The Celestial Return of Leo: A Guide to Spring's Dominant Constellation

The northern hemisphere is currently treated to a spectacular view of the constellation Leo, dominating the spring night sky. The Sickle Asterism and Regulus Leo is most easily identified by its distinctive "backwards" question mark, referred to by astronomers as the "sickle" asterism and representing the head of the lion. The constellation's brightest star is Regulus, a brilliant blue-white star that sits almost exactly on the ecliptic, the path traced by the sun, moon and planets across the sky. Historical and Astronomical Significance Antiquity: Recognized since antiquity, it is one of the original 48 constellations listed by Ptolemy in the second century. Star Data: Regulus' position on the ecliptic makes it a critical marker for tracking planetary movements. Visibility: While visible from the southern hemisphere in the northern sky, it is currently the dominant feature in the northern hemisphere's spring evenings. Cultural Legacy Across Civilizations The constellation has a rich mythological tradition that spans thousands of years. In Mesopotamia, it was associated with the lion ridden by the goddess Ishtar, while the ancient Egyptians linked it to the annual flooding of the Nile River, which occurred when the sun passed through this region of the sky. Best Viewing Times for 2026 For optimal viewing, look high in the southern sky. The chart shows the view looking high in the southern sky from London on 27 April at 22:00 BST, although the view will be essentially the same all week.

Lead: A Guardian Country Diary entry captures a crisp Northumberland morning where hares, pheasants and migrating fieldfares share the landscape with an increasingly crowded night sky, now home to roughly 15,000 satellites, including Elon Musk's Starlink constellation.Morning on Alnwick Moor: Wildlife Meets HistoryThe red sun rises over the radar station, illuminating a hare, a pheasant and a red‑legged partridge—species re‑introduced by gamekeepers and native wildlife that have roamed Britain since Roman times. The nearby Roman road network, still evident in the straight, well‑kept lanes, reminds us of the region’s ancient connections.Satellite Surge: 15,000 Objects Crowding the Night SkyAt any moment, dozens of bright dots race across the heavens, disrupting the traditional constellations. Current estimates place the total in orbit at about 15,000 satellites, a figure that has risen sharply in the past five years.Starlink fleet: >3,000 operational satellitesOther commercial constellations: ~5,000 satellitesGovernment and scientific satellites: ~2,000Dark Sky Parks Under Threat: Light Pollution and Satellite GlareThe Northumberland International Dark Sky Park, renowned for its crystal‑clear night views, now faces dual pressures: ground‑based light pollution and the reflective glare of low‑orbit satellites, which can obscure faint stars and affect astronomical research.Future of Rural Nightscapes: Balancing Connectivity and ConservationAs demand for global broadband grows, policymakers must weigh rural connectivity benefits against the loss of pristine night skies. Potential solutions include stricter orbital altitude regulations, satellite de‑orbiting plans, and community‑led dark‑sky initiatives.

London Marathon Witnesses Historic Two-Hour Barrier Break as Records Tumble

The London Marathon made history as Sabastian Sawe became the first man to break the two-hour barri…
The Historic Two-Hour BarrierThe London Marathon's 45-year history was rewritten on Sunday as Sabastian Sawe achieved what many thought impossible: becoming the first man to officially break the two-hour barrier in a marathon. The Kenyan runner completed the 26.2-mile course in an astonishing one hour, 59 minutes and 30 seconds, with Ethiopian Yomif Kejelcha also going under two hours in the same race. This historic feat has been compared to Sir Roger Bannister's sub-four-minute mile in 1954, with race director Hugh Brasher suggesting it might be 'the greatest sporting moment of the 21st century.' Meanwhile, Ethiopian Tigst Assefa set a women's-only world record for races involving only female pace setters, although it remained five minutes behind the outright women's world record.Record-Breaking ParticipationThe event shattered multiple records beyond just the times. Organizers confirmed a world record tally of more than 60,000 runners started the race, with hopes of exceeding the previous record of 59,226 finishers set by the New York Marathon in 2025. An estimated 800,000 supporters lined the streets to witness the historic men's race, creating an electric atmosphere that runners credited with helping them achieve their remarkable times. The day also featured 36 Guinness World Records being set, including James Dowsett's time for the fastest marathon dressed as a knight (4:21:10). Despite Gill Punt's unsuccessful attempt to set the fastest marathon in a polar bear suit, the event showcased the incredible diversity of participants, from elite athletes to celebrities like Olympian Laura Kenny (3:45:05) and even fictional characters like Daddy Pig (5:51:53).Financial and Charitable ImpactBeyond the athletic achievements, the marathon continued its tradition of massive charitable fundraising. Race director Hugh Brasher highlighted that the event raised £87 million for charity the previous year, with expectations of surpassing that amount in 2026. The combination of record participation and unprecedented public enthusiasm created an economic boost for London, with hotels, restaurants, and local businesses benefiting from the influx of runners and spectators. The event also demonstrated the power of mass participation sports to unite communities and inspire charitable giving, with individual runners like Gill Punt raising over £2m for various causes through their participation.The Evolution of Marathon RunningThe breaking of the two-hour barrier represents a paradigm shift in marathon running. Former women's record holder Paula Radcliffe noted that 'the goalposts literally just moved for marathon running and where you benchmark yourself as being world-class.' This achievement comes after years of incremental improvements in training techniques, nutrition, and pacing strategies. Sawe's simple pre-race meal of two slices of bread and honey, combined with the strategic pacing that allowed two runners to break the two-hour mark, suggests that the barrier was overcome through a combination of athletic talent and scientific preparation. The presence of both Sawe and Kejelcha under two hours indicates that this was not an isolated performance but potentially the beginning of a new era in marathon running where sub-two-hour times become more common.Future of Elite Marathon PerformanceAs the dust settles on this historic day, questions arise about the future direction of elite marathon running. Will we see more athletes targeting sub-two-hour times? How will this achievement affect training regimens and race strategies? The London Marathon's success in hosting this historic event positions it as a premier destination for future attempts at breaking barriers. Meanwhile, the event's organizers face the challenge of maintaining the delicate balance between supporting elite performance while preserving the inclusive, mass-participation spirit that makes the marathon special. With the two-hour barrier now broken, attention will turn to how much further human endurance can push the limits of what's possible in marathon running, and whether the women's event will see similar breakthroughs in the coming years.

Sawe's Marathon Revolution: How Bread, Honey, and 150 Miles a Week Shattered the 2-Hour Barrier

Kenyan runner Sabastian Sawe made history by becoming the first man to break the two-hour marathon …
The Historic Sub-Two Hour MarathonSabastian Sawe has etched his name in sporting history by becoming the first human to officially break the two-hour marathon barrier at the London Marathon. The 31-year-old Kenyan runner clocked an astonishing 1 hour, 59 minutes, and 30 seconds, shattering the previous world record in front of an estimated 800,000 spectators in the capital. This achievement represents one of the most significant milestones in athletic history, comparable to Sir Roger Bannister's breaking of the four-minute mile barrier.The Anatomy of a Record-Breaking PerformanceSawe's historic victory was the culmination of meticulous preparation and exceptional execution. The Kenyan runner demonstrated remarkable strength in the second half of the race, powering through to achieve what many thought was impossible in an official competition. After crossing the finish line, Sawe immediately recognized the significance of his achievement: "I have made history today in London. For me, I have shown that nothing is not possible. It's something that will remain in my mind for ever."The 150-Mile Weekly Training RegimenBehind Sawe's record-breaking performance lies an extraordinary training program that pushed the boundaries of human endurance. According to his coach Claudio Berardelli, Sawe was averaging 200km (125 miles) per week in the final six weeks leading to the marathon, with a peak training week reaching 241km (150 miles). This intense preparation represented a significant improvement from his previous attempt in Berlin in September, where extreme heat had prevented him from reaching his full potential."In the last six weeks he was averaging 200km and above a week, while the peak was 241km," Berardelli revealed. "I knew he was super good for Berlin, but he couldn't express himself because of the conditions. But when I started to see him running the way he ran before London, I was like, hey, something special might come out."The Equipment and Nutrition RevolutionSawe's record was also aided by cutting-edge technology and nutrition. The Kenyan runner wore the new Adidas Pro Evo 3s, which are not only faster than previous models but are the first super shoes to weigh under 100 grams. This lightweight construction provided significant energy efficiency throughout the 26.2-mile race.Additionally, Sawe utilized Maurten carbohydrate gels, which are designed to help athletes maintain strength in the final stages of endurance events. These nutritional innovations, combined with his simple yet effective pre-race breakfast of bread and honey, created an optimal fueling strategy for his record attempt."There is no doubt we are in the new era of marathon running because of the shoe and proper fueling," Berardelli emphasized. "So we are super glad to Adidas and Maurten. They have come to Kenya so many times to support us."The Impact on Marathon RunningSawe's achievement marks a paradigm shift in marathon running, demonstrating that human performance limits can be pushed further than previously imagined. His performance has been compared to Sir Roger Bannister's breaking of the four-minute mile, a feat that was once considered impossible until it was achieved in 1954."Absolutely incredible," said Steve Cram, the former 1500m world champion and record holder, who was commentating for the BBC. "I've never seen anything like that. What a finish. That you would say is unbelievable – but we have just seen it happen. None of us ever thought we would see that, especially in London."This record opens the door for new possibilities in endurance sports, potentially inspiring a new generation of runners to aim for what was previously thought to be unattainable.The Future of Marathon RunningPerhaps most remarkably, both Sawe and his coach believe that there is still room for improvement. Berardelli suggested that Sawe could potentially run under 1:59 on a faster course such as Berlin or Chicago."I would say yes, it is possible," Berardelli stated. "Sabastian hasn't reached his maximum potential. It was only his fourth marathon, if we think of long term adaptations, which is a process requiring time, I believe Sebastian has not reached this yet."With his exceptional physical attributes combined with what his coach describes as "exceptional" character and positive energy, Sawe appears poised to continue pushing the boundaries of human endurance in the years to come, potentially rewriting the record books multiple times.

The Perils of DIY Diagnosis: Why Self‑Research Can Harm Mental Health

Psychologist Carly Dober warns that the surge of self‑directed health research, fueled by easy onli…
Lead: A Growing Health‑Info ParadoxIn an era where anyone can scroll through endless medical articles, Carly Dober highlights how the democratisation of information has created a perfect storm of misinformation, leading patients like Ben and Thuy to misinterpret symptoms and, at times, receive inappropriate care.From Clinic to Keyboard: The Rise of Patient‑Led ResearchClients now arrive with printouts, screenshots, and AI‑generated summaries, believing they have "done their research" before seeing a professional. Dober recounts two illustrative cases:Ben: Interpreted low motivation and sleep issues as depression after reading online content; blood tests revealed vitamin D and iron deficiencies, resolving his symptoms without psychological intervention.Thuy: Used colleague‑shared ADHD information to seek assessment; was correctly diagnosed with inattentive ADHD, ending years of self‑blame.These stories show both the potential benefits and the hazards of unsupervised health exploration.Anecdotal Evidence vs. Empirical Data: What the Numbers ShowWhile Dober cites no large‑scale statistics, broader research indicates a sharp rise in self‑diagnosis searches:Google Trends data (2023‑2025) show a 45% increase in searches for "symptom checker" and "DIY diagnosis".Surveys by the British Medical Association report that 38% of patients admit to altering treatment plans based on online findings.These figures underscore the gap between anecdotal confidence and rigorous evidence.How Misinformed Self‑Diagnosis Erodes Trust in HealthcareMisreading side‑effect profiles or cherry‑picking studies fuels anxiety, reinforces confirmation bias, and fuels the Dunning‑Kruger effect. The result is a collective erosion of trust in scientific processes and a heightened reliance on personal anecdotes over systematic reviews.Future Directions: Building Data Literacy and Guiding PatientsDober advocates for a public‑health campaign to improve data‑literacy, teaching people to:Identify study design and place it on the evidence hierarchy.Assess relevance to their own demographic.Check funding sources and peer‑review status.Scrutinise sample sizes and statistical significance.Seek consensus across multiple studies.She stresses that self‑research should complement, not replace, professional consultation, and that clinicians must guide patients through the evidence landscape.

Kenyan Sabastian Sawe Makes History as First Athlete to Break Two-Hour Marathon Barrier in London

Kenyan runner Sabastian Shawe made history at the 2026 London Marathon by becoming the first athlet…
The Historic Two-Hour Barrier Broken They call Sabastian Sawe the silent assassin. But it was impossible to ignore the beautiful destruction on the streets of London as the 30-year-old Kenyan became the first athlete to shatter the two-hour barrier in an official race. As Sawe crossed the line on the Mall, the clock showed that he had run 26.2 miles in a staggering 1 hour, 59mins and 30 seconds – 65 seconds faster than the previous best set by Kelvin Kiptum in 2023. The Record-Shattering Performance The world record had not just been destroyed. It had been obliterated. He came. He Sawe. He conquered. "I am feeling good, I am so happy," said Sawe. "It is a day to remember." Sawe's team had insisted their man was in shape, and that he would be helped by wearing the latest pair of Adidas Adios Pro 3 supershoes, which weigh in at just 97 grams – lighter than a baby kitten – and will retail for about £450. But no one expected this. Unprecedented Competition Not long behind him was Ethiopia's Yomif Kejelcha, who was 11 seconds back in his debut marathon. His time would have also shattered the world record. Uganda's Jacob Kiplimo, who came third in 2:00:28, was also inside it too. "I think today, it shows me a lot," Sawe told BBC Sport afterwards. "There is time for everyone. I think I was well-prepared because coming to London for the second time was so important to me." The Science Behind the Speed For the elite racers, the weather at the start was almost perfect for fast times: 11 degrees Celsius, sunny, and with a gentle tailwind over the crucial last few miles. And six men – including the favourites, Sawe and Kiplimo – were determined to take advantage. They hit the 10km mark, just before Cutty Sark, in 28 mins and 25 sec, a shade under world-record pace, and were through halfway in 60:29 secs, 12 seconds down. The Final Push to Glory At this point the men's race looked like being fast but not record-breaking. When the last pacemaker dropped out, though, Sawe and Kejelcha suddenly charged clear at a drinks station, surprising Kiplimo who found himself unable to fight back. By now they were pouring the pace on. Between 30-35km they ran an astonishing 13:54 5km. To put into context, the time is just 12 seconds slower than the world record for a 5km parkrun, set by the Irish international runner Nick Griggs. The Doping Question Addressed Naturally there will be questions about whether we can trust Sawe's record, given the chequered history of Kenyans failing doping tests in recent years. It should be noted, however, that before the Berlin marathon in September, Sawe's sponsors, Adidas, paid the Athletics Integrity Unit £50,000 to test him as many times as possible because they wanted to show he was clean. Not only was Sawe tested 25 times in a few weeks, but his samples were also scrutinised with top-end analysis, including isotope ratio mass spectrometry testing, which is much better at detecting tiny levels of banned drugs. The Women's Race Record The women's race turned into a three-way sprint down the Mall, with the Ethiopian Tigst Assefa defending her title after kicking from home in sight of Buckingham Palace. Her time of 2:15:41 was a women's only-word world record, which applies to races with only women's pace makers but is nearly five minutes slower than the official women's world record. In second place, 12 seconds back, was Kenya's Hellen Obiri, while her compatriot Joyciline Jepkosgei finished third. The Future of Marathon Running Sawe's achievement marks a new era in marathon running, pushing the boundaries of what was once considered humanly possible. With advancements in training techniques, equipment technology, and increasingly sophisticated doping detection methods, we can expect more records to fall in the coming years. The two-hour barrier, once thought to be an insurmountable milestone, has now been officially conquered, opening the door for even more ambitious targets in the sport.

The Great Energy Pivot: US Oil and Chinese Solar Dominate Post-Iran Conflict Market

The conflict with Iran has disrupted global energy markets, shifting dominance from the Middle East…
The Global Energy RealignmentIn the open seas, an armada of empty tankers has quietly turned west. A record number of super-sized vessels are now heading to the US, where oil drillers and refineries are preparing to profit from Donald Trump's war in the Middle East. Almost 30 of these vessels, each able to hold 2m barrels of oil, are contracted to load US crude, destined for a global market facing the biggest supply crisis in history.It is just over five years since the shale revolution made the US a net energy exporter and the world's biggest producer of oil and gas. Now the White House is poised to strengthen its claim to an even greater share of the global oil market as the Middle East's decades-long dominance is dismantled by war.US Oil Experiences Unprecedented GrowthThe carriers preparing to amass in US waters are almost six times the monthly number that typically loaded US crude before the war throttled flows of Middle East fossil fuels to the market. Supplies of US crude leaving the country's export terminals have climbed by a third to a record 5.2m barrels a day after Iran retaliated against US-Israeli attacks by blocking daily flows of 10m barrels of Gulf oil exports via the strait of Hormuz.US weekly exports of jet fuel have doubled to an all time high as Europe scrambles to secure supplies and airlines begin to cut flights. The war threatens to reshape the global energy order, exposing the world's reliance on Middle East supplies and accelerating a move towards greener energy, giving rise to new energy superpowers.Latin America Emerges as New Energy PowerhouseThe world's turn to the west marks a potential reordering of global energy supplies, and the greatest threat to the future energy dominance of the Middle East. For decades, Saudi Arabia's vast oil reserves made the kingdom the world's biggest crude supplier and the de facto leader of the Organization of Petroleum Exporting Countries (Opec) cartel and its allies. In a matter of weeks, the Iran war has erased a third of Saudi crude production.Restarting the region's shuttered oil and gas fields and drone-damaged infrastructure is expected to cost between $34bn (£25bn) to $58bn, according to analysts at the consultancy Rystad Energy. The process of restoring production to its previous levels could take years, if it is achieved at all.As doubts over the future market dominance of the Gulf's petrostates deepen, the surge in market prices has begun fuelling the rise of the Americas. The growth in US and Canadian crude production – which has accelerated in recent years – is expected to continue through the 2020s. However, almost half of the world's oil supply growth over the rest of the decade is expected to come from Latin America's oil boom.The Rise of Chinese Solar DominanceThe focus on rerouting fossil fuel flows overlooks another key reordering of the global energy system: the rise of the electrostate. Wood Mackenzie believes the 'out-and-out winner' of the Iran crisis looks likely to be China. While the Middle East conflict has done more than spike oil prices, it has also accelerated global interest in alternative energy sources.China's strategic position in solar energy technology and manufacturing positions it to capitalize on the growing demand for renewable energy alternatives. As traditional oil markets face uncertainty, Chinese solar companies are poised to benefit from the global energy transition.Market Implications and Future OutlookThe rise of the Americas could still be scuppered by a sooner-than-expected reopening of the strait of Hormuz. A full recovery of Gulf oil production could return within a year if the conflict is resolved in the coming months, according to Dylan White, a director at the oil consultancy Wood Mackenzie.Any short-lived increase in oil production from the Americas paled 'in comparison to the volume losses caused by shuttered strait of Hormuz transit,' he added. Yet there is no guarantee that Middle East producers will return to a market and find the same levels of demand.The Iran conflict has fundamentally altered global energy dynamics, creating both immediate winners and long-term structural changes. The US oil industry benefits from short-term market disruptions, while China's solar sector gains from accelerated renewable energy adoption. Meanwhile, Latin American oil producers, particularly Venezuela, stand to gain significant market share as global energy sources diversify away from traditional Middle Eastern dominance.

From Bon Viveur to Alcoholic: Comedian John Robins on His Journey with Addiction

Comedian John Robins, known for his love of alcohol in his comedy, has publicly revealed his diagno…
The Comedian's Journey from Alcohol Enthusiast to SobrietyJohn Robins, the celebrated comedian known for his enthusiastic portrayal of alcohol in his stand-up routines, has publicly revealed his diagnosis as an alcoholic in his new book 'Thirst.' Despite building a career around discussing and celebrating alcohol, Robins has come to terms with his addiction and is now sharing his story of recovery. The Oxford-educated, Edinburgh Comedy Award-winning performer has transformed his personal struggle into a powerful narrative that challenges the glamorous image of drinking culture in comedy.From Childhood Encounters to Full-Blown AddictionRobins' relationship with alcohol began early in life. At just five or six years old, he noticed how champagne made adults relaxed at family celebrations and begged for a sip. By age seven, he had already shown signs of what would become a lifelong obsession: sneaking wine disguised in orange juice from the kitchen. His drinking progressed throughout childhood, with his mother buying him cans of cider at age 12 and him consuming the equivalent of 14 pints at a school party at age 14.At Oxford University, Robins studied English while collecting empty bottles like 'war trophies.' By his early 30s, he had amassed 70 empty bottles of Captain Morgan Dark Rum in his rented flat. Despite his academic achievements and professional success, his focus shifted increasingly to alcohol, with all his attention dedicated to his drinking routine rather than being present at social occasions.The Turning Point: Recognition and RecoveryRobins attempted sobriety multiple times throughout his life, including an 18-month period at age 22 when he started doing stand-up comedy without alcohol. However, each time he returned to drinking heavily. It wasn't until 2023 that he finally found the right word to describe his relationship with alcohol: alcoholic.This realization came during his podcast series 'How Do You Cope?' where he and co-host Elis James discussed how guests had gotten through life's toughest trials. The revelation that the successful comedian had never been able to cope without alcohol marked a turning point in his relationship with himself and his career.Living with Sobriety: Challenges and AcceptanceNow 43 and attending Alcoholics Anonymous, Robins has developed a toolkit to deal with his desire for drink and his past behavior. He acknowledges that alcohol made him controlling, though he takes responsibility for his actions. 'When your focus is on getting the thing you need to survive, you're going to do some unpleasant stuff to get there,' he explains.Robins has learned to exist in a world with alcohol without being triggered by reminders of his past. While some recovering alcoholics might remove all references to booze from their homes, Robins takes a different approach: 'I have to exist in a world with alcohol in it, and I can make that really difficult or I can make that as easy as it's ever going to be.'The Power of Thirst: A New ChapterRobins' new book, 'Thirst,' takes its title from the core of his relationship with alcohol throughout his life. The publisher initially wanted the subtitle 'Twelve Drinks That Changed My Life' for its marketability, but Robins insisted on the more powerful 'Thirst.' The book's cover features a shocking image of a young boy clutching a can of lager, symbolizing Robins' lifelong relationship with alcohol.Following his stand-up show 'Howl' about his addiction, 'Thirst' represents another step in Robins' journey of sharing his story. The comedian has transformed his personal struggle into a narrative that not only addresses his own recovery but also challenges the culture of alcohol consumption in the comedy industry and beyond.The Future of Recovery and Public DiscourseRobins' public acknowledgment of his alcoholism comes at a time when conversations about mental health and addiction are increasingly entering mainstream discourse. By sharing his story as a successful comedian, he brings a unique perspective to the discussion, highlighting how addiction can affect even those who appear to have it all.As Robins continues his recovery, his journey offers hope to others struggling with similar issues. His approach—acknowledging the past without being defined by it, learning to coexist with triggers, and taking responsibility for his actions—provides a roadmap for sustainable recovery. In a world that often glorifies drinking culture, Robins' story stands as a powerful counter-narrative of honesty, vulnerability, and transformation.

UK Government Departments Clash Over AI Datacentre Energy Demands

UK government departments are at odds over the energy demands of AI datacentres, with DSIT projecti…
The Government's Energy Calculations ClashThe UK government is facing internal divisions over the energy demands of AI datacentres, with two key departments offering vastly different projections. While the Department of Science, Innovation and Technology (DSIT) forecasts that AI datacentres will consume 6GW of electricity by 2030, the Department of Energy Security and Net Zero (DESNZ) projects usage of less than a tenth of that amount. This discrepancy raises questions about how the UK can simultaneously pursue its ambition to become an AI superpower while meeting decarbonization targets.Conflicting Projections from Key DepartmentsThe DSIT's "UK compute roadmap," published in 2025, sets out a "bold, long-term plan to transform our national compute ecosystem" by building AI datacentres. The document explicitly states: "We forecast that the UK will need at least 6GW of AI-capable datacentre capacity by 2030." This ambitious plan involves creating multiple AI growth zones across the country, each requiring at least 500MW of electricity.In contrast, DESNZ, which is responsible for the UK's carbon budget and climate targets, has incorporated AI datacentres into broader forecasts for the energy use of Britain's "commercial services" sector. These projections suggest the entire sector's energy use will grow by just 528MW between 2025 and 2030 – equivalent to adding the consumption of 1.7m homes by the end of the decade.The DESNZ has stated it does not hold separate projections for datacentre growth, despite the government's commitment to building significant AI infrastructure.The Scale of the DiscrepancyThe difference between the departments' projections is staggering. DSIT's estimate of 6GW for AI datacentres alone is more than ten times higher than DESNZ's projection for the entire commercial services sector's growth. This means that if DSIT's projections are accurate, the energy demands of AI datacentres would far outpace the government's current plans for grid expansion and decarbonization.Each proposed AI growth zone would require at least 500MW of electricity – an amount only slightly less than DESNZ's forecast for the increase in energy usage of the entire commercial services sector. This suggests that even a handful of these zones would strain the government's energy planning.Revised Emissions Figures and ControversyThe controversy surrounding these projections deepened when DSIT revised its figures for the carbon emissions of AI datacentres. Originally, DSIT's projections for the carbon emissions of additional AI computing capacity were between 0.025m and 0.142m tonnes of carbon equivalent (MtCO₂) – below 0.05% of Britain's projected emissions.After questions were raised about the plausibility of these figures, the document containing them was removed from the government website. Then, after inquiries from The Guardian, DSIT updated its numbers significantly. In a statement posted online, the department acknowledged: "The UK's cumulative 10-year greenhouse gas emissions from AI compute could range from 34 to 123 MtCO₂ – this is around 0.9-3.4% of the UK's projected total emissions over the 10-year period."This represents more than a hundredfold increase in the estimated emissions, raising serious questions about the initial calculations and the transparency of the government's planning process.Critics Question Government Competence and Corporate InfluenceThe conflicting projections have drawn sharp criticism from experts and observers. Tim Squirrell, the head of strategy for the NGO Foxglove, commented: "The government's cluelessness over the environmental impact of datacentres would be laughable, if it weren't so alarming."Cecilia Rikap, a researcher at University College London, offered two possible interpretations of the "misalignment": either DESNZ and DSIT are incompetent, or there's some kind of "magical thinking about AI and big tech." She added: "Either way, the episode uncovers how these corporations control not only the AI value chain, but also the UK government."Foxglove filed an environmental impact assessment request with DESNZ in January, asking how the department had incorporated AI datacentres into its projections for Britain's emissions. The response, which referred to broader forecasts for the commercial services sector, did not address the specific concerns raised.Future of UK AI Strategy and Climate GoalsThe UK government appears to be attempting to balance competing priorities: becoming a leader in artificial intelligence while meeting international climate commitments. Carbon budget 7, which will outline the UK's climate plans for the coming years, is set to be released this summer and may provide more clarity on how these objectives will be reconciled.A spokesperson for DESNZ noted that "datacentre emissions are factored into our modeling, including for carbon budget 7," and mentioned that "The AI Energy Council is exploring opportunities to attract investment and support the development of clean power for datacentres."However, the significant discrepancy between government departments suggests that the UK's strategy for becoming an AI superpower may be developed without adequate consideration of its environmental implications. As the government moves forward with its AI ambitions, the tension between technological advancement and climate responsibility will likely remain a central challenge.
