DEDURU OYA, Sri Lanka – On April 16, eight members of Priyantha Kumara’s family including his wife, son, brother, father-in-law, and four other relatives were swept away by strong currents in the Deduru Oya, a river in Sri Lanka’s North Western province. Sri Lanka Police reported more than 30 drowning deaths between April 12 and 21 this year, underscoring the risks posed by flooding rivers. Sri Lanka Police media spokesperson Udaya Kumara Wootler told Mongabay that 376 individuals have died due to drowning in rivers last year while 595 fatalities were reported in 2024. Buddhika Sampath, spokesperson for the Sri Lanka Navy told Mongabay that the Navy Diving Unit recovered 148 bodies of people between May 2022 and May 2023. While the police are yet to disclose official statistics of deaths due to drowning from January to May 2026, the number of reported incidents show over 50 fatalities. Kumara is a resident of Gopallawa in the northwestern district of Kurunegala. His son had requested that they all go for a bath in the river. The group had been bathing at a popular spot named Kuriyagas Mankada when they met the tragedy. “My son was only 13 years old, and he was a bright student,” Kumara told Mongabay. “My brother was about to hold a housewarming ceremony at his newly built house. But all these dreams were shattered within seconds. My father used to take us to this same spot to bathe when we were young. But the river has changed…This article was originally published on Mongabay
California could be due for a major earthquake in the near future, according to concerning new models based on data comprising 1,000 years of quake activity on the West Coast.
According to recent findings, tectonic stress has quietly been building in California to levels not seen since the last major earthquake in the region, which bore a magnitude of 7.9 and struck the West Coast nearly 170 years ago.
That event, known as the Fort Tejon earthquake, affected the greater Los Angeles area, and since the time of those historic rumblings, researchers have grown increasingly concerned about a period of seismic silence that could point to the likelihood of an event of similar magnitude at some point in the future.
The potentially concerning new forecast was detailed in a recent study by an international team of researchers led by Dr. Liliane Burkhard of the Division of Space Research and Planetary Sciences (WP) at the Physics Institute of the University of Bern, which focused on historic earthquake data as a means of gauging current stress loading at Cajon Pass.
The study, published in the Journal ofGeophysical Research: Solid Earth, indicates tectonic stress levels that are now believed to exceed the highest seen during the years the team surveyed.
The “Earthquake Gate” at Cajon Pass
The researchers aimed to investigate stress that has slowly built along the San Andreas and San Jacinto faults and incorporated what they likened to an “earthquake gate” at Cajon Pass, which, in their models, functioned like a point of control that governed the size of earthquakes and whether they could spread to both systems.
For their research, they used a four-dimensional earthquake cycle model that allowed them to replicate certain processes both in spatial dimensions and across time.
Using a millennium of reconstructed earthquake data from the region based on geological information such as radiocarbon dates, unusual events recorded in dendrochronological data (i.e., information obtained from tree rings), and historical information sources, the team gave this to the model they devised.
Dr. Burkhard said the team’s simulation offered them a unique opportunity to better understand the ways stresses in the fault system build up over long periods of several centuries.
“By running the earthquake history of Southern California as a simulation, we can estimate the extent to which the fault system is already under stress today,” Dr. Burkhard said. The results of those simulations weren’t particularly promising either: according to Burkhard, current stress levels in the region are the highest they have been in 1,000 years, based on the data.
Concerning New Earthquake Data
The team also identified significant new information regarding the function of the so-called “earthquake gate” at Cajon Pass.
“The earthquake gate concept captures something important about how fault junctions work,” Burkhard said in a recent statement. “Cajon Pass doesn’t simply block or channel earthquakes: It responds to stress conditions, and those conditions change over centuries.”
Not only this, but Burkhard and her team also determined that a key element to these quakes involves not only the level of stress that accumulates at a single fault, but perhaps more significantly, the way stress between two systems can align. This is because, as the stress across a pair of faults rises together over longer periods, this appears to be most conducive to a large joint rupture comparable to the 1857 Fort Tejon earthquake.
Conversely, if stress levels are not in concert as they evolve, the team determined that this causes quakes that probably will not propagate beyond the junction.
In short, a more severe earthquake event today would entail a joint rupture that crosses the Cajon Pass, as opposed to one constrained either to the San Andreas or the San Jacinto Fault alone. Should such an event occur, it would likely impact one of the largest population centers, as well as a crucial infrastructure system that supplies energy and transportation to surrounding areas.
For Burkhard, “The question of when and how the next major earthquake will occur in this region is one of the most pressing problems in applied geoscience.” Based on the team’s findings, they say that their new modeling hopes to provide a much more complete picture of the science behind the factors that could lead to a major quake—conditions that could apply equally to other parts of the world as they do to California.
Burkhard adds that her team’s study is not intended merely as a prediction for when the next major earthquake could potentially occur, but also as a means of preparing for future quakes and mitigating their effects.
“What we can say is that the system is critically stressed and that physics-based models like ours give a clearer picture of the range of scenarios we should be prepared for,” Burkhard says. “This information is important for hazard assessment, infrastructure planning, and emergency preparedness.”

Across the stories today, a common thread emerges: the growing gap between urgent environmental realities and the systems—political, economic, and social—struggling to keep pace with change.
This tension plays out most starkly in the realm of climate health impacts. New research warns that heat-related hospitalizations could double by 2040, while a super El Niño threatens to deepen global economic inequality through cascading climate disruptions. Behind the numbers are real communities adapting in real time. In Pacoima, a working-class Los Angeles neighborhood sandwiched between highways and heavy industry, residents like Jose Luis Salas are mounting their own defense against air pollution, installing shoebox-sized monitoring devices that track what they breathe daily.
Yet the day’s coverage also points to growing momentum around practical solutions gaining real traction. Solar energy quietly surpassed coal in U.S. electricity generation for the first time this May—a milestone that arrived not through grand announcements but through the steady accumulation of rooftop panels and utility-scale installations. Britain cleared a major bottleneck by offering grid connections to over 700 clean energy projects, while new data reveals the country’s green economy now employs over one million workers across a £100 billion sector.
The stories reveal how environmental challenges are increasingly driving innovation at the community level. In Guatemala’s Western Highlands, approximately 60 communities are reviving ancient Maya agricultural wisdom, creating homemade biopesticides from aromatic plants to replace expensive chemical alternatives. Similarly, 120 women farmers in Malawi’s Chiradzulu district have transformed traditional maize cultivation by adding organic fruits and vegetables now in high demand from urban buyers—though their success is shadowed by a troubling reality: their bees, crucial pollinators for food security, are mysteriously disappearing.
It’s a reminder that progress and pressure often arrive together. Colombia enacted groundbreaking legislation requiring detailed cattle tracking to prevent deforestation-linked beef from reaching markets, while Indonesia’s magnificent hornbills face accelerating threats from both habitat loss and an illegal online pet trade. The contrast illustrates how conservation gains in one area can be undermined by emerging threats in another.
Perhaps most telling is how wealth continues to complicate climate action. New research from Greenpeace reveals that the ultra-rich drive a quarter of global emissions not through private jets—their visible symbols of excess—but through their investment portfolios and asset ownership. Meanwhile, chemical companies are quietly pushing “immunity laws” across 15 states to shield themselves from health-related lawsuits, even as communities bear the costs of environmental damage.
The space program offers its own metaphor for these broader tensions. NASA’s latest astronaut selections for Artemis missions reflect both ambition and limitation—crews training for missions that won’t reach the Moon, while hundreds of women gathered at the AeroWomen conference to prepare for space careers in an industry still taking shape.
As the week unfolds, all eyes will be on whether these parallel tracks—accelerating environmental pressures and emerging solutions—can converge into the systemic changes scientists say are necessary. Today’s stories suggest we’re living through a period when local innovation and global challenges are both intensifying, creating opportunities for breakthrough and breakdown in equal measure.
US energy secretary Chris Wright featured in seminars to judges when he was a fracking executive
As cities and states sue big oil for billions in damages over allegations that it covered up the dangers of its products, rightwing organizations are attempting to discredit the wave of litigation. They claim the lawyers behind it are teaming up with an environmentally focused legal education non-profit to bias federal judges against oil companies.
But it is actually fossil fuel-backed organizations that are attempting to sway the judiciary in their favor, one of those law firms is countering. Evidence of this includes judicial seminars hosted by one such group featuring pro-industry speakers such as the current energy secretary, Chris Wright, in his former occupation as a fracking executive.
A powerful El Niño weather pattern is emerging as a formidable force that could significantly worsen existing economic disparities across the globe. This climate phenomenon, characterized by unusually warm ocean temperatures in the Pacific, has the potential to trigger a cascade of environmental and economic disruptions that will disproportionately affect the world’s most vulnerable populations.
The intensifying El Niño brings with it a familiar yet devastating playbook of climate impacts: prolonged droughts in some regions, catastrophic flooding in others, and widespread agricultural disruption that threatens food security worldwide. These weather extremes don’t affect all nations equally—developing countries with limited infrastructure and financial resources often bear the heaviest burden when crops fail, supply chains collapse, and communities are forced to rebuild from climate disasters.
Economic experts warn that this “super” El Niño could amplify existing inequalities between wealthy and developing nations. While affluent countries have greater capacity to adapt and recover from climate shocks through advanced technology, robust insurance systems, and emergency reserves, poorer nations often struggle to protect their populations and economies from the same environmental threats. The result is a widening gap where climate change becomes both a symptom and a driver of global economic inequality, creating a vicious cycle that leaves the most vulnerable populations increasingly exposed to future climate risks.
Americans are bracing for another summer of dangerous heat waves, and new research suggests the health crisis is only getting worse. A groundbreaking study projects that heat-related hospitalizations across the United States could double over the next 15 years, creating an unprecedented strain on the nation’s healthcare system.
The alarming findings predict annual heat-related emergency department visits and hospitalizations will surge from approximately 109,000 cases today to as many as 237,000 cases by 2040. This dramatic increase reflects the growing intensity and frequency of extreme heat events driven by climate change, which are pushing human bodies beyond their ability to cope safely.
The healthcare implications extend far beyond patient suffering. This spike in heat-related medical emergencies is expected to drive annual healthcare costs for heat-related conditions above $1 billion, placing enormous financial pressure on hospitals, insurance systems, and families already struggling with rising medical expenses.
The study’s authors describe the current state of preparedness as “woeful,” highlighting a critical gap between the escalating threat and existing public health infrastructure. Heat-related illnesses disproportionately affect vulnerable populations including elderly residents, outdoor workers, and communities with limited access to air conditioning or cooling centers. As extreme temperatures become the new normal rather than exceptional events, public health officials are calling for urgent investments in heat adaptation strategies, improved early warning systems, and expanded cooling resources to protect lives in the coming decades.
In Pacoima, a working-class neighborhood trapped between Los Angeles highways and heavy industry, residents are taking air quality monitoring into their own hands. Jose Luis Salas recently watched as environmental project manager Shance Taylor climbed a ladder to install a shoebox-sized white container on the side of his home—an Aeroqual sensor that’s part of an ambitious community-led air monitoring program.
The sensor network, operated by local environmental group Pacoima Beautiful, represents a growing trend of hyperlocal air quality monitoring that gives communities real-time data about the pollution they’re breathing. Unlike traditional government monitoring stations that may be miles away, these sensors provide block-by-block information about air quality conditions.
Pacoima’s geography makes it particularly vulnerable to poor air quality. Nestled in Los Angeles’s northeast San Fernando Valley, the neighborhood sits at the intersection of major freeways and industrial facilities, creating a perfect storm for air pollution accumulation. Residents often report higher rates of asthma and respiratory issues compared to other parts of the city.
The grassroots monitoring program empowers residents with data they can use to make informed decisions about outdoor activities, advocate for policy changes, and hold polluting industries accountable. By installing sensors on homes, offices, and even portable units carried in bags, the community is creating an unprecedented picture of how air pollution varies throughout their neighborhood—data that could prove crucial for protecting public health and environmental justice.
A powerful 6.1-magnitude earthquake struck the Caribbean waters off Cuba’s coast Monday afternoon, marking the strongest seismic event the region has experienced in nearly 150 years. The significant tremor sent shockwaves far beyond its epicenter, with residents across Florida and parts of Mexico, including the popular resort destination of Cancún, reporting feeling the ground shake.
The earthquake occurred approximately 65 miles northwest of Mantua, Cuba, at a depth of 16 miles beneath the ocean floor, according to the US Geological Survey. This relatively shallow depth likely contributed to the widespread sensation of the tremor across multiple countries and hundreds of miles from the epicenter.
The Caribbean region sits within a complex zone of tectonic activity, where several major fault systems intersect. While earthquakes of this magnitude are rare in the area, the event serves as a reminder of the ongoing geological processes that shape the region’s landscape and coastal environments. The shallow marine location of this earthquake highlights the dynamic nature of the seafloor in the Caribbean basin.
Scientists continue to monitor the area for potential aftershocks, which commonly follow significant seismic events. The widespread reach of Monday’s earthquake—felt across international borders and vast distances—demonstrates how major geological events can impact entire regional ecosystems and coastal communities simultaneously, underscoring the interconnected nature of Caribbean environmental systems.
The net zero economy is booming, so claims that prosperity depends on oil and gas are bunkum – unless you’re a Reform backer with fossil fuel interests, of course
Really? You want to destroy a million jobs? Vote Reform UK for mass unemployment: is that your pitch? Hammer these questions home whenever you meet a supporter of the party. Or, for that matter, a Conservative, as their party now takes an almost identical line.
The figures are stark. They were compiled not by Just Stop Oil or the Green party, but by that bastion of conservatism, the Confederation of British Industry. They show that the net zero economy now directly employs more than 300,000 full-time workers, while supporting the jobs of 1.1 million. The net zero sector is worth £100bn to the UK already, and is likely to grow by hundreds of billions more. The rest of the green economy directly employs a further 600,000.
The 700 projects include wind and solar farms, battery storage, gas and hydro plans
More than half the renewable energy projects needed to meet the government’s clean power targets by 2030 are now able to plug into the electricity grid after years of delay, according to the system operator.
The National Energy System Operator (Neso) has offered more than 700 clean energy projects in Great Britain a grid connection date since the start of the year, after a two-year process to unblock a bottleneck that threatened to delay projects into the 2030s.
Government plan to de-link gas and electricity prices aims to reduce bills for consumers after global surge in prices
Households in England, Scotland and Wales could save nearly £200 a year on their energy bills if the government stepped into the market to act as the sole buyer of electricity, according to a thinktank.
The research found that public procurement of electricity, meaning the government would become the “single buyer” of power before it is resold to consumers, could shave billions of pounds from electricity prices.
The global space industry is expanding rapidly, with thousands of new satellites expected to enter orbit in the coming years. These spacecraft will support a wide range of activities, including internet services, Earth observation, scientific research, and even space tourism. While this growth promises many benefits, scientists are becoming increasingly concerned about its environmental impact. […]
Across the stories today, a common thread emerges: the growing tension between our rapidly expanding digital world and the natural systems struggling to sustain it. From AI data centers planned for drought-stricken regions to coal plants getting emergency extensions, we’re witnessing the collision between technological acceleration and environmental limits.
The numbers tell a stark story. Two-thirds of new AI data centers are slated for areas already grappling with water scarcity, while these facilities demand massive amounts of both electricity and cooling water. Meanwhile, Florida’s coal plant—scheduled for retirement as part of a clean energy transition—gets an emergency lifeline to keep the lights on. It’s a reminder that progress and pressure often arrive together, forcing difficult choices between immediate needs and long-term sustainability.
The day’s coverage points to growing momentum around accountability, particularly in how we fund and regulate resource-intensive industries. Australian lawmakers are pushing for fair taxation of AI infrastructure, determined not to repeat what they see as mistakes with gas exports. North Carolina legislators face their own paradox, crafting bills that simultaneously curb data center expansion while boosting fossil fuel development. These policy tensions reflect a broader reckoning: how do we harness technological progress without overwhelming the ecosystems that support us?
Yet signs of genuine environmental recovery punctuate today’s more challenging headlines. Water voles have returned to an English nature reserve after four decades, while marine protected areas now cover 10% of the world’s oceans—a significant milestone toward the 30% goal by 2030. In Sumatra’s hills, coffee farmers like Sri Atmiatun are proving that conservation and community prosperity can grow together, restoring forests while securing livelihoods through innovative social forestry programs.
Behind the numbers are real communities adapting in real time. Alaska’s fishing industry faces uncertainty as critical ocean monitoring systems face budget cuts, while Arizona’s San Carlos Lake sits closed indefinitely after drought and dam releases killed all fish life. These aren’t abstract environmental statistics—they’re disruptions to ways of life, forcing entire communities to reimagine their relationships with changing landscapes.
The financial flows reveal where power and priorities truly lie. The world’s largest banks poured a record $906 billion into fossil fuels despite climate commitments, an 8% increase that environmental researchers call “unfathomable.” Meanwhile, China launched the world’s first wind-powered underwater data center, signaling that sustainable technology infrastructure is possible when political will aligns with innovation.
Perhaps most troubling is what we’re losing while focused on these larger battles. Wildfire smoke has erased four years of air quality progress across the United States, while sea levels are now rising at twice the rate recorded just a decade ago. Scientists are racing to record forest sounds before wild spaces fall silent—a poignant reminder that some losses can’t be reversed.
The day’s stories also illuminate the gap between good intentions and effective action. Louisiana legislators unanimously approved expanding their wood pellet industry despite the bill’s sponsor admitting he knows little about the sector. FIFA appears unprepared for wildfire smoke threats at upcoming World Cup venues. These moments reveal how quickly environmental challenges can outpace institutional readiness.
As the week unfolds, all eyes will be on whether emerging solutions—from underwater data centers to marine protection expansions—can scale fast enough to match the magnitude of the challenges. The central question remains: can we innovate our way toward sustainability, or will the pace of environmental change force more fundamental reckonings with how we live and build in a resource-constrained world?
During a survey of Kastellorizo in the Dodecanese, researchers found a previously unknown cave cricket inhabiting an artificial underground passage on Mount Vigla. The species, described in the Journal of Orthoptera Research, is part of the genus Dolichopoda. These cave-dwelling crickets occur throughout southern Europe and the eastern Mediterranean, and often form distinct species when populations become isolated in separate underground habitats.
These cave-dwelling crickets throughout southern Europe and the eastern Mediterranean and often form distinct species when populations become isolated in separate underground habitats.
The team named the species Dolichopoda balrogi after the Balrog, the ancient fire-demon who resided beneath the mountains in the Mines of Moria in J.R.R. Tolkien’s The Lord of the Rings. In Tolkien’s story, the Balrog remained hidden underground until disturbed by the Dwarves.
An Island With No Caves
Kastellorizo covers about nine square kilometers, making it one of the smallest inhabited islands in Greece. The island is actually located closer to the Turkish coast than to the Greek mainland. The landscape also lacks any accessible natural caves. The only underground environment available for survey was a single man-made tunnel, which explains why the cricket remained undiscovered until now.
Morphological analysis of both male and female specimens showed that D. balrogi has a unique combination of physical features. The structure of the male epiphallus, the shape of the tenth tergite, and the form of the female ovipositor set it apart from other Dolichopoda species.
Molecular analysis confirmed this. DNA barcoding showed that the Kastellorizo population belongs to an evolutionary lineage alongside southwestern Anatolian Dolichopoda species, especially D. sbordonii and D. lycia. However, this is the first time an Anatolian Dolichopoda lineage has been documented within European territory.
A Biogeography Bridge
Kastellorizo’s location already makes it a unique case in the eastern Mediterranean. Although it is officially part of Greece, the island sits just a few kilometers from the Turkish mainland, and its plants and animals reflect this proximity. The discovery of D. balrogi fits this pattern since its closest relatives are not found on other Greek islands but along the coast of Anatolia.
This finding also adds to the evidence that Kastellorizo acts as a biogeographic bridge, hosting species with roots and connections that set them apart from the rest of the Aegean islands.
“These findings remind us that biodiversity discoveries are not limited to remote tropical forests or deep oceans,” added lead researcher Konstantinos Kalaentzis. “Even familiar landscapes and human-made structures can harbour species that have remained unnoticed.”
A Fragile Find
Cave-adapted organisms such as Dolichopoda crickets are particularly vulnerable. Their entire known range may extend only to a single tunnel, cave, or hillside. D. balrogi appears to only exist in this single man-made passage. Construction, flooding, or other disturbances to that habitat could eliminate the species before researchers fully understand it.
The authors note that documenting hidden subterranean fauna is a necessary first step toward protection, and that artificial underground environments should receive more attention as possible refuges for specialized cave-dwelling species.
The Greek islands are among the least studied archipelagos in the Mediterranean in terms of biodiversity. The discovery of a new species with Anatolian evolutionary roots in a single tunnel on a nine-square-kilometer island suggests that the region’s unexplored caves and crevices may harbor many more undiscovered species.

A multi-institutional team of researchers led by University of Connecticut Professor Zhe Zhu has developed a method for measuring the dynamic, real-time activity of urban environments from space, which they are calling an “Urban Pulse.”
The research team behind the novel urban activity metric said that monitoring a city’s Urban Pulse could help mitigate uncontrolled urban sprawl or decay and enable environmentalists and urban planners to intervene before disasters become unavoidable.
Measuring an Urban Pulse Could Reveal Neighborhoods ‘Not Doing Well”
Although environmentalists and urban planners have a wide range of tools to measure the activities within a city, Zhu notes that scientists have spent decades merely capturing the “outcome of urbanization,” such as a finished road or a newly completed home. However, the researcher and lead author of a study detailing the Urban Pulse methodology added that, even with all the current tools, “you don’t really see the dynamics within an urban area.”
According to a statement detailing the new approach, a city’s pulse is determined by all construction activity within it. Along with new construction, the metric includes repairs, infrastructure improvements, or expansion into previously undeveloped green spaces. When used correctly, the researchers said that it can help determine “if and where their city is not doing well.”
“This would allow (authorities) to be proactive rather than conducting a metaphorical autopsy after the decay of an area is evident,” the team explained.
Bridging the Gap Between Abstract Urban Theories and Measurable, Real-World Data
To test their approach, the team evaluated the Urban Pulse of six cities: Seattle, Shenzhen, Lagos, Mumbai, Dubai, and Mexico City. This involved a deep examination of what the team termed “decades of dense time-series data” collected by NASA’s Harmonized Landsat and Sentinel-2 (HLS) satellites for physical transformations in an urban environment, such as new construction, measurable infrastructure improvements, and demolition.
Instead of analyzing each city’s changes manually, the team evaluated the above changes on what they called “the neighborhood level” using a deep-learning and time-series-analysis approach called CAPES, developed by former UConn postdoctoral researcher Ji Won Suh. The team said that, by observing these “high-frequency rhythms of development” from a broad ‘outer space’ perspective, their approach “bridges the gap between abstract urban theories and measurable, real-world data.”
This figure visualizes Dubai’s rapid expansion as a glowing “urban pulse.” Mapping monthly construction data from the city’s top 65 most active locations, the ridge plot reveals how distinct neighborhoods grow through spiky, cyclical, and asynchronous bursts. Rather than a steady wave, urbanization unfolds as dynamic, localized heartbeats, exposing the complex rhythms driving a modern metropolis. Image Credit: Zhe Zhu/GERS Lab.
After examining CAPES’ results, the team found several key markers within the Urban Pulse. For example, the view from space revealed that growth within cities is not smooth and steady. Instead, Zhu and colleagues said that development happens in “abrupt, intense, and episodic bursts of construction.”
CAPES also revealed that the rhythms of an urban environment are cyclical. For example, while a city may show relatively steady growth on a broader level, individual neighborhoods go through “dramatic boom-and-rest cycles” of expansion and dormancy that don’t appear to follow predictable annual seasons.
The third pattern revealed by measuring the six cities’ Urban Pulse from space was that cities are “asynchronous,” meaning a single city does not ‘beat’ in unison. The team noted that neighborhoods “pulse at completely different times.” When it functions properly, this “uncoordinated rhythm” helps prevent the city’s infrastructure and labor markets from “overheating.”
Unlike previous methods for tracking a city’s evolution, the team noted that their Urban Pulse approach can help researchers “visualize a city’s reaction to global shocks.” For example, the team said that their analysis captured “the exact moment the COVID-19 pandemic triggered a widespread, synchronized ‘cardiac arrest’ in urban development worldwide.”
However, their new tool also revealed what the researchers termed “profound inequalities” in how individual cities recovered from the dramatic halt to urban growth. For example, the team said that the Urban Pulse of Shenzhen revealed synchronized ‘dips’ in activity, followed almost immediately by “rapid, policy-driven rebounds.” However, the same Orban Pulse analysis showed that the reactions in Mumbai and Mexico City were much more “muted.”
“It’s like in human beings,” Zhu explained. “When you get a disease, it’s not going to show up exactly the same in different people.”
A ‘Very Impactful Tool’ for Navigating Cities
Although the Urban Pulse metric offers a tantalizing tool for academics, the team noted real-world benefits for global policymakers, urban planners, and environmentalists, adding that “it serves as an early warning system.”
“By monitoring the rhythm, rate, and amplitude of neighborhood pulses, governments can identify early signs of urban decay or unsustainable sprawl and intervene before crises become entrenched,” they explained.
The team also suggested that making Urban Pulse data publicly available could “revolutionize how everyday people interact with their cities.” For example, an urban family considering a move to a new city or a new part of their current city could track a target neighborhood’s pulse to spot early warning signs of decay or early indicators of positive-trending growth. The same data could help business owners plan new locations or expanded service routes, depending on the business profile and the local Urban Pulse trends.
“This is going to be a very impactful tool influencing not only top-down policy decisions from governments but also bottom-up decisions from everyday people navigating their cities,” Zhu explained.

Third of world’s energy needs should come from electricity by 2035, says Murat Kurum, as priorities set out for this year’s UN climate summit
The world should aim to meet a third of its energy needs from electricity within a decade to cut greenhouse gas emissions, the host of the next UN climate summit has said.
While about a third of global electricity generation already comes from renewable sources, other energy-intensive sectors – chiefly transport, heating and industries – have lagged behind. Close to four-fifths of final energy still comes from fossil fuels, as a result.
As the United States grapples with record-breaking drought conditions across much of the country, the booming artificial intelligence industry appears to be on a collision course with water scarcity. New analysis reveals that approximately two-thirds of planned AI data centers are slated for construction in areas that have experienced some of the most severe drought conditions over the past year.
This concerning trend highlights a fundamental conflict between technological advancement and environmental sustainability. AI data centers are notorious for their enormous water consumption, requiring vast quantities of water for cooling systems to prevent the massive server farms from overheating. These facilities can consume millions of gallons of water daily, putting additional strain on already stressed water resources in drought-affected regions.
The timing couldn’t be worse for many communities already struggling with water shortages. The current drought has shattered previous records, leaving reservoirs at critically low levels and forcing water restrictions in numerous states. Yet the AI industry’s expansion continues largely unabated, with companies apparently prioritizing factors such as energy costs, tax incentives, and connectivity over water availability when selecting locations for new facilities.
This development raises serious questions about the sustainability of AI expansion and whether current planning approaches adequately consider long-term environmental impacts. As public concern grows over the water demands of AI infrastructure, communities and policymakers are increasingly calling for more responsible site selection and water-efficient technologies in data center development.
