Breathing Earth's Ancient PastMore than 2bn years ago, during the Paleoproterozoic era, the Earth's atmosphere began to fill with free oxygen, enabling the rise of aerobic life and, ultimately, humans. This Great Oxidation Event is now being experienced firsthand by visitors to the Museum of Old and New Art (Mona) in Tasmania, where French-Swiss conceptual artist Julian Charrière has created an extraordinary installation that allows people to inhale oxygen that has been trapped in iron ore since that ancient time.When Charrière came up with the concept for what would become 'Breathe,' Mona's owner David Walsh not only approved the project but created a bespoke space for it, recognizing the unique intersection of science, art, and human experience that the installation represents.The Science Behind the Ancient OxygenThe installation is a marvel of scientific ingenuity and artistic vision. Charrière has sourced ancient iron ore from Australia's Pilbara region, which is processed daily in an on-site laboratory. The water is extracted from the ore using specialized machinery, then put through a Hofmann apparatus—a piece of scientific equipment that electrolyzes water—to liberate the trapped oxygen molecules.This pure, ancient oxygen is then released into a specially designed room where visitors can breathe it in, creating a direct connection to the beginning of life on Earth. As Charrière explains: 'I want people to get all the way back to the beginning of the earth. It's like a time machine.' The installation is designed as a solitary experience, with visitors accessing a vault-like corridor reminiscent of a mining drift, flanked by raw sandstone and lined with deep red rocks from the Pilbara.The Immense Timescale of the InstallationThe timescale involved in 'Breathe' is almost incomprehensible. The oxygen visitors inhale has been trapped in iron ore for over 2.4 billion years—since the Great Oxidation Event that transformed Earth's atmosphere and enabled the development of complex life forms. This installation literally connects each visitor to the primordial beginnings of our planet's atmosphere.As visitors walk through the tunnel, the temperature drops as they approach a high-ceilinged cylindrical room, an underground windowless tower where lighting depends on the amount of sun that can be reflected through a small opening above. Walking over tiles made of polished ancient tiger ore, they circle a floor-to-ceiling clear glass tube that houses the Hofmann apparatus. It is here, at a small opening, that visitors have their closest access to Charrière's pure, ancient oxygen.Redefining the Art-Science Experience'Breathe' represents a groundbreaking fusion of scientific methodology and artistic expression, challenging traditional boundaries between disciplines. The installation creates a profound personal experience that connects visitors not just to art, but to the very essence of life on Earth.What makes this installation particularly powerful is its claim that each visitor is the first human being to ever inhale that specific oxygen. As Charrière explains: 'You are breathing something which is so pure and has not been touched by any being before you... And the beauty of the piece is you will carry it until you die. You're going to become a small part of this installation and you become a big part of the great oxygen cycle, and you will only finally free this oxygen once... once you're going in the other world.'This installation is part of a broader trend in contemporary art that incorporates scientific processes and concepts, creating works that are both intellectually stimulating and viscerally impactful.The Future of Scientific Art Installations'Breathe' is opening alongside Charrière's major new exhibition 'Hard Core,' which showcases both the ambition and scientific curiosity of the Berlin-based artist. Individual elements of 'Hard Core' have been exhibited elsewhere in the world, including at the Venice Biennale, but the full exhibition finds its perfect home at Mona, with its exposed rock, industrial aesthetic, and fusion of science with art.As museums and galleries continue to seek innovative ways to engage audiences, installations like 'Breathe' point to a future where art and science are not just displayed together but are fundamentally intertwined in the creative process. This approach has the potential to create more immersive, educational, and thought-provoking experiences that challenge visitors to see the world—and their place in it—in new ways.Charrière's work demonstrates how art can make abstract scientific concepts tangible and personal, creating connections across vast stretches of time and space. As our understanding of the universe expands, art installations like 'Breathe' will play an increasingly important role in helping us process and relate to these profound concepts.

The Shift in BHP's Climate Strategy BHP, the world's largest miner, has been a significant player in the global mining industry. However, recent internal documents leaked to the Guardian and the ABC's Four Corners program have revealed that the company is backtracking on its climate action plans. The Leaked Documents The leaked documents, dubbed the BHP files, show that the company has halted or delayed several key projects aimed at reducing emissions. These projects include: A 50-megawatt solar farm and 20MW battery at its Jimblebar mine, which was effectively shelved soon after being approved and funded by the board in mid-2023. A huge system of almost 500MW solar, wind and battery that could power a small city, which has been significantly delayed and will not progress in its current form until 2031 at the earliest. An iron ore processing plant that could have prevented 1.7m tonnes of emissions a year, which was dumped despite being described as 'well-aligned' with its climate transition action plan. The Impact on Climate Goals BHP's decision to backtrack on its climate action plans has raised concerns among experts and environmental groups. The company's failure to urgently decarbonize could put national climate targets, including a 43% cut below 2005 levels by 2030, in doubt. The Future Outlook BHP has stated that it is still focused on its emissions reductions goals and has reduced emissions by 36% on 2020 levels. However, experts argue that the company's actions are not in line with its public commitments, and it needs to take more drastic measures to achieve its climate goals.

BHP Acknowledges Delay in WA Iron‑Ore Decarbonisation PlanA senior BHP executive admitted that the company’s push to cut emissions in Western Australia has been postponed. Tim Day, head of BHP’s WA iron‑ore operations, cited slow progress in electric trucking and rail technology as the main obstacle to replacing diesel, the biggest source of the mine’s emissions.Emission Reduction Targets and Financial Incentives1.7m tonnes of CO₂ could have been avoided each year by a scrapped iron‑ore processing plant – roughly the impact of 350,000 cars.BHP’s internal memo notes a “low probability of success” for its net‑zero by 2050 goal, despite a 36% drop in global emissions driven largely by projects outside Australia.The company received $622m in diesel tax concessions from the federal government, while paying under $9m for excess emissions under the safeguard mechanism last year.Implications for Australia’s Climate Goals and Mining LicenceThe slowdown threatens Australia’s national emissions‑reduction targets, as BHP’s WA operations remain a major diesel‑intensive source. Internal documents stress that rapid decarbonisation is “effectively underpins [WA iron ore’s] licence to operate, sustain and grow.” Premier Roger Cook warned that big miners have an “important moral obligation” to decarbonise, linking climate action to the social licence to operate.Future Outlook for BHP’s Net‑Zero RoadmapInternal scenarios consider initiating a transition as late as 2035 or 2040, highlighting the risk of reputational damage and potential derailment of the net‑zero pledge. Analysts note that BHP has done little to curb emissions from its Australian assets, suggesting that without stronger policy pressure or a shift in government subsidies, the company may continue to rely on diesel‑fuelled haulage for years to come.

The LeadBHP, one of the world's largest mining companies, faces increasing scrutiny over its environmental commitments as part of The Guardian's "The BHP Files" series. The article questions whether the mining giant's sustainability initiatives match its actual operations, particularly in the context of the ongoing climate crisis.The Environmental Claims vs. RealityThe cartoon illustration by Fiona Katauskas visually represents the tension between BHP's public environmental commitments and its actual practices. The artwork suggests that despite the company's "green" branding, its core operations continue to contribute significantly to environmental degradation. This visual commentary highlights the skepticism many environmentalists feel toward large corporations' sustainability claims.The Mining Industry's Environmental ImpactBHP's operations span multiple continents and extract various resources, including coal, iron ore, copper, and petroleum. The mining industry as a whole faces significant criticism for its contribution to carbon emissions, habitat destruction, and water pollution. Despite increasing pressure from investors, regulators, and environmental groups, the pace of meaningful change in the sector remains slow.Investor and Regulatory PressureRecent years have seen growing pressure on BHP and other mining companies to address their environmental impact. Shareholder resolutions demanding stronger climate action have gained traction, while regulators in some jurisdictions have implemented stricter environmental standards. However, the company's continued investment in fossil fuel projects has raised questions about the sincerity of its environmental commitments.The Future of Sustainable MiningThe article comes at a critical time for the mining industry, which faces the dual challenge of meeting global resource demand while transitioning to more sustainable practices. BHP has announced various initiatives to reduce its carbon footprint, including investments in renewable energy and plans to reduce emissions from its operations. However, critics argue these measures are insufficient given the scale of the company's environmental impact.

The Jimblebar Beneficiation Project: A Missed Opportunity for DecarbonizationBHP has quietly abandoned plans for a major iron ore processing facility near its Jimblebar open-cut mine in the Pilbara. The project, which was well advanced in 2025, aimed to improve the purity of iron ore to meet global demand, particularly from China. Despite being internally rated as having "excellent social value" and being "well-aligned" to shareholder-endorsed climate plans, the mining giant decided to cancel all further work on the plant.The Economic Trade-off: Marginal Returns vs. Climate GoalsThe decision to scrap the Jimblebar plant was driven by a strict assessment of marginal economics. BHP determined that the project would struggle to compete for capital against other potential investments. This cancellation is part of a broader pattern where the company is either shelving or delaying major projects designed to reduce emissions, including a 50-megawatt solar and 20MW battery project that had board approval.Capital Allocation: The miner is prioritizing projects with higher immediate returns over those that offer long-term environmental benefits.Fleet Strategy: Despite pledging to electrify its fleet, BHP has continued purchasing polluting diesel trucks for Pilbara operations.Quantifying the Impact: Scope-Three Emissions and Market PremiumsThe Jimblebar facility was not just a logistical upgrade; it was a strategic tool for decarbonization. By providing higher quality iron ore, the plant would have allowed steelmakers to reduce their emissions intensity, which is one of the cheapest methods for the industry to cut carbon output.The economic and environmental stakes were significant:Emission Reduction: The project was estimated to reduce scope-three emissions by 1.7m tonnes a year.Comparative Impact: This reduction is equivalent to taking more than 350,000 cars off the road, representing about three-quarters of the entire annual emissions from BHP’s Western Australian iron ore division.Market Premium: Higher quality ore allows BHP to charge customers a premium, creating a potential win-win scenario that was ultimately deemed too marginal.Broader Implications for Australia's Safeguard MechanismThe leaked documents, dubbed the "BHP files," raise serious questions about the efficacy of Australia’s Safeguard Mechanism. This federal policy requires the country's largest polluting industrial facilities to cut greenhouse gas emissions intensity year on year. BHP's decision to delay or cancel green investments suggests that the current policy framework may not be strong enough to compel major miners to prioritize decarbonization over short-term profitability.Future Outlook: The "Net Zero" DilemmaBHP's recent actions indicate a potential shift in its timeline for achieving net-zero goals. By war-gaming options to significantly delay major investments, the company is signaling that its 2050 emissions target may be more aspirational than operational in the near term. Investors and climate advocates will be closely watching whether BHP can reconcile its climate commitments with its capital allocation strategy as global pressure mounts.

The Government’s Push to Nationalise Scunthorpe Steelworks On Monday, 12 May 2026 the Labour government announced legislation to bring the Scunthorpe plant of British Steel into public hands, framing the move as essential for national resilience. Starmer argued that "strong nations need to make steel" and used the proposal to shore up his leadership ahead of the upcoming king's speech. Historical Ownership and the Road to 2025 State Control 1859: First iron ore discovered in Scunthorpe, sparking the region's steel boom. 1951: Nationalisation of the UK steel industry. 1953: Privatisation after two years. 1967: Second wave of nationalisation. 1970s: UK steel production peaks. 1988: Privatisation under Margaret Thatcher. 2007: Ownership passes to Tata Steel (India). 2016: Greybull Capital buys the loss‑making works for £1 and revives the British Steel brand. 2019: Chinese firm Jingye Steel takes control. 2025: Government recalls Parliament for a historic Saturday sitting to pass legislation aimed at taking control. Despite these changes, the plant’s two historic blast furnaces – nicknamed Anne, Bess, Victoria and Mary – remain operational and are widely regarded as at the end of their economic life. Financial Losses and Valuation Dispute £350 million cumulative loss recorded by Jingye up to the end of 2023. £1 billion figure demanded by Jingye to settle its debts. £100 million offer from the government rejected by Jingye. 4,000 employees currently on the payroll. 2,700 jobs at risk if the plant were to close. 50% protectionist tariff announced to support domestic steel demand. The government has locked Jingye out of operational control but left it with economic ownership, meaning a compensation assessment by an independent valuer is expected. Strategic Implications for UK Industrial Sovereignty The Labour administration stresses the need to preserve "primary steelmaking" – the ability to produce steel from iron ore – as a matter of national security. The plant faces multiple pressures: Global overcapacity driven by cheap Chinese steel. Higher energy costs for UK producers compared with European peers. Ageing blast‑furnace infrastructure requiring costly upgrades. Keeping the Scunthorpe works running is presented as a way to maintain a domestic supply chain for critical sectors and to signal to foreign investors that the UK will protect strategic assets. Potential Paths for British Steel Under Government Ownership Officials, led by Business Secretary Peter Kyle, are favouring a transition from blast furnaces to cleaner electric‑arc furnaces, a shift that would require "hundreds of millions of pounds" in state subsidies. Meanwhile, private investors are signalling interest: Michael Flacks, a turnaround specialist, has expressed potential acquisition interest. Sev.en Global Investments, a Czech group, is also reported to be weighing a bid. Any future owner would likely need to keep the existing blast furnaces operational during the transition period to protect short‑term employment, while the government pursues longer‑term decarbonisation goals.

The Surveillance Operation New Zealand’s military said a surveillance aircraft observed what it suspected was North Korea breaking international sanctions in a “possible ship-to-ship transfer of illicit goods”, while conducting monitoring over the Yellow Sea and East China Sea. Details of the Incident The exchange of goods at sea between vessels was captured by one of its long-range P-8A Poseidon reconnaissance aircraft in international waters near North Korea. The surveillance aircraft was patrolling for possible North Korean violations of United Nations sanctions at sea. The exchange was observed among 35 “vessels of interest” in the area. Implications of the Breach “The evidence captured of activities that were occurring in the East China and Yellow Seas allows authorities to take action against ships that may still be operating in contravention of [UN resolutions],” New Zealand’s Air Component Commander, Air Commodore Andy Scott, said in a statement. Background on North Korea Sanctions North Korea has been under UN sanctions since 2006 after carrying out its first nuclear weapons test. UN sanctions were significantly expanded in 2016 and 2017 to include a range of exports and ship-to-ship transfers. North Korea typically uses ships to smuggle refined petroleum imports and to export its coal, iron ore and sand, which help fund its nuclear and ballistic missile programmes. Despite the restrictions, North Korea continues to trade goods with a handful of countries, including China, Iran, and Russia. New Zealand's Role in Enforcement New Zealand has been a member of the US-led Pacific Security Maritime Exchange since 2018, which monitors North Korea’s violation of international sanctions through smuggling and illicit maritime activity.

Gina Rinehart, Australia's richest person, has been dealt a significant blow with a court ruling that her company, Hancock Prospecting, must pay hundreds of millions of dollars in royalties to a rival mining family, Wright Prospecting.The Western Australian supreme court decision, which came on Wednesday, found that Wright Prospecting was entitled to a half share of royalties from the Hope Downs iron ore project, a joint venture between Rio Tinto and Hancock Prospecting.Hope Downs is a major mining project that exports around 45 million tonnes of iron ore annually from Australia's north-west. The court's ruling is a significant setback for Rinehart, who has been embroiled in a long-standing dispute with the Wright family over mining assets and royalties.The case, which began in 2010, has been a complex and lengthy battle, with multiple parties involved and over 4,000 documents submitted during the trial. The judge's findings, which ran to over 1,650 pages, noted that the dispute required a 'lengthy, diverse, and detailed reconstruction of events' dating back to the 1960s.Rinehart's company, Hancock Prospecting, has estimated that the historical payments to Wright Prospecting could be around $14 million per year, while the Wright camp estimates the amount could near $1 billion. The amount Hancock Prospecting and Rio Tinto are liable to pay will be the subject of a future hearing.The decision has been claimed as a partial victory by all parties involved, with Wright Prospecting welcoming the ruling and Hancock Prospecting declaring victory on the issue of ownership rights over the valuable assets.The 16-year court case may still have many years yet to play out, with neither side ruling out appealing against the verdict.

Gina Rinehart, Australia's wealthiest person, faces a potentially significant loss of wealth and control over her Pilbara iron ore empire as a court verdict looms in Perth. The Western Australian supreme court judgment will determine whether Rinehart must share the spoils of some of Hancock Prospecting's most lucrative iron ore projects with the family of her late father's business partner, Peter Wright.The dispute centers on the lucrative Hope Downs mining complex near Newman in north-west Western Australia, a joint venture between Hancock Prospecting and Rio Tinto, which delivered a $832m profit to Hancock Prospecting in 2025. The Wright family heirs claim they are entitled to an equal share of the 2.5% royalties coming from Hope Downs to Hancock Prospecting.Hancock Prospecting rejects the claim, arguing it undertook all the work and bore the financial risk of development, making it the legitimate owner of the Hope Downs assets. The judgment, expected to be appealed regardless of the outcome, may also impact Rinehart's children, who have accused their mother of an 'egregious fraud' against them.Rinehart's company and Hancock Prospecting have rejected all claims, with Rinehart's lawyers arguing that her actions were done to right an historic wrong by her father. The court's decision will also inform a separate federal arbitration process that will decide how Hancock Prospecting's shares are divided between the family.In a related development, Hancock Prospecting's latest annual report shows that more than $6.4bn in dividends have been placed in reserve pending the outcome of arbitration.
