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.

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.

Pacific leaders rail at climate finance failures after pre-COP trip to Tuvalu

Published

on

After witnessing the effects of sea-level rise in the low-lying island nation of Tuvalu, Pacific leaders on Tuesday used the pre-COP31 summit in Fiji to voice their frustration at the difficulties they have experienced in tapping the global climate finance system.

A small group of government leaders, climate negotiators and heads of development banks and climate funds took a trip to Tuvalu’s Funafuti atoll on Tuesday morning, travelling by road over land just 10-20 metres wide to visit a project that is building barriers to keep the sea from the land.

They then flew to Fiji for the pre-COP summit, where several Pacific leaders said they had been let down by the insufficient quantity, bad terms and slow speed of international finance to help them adapt to a warming climate that is bringing higher oceans, drought and more powerful storms to their shores.

“Right now, our islands are like a canoe that has been rammed by a massive foreign ship. Our canoe is taking on water, we are sinking, and what is the world’s response?” asked Palau’s President Surangel Whipps Jr.

“They hand us a tiny patch to cover a gaping hole,” he continued, “but the bureaucratic process just to receive that patch is so slow that the water fills the hole while we wait. Then to rebuild the vessel so that we can survive the next storm, we are offered loans, debt that adds weight to a sinking boat packaged in red tape so thick we can barely access it. And while we wait, the water continues to fill.”

Pacific leaders and Australia called again on governments to invest in the new Pacific Resilience Facility (PRF), which has been designed by the Pacific Islands Forum and is seeking $500 million in investments by COP31 in November.

It has around $180 million so far, but did not receive additional pledges during the UN General Assembly in New York. The PRF aims to invest to generate annual returns which it can give to projects like water tanks for drought-hit communities.

Witnessing sea level rise

The annual pre-COP gathering is usually a low-profile technical meeting of climate negotiators. But this year, Australia – which is the president of negotiations at COP31 – partnered with the Pacific to introduce a “leaders segment” in an attempt to shine a spotlight on climate issues affecting the region.

Fourteen government leaders – from Australia, Timor-Leste, Mauritius and the Pacific – made the trip. They were joined by the European Union’s climate commissioner Wopke Hoekstra, the heads of the Green Climate Fund and the Asian Development Bank and former Australian prime minister Julia Gillard.

On their return to Fiji, Solomon Islands Prime Minister Matthew Wale told the pre-COP leaders roundtable that the sea level rise they had witnessed was personal for him.

“Tuvalu was not just a site visit for me. I saw the story of my own saltwater people,” he said, adding that he, his daughter and his grandfather had lost their houses to sea level rise and that three-quarters of his electorate live on land that will be underwater in the next 30 years.

From the other side of the world, Antigua and Barbuda’s environment minister Michael Joseph said Tuvalu’s problems felt similar to those of his own Caribbean islands. “I saw vulnerable communities… just metres from the sea and people determined to remain on their land, preserve their culture and way of life,” he said.

A group of Fijian schoolchildren told the leaders it was not just sea level rise the Pacific struggles with but also heatwaves, droughts and storms, which worry their families and prevent them from learning.

Climate finance red-tape

Several Pacific leaders criticised the world’s leaders for not doing enough to combat climate change. Cook Islands Prime Minister Mark Brown expressed disappointment that only two non-Pacific leaders had come to the pre-COP, a fact Australian media widely picked up on to label the event a flop and question its A$20 million (US$14m) price tag.

“We’ve heard a lot of numbers these last two days,” Brown said. “Let me share one of my own. More than 50 invitations extended to world leaders… to see for themselves what high emissions are doing to our nations and our ocean – an ocean that covers nearly one-third of the Earth’s surface.”

    He called for more climate finance for the Pacific, asking “if the world is prepared to assess our suitability for climate finance, why is it not equally prepared to scrutinise whether those responsible for delivering it are meeting their obligations?”

    Like Palau’s president Whipps, Naoero’s President David Adeang criticised the red tape that is hindering access to climate finance as well as a lack of money, complaining especially about “complicated procedures, heavy reporting, delays in approval and disbursement”.

    Adeang added that “the way we assess vulnerability matters”, adding that it should be measured by more than income. Naoero, for example, is classified by the World Bank as high-income, restricting which climate finance it is eligible for.

    Action plan to improve access

    On Thursday, the Australian government will present a statement and action plan on improving access to climate finance for small island developing states and least developed countries, which it is asking other countries and organisations to endorse.

    The statement addresses some of these Pacific complaints as well as acknowledging that progress has already been made on simplifying access by multilateral development banks and climate funds.

    In Fiji, Asian Development Bank head Masato Kanda said his institution is “tailoring our finance and operations to island realities” because “your children and their children should be able to grow old in the countries their ancestors have called home for millennia”.

    The executive director of the Green Climate Fund (GCF), Mafalda Duarte, said that the GCF-backed coastal adaptation project leaders visited in Tuvalu shows that “climate finance works” although – as the project took eight years to implement – “it takes time, and therefore we have no time to waste”.

    Australia calls for optimism

    While Pacific leaders expressed concern that the world is set to blast past its agreed 1.5C warming limit, endangering their nations, Australia’s Prime Minister Anthony Albanese called for “optimism”. “If people think there is no hope, then they will not strive to get the change that we need,” he said.

    He said that when he attended his first COP in 2005, Australia’s renewable energy target was 2%. Its target is now 82% renewable electricity by 2030.

    While Albanese promoted Australia’s success at electrifying homes and businesses and rolling out renewables, he has been criticised by climate campaigners for extending the production of fossil fuels, including coal – largely for export.

    France’s Minister for Ecological Transition Monique Barbut defended the European Union’s climate action at the pre-COP meeting. She said the continent was heating up and reducing emissions faster and providing more climate finance than anywhere else in the world.

    “It is time for all major emitters to step up and do their fair share” on climate finance, she said. Most developing countries with large emissions have fiercely resisted joining the club of climate finance donors, arguing they have played a disproportionately small historic role in causing climate change.

    Barbut, as well as Palau’s president Whipps, called for the next flagship scientific assessment report of the Intergovernmental Panel on Climate Change (IPCC) to be finished by COP33 in 2028, in time to inform the next global stocktake of national climate action.

    This timeline has been opposed by countries like India, Saudi Arabia and China, who argue it would put an unfair burden on developing countries. Barbut said countries should “support the work of the IPCC rather than sabotage its calendar”.

    Barbut said that governments should agree at COP31 to aim to raise the share of “clean electricity” in final energy consumption to 35% by 2035. The Turkish and Australian governments have pushed for this goal although without specifying that the electricity should be “clean”. Barbut added that COP31 should also agree to cut emissions of methane, a particularly potent greenhouse gas.

    Coal mines and hypocrisy must not be Australia’s COP31 legacy

    Published

    on

    Jacynta Fa’amau is a Pacific campaigner at global grassroots climate movement 350.org and a secretariat member of Pacific Climate Warriors.

    The first thing that struck me was the sheer size of Queensland’s Saraji coal mine. Standing at the edge of the enormous pit, my brain scrambled for words as I scanned the earth’s open wound – a whole island could probably fit inside it.

    Looking down, I noticed footprints of an emu and a koala, pressed and dried in what was once a puddle – signs of how drought had driven animals in desperate search of water, so dangerously close to the coal trucks and heavy machinery ahead.

    Earlier this year, I joined a small group of Pacific Islanders on a journey through the Bowen Basin to learn from First Nations communities battling Australia’s mammoth coal industry. Of the more than 40 coal mines operating in the area, BHP & Mitsubishi Alliance’s Saraji mine is one of the largest. So it came as a painful shock to us when in August, the Australian government approved the mine’s extension just months after our visit.

      Witnessing coal extraction is devastating. It is bad enough to see what pillaging tonnes of coal can do to a mine’s immediate surroundings: dry creek beds, dwindling wildlife, denuded land. But to know that this coal will be shipped across the ocean, bring air pollution, and eventually lead to the destruction of Pacific islands thousands of miles away is another kind of heartbreak.

      Rising ocean waters

      I’m an Australian-born Samoan. In 2002, I visited my family home for the first time. My father took me to the rural community where generations of my family were raised. He did not have the words to describe how much has changed since rising ocean waters had taken away almost a third of the beach.

      I learned of how we had to relocate my great‑great‑grandparents’ grave to higher ground twice in the last 15 years. Of how my cousins have to paddle out further to sea to catch fish, since warmer waters have destroyed much of the reef. Of how the ocean crashes so close to my uncle’s home that he had to build a new house further away.

      We saw reflections of our own climate destruction in the Pacific when we shared these stories with our First Nations relatives at the edge of the Saraji mine. Murrawah Johnson and Teila Watson, both Birri Gubba and Gangulu women, made clear connections between their struggles and ours. “We don’t get to inherit our land and we don’t get to inherit our traditional roles. We are fighting a war on extinction,” Murrawah said.

      Coal extraction devastated their lands and cultures – totems have disappeared, fresh water has become scarce – while the effects of using it have devastated ours. “King tide, cyclones, all the violence that has been enacted on your country and people is because of the violence that has been allowed here, to us and our country,” Teila said.

      Wearing the mantle of climate leadership

      This week, Australia is assuming the mantle of climate leadership as co-president and head of negotiations of this year’s UN Climate Change Conference, COP31. It will lead on deliberating the summit’s priorities as world leaders and climate negotiators descend on Fiji and Tuvalu for the pre-COP meetings.

      Ironically, just days before the pre-COP began, the New South Wales Independent Planning Commission approved the largest-ever coal project the state has seen, set to emit an extra 800 million tonnes of carbon emissions. I joined the Pacific Climate Warriors and other communities in submitting about 4,000 appeals to oppose the project – yet these all fell on deaf ears.

        But the fight is not yet over. The project still requires federal approval to proceed, so every promise that Australia makes while at the helm of the climate talks counts. These promises will be measured against actual decisions it makes at home: to either lock us into more decades of climate pollution, or begin shutting down coal and gas once and for all.

        Pacific leaders have made it clear that countries must align their policies with the 1.5-degree warming goal, a limit that we already know will be breached within the decade. Any chance of keeping this still within reach requires an immediate end to fossil fuel expansion and concrete plans to phase out existing projects. But success will be an uphill battle if COP31’s own head of negotiations refuses to lead by example.

        Australia remains the second-largest coal exporter in the world. It is one of the very few industrialised countries under the Paris Agreement’s Annex I that still has no coal phase-out plan. Since 2022, the Albanese government has approved 37 new, expanded or extended coal, oil and gas projects. It is thus unsurprising that its own mitigation policies have been rated by Climate Action Tracker as “insufficient”, even without factoring in fossil fuel exports and related expansion.

        Keeping 1.5C alive

        Australia must course-correct to earn the mantle it has been given, especially by Pacific nations that backed the country’s bid for the COP31 co-presidency. As a first step, the government must end all coal expansion and explicitly declare a coal phase-out date. It’s the only way to show that it’s capable of leadership that moves beyond endlessly deliberating the “if”, and starts implementing the “how” of keeping the 1.5C target alive.

        The dread I felt staring down at the abyss on the edge of that coal mine months ago still exists. I carry it with me as I show up at the pre-COP to demand that leaders heed the calls of Pacific people. But it is tempered with resolve to keep our lands and communities alive. We remain steadfast in our efforts to secure an outcome that protects people everywhere and brings us back below 1.5 degrees as soon as possible.

        Race to host High Seas Treaty HQ heats up as Chile reaffirms bid

        Published

        on

        When José Antonio Kast took office as Chile’s new president in March, one of his first moves was to put the brakes on plans to expand two protected marine parks – raising doubts about the country’s high-profile bid to host the headquarters of the High Seas Treaty.

        But during the UN General Assembly last month, the right-wing leader reaffirmed his leftist predecessor’s ambition for Chile to host the landmark global pact, which came into effect in January and provides a legal framework to protect the waters of the high seas beyond national jurisdiction that cover about two-thirds of the world’s oceans.

        Hailing the country’s “maritime vocation”, Kast’s government said the bid to host the treaty’s secretariat in the port city of Valparaíso was state policy and testament to its commitment to multilateralism.

        “For the government of Chile, it is of high interest to achieve this recognition, and we will carry out all the efforts to obtain the necessary support,” Foreign Minister Francisco Pérez Mackenna was quoted as saying by local media.

          Tough competition from Chinese, Belgian bids

          But to garner the votes it needs, Chile must fend off competing bids by Belgium – which has proposed its well-connected capital, Brussels – and China, whose well-funded bid includes the provision of free premises in the coastal city of Xiamen and five years of free utility costs.

          Parties to the treaty, formally called the Agreement on Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ), will choose the headquarters at their first summit (COP1), in New York from January 11 to January 22, 2027. They will seek consensus, falling back on a two-thirds majority in successive secret ballots.

          Chile has offered to provide a restored waterside warehouse “at its own expense” as office space, pitching itself to developing countries as a Global South alternative to Europe-centred Brussels. Among richer countries, it is promoting its democratic credentials and greater transparency as an alternative to China.

          Rolling back environmental safeguards at home?

          While the South American country remains the top pick among environmental campaigners and other civil society groups, critics of Kast’s government say recent policy moves may make it harder for the country to garner the support it needs.

          On March 12, the day after Kast took office, the Environment Ministry withdrew 43 decrees awaiting legal approval, including a push to expand the Mar de Juan Fernández and Nazca-Desventuradas marine parks – vast protected areas in Chile’s Pacific Ocean waters. Both remain under review, the ministry told Climate Home News.

          The decrees also included an emission standard for coal power plants and regulations for Chile’s new biodiversity and protected areas service.

          What’s on the climate calendar for October 2026?

          A month after holding up the decrees, Kast questioned aspects of Chile’s urban wetlands protection law, suggesting it was sometimes an unjustified obstacle to much-needed housing development, and his administration has also sought to ease the rules on salmon farming in the world’s second-largest producer.

          In August, the Constitutional Court struck down the salmon farming reform after a challenge by opposition lawmakers and warnings from green groups including Greenpeace, which said it could help farms relocate into protected areas such as the Kawésqar National Reserve.

          Valparaíso mayor Camila Nieto, from former leftist President Gabriel Boric’s party, backs the bid to host the High Seas Treaty, but said she hoped “the government’s support also translates into public policies consistent with the goals of protecting and conserving the oceans”.

          “The decisions a country makes on environmental matters can influence international perceptions of its commitment to protecting the oceans. That is something we cannot ignore,” Nieto told Climate Home News.

          China’s bid stirs concerns over data access, fishing

          Chile’s past record on marine protection – it has protected 43% of its jurisdictional waters – could yet give it an edge.

          “Chile deserves it for its conservation record as a state. For more than 15 years Chile has been following this path,” Liesbeth van der Meer, executive director at conservation group Oceana in Chile, told Climate Home News.

          Concerns in some quarters about the rival bid by China – for example, over a potential conflict of interest due to the vast Chinese fishing industry – may also weigh in Chile’s favour, experts say.

          Chinese-flagged vessels did about 30% of detected high seas fishing between 2022 and 2024, according to an Oceana analysis of Global Fishing Watch data. China also sponsors five of the International Seabed Authority’s 31 deep-sea mining exploration contracts, more than any other country.

          The secretariat would host sensitive marine data, making transparency paramount, experts say.

          China says hosting the secretariat in Xiamen would help make the treaty more globally representative, fostering cooperation between rich and developing countries and aiding equitable access to marine science and technology.

          Wang Yi, China’s minister of foreign affairs, said in a statement that the country has “all along championed true multilateralism” and “firmly defended” UN institutions. Given Xiamen’s $38-billion ocean industry, the city lives up to the treaty’s “significance and promising future”, he added.

          Meanwhile, Chile is proposing the treaty’s first high seas marine protected area for the Salas y Gómez and Nazca ridges, a chain of more than 110 seamounts stretching about 4,000 km from off Peru to Rapa Nui (Easter Island) that is rich in endemic fish and other marine species.

          The ridges are “a true oasis of productivity”, said Carlos Gaymer, director of the Centre for Ecology and Sustainable Management of Oceanic Islands at Universidad Católica del Norte and co-author of a 2021 scientific review of the area.

          The water is so clear that phytoplankton thrive around 200 metres down, feeding zooplankton, small fish and, up the chain, sharks and seabirds. Whales, turtles and sharks use the ridges as “a real highway” across the Pacific, Gaymer said. Parts of the Nazca ridge are likely nursery grounds for jack mackerel and swordfish.

          Chile has already asked the body that regulates the industry in the area – the South Pacific Regional Fisheries Management Organisation (SPRFMO) – to close the ridges to all fishing vessels. According to Chilean data, more than 80% of fishing in the area involves Chinese vessels.

          Meeting on the Chilean request in early September, SPRFMO’s scientific committee agreed only to recommend closing the area to bottom fishing. SPRFMO’s commission will take the final decision at its next meeting, in early 2027.

          For Gaymer, Chile’s push to close the area to fishing should be seen as a “starting point” for the treaty proposal.

          “Every time there’s a new expedition, species new to science appear,” Gaymer said. “If you don’t protect areas like these … those species simply disappear from the planet.”
