China has passed 1,000 gigawatts of installed solar capacity, the largest amount ever built by any country. Observers note the total roughly equals the entire electricity generating capacity of the United States from all sources. The milestone highlights the pace of China's renewable energy build-out and its widening lead over other nations in solar deployment.

The United Nations has declared that solving climate change is a 'decisive test of global solidarity', framing collective action on emissions and adaptation as the defining challenge for international cooperation. The statement underscores growing pressure on governments to deliver coordinated commitments, with the UN urging countries to set aside divisions and treat the climate crisis as a shared responsibility requiring joint effort.

Iran says diplomacy is the only way forward after Donald Trump rejected a peace plan, keeping tensions over the country's nuclear programme and regional standoff in the spotlight.

North Korean soldiers captured or transferred from the war in Ukraine have been brought to South Korea, raising questions about their legal status and future. Reuters outlines the options ahead, including possible defection procedures, questioning by South Korean intelligence, and diplomatic complications between Pyongyang, Kyiv and Seoul over the men's fate.

UN Secretary-General António Guterres delivered his final address to the UN General Assembly, warning that superpowers cannot solve the world's problems on their own. Speaking in New York, he argued that global challenges like climate change demand multilateral cooperation rather than reliance on a few dominant states. The speech, covered by the Guardian, is being shared widely as a closing message from a leader known for pressing major powers to act together.

North Korean soldiers who fought alongside Russian forces in Ukraine and were captured have been transferred to South Korea, raising questions about their future. Attention is focused on whether Seoul will accept them as defectors, how they will be processed, and what their transfer means for Kyiv, Moscow and Pyongyang as the war continues.

Ukraine says its military launched Operation Vivaldi, an assault on Russian positions using explosive-laden unmanned armoured vehicles, and captured more than 250 Russian soldiers. Ukrainian outlet Ukrainska Pravda reported the operation, publishing photos and video it says show the strike and the detainees. If confirmed, the number of prisoners would rank among the larger single captures of the war. Details on the location and Russian casualties remain limited, and Russia has not commented.

Ukraine's digital transformation minister Mykhailo Fedorov has announced plans to deploy an 'army of robots' on the battlefield, according to Le Parisien. The initiative aims to replace human soldiers on the front line with unmanned ground and aerial systems, reducing casualties in the war against Russia. Fedorov, who has driven Ukraine's rapid wartime adoption of drone and autonomous technology, framed the effort as the country's new strategic bet to offset its manpower shortage.

South Korean soldiers were injured in an explosion in the Demilitarized Zone, and officials assess the blast was most likely caused by a North Korean landmine. The incident has drawn attention to ongoing dangers along the heavily fortified border, where mines remain scattered decades after the Korean War. Authorities are investigating the exact circumstances of the explosion and the soldiers' condition.

California is testing and evaluating solar panels built over irrigation canals, an approach that generates renewable energy while shading water and reducing evaporation. Early lessons from pilot projects are offering insight into how the technology performs at scale, and the findings are drawing attention as the state weighs ways to expand clean energy and conserve water at the same time.

Iran says it remains committed to a diplomatic solution after US President Donald Trump rejected a proposed peace plan. The rejection, reported widely by international outlets including Reuters and Al-Monitor, has drawn attention to the future of negotiations between Washington and Tehran. Iranian officials maintain they still favour talks, while the US stance leaves the path to an agreement uncertain.

South Korean soldiers patrolling the Demilitarized Zone are believed to have been injured by landmines of North Korean origin, according to the headline. The incident would raise fresh concerns about mines still buried along the heavily fortified border and about safety conditions for troops monitoring the area. Details about the number of soldiers hurt or the severity of their injuries were not provided.

New data on global electricity generation shows coal remained the world's largest single source in 2024, producing about 34% of all power. Wind and solar together supplied 15%, a sharp rise from just 4% a decade earlier. The figures, presented in charts drawn directly onto an interactive map, are drawing attention for how clearly they show both coal's persistence and renewables' rapid growth.

German outlet Der Spiegel has released the second part of its 'Inside Russia' documentary series, presenting what it describes as exclusive insights into Vladimir Putin's isolated dictatorship. The film explores daily life, political repression and the atmosphere inside Russia, and is drawing large international attention amid ongoing interest in how ordinary Russians experience the war in Ukraine and tightening Kremlin control.

Electric vehicles have outsold gasoline and diesel cars in Europe for the first time, according to reports by Korean media including Chosun Ilbo. The milestone marks a turning point for the European auto market, highlighting how quickly battery-powered cars have moved from the margins to mainstream dominance across the continent.

Industry analysts expect more US banks to grow past the trillion-dollar asset mark as consolidation across the American banking sector accelerates. A handful of giants, including JPMorgan Chase, already hold more than a trillion dollars in assets, and further mergers are seen pushing additional institutions toward that threshold. Observers are weighing what ever-larger banks mean for competition and regulation.

New figures indicate that global solar installations reached around 690 gigawatts in 2025, underlining the continued rapid expansion of solar power worldwide despite market pressures. The record pace of additions reinforces expectations that solar remains the fastest-growing source of new electricity generation capacity, though analysts note growth rates are slowing compared with previous years.

Electric vehicle sales are surging across Europe, rising 52% as gasoline prices hit record highs of roughly $10 a gallon. The report highlights how expensive fuel is pushing European drivers toward electric cars faster than expected. Commenters are debating whether high fuel costs or policy incentives are the real driver of the boom, and what it means for automakers and consumers elsewhere.

The US Commerce Department has moved to block companies from stockpiling solar equipment ahead of December 4, when new tariff rules are expected to take effect. The decision aims to prevent importers from racing to build inventories before higher duties apply. The move is likely to affect solar developers and suppliers who had been accelerating shipments to lock in lower costs.

Child malnutrition remains one of Africa's biggest health challenges, and experts argue that food aid alone cannot solve it. Writing in The Conversation, commentators stress the need for broader measures such as stronger health systems, nutrition education, clean water and long-term food security policies alongside emergency relief to tackle the crisis sustainably.

Posts claim that OpenAI's GPT-6, referred to as 'Astra', has decrypted an Enigma message that had gone unsolved since 2005, referencing the Breaking German Cipher Machine challenges site. Discussion centres on the claim that an AI model succeeded where human codebreakers had failed for two decades. The evidence available is a single headline, and details about how the message was cracked have not been confirmed from these posts.

Ukraine has announced Operation Vivaldi, saying its forces attacked Russian troop positions using explosive-laden unmanned armoured vehicles and took more than 250 Russian soldiers prisoner.
