AI boom means US is now ‘investing more’ in fossil-fuel power than China
The rapid expansion of artificial intelligence (AI) technologies in the United States is driving a significant increase in investment in fossil-fuel power, particularly natural gas. This surge is largely attributed to the growing demand for data centers, which require substantial and reliable electricity supplies. As a result, the US is now investing more in fossil-fuel power infrastructure than China, marking a notable shift in global energy investment patterns. This trend highlights the complex relationship between technological advancement and energy consumption. Data centers, essential for AI development and cloud computing, are energy-intensive facilities that often rely on natural gas plants for consistent power. Despite ongoing efforts to transition to renewable energy sources, the immediate need for stable electricity to support AI growth has led to increased fossil fuel investments. This development raises concerns about the environmental impact of the AI boom, as it may slow progress toward decarbonization goals. The US’s increased fossil fuel investment contrasts with its historical role as the world’s largest carbon emitter and its recent climate policy shifts. Under previous administrations, coal use declined significantly, but the current focus on natural gas reflects a pragmatic approach to balancing energy reliability and emissions reductions. Meanwhile, China, traditionally the largest investor in fossil fuel power, is seeing its relative share decrease as the US ramps up spending to meet AI-driven energy demands. This dynamic underscores the challenges of aligning technological innovation with climate commitments. While AI promises economic growth and efficiency gains, its energy footprint could complicate efforts to reduce greenhouse gas emissions. Policymakers and industry leaders face mounting pressure to find sustainable solutions that support AI infrastructure without exacerbating climate change.
‘It’s an obsession’: one man and his family on a mission to save Europe’s glutinous snail
Ian Hughes and his family are spearheading efforts to save the glutinous snail, one of Europe’s most endangered molluscs, found only in the freshwater habitat of Llyn Tegid (Bala Lake) in north Wales. The snail, notable for its delicate, gelatinous shell, has been driven to extinction in much of England due to pollution from agriculture and industry. Hughes, who has devoted over a decade to conserving this tiny species, often works alongside his sons, using careful scientific methods to protect and monitor the snails in their last remaining UK habitat. The glutinous snail’s fragile shell requires meticulous handling, with Hughes using fine paintbrushes to move the creatures without harm. The species’ decline reflects broader environmental challenges facing freshwater ecosystems, where pollutants have severely damaged habitats such as ponds, ditches, and lakes. This year, the UK government’s Department for Environment, Food and Rural Affairs (Defra) recognized the snail’s critical status by including it in a £60 million funding initiative aimed at protecting threatened species, providing a significant boost to conservation efforts. Hughes’s passion for wildlife conservation began in his youth, initially through art and taxidermy, before transitioning into invertebrate care and environmental projects supported by Natural England. His family has been integral to his work, with his sons regularly accompanying him on field trips, often involving physically demanding tasks like wading into cold waters to collect samples and monitor populations. This family-driven approach underscores the personal commitment behind the scientific mission to preserve the glutinous snail and highlights the importance of grassroots conservation efforts in safeguarding biodiversity. The plight of the glutinous snail serves as a stark reminder of the vulnerability of freshwater species to human-induced environmental changes. Protecting such rare organisms not only preserves unique elements of Europe’s natural heritage but also signals broader ecosystem health, emphasizing the need for continued vigilance and investment in habitat restoration and pollution control.
Weather tracker: deadly May heatwave shatters records across Europe
Europe has experienced an intense and unprecedented heatwave this May, with several countries breaking long-standing temperature records. The UK recorded its highest May temperature ever at 35.1°C in Kew Gardens, London, surpassing the previous day’s record of 34.8°C. France also saw record-breaking highs, reaching 36°C on consecutive days. Ireland reported its warmest May temperatures on record, with 28.8°C measured in Killarney and Clonmel. Night-time temperatures remained unusually high as well, with Camborne in south-west England experiencing a tropical night at 21.4°C. This extreme heat is attributed to a persistent “heat dome,” a high-pressure system causing temperatures to soar 10-15°C above average for this time of year. The heatwave has had serious consequences, including at least seven deaths in France linked directly or indirectly to the soaring temperatures. Although temperatures are expected to remain elevated through the week, forecasts suggest a gradual moderation in the UK by next week. The event highlights growing concerns about the frequency and severity of heatwaves in Europe amid climate change. Meanwhile, severe weather contrasts the heatwave in parts of the Southern Hemisphere, with eastern Australia facing intense thunderstorms and flash flood warnings. The Bureau of Meteorology has issued alerts for damaging winds, heavy rainfall, and hail, particularly affecting Queensland and New South Wales. Some areas have already recorded significant rainfall and strong wind gusts, with potential for localized totals of up to 100mm. These contrasting weather extremes underscore the increasing volatility and intensity of global weather patterns.
Pacific Islanders slowly recover from the strongest storm of the year
Typhoon Sinlaku, the strongest storm to hit the Western Pacific this year, struck the Commonwealth of the Northern Mariana Islands (CNMI) on April 14, leaving widespread devastation and a lingering recovery effort. The typhoon rapidly intensified to 185 mph before weakening slightly to 150 mph as it made landfall on Saipan, the largest island in CNMI. Residents like Katelynn Delos Reyes, a lifelong Chamorro resident, faced unprecedented destruction despite previous experience with major storms such as Supertyphoon Yutu and Typhoon Soudelor. Sinlaku’s powerful winds and heavy rains caused severe damage to homes, infrastructure, and the local environment, forcing tens of thousands to shelter for days amid ongoing threats. More than a month after the storm, communities across the Northern Mariana Islands and neighboring regions continue to struggle with power outages, debris removal, and rebuilding efforts. The tourism district of Garapan remains littered with wreckage, highlighting the storm’s impact on the local economy. Sinlaku has resulted in at least 17 confirmed deaths across the Micronesian region, making it the deadliest storm there since 2002. Fatalities include a couple on Guam who died from carbon monoxide poisoning due to indoor generator use and six crew members of the cargo ship Mariana, which lost engine power during the storm. In Chuuk State, Federated States of Micronesia, nine people died, including a baby whose pregnant mother was unable to reach medical care because of blocked roads. The storm’s rapid intensification and prolonged presence over the region underscore the increasing volatility of Pacific typhoons amid changing climate patterns. Sinlaku’s impact has exposed vulnerabilities in infrastructure and emergency preparedness across island communities, emphasizing the need for enhanced resilience measures. As recovery efforts continue, residents face the dual challenges of restoring normalcy and preparing for future storms in a region frequently battered by extreme weather events.
Ask a Climate Therapist: Is it still ‘catastrophizing’ if the threat is real?
Therapist Leslie Davenport addresses the challenge of managing anxiety in the context of the escalating climate crisis, emphasizing that what might once have been labeled as catastrophic thinking is now often a realistic response to genuine threats. Traditional therapeutic approaches that focus on recalibrating distorted thoughts toward “what’s realistic” may no longer apply when the reality itself is dire and worsening. Instead, Davenport suggests shifting the therapeutic goal from seeking an accurate assessment of the crisis to achieving “functional clarity” — understanding the situation well enough to take meaningful action. Davenport highlights the human tendency toward negativity bias, which amplifies perceptions of threat and can be exacerbated by constant exposure to alarming news, a phenomenon known as doomscrolling. This bias, while evolutionarily adaptive, can distort one’s emotional response and lead to overwhelming despair. To counterbalance this, she recommends actively seeking out positive developments in climate action, such as renewable energy growth, legal victories by youth activists, and community resilience efforts. These stories, though less prominent in mainstream media, can provide hope and motivation. The therapist underscores that acknowledging progress does not lessen the urgency of the climate crisis, which continues to outpace solutions. The emotional toll of witnessing ongoing environmental degradation and insufficient systemic change can be intense. Therefore, therapy should focus on helping individuals channel their anxiety into constructive engagement, whether through activism, policy advocacy, or personal lifestyle changes. This approach aims to transform distress into empowerment, fostering resilience amid uncertainty rather than attempting to minimize legitimate fears. Davenport’s insights reflect a broader shift in mental health care as it adapts to the realities of climate change, recognizing that anxiety about the environment is not a symptom of distorted thinking but a valid response to a complex global emergency. Her guidance offers a framework for maintaining psychological well-being while confronting one of the most pressing challenges of our time.
Global heating is making hajj ever more dangerous, report finds
Global heating has significantly increased the risks faced by millions of Muslim pilgrims during the annual hajj in Mecca, Saudi Arabia, according to new research. Rising temperatures, driven by carbon dioxide emissions from fossil fuels, have caused scorching heat of 40°C (104°F) to become common as early as May, a month that was historically cooler. This shift means that dangerous heat conditions, once confined to the summer months, are now expected almost year-round during the pilgrimage, which involves walking long distances over five days in the open air. The study highlights that the average temperature in May has risen by 3.5°C due to human-caused global warming, making hajj in this month as perilous as the peak summer used to be. In 2024, when hajj took place in June, more than 1,300 pilgrims died from extreme heat and humidity. The Islamic lunar calendar causes the timing of hajj to move earlier each year, exposing pilgrims to increasingly hazardous weather conditions. Saudi Arabia, the world’s second-largest oil producer, plays a central role in this crisis, as its fossil fuel industry contributes heavily to global emissions and has historically resisted climate action. In response to the escalating heat risks, Saudi authorities have implemented heat action plans including shaded walkways, cooling stations, misting systems, and expanded medical services to mitigate heat-related illnesses among pilgrims. However, experts warn that these measures are insufficient without a rapid global transition away from fossil fuels. Researchers from Imperial College London emphasize that without significant reductions in carbon emissions, millions of Muslims will be forced to perform hajj in a climate that is increasingly unsuitable and dangerous. The findings underscore the broader implications of climate change on religious and cultural practices, highlighting the urgent need for coordinated international efforts to address fossil fuel dependence. As global temperatures continue to rise, safeguarding the health and safety of pilgrims during hajj will require both local adaptation strategies and global climate mitigation policies.
Should I get air conditioning in the UK – and can it be green?
As the UK experiences increasingly hotter summers, the number of homes with air conditioning has doubled to around 4 million in the past three years. Many British homes, not originally designed for extreme heat, are turning to portable air conditioners and air-to-air heat pumps to manage rising indoor temperatures. However, concerns about the environmental impact of these energy-intensive devices persist, especially as some larger systems can consume more power than household ovens. Experts warn that widespread use of air conditioning could hinder the UK’s progress toward net zero carbon emissions. The government’s climate advisers estimate that about 22% of British homes may require active cooling with 2°C of global warming. Researchers like Nicole Miranda from the University of Oxford emphasize the importance of using air conditioning judiciously and pairing it with renewable energy sources, such as solar panels, to reduce carbon footprints. Homeowners like Jon Connorton in Hampshire exemplify this approach by running portable units only when solar power is available. To mitigate environmental concerns, alternative cooling strategies are gaining attention. Green roofs and improved building insulation can help maintain cooler indoor temperatures without heavy reliance on air conditioning. Additionally, timing the use of air conditioners to coincide with periods of high renewable energy supply on the national grid can further reduce emissions. While air conditioning offers relief during heatwaves, balancing comfort with sustainability remains a key challenge for UK households adapting to a warming climate.
Why temperature records are being not only broken but smashed
Western Europe is experiencing an unprecedented early-season heatwave, with hundreds of temperature records shattered across multiple countries. The UK recorded temperatures exceeding 35°C in May, surpassing previous records by more than 2°C, while France, Ireland, Germany, Italy, Spain, and Switzerland have also faced unusually high spring temperatures. The extreme heat is attributed to a persistent "heat dome" of high pressure trapping warm air over the region, intensifying the conditions. Scientists emphasize that this heatwave is not just a natural anomaly but is significantly amplified by human-induced climate change. Over the past three decades, Europe’s average temperature has risen by 0.56°C per decade, more than twice the global average, making heat extremes more severe and frequent. Experts note that while heatwaves were predicted as a consequence of global warming, the intensity and early arrival of these records are surpassing earlier expectations. This pattern aligns with broader global trends, as other regions, including parts of India, are also experiencing record-breaking temperatures. The breaking and surpassing of temperature records at such a scale is unusual in a stable climate, where new extremes typically become less frequent over time. However, the ongoing warming trend means that new records are not only more common but are being "smashed" by significant margins. This phenomenon underscores the accelerating impact of climate change on weather patterns, highlighting the urgent need for mitigation and adaptation strategies to manage the increasing risks posed by extreme heat events.
Nasa unveils next steps to build permanent Moon base
Nasa has outlined its next steps toward establishing a permanent Moon base, focusing on deploying robotic landers, hopping drones, and delivery vehicles to the lunar surface. The agency has awarded contracts to companies including Blue Origin, Intuitive Machines, and Astrobotic to develop these machines, which will explore and map the Moon’s terrain ahead of human missions. The goal is to return Americans to the Moon before 2029 and build a sustainable base near the lunar South Pole by 2032, enabling scientific research, resource mining, and future Mars missions. The initial phase of Nasa’s Ignition Moon Base programme involves sending robotic explorers to conduct detailed surveys and deliver scientific instruments such as high-resolution cameras and laser-based landing aids. Blue Origin’s Endurance lander will feature precise landing capabilities and autonomous navigation, while Astrobotic’s Griffin-1 lander is slated to touch down at Nobile Crater. Over the next several years, Nasa plans approximately 25 launches to deliver around four metric tonnes of cargo to the Moon, laying the groundwork for human habitation. Nasa’s ambitions come amid intensifying competition with China, which aims to land astronauts on the Moon by 2030 and recently launched its Shenzhou-23 crew to the Tiangong space station. Experts express skepticism about Nasa’s aggressive timeline, citing challenges in developing human-rated lunar landers and China’s rapid progress in space exploration. Some scientists believe China may be the first to return humans to the lunar surface after the Apollo era. Looking ahead, Nasa intends to establish nuclear and solar power systems on the Moon, including fission reactors, to support long-term operations. The permanent base is envisioned as a strategic platform for advancing lunar science, exploiting resources, and serving as a stepping stone for crewed missions to Mars, reinforcing the United States’ commitment to maintaining a leading role in space exploration.
