This week

Long hot winter

‘WORLD’S WARMEST’: Record heat has affected “everywhere from northern Siberia and central and north-west America to parts of South America, Africa and Australia” this winter, reported the Financial Times. BBC News reported that last month was the world’s warmest February “in modern times”, the ninth month in a row to be the hottest on record since June 2023. This puts the world temporarily above the 1.5C threshold, noted the Guardian.

‘WEIRD’ WINTER HEAT: The New York Times reported that the “fingerprints of climate change” were detectable on the “weird” winter heat, including in Iran’s capital city Tehran, which was 4.2C warmer than average during the winter months. Morocco experienced the hottest January since measurements began, the country’s meteorological department told Agence France-Presse, at 3.8C above normal. 

SMOKEHOUSE SCAR: Record winter heat continued to fan the flames of the “largest wildfire on record” in Texas, reported Axios. It added the blazes had left “a burn scar so large it is clearly visible from space”. Known as the Smokehouse Creek fire, it has burned more than 1.2m acres and “killed two people and thousands of cattle”, reported BBC Future. The publication explained that the fire has a “complex link” with climate change.

China’s pivotal ‘two sessions’ meeting

WHAT, WHEN, WHERE: China’s “two sessions” meeting, which sees the annual parliamentary gathering of the National People’s Congress and the Chinese People’s Political Consultative Conference, is currently underway in Beijing, Carbon Brief’s China Briefing newsletter reported. Its centrepiece is the “government work report”, a speech traditionally delivered by the premier that outlines priorities for the year ahead.

CLIMATE TARGETS: One of the few quantitative climate targets China set in the report is to reduce energy consumption per unit of GDP by 2.5% over the coming year, a goal that Bloomberg described as “modest”. The target was lower than analysts’ expectations of 4%, the outlet added.

FOSSIL FUELS REMAIN: The work report also restated a commitment to boosting fossil fuels in the name of “energy security”, Reuters reported. The newswire noted that China also aims to step up exploration of “strategic minerals”.  

Around the world

  • SURPRISE SNOW: Pakistan experienced unusual snowfall and heavy rains, resulting in the death of at least 35 people, including 22 children, reported BBC News
  • CORAL BLEACH: The world is on the brink of a fourth global mass coral bleaching event, which could see many tropical reefs killed by extreme ocean temperatures, reported Reuters. The Guardian reported that Australia’s Great Barrier Reef is facing its fifth mass coral bleaching event in eight years.
  • FUNDING THREAT: Individuals from global south climate groups that depend on finance from the German government “feel unable to criticise Israel’s military action in Gaza” due to pressure from their German-funded employers, Climate Home News reported.
  • MISSING MONEY: A UN official said that “Africa will be $2.5tn short of the finance it needs to cope with climate change by 2030”, noted Reuters, despite the continent producing the lowest emissions and experiencing the worst effects.
  • NEW ZEALAND LAWSUIT: An elder of the Ngāpuhi and Ngāti Kahu tribes “won the right to sue seven New Zealand-based corporate entities”, including fuel, coal and gas companies and dairy exporters, for their contribution to climate change, noted the Guardian.
  • NOTHING TO SEE HERE: The UK’s spring budget announcement was one of the “least green budgets in recent years” experts told the Guardian, with disappointment around electric vehicles and North Sea oil and gas. Carbon Brief had all the details.

2 billion

The amount of land in hectares that has been degraded by human activity over the past 500 years, reported Bloomberg.


Latest climate research

  • A Nature Climate Change study found that, while climate change drives population growth in lizards “when trees are present”, deforestation could reverse this effect and even exacerbate the negative impacts of climate change.
  • Under an additional 1C of warming, around 800 million people in the tropics will live in areas where “heavy work should be limited for over half of the hours in the year” due to the heat, a One Earth review paper found.
  • The severe “Tinderbox drought” in southeast Australia, which preceded the country’s largest wildfires on record from 2019-20, was intensified by human-caused climate change, according to a Science study.

A Trump election win could add 4bn tonnes to US emissions by 2030. With images of Trump and Biden.

A victory for Donald Trump (red line) in November’s US presidential election could lead to an additional 4bn tonnes of greenhouse gas emissions by 2030, compared with Joe Biden’s plans (blue line), new Carbon Brief analysis revealed. It is based on an aggregation of modelling by various US research groups. For context, 4bn tonnes of greenhouse gases is equivalent to the combined annual emissions of the EU and Japan, or the combined annual total of the world’s 140 lowest-emitting countries. “Regardless of the precise impact, a second Trump term that successfully dismantles Biden’s climate legacy would likely end any global hopes of keeping global warming below 1.5C,” the analysis added.

Spotlight

Female climate activist Angel Arutura

Angel Arutura, a social and climate justice activist in Northern Ireland, passionate about “connecting people and the planet” through social media.

On International Women’s Day, Carbon Brief speaks to Angel Arutura, a social and climate justice activist in Northern Ireland passionate about “connecting people and the planet” through social media.

Carbon Brief: How long has environmental activism been part of your life?

Angel Arutura: I’ve always been interested in the world around me, but it goes back to school, where geography was a subject that grabbed me. My teacher made lessons engaging and I became interested in how different parts of the world are affected by issues. I think my mixed-race heritage also helped. I have a multifaceted identity so, naturally, it made sense for me to think about how actions from the global north affected communities in the global south. I’m half Irish, half Zimbabwean, so I’ve been able to see that not just from an academic standpoint, but an emotional standpoint. Since then, I’ve been committed to connecting people to our true nature of love and protection and harbouring that loving connection for the people and the world around us.

CB: How has your identity as a woman shaped your activism, particularly your identity as a Black woman?

AA: I really started being vocal with my activism around the time of the Black Lives Matter protests in 2020, where the conversation was heavily on social justice. Growing up in a 98% White country, I experienced a lot of racism and my experience as a Black woman living in Ireland has been overwhelmingly negative. I rejected my Zimbabwean culture, my heritage, for so long. I went through a transformation at 17 where I started to connect with my heritage and it was through those years of self-reflection that I was able to speak at the protests. That’s when I found my voice. But, I thought to myself, hold on. Why are we just talking about social justice here? From then, I talked about the intersectionality of climate and social justice. As a Black woman, the driving power behind this was, in a weird way, finding that self-love.

CB: Why is it important to lift up the voices of women, particularly women of colour, when it comes to climate change?

AA: The majority of the time, when people talk about climate change and sustainability, they only talk about the exploitation of the planet. Think about fast fashion and women’s rights violations, and how those brands do sustainability initiatives and all this greenwashing. But how can you talk about the exploitation of the planet and not also the exploitation of women in the global south? The climate crisis, social justice, women’s rights, it’s all interconnected. An intersectional approach is the only one we need to take when it comes to climate change. It’s imperative if we want to create real, sustainable change. One of the best ways we can do this is through storytelling, in particular, elevating and uplifting the voices of the most vulnerable, especially those from the global south. And, unfortunately, that is women.

Watch, read, listen

SOUND WAVES: A three-part Sky documentary narrated by David Attenborough, revealed – amid glunking elk, popping grouse and laughing insects – how harnessing the sound of fish could be a vital tool to help save coral reefs.

‘FOLKLORIST’: Grist spoke to a “folklorist” about how community, culture and tradition are vulnerable to, but may also hold solutions for, climate change.

REPORTING FOR DUTY: In the face of extreme heat, “chief heat officers” in Sierra Leone and Mexico explain what this rare role entails in BBC World Service’s The Climate Question podcast.

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.”
