVEALED:  According to the WMO, extreme weather events are having an “alarming” impact on food insecurity, the Financial Times reported. The FT said there were 333 million people in 2023 who were “acutely food insecure”, compared to 149 million people before the Covid-19 pandemic. Elsewhere, Al Jazeera reported that “over 90% of ocean waters experienced heatwave conditions at least once” in 2023. 

SCIENTISTS STUNNED: Reacting to the report, Prof Jonathan Bamber, a glaciologist at the University of Bristol, told the i newspaper: “The pace of climate breakdown that we’re witnessing is faster than I think the vast majority of climate scientists were anticipating five or 10 years ago. Things are changing so rapidly that myself and quite a few of my colleagues do have concerns that some of our estimates could be on the conservative side.” It comes as leading climate scientist Dr Gavin Schmidt published a piece in Nature saying that researchers are finding 2023’s extremes “hard to explain” and that Earth could be entering “uncharted territory”.

Big Oil backtracks

TEXAS HOLD ‘EM: As Earth continues to face record-breaking extremes, executives from the world’s leading oil-and-gas companies gathered this week to “pour scorn” on efforts to move away from fossil fuels, reported the Guardian. According to the newspaper, Amin Nasser, the chief executive of state firm Saudi Aramco, told the industry’s annual Cera Week summit in Texas: “We should abandon the fantasy of phasing out oil and gas and instead invest in them adequately.” 

BUSINESS AS USUAL: Also reporting on the summit, Reuters noted that many oil-and-gas CEOs shared Nasser’s views, adding: “Shell’s Wael Sawan point[ed] to government bureaucracy in Europe as slowing needed development. Petrobras CEO Jean Paul Prates said caution should overrule haste. Exxon Mobil CEO Darren Woods also said regulations governing clean fuels have still not been resolved.” It came as the Guardian covered a new report from Global Witness suggesting that emissions connected to top oil and gas firms could cause 11.5 million additional heat deaths by 2100. 

Around the world 

  • CLIMATE MINISTERIAL: At a climate ministerial in Copenhagen, a “troika” made up of the United Arab Emirates, Azerbaijan and Brazil – the hosts of COP28, COP29 and COP30, respectively – urged countries to update their international emissions pledges by 2025, the Hindustan Times reported.
  • SCHOOL CLOSURES: South Sudan has closed all its schools for an expected two weeks as temperatures are forecast to reach 45C, BBC News reported. It comes as Carbon Brief covered a new attribution analysis finding climate change made recent heat in west Africa 10 times more likely.
  • US TRANSPORT: The Biden administration announced new rules to tackle pollution from the nation’s cars and light trucks, “imposing tailpipe emission limits so stringent they will compel automakers to rapidly boost sales of battery-electric and plug-in hybrid models”, Bloomberg reported. 
  • UK COURTS: The UK Court of Appeal has ruled that climate activists prosecuted in England and Wales for criminal damage can no longer use the “consent defence” – that they believe the property owner would have given their consent to the action if they understood the reason for the protest – the Financial Times reported. 
  • GREEN STEEL: A new report found that China is “falling short” in decarbonising its steel sector, due to “slowing demand, low recycling rates and lingering overcapacity concerns” impeding the transition to lower-emission production, said Reuters
  • BRAZIL HEATWAVE: Following a record “heat index” (which factors in the impact of humidity) of up to 62C in the Brazilian capital Rio de Janeiro last weekend, O Globo reported that heatwaves may become more frequent in the country.

The number of residents in India’s southern tech capital of Bengaluru who are running out of groundwater following an “unusually hot” February and March, the Associated Press reported. 


Latest climate research

  • Over the past 60 years, livestock grazing has reduced soil carbon stocks by 46bn tonnes of carbon at a depth of one metre, a study in Nature Climate Change found. 
  • Research in Nature Cities found that only 43% of 793 cities studied have implemented green recovery plans in response to the Covid-19 pandemic.  
  • A study in Climatic Change gathered the opinions of 20 policymakers and practitioners from different countries about the readability of figures drafted for the latest Intergovernmental Panel on Climate Change (IPCC) report on how to tackle climate change. It recommended ways that the figures could be improved, based on the feedback.

Replacing a gas boiler in the UK with a new heat pump would cut emissions by 77-86%

New Carbon Brief analysis debunked 18 of the most common and persistent myths about heat pumps. Heat pumps can significantly cut greenhouse gas emissions (see chart above) and are the “central technology in the global transition to secure and sustainable heating”, according to the International Energy Agency. Yet, in major economies such as the UK and Germany, heat pumps are the subject of hostile and misleading reporting across many mainstream media outlets, according to Carbon Brief’s new factcheck.

Rare-earth mining in Myanmar

This week, Carbon Brief interviews an expert about how rare-earth mining in Myanmar has increased since the country’s military coup in 2021, its impacts on local communities and the environment, plus how it can be better monitored and controlled.

Vicky Bowman for DeBriefed

Myanmar is rich in natural resources. It is home to a wealth of gemstones, energy sources, such as coal and uranium, as well as vast amounts of rare earths.

Dysprosium and terbium are two rare earths that are heavily mined in Myanmar. They are used in a range of everyday technologies, such as light bulbs, but are increasingly being used for renewable energy, including for electric vehicles and wind turbines.

As countries race to achieve their climate targets, demand for these rare earths is substantially increasing. The Irrawaddy reported that Myanmar exported more than 140,000 tonnes of rare-earth deposits to China between May 2017 and October 2021, valued at more than $1bn. 

However, much of Myanmar’s mining industry is illicit and controlled by armed groups. Illegal mining has grown since the country’s military coup in 2021, particularly along the Chinese border in Kachin State.

China, the world’s biggest low-carbon technology producer and the largest processor of rare earths, is now increasingly outsourcing its mining activities into neighbouring Myanmar amid growing national concerns over the highly polluting process.

Below, Carbon Brief speaks to Vicky Bowman (pictured above), director of the not-for-profit Myanmar Centre for Responsible Business, about escalating issues with rare-earth mining in the country. The interview has been edited for clarity and length.

Carbon Brief: Please can you give an overview of rare-earth mining in Myanmar and how it has developed since the military coup in 2021?

Vicky Bowman: Rare-earth mining has been taking place in Kachin state, north-eastern Myanmar, on China’s border for around a decade, mainly by Chinese miners in areas under the control of the pro-military Kachin militias. Chinese companies started to source more from Kachin state because of a clampdown on rare-earth mining in Yunnan due to environmental pollution.

Satellite footage commissioned by Global Witness showed that rare-earth mining has significantly expanded since the coup. It also takes place to a lesser extent in areas controlled by the Kachin Independence Organisation (KIO), which is opposed to the Myanmar military. The KIO planned to expand rare-earth mining to raise funds for their armed struggle, but they faced significant local backlash and dropped the expansion plans in 2023. 

CB: What impacts is rare-earth mining having on people, particularly Indigenous peoples, and the environment in Myanmar?

VB: Indigenous peoples in the areas where rare-earth mining is taking place in Kachin state, mostly Kachin ethnic minority, rely on agriculture and forests for their livelihood and culture. These areas are also rich in biodiversity. The leaching process for extracting rare-earth ores requires leaching it from the soil using ammonia and other chemicals. These chemicals enter the environment and poison the streams and fields, killing trees, cattle and local nature and making local people sick.

CB: What needs to happen to better monitor and control the impacts of rare-earth mining in Myanmar?

VB: The vast majority of mining in Myanmar nowadays is unplanned, unregulated and unlicensed. The national Mining Law is not fit for purpose. It fails to align with other laws, such as those concerning investment, environmental protection and land use. There are few, if any, officials in any of the ministries who understand how to regulate mining. Corruption is rife. If and when Myanmar’s political crisis is resolved, the policy and legal framework for mining needs to be completely overhauled into a federal system, which can ensure effective land-use planning and environmental protection, and transparent tax revenues for central and sub-national governments and local communities.

Indeed, creating an effective framework for responsible mining is central to resolving conflicts between local people and the central government, and should be a priority for anyone working on peace.

New Zealand moves to protect business with law curtailing climate litigation

Published

on

New Zealand’s parliament has adopted a controversial new law blocking a whole avenue of climate litigation and shutting down its most advanced corporate lawsuit, which has been blamed by the government for shaking business confidence and investment.

The Climate Change Response (Tort Liability) Amendment Bill, expected to take effect in the coming days after it is formally signed by the Governor-General, prevents all current and future civil claims for climate loss or harm under tort law.

Justice minister Paul Goldsmith said last week that the aim was to give businesses “certainty around their climate change obligations”, noting it would not alter the government’s responsibilities under the Climate Change Response Act 2002 nor business obligations under the Emissions Trading Scheme.

“Our response to climate change is best managed by the Government at a national level and not through piece-meal litigation in the courts,” he added in a statement.

Such litigation, he said, “risks developing a new regime that contradicts the framework Parliament has already enacted” to tackle climate change.

    Goldsmith singled out a key domestic climate lawsuit brought by Northland iwi leader and activist Mike Smith against six big companies: dairy firms Fonterra and Dairy Holdings, energy firms Genesis Energy and Z Energy, New Zealand Steel and coal mining firm BT Mining. A seventh original defendant, Channel Infrastructure, was dropped after it permanently decommissioned its Marsden Point oil refinery.

    Smith argued that these companies had caused him harm under public nuisance and negligence law, as well as a third breach of a duty to cease contributing to climate change that has yet to be tested domestically. He did not seek financial compensation, instead asking for the companies to immediately stop emitting or contributing to net greenhouse gas emissions.

    In one of the most advanced corporate climate accountability lawsuits in the world, a trial had been scheduled for April 2027 after the Supreme Court unanimously allowed the case to continue.

    Corporate lobbying in the shadows

    Smith described the passing of the bill as “deeply concerning”, particularly as it coincided with the Supreme Court hearing another of his climate lawsuits. In that case, Smith v Attorney-General, he argues that the government’s response to climate change and its impacts on Māori communities in particular breaches rights to life and culture.

    “That timing raises profound questions about the separation of powers and the rule of law,” said Smith. “Whatever one’s view of the merits of these cases, it is deeply troubling when parliament intervenes to remove a legal pathway while the courts are actively considering fundamental questions about climate responsibility, rights and the crown’s obligations.”

    The bill – which says that no person (including the government) can be found liable in tort for emissions-related climate change effects – followed major lobbying efforts by the companies defending themselves in Smith’s lawsuit. They outlined a proposed legal amendment in a briefing note to the government in 2024.

    The centre-right government has been fiercely criticised over its lack of transparency in relation to this lobbying activity. The national ombudsman recently found that the Prime Minister’s Office effectively withheld information requested by the Environmental Law Initiative about meetings, discussions and conversations regarding Smith’s case.

    Green groups fail to stop bill

    The bill sparked huge concern among environmental campaigners in New Zealand and elsewhere. Greenpeace Aotearoa called it a “shocking abuse of executive power” and the vast majority of submissions to a parliamentary inquiry said it should be rejected.

    But in the end, it was adopted with little resistance, moving relatively smoothly through parliament, passing its third reading by 67 votes to 53. Sam Bookman, climate law lecturer at Melbourne Law School, told Climate Home News he was not surprised by this, given that the coalition government has a secure majority.

    A complaint has been made to the UN special rapporteur on climate change and human rights by Smith, the National Iwi Chairs Forum Pou Tikanga and youth coalition Climate Clinic Aotearoa over what they see as the government’s heavy-handed approach. Smith is also challenging the new law in yet another lawsuit.

    “Pathetic”: New Zealand plans to barely cut emissions between 2030 and 2035

    Bookman thinks it “very unlikely” that such a challenge will succeed, noting that New Zealand’s constitution is firmly anchored in parliamentary sovereignty.

    But the expert in climate law does not see the bill as the end of legal action in the country, noting that New Zealand has a “sophisticated climate litigation landscape with a growing number of specialist and experienced lawyers and NGOs”.

    The country is also approaching its next general election in November, and some opposition parties have pledged to restore access to the courts if elected.

    Amanda Larsson, global project lead on agriculture for Greenpeace International, said: “This law deserves to be tested, and I strongly encourage the international climate litigation community to unite and help defend New Zealanders’ fundamental right to hold polluters accountable before this becomes a global blueprint.”

    Copycat legislation on the rise

    New Zealand’s move is part of a small but growing legislative effort to shut down climate litigation around the world.

    In the US, Republican politicians introduced legislation in the House and Senate in April that would shield fossil fuel firms from climate liability lawsuits. Similar laws have already been passed at state level in Tennessee, Utah, Iowa and Louisiana.

    The German state of Bavaria has put forward a similar proposal to the Federal Council, aiming to block private climate claims as well as the recognition and enforcement of foreign judgments imposing such liability. There are also proposals to limit available remedies and actions in the Netherlands and Belgium.

    UN General Assembly backs “climate obligations” set by world’s top court

    Bookman said he expects more efforts to counter climate damages litigation and advised plaintiffs to think about how to respond, including drawing on broader support in opposing them.

    “Even though it’s very hard for plaintiffs to win these types of cases, companies are very eager to avoid the expense, embarrassment and political accountability that come even with unsuccessful lawsuits,” he said.

    Indonesia’s nickel production cuts are not enough to create a sustainable industry 

    Published

    on

    Bhima Yudhistira Adhinegara is the Executive Director of the Center of Economic and Law Studies (CELIOS), an Indonesia-based economic think tank. Muhammad Zulfikar Rakhmat is the Director of the China-Indonesia desk at CELIOS. 

    Indonesia produces around 60% of the world’s nickel, a metal used to manufacture batteries for electric vehicles (EVs) – more than any other country in the world. But in 2026, the government sharply reduced how much of its nickel can be extracted from the ground.

    Production quotas were reduced by around 40% this year compared to 2025. Weda Bay, the largest nickel mine on Earth, had its allowance cut by more than 70% and exhausted its full-year quota by the end of May, halting mining entirely; it cannot resume large-scale extraction until next year unless regulators grant an extension.

    The policy has sparked a vivid debate in Indonesian policy circles: how can the country shift its strategy from a decade of mining vast quantities of cheap nickel to producing a high-value and low-carbon material that the rest of the world wants for EV batteries.

    The cuts aren’t a silver bullet to clean up Indonesia’s nickel industry, whose smelters are powered by coal – the most polluting fossil fuels. But alongside stricter enforcement of environmental rules, it is one side of efforts to produce more sustainable nickel for a premium.

    Restricting Indonesia’s nickel output

    Production quotas were introduced to stop the collapse of nickel prices because of oversupply in the market. Prices had fallen more than 40% in 2023 alone and kept sliding as Indonesian supply kept growing, hitting a four-year low of around $13,900 a ton in late 2025.

    Critics called the recent tightening of production quotas proof that Indonesia’s nickel strategy has failed, arguing that the industry shouldn’t need to throttle its own output to survive. But when assessed against what the policy was supposed to do – push up nickel prices – it has worked. Prices jumped to $20,000 a ton in May, the highest since 2024.

      Chinese industry groups representing companies that have invested billions to mine and refine the country’s nickel were furious, warning Indonesia’s president Prabowo Subianto that the cuts put $50 billion worth of investment at risk. But much of that Chinese capital is sunk into smelters and processing plants built specifically to run on Indonesian ore, and cannot simply be moved elsewhere. That gives Jakarta more room to hold its ground than the warning suggests.

      Stronger environmental enforcement

      Since the start of the year, Indonesia’s forestry task force has seized more than four million hectares of land from mines and plantations operating illegally in protected forests, collecting over two trillion rupiah ($113 million) in fines.

      This included 148 hectares seized from Weda Bay for lacking a forestry permit. The share of nickel produced from illegal small-scale mining also fell from about a quarter in 2022 to roughly 10% by 2024.

      The crackdown responds to serious environmental damages in the nickel industry. On Obi Island, a waste pond collapsed after heavy rain in June 2025, flooding three villages and killing a resident. Internal company tests found chromium-6 – a carcinogen – in the water, in quantities far above the legal limit. The footprint of another mine near Raja Ampat, which is home to some of the world’s richest coral reefs, grew 60-fold in just eight years.

      The market is responding to early cleanup efforts. Low-carbon nickel now sells for a real premium, roughly $18,800 to $19,300 a ton compared with $17,900 to $18,300 otherwise, as carmakers seek to source cleaner materials to comply with the European Union’s new emissions rules for imports.

      In turn, this is incentivising the industry to do more to green its operations. Vale Indonesia’s smelter in South Sulawesi now runs almost entirely on hydropower, for example.

      None of this addresses coal use, however. Major Indonesian nickel producers still emitted an estimated 15 million metric tons of greenhouse gases in 2023. Indonesia may be cracking down on illegal mining and rewarding cleaner producers but it is still running its mines on the dirtiest fuel available.

      Unequal benefits

      For Indonesia to truly benefit from producing cleaner and high-value nickel, it needs to reap the economic benefits too. Although the industry has boosted the country’s economic growth, the reality on the ground tells a different story.

      Konawe in Southeast Sulawesi is home to a major smelting complex. Growth in the district jumped from 6% to 22% between 2015 and 2023, driven almost entirely by the nickel industry, according to a study by the Lowy Institute study. At the same time, poverty levels increased slightly and unemployment remained unchanged.

        In Halmahera, another epicentre of the nickel industry, spending by the poorest fifth grew just 5% between 2019 and 2022, compared with 28% for the wealthiest fifth, according to a separate study.

        Part of the reason for this inequality is the system for transferring mining royalties to district authorities where the mines are located. In theory, they are entitled to the largest share. But in practice, payments are delayed, companies routinely dispute what they owe and royalties are pooled and distributed across a larger area.

        The Natural Resource Governance Institute has found that decentralisation handed local governments power to approve new mines faster than they could build their capacity to manage them. Higher output raises national income on paper, but local governments remain constrained by fiscal rules and infrastructure costs that scale with mining.

        None of this makes the 2026 quota cuts a mistake. Indonesia has every right to defend its pricing power over a resource it controls. But limiting extraction isn’t going to fix underlying issues around environmental enforcement and revenue-sharing. That requires rules that are consistently enforced, royalties that reach communities living by the mines, and a plan to wean smelters off coal.

        Risk of “catastrophic” oil spill reaching Kimberley coast found in Woodside’s Scott Reef gas drilling plans

        Published

        on

        SYDNEY, Monday 24 August 2026 – New analysis of Woodside modelling released by Greenpeace Australia Pacific and Environs Kimberley has revealed the oil and gas corporation’s plans to drill at Scott Reef could cause an oil spill up to 30 times bigger than the 2009 Montara disaster, impacting the Kimberley coastline and reaching as far as Indonesia.

        The new analysis details the “catastrophic” oil spill risk put to environmental regulators for approval by Woodside in its Browse to North West Shelf Project (Browse) plans, the worst-case scenario being a blowout directly below Scott Reef, polluting whale migratory pathways and covering isolated turtle nesting ground with oil condensate.

        An FOI application (F348) revealed the federal environment department (DCCEEW) asked offshore oil and gas regulator NOPSEMA to look into the oil spill risk in 2025. NOPSEMA’s response to the application refused access to its report, and one document shows DCCEEW sought further advice this year.

        Greenpeace and Environs Kimberley are calling on the Federal Government to publicly release the NOPSEMA report given the risk of an uncontrolled release of oil condensate from directly below Scott Reef.

        Hannah Schuch, Senior Campaigner at Greenpeace Australia Pacific, said: “Woodside is aware that drilling at Scott Reef risks a massive oil spill that would have severe, far-reaching consequences. It appears environmental regulators are aware too.

        “The state and federal governments need to take this risk from Woodside’s drilling plans seriously, as they could end up allowing the worst oil spill in Australian history.

        “The pygmy blue whales that migrate up and down the WA coast with their newborns each year could be swimming and feeding in toxic, oil-slicked water. Woodside’s proposal to drill at Scott Reef is an environmental disaster waiting to happen, and the WA and federal governments have one surefire way to prevent catastrophe — reject Browse.”

        Martin Prichard, Executive Director at Environs Kimberley, said: “A catastrophic oil spill by Woodside would be disastrous not just for marine life in the area but also for the Kimberley’s $500 million tourism industry.

        “The state and federal governments will see five marine parks on the Kimberley coast included in the risk area of a catastrophic Woodside oil spill.

        “The Montara oil spill was disastrous for West Timor with the toxic oil destroying seaweed farmers’ livelihoods. The Kimberley dodged a bullet with Montara, we were lucky the spill didn’t head our way. Myself and a crew flew over the Montara oil spill and followed it as far as we could. It was like a scene from a disaster movie.”

        After the WA Environmental Protection Authority deemed Browse “unacceptable” due, in part, to oil spill risk, Woodside submitted a mitigation plan based on technology that has never been used “in anger”, a weakness stated in an independent expert review of the plan.

        Professor Richard Steiner, independent oil spill expert, said: “A large offshore spill is impossible to effectively contain or recover. Historically, only 2-6% of total spill volume is recovered and the ecological injury from the release of toxic hydrocarbons in the sea can be severe, extensive, and long-term.

        “Here in Alaska, government research concludes that several marine populations injured by the 1989 Exxon Valdez oil spill, including whales, fish, and seabirds, are still not recovering today, 37 years later. We should expect similar long-term ecological impacts in Western Australia if there were to be a major oil spill. The only sure way to avoid the risk of a catastrophic marine oil spill is to not develop oil and gas projects in marine environments.”
