A Landmark Summit Sets the Stage for a Global Fossil‑Fuel Phase‑outGovernments in a coalition of 59 countries gathered in Santa Marta, Colombia, to draft voluntary 'roadmaps' that detail how each nation will end production and use of coal, oil and gas. The talks, co‑hosted by Colombia and the Netherlands, aim to move climate ambition from slogans to concrete policy.Voluntary National Roadmaps Proposed at Colombia’s Climate CoalitionThe summit asked participants to develop national plans that map out the transition away from fossil fuels, with the first draft released by Colombia during the meeting. France became the first developed country to publish a full roadmap, signalling broader uptake.Scale of the “Coalition of the Willing”: GDP, Energy Demand and Fossil SupplyRepresents > 50 % of global GDP.Accounts for nearly 33 % of worldwide energy demand.Controls roughly 20 % of global fossil‑fuel supply.Why This Shift Challenges the Traditional UN Climate ProcessUnlike the three‑decade‑old UN negotiations, the Colombian talks focus on export‑related emissions and the role of fossil‑fuel producers, gaps that the Paris‑agreement NDCs have left open. Irene Vélez Torres, Colombia’s environment minister, warned that existing NDCs allow producers to sidestep the climate impact of their exports.What Comes Next: Roadmap Adoption, Financing and Global ExpansionCountries will receive technical assistance to flesh out their plans, while a new scientific panel will advise on feasibility. Future meetings, including a second conference slated for early next year in the Pacific, will aim to broaden participation and lock in financing for debt‑strapped nations.

The Stark Divide in War Cost EstimatesUnited States Defense Secretary Pete Hegseth has clashed with American lawmakers over the cost of war on Iran in his first appearance on Capitol Hill since the conflict – now into its third month – broke out. The Pentagon told a hearing of the House Armed Services Committee that the US had spent $25bn on its war on Iran, largely on munitions and equipment maintenance. But Democratic leaders and several economists believe that number to be a significant underestimate, with actual costs potentially reaching between $630bn and $1 trillion.The Pentagon's Limited Financial DisclosureThe Pentagon's acting comptroller, Jay Hurst, who testified alongside Hegseth and Joint Chiefs of Staff Chairman Dan Caine, presented the estimated figure of $25bn to the committee. "We will formulate a supplemental [on additional funding], through the White House, that will come to Congress once we have a full assessment of the cost of the conflict," Hurst said, promising to provide a cost breakdown later.The estimated figure only reflects "the costs of the war," Hurst explained, factoring in "munitions expended in that total and other operational costs." This figure is significantly smaller than the $200bn initially requested by the Trump administration for the war and the $11.3bn reported for just the first six days of fighting in March.The Economic Ripple Effects Beyond Direct Military SpendingAs the US continues with its blockade of Iranian ports and Tehran controls the Strait of Hormuz, gas prices in the US have hit a new high at $4.23 a gallon – the highest since 2022, when Russia invaded Ukraine. The Brent crude benchmark has been trading above $120, leading to a 40 percent rise in gas prices compared to pre-war levels.Representative Ro Khanna claimed the war would cost about $631bn – or some $5,000 per household – to the US economy due to increased gas and food prices. "Your $25bn number is totally off," Khanna told Hegseth, highlighting the administration's failure to account for broader economic impacts.The rising cost of living has also affected Trump's approval rating, hitting a record low in his second term with only 22 percent of Americans approving of his handling of cost of living, according to a Reuters/Ipsos poll.Hidden Costs of War: Infrastructure and Long-term ImplicationsThe US claimed earlier that it struck more than 13,000 targets over the first 39 days of fighting with Iran. For context, the US fired more Patriot missiles in the first four days of the Iran war than it supplied to Ukraine over the past four years, with each missile costing $4m.However, the economics and impact of the war extend far beyond the worth of bombs and missiles. One major expense is reconstructing and repairing damaged assets. After the US-Israeli strikes assassinated former Supreme Leader Ali Khamenei, Iranian strikes caused damage to US military camps in Kuwait, alongside other military bases in the UAE, Saudi Arabia, Jordan, and Bahrain.Earlier this month, NBC News quoted six US officials noting that Iran damaged US military bases and equipment in the Middle East far worse than publicly acknowledged. The damages alone could lead to billions of dollars in repairs, with one report estimating that repairs to the US Navy Fifth Fleet headquarters in Bahrain could cost $200m alone.Historical Precedents and Future ProjectionsHarvard economist Linda Bilmes had estimated in February 2006 that the Iraq war would cost the US $3 trillion, when the George Bush administration was telling the public that fighting would cost $50bn. Twenty years later, Bilmes ended up with among the most accurate predictions, as the Iraq war's total cost is now estimated at $2 trillion."Wars always cost more than expected. Throughout history, those who get into wars tend to be optimistic about the cost and about the length of time it will take," Bilmes noted. "It is hard to measure the exact cost. But based on what we know now, it [the current Iran war] is costing about $2bn a day in short-term, upfront costs, which is the tip of the iceberg."Beyond immediate expenses, Bilmes highlighted long-term costs including veterans' care and restocking weapons inventory. "I am certain we will reach one trillion dollars for the Iran war," she concluded. Meanwhile, the Trump administration has asked for a $1.5 trillion defense budget for next year – a 42 percent increase, or the largest expansion in military spending since World War II.

The Shadow Fleet's Triumph in HormuzOn March 11, the Thai cargo ship Mayuree Naree was struck by two projectiles while crossing the Strait of Hormuz, one of the world's most important waterways located between Iran and Oman. A fire broke out in the engine room, and while 20 sailors were rescued, three remained trapped inside the stricken vessel. Their remains were found weeks later when a specialised rescue team boarded the vessel, which had run aground on the shores of Iran's Qeshm island.At about the same time, a "shadow fleet" of tankers continued to navigate the very same waters safely. Operating with fake flags, disabled signals and unspecified destinations, this covert armada survived because it operates outside the traditional rules of maritime trade.Iran threatened to block "enemy" ships passing through the Strait of Hormuz – a crucial chokepoint for a fifth of the world's oil – in the wake of the United States-Israeli war launched on February 28. Soon, navigation through the strait was disrupted amid fears of attacks.Following a temporary ceasefire on April 8, the United States imposed a full naval blockade on Iranian ports on April 13. Theoretically, traffic through the strait should have come to a complete halt.However, tracking data reveals a remarkably different reality.How Iran's Covert Maritime Network OperatedAn exclusive Al Jazeera open-source investigation tracked 202 voyages made by 185 vessels through the strait between March 1 and April 15, navigating both under fire and across blockade lines.To understand how the strait operated under extreme pressure, Al Jazeera's Digital Investigative Unit monitored the waterway daily, cross-referencing vessel International Maritime Organization (IMO) numbers with international sanction lists from the US Office of Foreign Assets Control (OFAC), the European Union, the United Kingdom and the United Nations. An IMO number is a unique seven-digit figure assigned to commercial ships.Of the tracked voyages, 77 (38.5 percent) were directly or indirectly linked to Iran. Notably, 61 of the ships transiting the strait were explicitly listed on international sanctions lists.The investigation divided the conflict into three distinct phases to map the fleet's behaviour:Phase 1: Open War (March 1 – April 6): 126 ships crossed the strait, peaking at 30 vessels on March 1. Among these, 46 were linked to Iran.Phase 2: The Truce (April 7 – 13): 49 ships crossed during this fragile pause. More than 40 percent of these vessels were tied to Iran, including the US-sanctioned, Iranian-flagged Roshak, which successfully exited the Gulf.Phase 3: The US Blockade (April 13 – 15): Despite the explicit naval blockade, 25 ships crossed the strait.Breaking the Blockade: Tactics and TechniquesWhen the US blockade took effect, the shadow fleet adapted immediately.The Iranian cargo ship "13448" successfully broke the blockade. Because it is a smaller vessel operating in coastal waters, it lacks an official IMO number, allowing it to evade traditional sanction-monitoring tools. The vessel departed Iran's Al Hamriya port and reached Karachi, Pakistan.Similarly, the Panama-flagged Manali broke the blockade, crossing on April 14 and penetrating the cordon again on April 17 en route to Mumbai, India.The investigation uncovered widespread manipulation of Automatic Identification System (AIS) trackers. Vessels such as the US-sanctioned Flora, Genoa and Skywave deliberately disabled or jammed their signals to hide their identities and destinations.The Global Network Behind Fake FlagsTo obscure ultimate ownership, the shadow fleet heavily relies on a complex web of "false flags" and shell companies. The investigation identified 16 ships operating under fake flags, including registries from landlocked nations like Botswana and San Marino, as well as others from Madagascar, Guinea, Haiti and Comoros.The operational network managing these ships spans the globe. Operating firms were primarily based in Iran (15.7 percent), China (13 percent), Greece (more than 11 percent) and the United Arab Emirates (9.7 percent). Notably, the operators of nearly 19 percent of the observed vessels remain unknown.Economic Impact on Global Energy MarketsDespite the intense military pressure, energy carriers dominated the traffic, with 68 ships (36.2 percent) transporting crude oil, petroleum products and gas. Ten of these tankers were directly linked to Iran. Non-oil trade also persisted, with 57 bulk and general cargo ships crossing during the open war phase, 41 of which were tied to Tehran.Before the war, at least 100 ships crossed the Strait of Hormuz daily. Today, a staggering 20,000 sailors are trapped on 2,000 ships across the Gulf – a crisis the International Maritime Organization described as unprecedented since World War II.A shadow Iranian fleet, meanwhile, has been navigating seamlessly as part of a parallel maritime system born from 47 years of US sanctions on Tehran. Washington slapped sanctions on Tehran following the 1979 Islamic revolution that toppled the pro-Washington ruler Shah Mohammad Reza Pahlavi. The two countries have had no diplomatic ties since 1980.Future Implications for Global Trade and SanctionsThe success of Iran's shadow fleet in evading the US naval blockade demonstrates the limitations of traditional sanctions and naval blockades in the modern era. As technology enables more sophisticated evasion techniques, international bodies may need to develop new monitoring and enforcement mechanisms to maintain effective sanctions regimes.The persistence of trade through the Strait of Hormuz, despite military conflict and blockades, underscores the critical importance of this waterway to global energy markets. Any prolonged disruption would have significant economic implications worldwide, potentially accelerating efforts to develop alternative trade routes and energy sources.Meanwhile, the humanitarian crisis affecting thousands of sailors stranded in the Gulf highlights the unintended consequences of geopolitical conflicts on civilian maritime operations, potentially prompting new international agreements on protecting neutral shipping during conflicts.

The New Tool for Obesity-Related Disease Risk A new tool developed by UK researchers can help identify individuals most at risk of obesity-related diseases, such as type 2 diabetes, gout, and stroke. This tool uses a type of AI called interpretable machine learning to analyze data from nearly 200,000 participants of the UK Biobank project. How the Tool Works The researchers applied the AI tool to data from participants with a BMI of 27 or greater, identifying 20 health, lifestyle, and demographic features that could predict the 10-year risk of 18 different obesity-related complications. These features include age, sex, total cholesterol, and creatinine levels. The Data Analysis The team tested the validity of the tool, dubbed Obscore, using UK Biobank data and datasets from two independent health studies. The results showed that participants with the same age, sex, and BMI can have very different risks for various obesity-related conditions. The Impact Analysis The tool could help inform strategies for prioritizing who should receive weight-loss interventions, particularly in cases where access to NHS treatments is limited. According to Prof Nick Wareham, the tool is not about extending the use of particular therapies, but rather about developing and validating a score that can help with more rational resource allocation. The Prediction The researchers believe that their tool could be useful for prioritizing individuals who would benefit most from weight-loss medications. However, Naveed Sattar, a professor of cardiometabolic medicine at the University of Glasgow, noted that substantial further development and validation will be required before such an approach can be translated into routine clinical practice.

Inside the high‑risk world of Giffords Circus’s new ‘Waterfield’ showThe latest production, Waterfield, is being built at the farm‑based headquarters in Fennells Farm, Gloucestershire. Founder Toti Gifford describes it as the most dangerous show the troupe has ever attempted, with acts that push physical limits and a set that includes a pub‑on‑wheels replica of a local inn.Hand‑crafted sets and family‑run operations fuel the spectacleAll structures – from the circus tent to the new wagon – are built by hand using reclaimed farm materials.The site also hosts a restaurant and hotel under construction, pending planning permission.Director Cal McCrystal, a veteran of the troupe, adds theatrical storytelling to the circus format.Financial and audience impact of the daring productionWhile exact ticket‑sale figures are not disclosed, the company’s 26‑year history shows steady growth, now supporting a blended family of four children and a multinational crew. The addition of a unique pub‑wagon and upgraded facilities is expected to boost seasonal revenue and attract a broader audience seeking immersive experiences.Why this daring turn matters for the UK live‑performance sectorThe show exemplifies a resurgence of boutique, family‑run circuses that compete with large‑scale productions by offering authenticity and raw danger. Its success could encourage other small troupes to invest in handcrafted venues and narrative‑driven acts, diversifying the cultural offering beyond traditional theatre.What’s next for Giffords Circus and the broader circus renaissanceWith the new winter venue and hotel slated to open in the coming years, Giffords Circus aims to cement its place as a year‑round attraction. If Waterfield draws critical acclaim, it may set a benchmark for high‑risk, story‑centric circus productions across the UK and inspire a new wave of innovative live entertainment.

Trump Urges Tehran to Surrender as Day 62 UnfoldsDonald Trump declared the U.S. blockade of Iranian ports a success and told Iran to “just give up”.Iranian Parliament Speaker Mohammad Bagher Ghalibaf dismissed the blockade’s impact, saying no oil wells have exploded and storage is not full.U.S. officials, including Treasury Secretary Scott Bessent, face criticism for “junk advice” on the policy.Escalating Standoff Over the Strait of HormuzThe blockade aims to force Iran’s oil storage to capacity, potentially halting production; analysts estimate current storage covers only ~20 days of output.Russian President Vladimir Putin warned Donald Trump not to resume attacks on Iran, calling the cease‑fire extension “the right one”.Key negotiation dead‑locks remain: Iran’s nuclear programme, $20 bn of frozen assets, and Tehran’s demand for $270 bn in war reparations.Oil Prices Surge and War Costs Climb Above $25 bnBrent crude jumped above $119 a barrel, WTI above $105, pushing global oil to >$120 per barrel.U.S. Defense Secretary Pete Hegseth estimated the war’s cost at “less than $25 bn” after 60 days.Washington seized nearly $500 m in Iranian crypto assets under “Operation Economic Fury”.Global Economic Ripple Effects and Regional TensionsOPEC entered “crisis mode”; the UAE plans to exit the group amid the energy shock.Asia‑Pacific economies face higher inflation as fuel and food prices rise; the Asian Development Bank cut growth forecasts.Bahrain’s revocation of citizenship for 69 individuals sparked Iranian condemnation, adding diplomatic strain in the Gulf.What the Next Weeks May Hold for the Iran ConflictAnalysts expect a gradual tightening of the blockade, with a possible acceleration in May if storage fills.U.S. officials are preparing for a “long blockade” to pressure Tehran into a non‑nuclear deal.Potential diplomatic pathways include renewed U.S.–Iran talks, but success hinges on resolving nuclear and reparations disputes.

Brenton Tarrant, the Australian white supremacist who killed 51 people in the March 15, 2019 Christchurch mosque shootings, has lost his appeal to overturn his conviction and life‑without‑parole sentence.The Court of Appeal’s Unanimous Rejection of Tarrant’s AppealNew Zealand’s Court of Appeal ruled on Thursday that Tarrant’s appeal was “utterly devoid of merit”. A three‑judge panel concluded that his evidence about mental state and prison conditions was inconsistent and contradicted observations from prison officials and mental‑health assessments. The court affirmed that his guilty pleas were voluntary and not the result of coercion.Numbers Behind the Verdict: Charges, Sentencing and Prison Terms51 murder charges40 counts of attempted murder1 charge of committing a terrorist attackSentenced in August 2020 to life imprisonment without paroleTarrant, now 35, had previously argued that “torturous and inhumane” detention conditions impaired his rational decision‑making at the time of his pleas.What the Ruling Means for Survivors, Legal Precedent and Counter‑Terrorism PolicyLawyers for the survivors and families described the decision as a “huge relief”, noting that a new trial would have forced them to relive the trauma of March 15. The judgment reinforces the robustness of New Zealand’s legal framework for handling terrorism‑related crimes and sets a clear precedent that appeals based on alleged prison mistreatment will face stringent scrutiny.Looking Ahead: No Further Legal Recourse and Potential Legislative ResponsesWith the Court of Appeal’s dismissal, Tarrant has exhausted domestic avenues for appeal; any further challenge would require a petition to the Supreme Court, which is unlikely to be granted. The case may spur continued discussion on prison conditions for high‑profile terrorists and could influence future legislative reviews of New Zealand’s counter‑terrorism and mental‑health assessment protocols.
