The Atlantic meridional overturning circulation (Amoc), a critical component of the global climate system, is at risk of collapse, with new research indicating a significantly higher likelihood than previously thought. This current system plays a vital role in regulating global climate patterns, and its collapse would have catastrophic consequences for Europe, Africa, and the Americas.Scientists have long been monitoring the Amoc's decline, which is primarily caused by rising air temperatures in the Arctic due to global heating. The Amoc's slowdown allows more rainfall to accumulate in the salty surface waters, making it less dense and further slowing the sinking, creating a feedback loop.The research, published in Science Advances, combined real-world ocean observations with climate models to determine the most reliable predictions. The findings suggest an estimated slowdown of 42% to 58% by 2100, a level almost certain to end in collapse. This is a concerning development, as a collapse would shift the tropical rainfall belt, plunge western Europe into extreme cold winters and summer droughts, and add 50-100cm to already rising sea levels around the Atlantic.Experts, including Dr. Valentin Portmann and Prof. Stefan Rahmstorf, emphasize the gravity of the situation, with Rahmstorf warning that the 'pessimistic' models, which show a strong weakening of the Amoc by 2100, are unfortunately the realistic ones. He added that he is increasingly worried that the Amoc shutdown tipping point may be passed in the middle of this century, which is quite close.The Amoc's collapse would have severe impacts on global climate patterns, and scientists stress that it must be avoided at all costs. The research highlights the need for urgent action to mitigate the effects of climate change and prevent such a catastrophic event.

Pakistan dispatched a mixed fleet of fighter and support aircraft to King Abdulaziz Air Base in Saudi Arabia’s Eastern Province on Saturday, marking the first visible military action under the mutual defence agreement signed in September 2025. The Saudi Ministry of Defence confirmed the landing, noting the deployment aligns with the collective defence clause that obliges each signatory to treat an attack on the other as an attack on itself. At the same time, Islamabad is hosting direct US‑Iran negotiations aimed at halting weeks of regional fighting triggered by Iran’s missile and drone strikes on Gulf targets after the US‑Israeli killing of Supreme Leader Ali Khamenei on 28 February. Foreign Minister Ishaq Dar told reporters he personally warned Iranian leaders in early March that Pakistan must honour its obligations to Riyadh. Tehran, seeking assurances that Saudi soil would not be used for attacks against it, received such guarantees, Dar added. Despite these diplomatic overtures, Iranian attacks on Saudi facilities – including key bases and a US embassy building – have persisted. In early March, Pakistan’s army chief, Field Marshal Asim Munir, flew to Riyadh to discuss measures to curb Iranian strikes within the framework of the defence pact. Four days before the jet deployment, Prime Minister Shehbaz Sharif phoned Crown Prince Mohammed bin Salman, pledging that Pakistan would stand “shoulder to shoulder” with Saudi Arabia. The two leaders also agreed to accelerate a $5 billion Saudi investment package earmarked for Pakistan. Saudi Finance Minister Mohammed al‑Jadaan met Sharif, Dar and Munir in Islamabad on Saturday, underscoring the economic dimension of the partnership. Saudi Arabia hosts roughly 2.5 million Pakistani workers, whose remittances are vital to Pakistan’s fragile economy, and has repeatedly provided financial assistance. Security analyst Imtiaz Gul told Al Jazeera the deployment was not intended as a military escalation but as a “messaging tool” to remind Tehran of Pakistan’s treaty obligations. “Three jets won’t make much of a difference militarily,” he said, noting Saudi Arabia’s own sizable air force. Michael Kugelman, senior fellow for South Asia at the Atlantic Council, described the move as “a risky gambit.” He warned that if Iran refuses concessions, Pakistan could be drawn closer to Saudi Arabia, potentially invoking the defence pact in a renewed conflict.

US President Donald Trump has announced that countries supplying Iran with military weapons will face immediate 50% tariffs on all goods sold to the United States, with no exemptions. This move comes hours after Trump agreed to a two-week ceasefire with Tehran.In a social media post, Trump stated that 'A Country supplying Military Weapons to Iran will be immediately tariffed, on any and all goods sold to the United States of America, 50%, effective immediately. There will be no exclusions or exemptions!'However, experts have raised questions about the legal authority behind Trump's announcement, as the Supreme Court struck down his use of the International Emergency Economic Powers Act (IEEPA) to impose broad global tariffs in February. The IEEPA has been used extensively for decades to back financial sanctions against Iran, Russia, and North Korea.Rachel Ziemba, adjunct senior fellow at the Center for a New American Security, told Al Jazeera that 'it's a lot more complicated to do that after IEEPA was struck down. There's no immediate policy lever and authorisation that is available for the US to do that. So they need either an act of Congress or need to adapt some other trade tool.'Trump did not specify which countries could face punitive tariffs, but China and Russia have helped Iran build military capacity to counter US and Israeli pressure. The US imports from Russia have fallen sharply since the invasion of Ukraine in 2022 and the wave of financial sanctions imposed on Moscow.Josh Lipsky, vice president and chair of international economics at the Atlantic Council, said that 'this is a China-related threat, the way I read it. And China will read it that way.' However, he also noted that Trump was unlikely to follow through with new tariffs in the near term because that would derail his planned trip to Beijing to meet with Chinese President Xi Jinping in mid-May.

Cheng Li-wun, chairwoman of Taiwan’s main opposition party the Kuomintang (KMT), used a high‑profile trip to mainland China to advocate for renewed dialogue with Beijing. On Wednesday she laid a wreath at Sun Yat‑sen’s mausoleum in Nanjing, invoking the revolutionary’s legacy of “equality, inclusiveness and unity” as a moral foundation for cross‑strait reconciliation. Her visit marks the first time a KMT leader has set foot in China in ten years. Cheng said the core values of Sun’s ideal—"all under heaven are equal"—should guide efforts to promote reconciliation and regional prosperity across the Taiwan Strait. During the trip Cheng also expressed hopes to meet Chinese President Xi Jinping, framing the potential encounter as a diplomatic test that could demonstrate the effectiveness of dialogue over deterrence. The timing of the trip is notable. It comes amid heightened friction between Taipei and Beijing, with China continuing to assert sovereignty over Taiwan while refusing to engage with President William Lai Ching‑te, whom it labels a “separatist”. Amid concerns that a distracted United States may be less able to guarantee Taiwan’s security, some Taiwanese voters view a thaw in relations as attractive. Wen‑ti Sung, a non‑resident fellow at the Atlantic Council’s Global China Hub, told Al Jazeera that a cordial photo‑op between Cheng and Xi could bolster the KMT’s argument that dialogue is more effective than military deterrence. Domestically, Cheng’s outreach occurs as Taiwan’s opposition‑controlled parliament has stalled a proposed $40 billion increase in defence spending. She acknowledged Taiwan’s democratic evolution, referencing the legacy of the “White Terror” period, while also praising China’s recent development achievements. The governing Democratic Progressive Party (DPP) sharply criticized the trip, accusing the KMT of undermining national security. Party spokesperson Wu Cheng argued that if the opposition truly seeks stability, it should stop blocking the defence budget increase. Neither Beijing nor Taipei formally recognises the other’s government, leaving any dialogue fragile and heavily politicised. Cheng’s visit therefore represents both a symbolic gesture toward historic ties and a contested move within Taiwan’s polarized political landscape.

Pakistan's diplomatic efforts have yielded a significant breakthrough, securing a temporary ceasefire between the US and Iran. The development comes after intense negotiations led by Pakistan's Prime Minister Shehbaz Sharif and Army Chief Asim Munir.The crisis had escalated to a point where Pakistan's government and military were deeply concerned about the potential consequences for the country's economy, defense, national security, and sectarian harmony. A defense pact with Saudi Arabia meant that if Riyadh entered the war, Pakistan would be drawn into it as well.Behind the scenes, Munir and Asim Malik, the country's head of army intelligence and national security adviser, played a crucial role in mediating the ceasefire. Munir's strong personal rapport with US President Donald Trump and his longstanding relationship with Iran's Revolutionary Guards were instrumental in brokering the deal.China emerged as a key player in the negotiations, with Pakistani officials claiming that Beijing directly encouraged Iran to accept a ceasefire, promising to act as a guarantor of Iran's safety in any talks. This included assurances that Iranian leaders would not be assassinated if they traveled for negotiations.The ceasefire deal was secured by 4am in Islamabad, with both the US and Iran agreeing to a temporary and fragile truce. Michael Kugelman, south Asia fellow at the Atlantic council, described it as Pakistan's 'biggest diplomatic win in years'.Pakistani officials have expressed concerns that Israel and the United Arab Emirates could still try to sabotage the peace process. However, the successful brokering of the ceasefire has been hailed as a 'shining moment' in Pakistan's history and a 'first step' towards peace.

Spain's coastal towns are taking proactive measures to prepare for tsunamis, a threat that has been historically underestimated. The town of Chipiona, located on the Atlantic coast, has become Spain's first 'tsunami-ready' community, recognized by the Intergovernmental Oceanographic Commission (IOC) of UNESCO in 2024. Chipiona's mayor, Luis Mario Aparcero Fernández, emphasizes the importance of public awareness and education in tsunami preparedness. The town conducts annual evacuation drills, and information boards have been installed to inform residents and tourists about what to do in case of a tsunami. The town's tsunami-ready status is part of a larger regional goal to establish 25 tsunami-ready communities by the end of this year and prepare all communities at risk by 2030. Jorge Macías, a tsunami modeller at the University of Málaga, stresses that preparedness is key, as the Mediterranean will experience a tsunami of at least a metre in height in the next 30 to 50 years with '100% certainty'. Spain's national tsunami warning system can detect an offshore earthquake and compute an initial assessment within three to five minutes. However, in the Mediterranean, this may leave only minutes to evacuate. Juan Vicente Cantavella, the director of the National Tsunami Warning System in Spain, notes that tsunami wave height is often underestimated, and even small waves can cause significant damage. Despite progress in some areas, much of the Costa del Sol remains in the earlier stages of planning, with sparse public signage and unclear evacuation routes. Miriam García, a geomorphologist and urban planner, highlights the vulnerability of Spain's Mediterranean coast, which was built without considering tsunami risks. The article concludes that preparedness is not about predicting the day and time of a tsunami, but about choosing not to be surprised when nature eventually repeats what history and geology say it will.

A humpback whale, approximately 10 metres long, has become stranded for the third time on Germany's Baltic coast. The mammal, believed to be male, appeared weakened and sick on Sunday, struggling to find a route back to the Atlantic.**The prognosis for the whale's survival is grim**, according to Burkard Baschek, a marine scientist. The whale's breathing frequency has reduced, and it no longer exhibits reactions to nearby vessels.Till Backhaus, the environment minister of Mecklenburg-Western Pomerania, established a 500-metre restricted area around the animal to give it a chance to rest and hopefully free itself. However, **the chances of success are relatively slim**, according to Baschek.The whale was first spotted in the Baltic on 3 March and reported stranded on a sandbank last week. Authorities used an excavator to deepen a channel and boats to create waves to help free the mammal, which was nicknamed Timmy. Despite being freed once, it became trapped again on Sunday.**The whale's respiratory rate has dropped considerably**, and it is not moving, according to Stephanie Gross of the Institute for Terrestrial and Aquatic Wildlife Research. Even if the whale frees itself again, it would need to navigate narrow straits and approximately 310 miles to reach relative safety.Humpback whales are not native to the Baltic, and experts suspect that the young whale followed a shoal of fish or became disoriented by the noise of a submarine. **The lack of salt concentration and nutrition in Baltic waters makes it difficult for humpbacks to survive in the long term**.

In 1986, thrash metal reached a critical point with landmark albums from Slayer, Megadeth, and Metallica. However, across the Atlantic, a group of teenagers were forging their own path in the genre. Kreator, Sodom, Destruction, and Tankard, dubbed the 'big four' of German thrash metal, were faster and meaner than their American counterparts.These bands made up for their lack of finesse and professionalism with sheer aggression. Destruction vocalist and bassist Marcel 'Schmier' Schirmer notes that they focused on writing songs that 'punched hard' rather than striving for musical perfection.The German thrash metal scene was marked by its rough and violent approach, with bands drawing inspiration from English heavy metal albums and American thrash metal bands like Slayer. The scene was also influenced by the political climate of the time, with the presence of the Berlin Wall and the Cold War.Bands like Formel 1 from East Germany, who released their live album Live Im Stahlwerk in 1986, were also part of the thriving metal scene. Despite the challenges faced by these bands, including limited resources and censorship, they managed to create a lasting impact on the metal genre.Today, bands like Kreator, Sodom, and Destruction continue to tour and produce new music, with Kreator's 16th album, Krushers of the World, and Destruction's upcoming US tour with Overkill and Testament. The legacy of German thrash metal remains strong, with its unbridled aggression and brutal sound continuing to influence metal musicians to this day.
