## A Robot That Defies Two Worlds

Deep inside a laboratory at MIT, a giant tank of bright turquoise water sits beside a powerful array of fans and a collection of small flying machines. These robots are not just impressive pieces of engineering — they represent a fundamental leap in what machines can do. Inspired by the remarkable abilities of diving seabirds like the Atlantic puffin, researchers have created a robot that can both swim beneath the surface and soar through the open sky.

Mechanical engineer Raphael Zufferey leads the project. His fascination with the puffin stems from how effortlessly the bird navigates two drastically different environments — air and water — despite the enormous difference in their densities. That biological marvel became the blueprint for something no one had ever successfully engineered before.

## Engineering Inspired by Nature

The team's findings were published in the journal *Science*, detailing the design and performance of their new aerial-aquatic robot. The machine weighs roughly half a pound and stretches nearly three feet from wingtip to wingtip. Its translucent nylon wings are reinforced with carbon fiber struts, giving them both the strength and flexibility needed to function in two very different physical environments.

The development process took two full years. From the outset, the challenge seemed almost impossible. "Thinking of a wing that could operate in both somewhat efficiently seems implausible," Zufferey admits. Yet he and his team pressed forward, drawing from detailed studies of how puffins dive, swim, and take flight.

### Two Critical Design Decisions

While the robot's overall body plan mirrors that of a diving bird, the engineers made two significant departures from nature's template.

First, they chose to eliminate legs entirely. In robotics, legs introduce unnecessary mechanical complexity and control challenges. Instead, the team asked a bold question: could the robot launch itself directly from water to air using its wings alone?

Second, they opted against foldable wings, a feature common in real diving birds. Adding the joints and motors required for folding would have made the design too complicated. Instead, they engineered natural flexibility directly into the wing structure itself.

## How the Robot Works

One of the most innovative aspects of the design is the robot's open body frame. Rather than sealing the central housing — which contains the motor and battery — the team left it exposed, allowing water to flood the internal cavity freely. Every electronic component was individually waterproofed instead.

This approach serves two purposes. It keeps the robot light enough for efficient aerial flight, and it makes the machine neutrally buoyant in water, meaning it neither floats to the surface nor sinks to the bottom — it simply hovers in place at whatever depth it reaches.

During normal flight, the robot flaps its wings five to six times per second. To break free from the water's surface and launch into the air, however, it must double that rate to around ten flaps per second, generating enough speed and thrust to clear the surface in under a second.

Interestingly, most diving birds lack the raw wing power to achieve this on their own, which is why species like the puffin rely on their legs to run along the water before becoming airborne. The kingfisher is a notable exception, largely due to its exceptionally light body weight.

## A Stunning Real-World Test

To prove the concept works outside the laboratory, the research team took their robot to Lake Geneva in Switzerland. With the Alps forming a dramatic backdrop, the machine was submerged and then activated. Within less than a second, it burst from the calm water and climbed into the air — the burst of motion sounding remarkably like a real bird taking flight.

The engineers calculated the ideal launch angles and wing dimensions to maximize performance. On a single battery charge, the robot is estimated to cover nearly four miles by air or just over a mile through water — a combined range that actually exceeds the swimming and running distances of a sprint triathlon.

## What Experts Are Saying

Glenna Clifton, an animal movement biologist at the University of Portland who collaborates with roboticists, praised the achievement enthusiastically. "It is light and powerful and a monumental step in the performance at both swimming, flying, and transitioning between the two," she said.

Clifton also highlighted the broader scientific value of such bio-inspired machines. The relationship between biology and robotics flows in both directions: nature provides the inspiration for engineering breakthroughs, while the robots in turn help scientists better understand the biological principles behind animal movement.

## What Comes Next

Zufferey envisions a wide range of real-world applications for aerial-aquatic robots like this one. Coastal monitoring, tracking harmful algal blooms, assessing fish populations, and studying coastal erosion are all possibilities on his roadmap. The plan is to equip future versions with onboard sensors capable of collecting environmental data during both flight and underwater travel.

The robot could, for example, fly out to a remote coral reef, descend into the water, collect samples, and return — all without human intervention. Similar missions could involve monitoring whale pods or tracking the spread of algal blooms across large stretches of ocean.

For Zufferey, the greatest source of motivation remains the natural world itself. "You see that it has already been done in biology," he says. "So that gives you hope as a robotics researcher. It tells you that it should be possible."

MIT engineers built a half-pound aerial-aquatic robot inspired by diving seabirds. It can fly nearly 4 miles or swim over a mile on a single charge.

Meet the Bird-Inspired Robot That Can Both Fly Through the Air and Swim the Seas

The hunt for ancient life on Mars just got an important test run. Scientists confirmed that the Rosalind Franklin rover&apos;s sophisticated instrument can detect subtle differences in two stable molecules that could preserve evidence of past life for billions of years. But the team also uncovered a surprise: organic molecules in the Murchison meteorite appear to have been contaminated by fossil fuel pollution during their journey through Earth&apos;s atmosphere.

Mars was not always the cold, dry world we see today. Billions of years ago, scientists believe it may have been warm, wet, and wrapped in a much thicker atmosphere, creating conditions that could have supported simple microbial life. Even so, proving that life ever existed there remains one of the biggest challenges in planetary science.

NASA's rovers have already detected organic molecules in Martian rocks, but those compounds alone cannot confirm that life was once present. Beginning in 2030, the European Space Agency's Rosalind Franklin rover is expected to join the search with specialized instruments designed to look for stronger chemical evidence. Now, researchers from the Max Planck Institute for Solar System Research (MPS), the University of G&ouml;ttingen, and C&ocirc;te d'Azur University in Nice (France) have put one of the rover's key detection methods through a demanding test.

Searching for Ancient Martian Biosignatures

Finding convincing evidence of ancient Martian life means telling apart organic molecules created by living organisms from those produced through ordinary chemistry. Researchers believe two hydrocarbons, pristane (C 19 H 40 ) and phytane (C 20 H 42 ), could help answer that question.

These molecules originate from living organisms and are also found in petroleum on Earth. Because they are unusually stable, scientists think they could survive for billions of years under the right conditions.

"If life once existed on Mars, then molecules like pristane and phytane represent important molecular biosignatures that could have survived to this day," said MPS scientist Guillaume Leseigneur, lead author of the new study.

Pristane and phytane have another important characteristic that makes them attractive targets in the search for life. Like many organic compounds, they are chiral, meaning they exist in two mirror image forms called enantiomers. The two versions contain the same atoms but arranged as mirror images of one another, much like a person's left and right hands.

"Chirality is a valuable tool in the search for past extraterrestrial life," said co-author Uwe Meierhenrich of C&ocirc;te d'Azur University.

Living organisms typically produce almost exclusively one mirror image of a chiral molecule. Scientists expect the same pattern would apply to any life elsewhere in the universe because living systems reproduce themselves. In contrast, molecules formed without biology should contain both mirror image forms in roughly equal amounts.

The Rosalind Franklin rover will search for these subtle differences using the Mars Organic Molecule Analyzer (MOMA), an instrument developed and built under the leadership of the MPS. MOMA combines a gas chromatograph, a mass spectrometer, small furnaces, and an excitation laser.

Rock samples are first heated in the furnaces to release volatile compounds. Those gases are then analyzed and passed through specially coated capillary tubes. Because the mirror image versions of the same molecule interact differently with the coatings, they move through the tubes at different speeds, allowing the instrument to separate them.

For the new study, researchers used identical replicas of MOMA's capillary tubes. For the first time, they successfully separated the chiral forms of both pristane and phytane, despite the molecules being extremely unreactive.

"Chiral separation of pristane and phytane requires high instrument sensitivity and measurement accuracy, both of which we show MOMA can achieve," explained co-author and MOMA team member Fatma Yesil Sahan from the MPS.

Instead of Martian rocks, the team tested samples from the famous Murchison meteorite, which fell in Australia in 1969. Like many meteorites, it contains a mixture of organic compounds. Some were present when the meteorite formed, while others likely came from biological contamination after it landed. The researchers initially suspected pristane and phytane belonged to this second category.

The results, however, told a different story.

The meteorite contained equal amounts of every mirror image version of pristane and phytane. That pattern does not match biological material that could have contaminated the meteorite where it was found.

Instead, the researchers concluded the contamination was probably picked up while the meteorite passed through Earth's atmosphere, where it encountered aerosols produced by fossil fuel combustion.

Comparisons with pristane and phytane found in oil shales supported that explanation. These sedimentary rocks contain petroleum precursors that have spent millions of years deep underground.

"Petroleum forms in these rocks over millions of years at great depths under the influence of heat and pressure," said co-author Manuel Reinhardt from the University of G&ouml;ttingen.

Over time, those conditions erase the natural imbalance between the mirror image forms of the molecules, leaving them in equal proportions. That closely matches what the team observed in the Murchison meteorite.

Preparing for the Search for Life on Mars

The researchers say the work does more than validate MOMA ahead of its mission to Mars. It also raises new questions about how organic molecules found in meteorites acquire contamination and what increasing levels of petroleum related pollution in Earth's atmosphere may mean for future studies.

MOMA is part of ESA's ExoMars Mission to Mars and was developed and built under a program of, and funded by, the European Space Agency.

## Trees Keep Absorbing Carbon Even After Growth Seasons End

A groundbreaking new study has revealed that oak trees continue drawing carbon dioxide from the atmosphere long after their annual growth has stopped — a finding that could fundamentally change how scientists model carbon storage in forests around the world.

Published in *Science Advances*, the research challenges a widely held assumption in climate science: that photosynthesis and tree growth go hand in hand. According to the findings, the two processes are far more independent than previously understood, and that distinction carries serious implications for how we predict forests' role in combating climate change.

## The Long-Held Assumption That No Longer Holds

Forests have long been recognized as one of Earth's most powerful natural defenses against rising temperatures. Trees absorb CO₂ through photosynthesis and lock much of that carbon into their trunks, branches, and root systems — sometimes for hundreds or even thousands of years. This carbon sequestration has led scientists and climate modelers to assume that higher levels of atmospheric CO₂ would drive faster photosynthesis, which in turn would accelerate tree growth and increase long-term carbon storage.

The new research suggests that chain of logic may be flawed.

"Right now, most models assume that if you have photosynthesis, you have growth. We find that's not the case," said lead author Mukund Palat Rao, an ecoclimatologist at Lamont-Doherty Earth Observatory, part of Columbia Climate School. "Just because there is more photosynthesis might not necessarily mean more tree growth in the future."

## How Photosynthesis and Growth Actually Differ

During photosynthesis, trees use sunlight to convert CO₂ and water into sugars, releasing oxygen in the process. That captured carbon stays inside the tree — but not all of it becomes wood.

Some carbon is built into the woody tissue of trunks, branches, and roots, where it can remain stored for centuries. The rest goes toward producing leaves and fruit, fueling metabolic processes, or being released into the surrounding soil to support microbial life, aid nutrient absorption, and help the tree fend off disease.

Because woody biomass stores carbon over such extended timescales, knowing how much photosynthesized carbon actually becomes wood is essential for accurately estimating how much forests can help offset greenhouse gas emissions.

"Understanding how photosynthesis and growth are linked is very important from the perspective of understanding how forests will store carbon over long time scales," Rao explained.

## How the Study Was Conducted

To explore the relationship between carbon uptake and tree growth, Rao and his team combined multiple streams of data collected across 137 oak forest sites in the eastern United States and California.

The researchers analyzed satellite imagery capable of detecting photosynthetic activity, hourly CO₂ measurements taken from tree canopies, and trunk sensors that tracked subtle daily changes in tree diameter. They also incorporated tree ring records and temperature data stretching back to 1950.

Together, these sources gave the team a detailed, daily picture of how photosynthesis, carbon absorption, and physical growth related to one another across different seasons and climate conditions.

## A Clear Divide Between Growth and Carbon Capture

### Eastern U.S. Oak Forests

The data revealed a striking gap between when trees grow and when they continue to absorb carbon. In eastern U.S. forests, oak trees typically grew between May and July but kept photosynthesizing all the way through October. Approximately 36 percent of their total annual carbon uptake occurred after growth had already halted for the season.

### California Oak Forests

California oaks followed a different seasonal schedule but showed the same underlying pattern. Growth generally took place from December through April, tapering off by mid-summer and stopping entirely by August — yet photosynthesis continued well beyond that point. Around 26 percent of their yearly carbon absorption happened after growth had ceased.

## Why Do Trees Stop Growing While Still Photosynthesizing?

The explanation, according to Rao, comes down to water. Tree growth depends on internal water pressure within cells, and that pressure drops sharply when conditions turn hot and dry.

"The moment you have dry and hot conditions, growth activity stops pretty instantly while photosynthesis seems to continue at a slightly decreased rate," Rao said.

The carbon that trees capture after growth ends doesn't simply disappear. Some of it is stored temporarily and used to fuel growth when the next season begins. The rest goes toward developing new roots and leaves or is metabolized to sustain the tree's living cells through winter dormancy.

What remains unclear is how much of that post-growth carbon eventually becomes permanent woody biomass versus how much is released back into the atmosphere over shorter timeframes.

## What This Means for Climate Forecasting

The implications of this research extend well beyond forest ecology. Climate models that project how much carbon forests will store in a warming world may be significantly overestimating that capacity if they assume photosynthesis reliably translates into wood production.

The study also found that the gap between photosynthesis and growth widened during years with greater swings between wet and dry weather conditions. Since climate change is expected to increase weather variability across many regions, this disconnect could become even more pronounced in the decades ahead — further reducing the reliability of current carbon storage projections.

## Questions That Still Remain

Rao and his colleagues are now turning their attention to other tree species, forest types, and climates to determine whether the same patterns hold more broadly. He expects the degree of separation between photosynthesis and growth will differ depending on the ecosystem, but acknowledges that many fundamental questions are still unanswered.

"I don't really have answers yet," he admitted. "There are many questions still left to address."

What is clear, however, is that the relationship between trees and carbon is far more nuanced than scientists once believed — and that understanding those nuances will be critical for building accurate predictions of Earth's climate future.

New research shows oak trees continue absorbing CO₂ long after growth ends, challenging climate models and reshaping carbon storage forecasts for forests.

## A Fire That Refuses to Die

For more than eight days, a relentless blaze has consumed a towering mountain of garbage at the Jatiwaringin landfill, located on the outskirts of Jakarta, Indonesia. Spreading across more than 15 hectares, the fire has blanketed surrounding neighborhoods in dense, poisonous smoke, forcing hundreds of residents to abandon their homes and seek emergency shelter.

Firefighting teams have deployed an extensive arsenal of resources — including helicopters, water tankers, bulldozers, and drones — in an effort to bring the inferno under control. Authorities remain hopeful the fire can be fully extinguished before the week is out, but environmental advocates warn this disaster is far more than an isolated incident.

## Residents Left Gasping for Air

The human toll of the blaze has been severe. Health officials have recorded at least 234 residents seeking medical attention for respiratory problems directly linked to the fire, with 72 of those cases diagnosed as acute respiratory tract infections.

Sarmanah, a 45-year-old local resident, described the harrowing conditions that forced her and her child to flee their home.

"The smoke was so thick you couldn't see anyone," she told reporters. "It stings the nose, makes you cough and have a runny nose, and makes you unable to breathe. We were forced to leave because we couldn't take it anymore."

Another displaced resident, 37-year-old Tosiyani, said she was barred from returning home due to dangerous levels of toxic gas in the smoke. Measurements taken by Indonesia's Ministry of Environment confirmed that air quality near the landfill had reached hazardous levels, though conditions have shown some improvement in recent days.

## Why the Fire Is So Difficult to Extinguish

Djohan Darmawan, Director of Emergency Operations Control Coordination at the National Disaster Management Agency (BNPB), explained that the fire presents unique challenges for firefighters. Unlike a conventional surface fire, this blaze is smoldering deep within the compacted layers of rubbish — making it extraordinarily difficult to locate and suppress.

Active fire spots continue to burn in several waste piles, particularly in areas to the west and south of the landfill site.

The Indonesian environmental organization Walhi (Forum for the Environment) has attributed the fire's origin to a buildup of methane gas produced by decomposing organic waste — a direct consequence of the country's largely unregulated open dumping practices.

"This is a time bomb of accumulated waste management problems that have been ignored for years without fundamental improvements," said Wahyu Eka Styawan, a Walhi campaigner.

## A Landfill Stretched Far Beyond Its Limits

At the heart of this crisis lies a fundamental mismatch between waste generation and infrastructure capacity. According to Walhi, the Jatiwaringin landfill is designed to handle up to 2,700 tons of waste per day — yet that figure accounts for only 59% of the total waste produced by Tangerang Regency alone.

The overflow has led to widespread illegal open dumping across Tangerang, with informal trash mountains sprouting up within meters of residential neighborhoods. Long before the fire erupted, locals living in the shadow of Jatiwaringin's waste piles complained of overwhelming odors, persistent fly infestations, and constant anxiety over the threat of garbage landslides.

When methane accumulation is compounded by increasingly intense heat waves driven by the climate crisis, these dumping sites can effectively become tinderboxes.

"As soon as there is a small spark or heat, the methane gas under the mountain of rubbish immediately ignites," Wahyu explained.

## A Pattern of Recurring Disasters

The Jatiwaringin fire is not an anomaly — it is part of a disturbing pattern. In 2023, a string of major landfill fires broke out across Indonesia. The Sarimukti Landfill in Bandung Regency burned through dozens of hectares, with cigarette butts and methane buildup suspected as causes. Months later, a separate landfill fire in Tangerang destroyed approximately 80% of a 35-hectare site under similar circumstances.

The fire at Jatiwaringin reportedly ignited on June 30, started by a small spark that was rapidly spread by strong winds across multiple sections of the site — including areas laden with deep waste accumulation that proved nearly inaccessible to emergency crews.

## Government Response and Systemic Failures

Rizal Irawan, Deputy for Environmental Law Enforcement at Indonesia's Ministry of Environment and Forestry, confirmed that a formal investigation into the fire's cause will be launched once the blaze is fully contained. He also noted that the Jatiwaringin landfill had already received administrative sanctions in 2025 for inadequate management practices.

Looking ahead, the Ministry has announced plans to evaluate 390 landfills across Indonesia in early August 2026. Authorities have also instructed regional governments to transition toward a controlled landfill system, in which waste is flattened and compacted by heavy machinery before being covered with periodic layers of soil. This method can significantly reduce methane buildup, lower disease risks, and improve overall site conditions.

However, environmental campaigners remain skeptical that meaningful change will follow without genuine political commitment.

"Regulation is not implemented because there is no firmness and sanctions, the budget for waste management in the regions is minimal, and there is a lack of focus on educating residents about sorting organic waste from home," said Wahyu.

## An Ecological Crisis Born of Neglect

Walhi has characterized the Jatiwaringin disaster as an "ecological disaster resulting from systemic negligence" — a damning indictment of decades of inadequate waste policy at both the national and regional levels.

Until Indonesia's central and local governments demonstrate a concrete, sustained commitment to overhauling their waste management infrastructure — backed by meaningful enforcement, adequate funding, and public education — experts warn that fires like this one will continue to ignite, and communities will keep paying the price.

## Northern Ireland Takes a Historic Step Toward Greener Woodland Coverage

Northern Ireland has officially launched its first-ever Tree Planting Action Plan — a landmark strategy aimed at dramatically increasing the region's woodland cover from its current 8.6% to 12% by 2050. To stay on course, planting rates will need to more than triple by 2032.

## Why This Plan Matters

With just 8.6% of its land covered by trees, Northern Ireland ranks among the least wooded regions in Europe. The gap is stark when compared to its closest neighbors: Scotland leads the UK with 19% woodland cover, followed by Wales at 15%, England at 10%, and even the Republic of Ireland, which sits at 11%. Northern Ireland trails behind all of them.

Environment Minister Andrew Muir described the plan as "ambitious" and emphasized the wide-ranging benefits that greater woodland cover can deliver.

"Woodland cover delivers so many benefits — whether it's carbon storage, nature recovery, flood resilience, or the outdoor recreation opportunities it creates across Northern Ireland," Muir said.

## What the Action Plan Includes

The strategy outlines **10 strategic actions** supported by 31 individual implementation measures, organized across four key areas. It was developed collaboratively by the Department of Agriculture, Environment and Rural Affairs (DAERA), alongside the Woodland Trust, the Confederation of Forest Industries (CONFOR), forestry companies, environmental non-governmental organizations (eNGOs), the Ulster Farmers' Union, NI Water, and local councils.

### Key Targets

- Under Northern Ireland's first Carbon Budget (2023–2027), **2,585 hectares** of new woodland are committed for planting.
- An additional **1,205 hectares** are still needed to meet that near-term target.
- A further **50,000 hectares** of new woodland must be established to fulfill the 2050 Climate Change Act goal of 12% woodland cover.

## Industry and Farming Voices Weigh In

### Woodland Trust Welcomes the Direction

John Martin, Chief Executive of the Woodland Trust in Northern Ireland, called the plan long overdue. He acknowledged that landowner enthusiasm for tree planting has historically been limited but expressed hope that the action plan's measures would help shift that mindset.

"This starts to take us in the right direction in terms of commitment towards planting trees in the wider countryside," Martin said. "Hopefully, through the review of what's happening within the action plan, we'll start to see that appetite improve."

### Timber Industry Eyes Economic Opportunity

Nigel Manley, Chair of the Confederation of Forest Industries, highlighted the commercial case for expanding forestry. He pointed out that the UK currently imports millions of cubic metres of wood annually, and demand is projected to rise — particularly as housing construction needs grow across Northern Ireland, the wider UK, and the Republic of Ireland.

"If we get behind this Tree Planting Action Plan and implement the actions, we can enjoy the sustainability it brings — jobs, investment, and critically, sustainable timber production," Manley said.

### Farmers Call for Voluntary Participation

The Ulster Farmers' Union welcomed the plan but was clear that farmer autonomy must remain central to its delivery. President John McLenaghan praised efforts to simplify grant access and improve the flow of information to farmers, while cautioning against a one-size-fits-all approach.

"Tree planting won't suit every farm, and it should never be presented as though it does," McLenaghan said. "What matters to us is that farmers have the opportunity to engage in woodland if it makes sense for their own business — not because they're being targeted or because other payments are tied to it."

He also stressed the importance of honest communication: "We've pushed for balanced messaging so that the information coming out of this plan gives farmers a true, fair, and accurate picture of both the opportunities and the challenges."

## A Crucial Step Forward

Northern Ireland's first Tree Planting Action Plan represents a significant commitment to reversing decades of deforestation and environmental neglect. While the targets are demanding and the road ahead is long, the cross-sector collaboration behind the plan signals a shared recognition that expanding woodland cover is not just an environmental priority — it is an economic and social one too.

Northern Ireland launches its first Tree Planting Action Plan, targeting 12% woodland cover by 2050 with 10 strategic actions and cross-sector collaboration.

## A Sweltering Anniversary 250 Years in the Making

When Thomas Jefferson stepped outside to record the temperature on July 4, 1776, his thermometer read a comfortable 76 degrees Fahrenheit in Philadelphia. Fast forward two and a half centuries, and the scene looked dramatically different. Millions of Americans across the eastern United States found themselves sweating through extreme heat warnings as they tried to celebrate that historic milestone.

The powerful heat dome that smothered the Midwest and Atlantic coast eventually gave way to severe storms and flash flooding — a one-two punch of extreme weather that the National Weather Service had anticipated well in advance.

## Parades Canceled, Emergency Rooms Overwhelmed

Many cities took proactive steps to protect residents before the holiday arrived. Philadelphia and Washington, D.C., scrapped their traditional Independence Day parades entirely, while Boston delayed public access to its beloved annual fireworks celebration until 4 p.m. to limit prolonged outdoor exposure during peak heat hours.

Despite those precautions, the human toll was significant. At least 40 deaths were linked to the heat wave by local authorities — 29 in New Jersey, 4 in Philadelphia, 4 in Illinois, and 3 in New York. Emergency departments across a wide swath of the Eastern Seaboard, stretching from New York down to Georgia, recorded "extreme" rates of heat-related illness visits, according to the Centers for Disease Control and Prevention's real-time heat illness tracking system.

In Washington, D.C., where temperatures climbed to 102 degrees over the weekend, emergency responders were kept busy throughout National Mall celebrations. DC Fire and EMS logged 96 patient contacts, George Washington University handled 289, and the U.S. Department of Health and Human Services recorded 314 additional contacts. In Boston, 34 of the 108 people treated by emergency services at a Fourth of July event were suffering from heat-related conditions. Between Wednesday and Saturday, 84 total 911 calls in Boston were tied to the heat.

## The True Death Toll Is Likely Higher

Experts caution that the official fatality numbers almost certainly underrepresent the full impact of extreme heat. Heat-related deaths are notoriously difficult to quantify, partly because heat frequently worsens existing medical conditions rather than serving as a clear, standalone cause of death.

"Teasing out which deaths are due to extreme heat and which are due to other causes is not an exact science," said Steven Cohen, director of the sustainability management program at Columbia University and a former policy analyst for the U.S. Environmental Protection Agency. Without a universal standard for attributing deaths to climate-related events, the numbers that reach official reports often fall short of reality.

## This Is Not an Anomaly — It's a Preview

Climate scientists are urging Americans not to treat this Fourth of July as a rare, isolated event. The average number of heat waves across the United States has already doubled since the 1980s, driven primarily by climate change fueled by the burning of fossil fuels. Heat waves are not only occurring more frequently — they are also growing more intense and lasting longer.

"It's not an anomaly. It's a preview," said Michael Rawlins, associate director of the Climate System Research Center at the University of Massachusetts Amherst.

Rawlins pointed to temperature data from across New England as further evidence of a troubling shift. From June 1 through July 5, weather stations throughout the region recorded their highest temperatures ever — or came dangerously close to breaking records.

"That's not a heat wave — that's a season," Rawlins said.

### The Human Cost Behind the Climate Data

Rawlins described the surge in emergency calls and hospital visits as a direct reflection of what climate scientists have been warning about for decades. "These numbers are the human cost of what the climate data is telling us," he said.

While he praised cities for stepping up — canceling events, opening cooling centers, and improving emergency response — he urged against any sense of complacency. "I wouldn't want anyone to get complacent in thinking that we're prepared for what the future may bring," Rawlins said, stressing that reducing greenhouse gas emissions remains the most critical long-term solution.

## Cities Are Adapting, But There Are Limits

Cohen described the intensifying heat as the "new normal" and noted that many municipalities are already making adjustments. These include keeping air-conditioned public buildings open for extended hours, strengthening local emergency response infrastructure, and encouraging real estate developers to factor climate risk into construction planning.

However, Cohen was clear-eyed about the limitations of adaptation alone. "We're learning how to adapt to it. But there's a limit to how much we can adapt," he said.

## Public Awareness Is Growing

One silver lining, both experts noted, is that Americans are increasingly connecting extreme weather to climate change — and taking warnings more seriously. A 2025 poll conducted by the University of Chicago found that approximately nine in ten Americans who personally experienced extreme weather believe climate change played a contributing role.

"There's more awareness of the health impacts of extreme weather," Cohen said. "People are paying attention to it because it's no longer something that happened to somebody else. It's something that happened to my cousin, my brother, my friend or myself."

As the planet continues to warm, the message from climate scientists is unambiguous: sweltering Independence Days like this one are not going away. If anything, they are only getting started.

Record heat waves struck millions on Independence Day 2025. Climate experts warn this dangerous new normal will only intensify as global temperatures rise.

## A Strange Discovery Nearly a Mile Below the Surface

Deep beneath the Black Hills of South Dakota, engineers responsible for maintaining one of the world's most extraordinary underground laboratories noticed something they couldn't immediately explain. During heavy rainstorms, the airflow inside their tunnel network would behave erratically — sometimes weakening dramatically, and in certain areas, reversing direction altogether.

It wasn't a minor fluctuation. It was a measurable, repeatable phenomenon that nobody had a solid explanation for. That mystery would ultimately lead to a scientific breakthrough with implications for underground operations across the globe.

## Inside the Sanford Underground Research Facility

The Sanford Underground Research Facility, known as SURF, sits nearly a mile beneath the earth in Lead, South Dakota. Originally a gold mine, the site was converted into a cutting-edge science laboratory where researchers conduct experiments that require the natural shielding only deep underground environments can provide.

While mining operations have long since ceased, a dedicated team of mining engineers still manages the facility's vast network of tunnels and shafts. Their responsibilities cover two fundamental systems: ventilation and water management. Both are non-negotiable when it comes to worker safety and operational integrity.

Under normal conditions, fresh air flows into the facility through two primary intake shafts and exits through two separate exhaust shafts. One of those exhaust routes — known as 5 Shaft — plays a secondary but critical role during storms: it serves as an overflow channel, routing excess rainwater down into a deep underground reservoir where it can later be pumped back to the surface.

## The Moment Engineers Noticed Something Was Wrong

Jason Connot joined SURF as a mining engineer in 2019 and quickly took charge of overseeing its ventilation systems. It didn't take long before he and his team began observing irregular airflow patterns during periods of intense rainfall.

"We noticed our fan would go haywire at 5 Shaft. Some areas would show reduced or even reversed airflow during large rain events," Connot said.

The team could see the changes happening in real time, but the cause remained elusive.

"At first, we didn't know what was going on with the airflow in large rain events. We could all see these airflow changes occurring throughout the underground, and we were like, why is this happening?" Connot recalled.

### A Key Clue Emerges

The first real breakthrough came during a routine test of the shaft deluge system. Airflow sensors located on the 4850 Level — instruments built and installed by local high school science teacher Steve Gabriel and his students — recorded an unexpected spike in air movement. Gabriel would later join SURF full-time as a ventilation technician.

That observation planted a seed. The installation of Maestro airflow sensors on the 2000 Level as part of an upgraded automated ventilation control system provided even sharper data, giving the engineering team a far more detailed picture of what was actually happening underground.

"We felt that airflow increase on the 4850 Level during that test. That's what made the correlation and triggered everything," Connot said.

## The Piston Theory: Water as an Airflow Driver

The team began to form a hypothesis. When rainfall exceeded the underground pumping system's capacity, engineers redirected surplus water down 5 Shaft into the deep pool below — essentially using the shaft as an overflow spillway. Their theory was that this cascading column of water was behaving like a syringe or a piston, physically displacing air as it plunged downward through the confined shaft.

It was a compelling idea, but scientific confirmation was needed.

Connot dove into the existing research literature and discovered something encouraging: similar phenomena had been documented in large municipal sewer systems. Those studies contained fluid dynamics equations that described how moving water in enclosed spaces could exert significant force on surrounding air.

Working alongside colleagues at South Dakota Mines, Connot adapted those equations to reflect the specific dimensions and conditions at SURF. The results were striking.

"When we added our numbers and parameters to the model, everything came out spot on," Connot said. "You would not think the weight of water droplets could move so much air."

## Why This Discovery Matters Far Beyond SURF

The implications of this research reach well beyond one laboratory in South Dakota. Underground mines around the world deal with both water infiltration and emergency ventilation scenarios — and the two are more connected than previously understood.

### A Critical Safety Consideration

Connot pointed to a particularly important real-world scenario: fire response. In the event of an underground fire, engineers may deliberately flood a shaft with water from the surface to help control the situation. If that influx of water simultaneously alters airflow patterns — potentially pushing smoke in unexpected directions — the consequences could be severe.

"If there's ever a fire, mining engineers will sometimes turn a valve on up top and just dump water down the shaft. Knowing this can change the airflow is critical information for everyone. We tested this, we've seen it occur," Connot said.

Bryce Pietzyk, Director of Underground Operations at SURF, emphasized how this research transforms the team's ability to anticipate and manage ventilation behavior.

"Thanks to this work, we're able to be way ahead of airflow issues, predict what will happen, and configure ventilation controls in the right manner," Pietzyk said. "No one had previously taken the time to grasp this issue — but it's absolutely critical."

## From Curiosity to Published Science

Connot's findings were formally published in the journal *Mining, Metallurgy & Exploration* under the title *Effects of Water Inflows on a Mine Ventilation System: A Case Study*. The research represents a rare opportunity — made possible by SURF's dual identity as both an operational facility and a research environment — to thoroughly investigate a phenomenon that active mining operations rarely have the time or resources to study in depth.

Dr. Andrea Brickey, a professor of Mining Engineering and Management at South Dakota Mines and Connot's academic advisor, praised both the quality of the work and the determination behind it.

"He identified a phenomenon impacting ventilation systems and his curiosity drove him to want to determine how to predict that behavior. He succeeded, and his work is helping SURF and an entire industry," Brickey said.

What began as an unexplained anomaly during a rainstorm has become a meaningful contribution to underground safety science — proof that even in environments humans have worked in for centuries, nature still has secrets worth uncovering.

Engineers at the Sanford Underground Research Facility discovered that falling rainwater acts like a piston, reversing airflow nearly a mile underground.

How Falling Rainwater Was Secretly Controlling Airflow Nearly a Mile Underground

## A Better Way to Measure Dangerous Cholesterol?

Every year, millions of Americans roll up their sleeves for a routine cholesterol blood test — but a groundbreaking new study suggests that many of them may be getting the wrong one. Research from Northwestern Medicine indicates that a test measuring apolipoprotein B, commonly known as apoB, may be significantly more effective than the widely used LDL cholesterol test when it comes to determining who needs more aggressive cardiovascular treatment.

The findings, published in the prestigious medical journal *JAMA*, could have sweeping implications for how doctors across the United States approach cholesterol management and heart disease prevention.

## What Is ApoB and Why Does It Matter?

For decades, physicians have relied on LDL — often labeled "bad" cholesterol — along with non-HDL cholesterol readings to decide when a patient should begin or intensify cholesterol-lowering therapy, such as statins. While these measurements offer valuable insight, researchers argue they fall short of painting a complete picture of a person's true cardiovascular risk.

ApoB testing takes a fundamentally different approach. Rather than measuring the amount of cholesterol in the blood, it counts the actual number of harmful cholesterol-carrying particles circulating in the bloodstream. Since it is these particles — not just the cholesterol they carry — that embed themselves in artery walls and form dangerous plaques, apoB offers a more direct and accurate gauge of heart disease risk.

"Research strongly shows that apolipoprotein B is better at identifying who is at risk, because it counts the total number of harmful particles in the blood," said study lead author Ciaran Kohli-Lynch, an assistant professor of preventive medicine at Northwestern University Feinberg School of Medicine.

## How the Study Was Conducted

### A Large-Scale Computer Simulation

To compare the effectiveness of different cholesterol testing strategies, the research team developed a sophisticated computer model simulating 250,000 American adults who were eligible for statin therapy but had not yet been diagnosed with cardiovascular disease.

The simulation evaluated three distinct approaches to guiding cholesterol treatment — one centered on LDL levels, one on non-HDL cholesterol, and one on apoB. In each scenario, when patients failed to meet their designated target, treatment was escalated, first by switching to more potent statins and then by adding the medication ezetimibe if necessary.

Researchers tracked each strategy across a patient's lifetime, measuring outcomes that included heart attacks, strokes, overall life expectancy, quality of life, and total healthcare costs.

### ApoB Came Out on Top

Across every meaningful measure, the apoB-guided strategy outperformed the other two approaches. It prevented more cardiovascular events, improved health outcomes, and — critically — did so in a way that remained cost-effective for the U.S. healthcare system.

"We found that apoB testing to intensify cholesterol-lowering medication would prevent more heart attacks and strokes than current practice, and that these health benefits were achieved at a cost that represents good value for U.S. healthcare payers," Kohli-Lynch stated.

The researcher also noted that this marks the first comprehensive analysis to confirm that apoB-guided treatment is not only clinically superior but also economically viable.

## Why ApoB Isn't Already Standard Practice

Despite mounting evidence supporting apoB as a superior cardiovascular risk marker, it remains largely absent from routine clinical care. One major barrier is practicality — apoB typically requires an additional blood draw beyond the standard cholesterol panel, adding both cost and inconvenience for patients and healthcare providers alike.

The central question driving this research was straightforward: Is the added expense of apoB testing justified by the clinical benefits it delivers? Based on the study's findings, the answer appears to be a resounding yes.

## Rising Stakes in Cholesterol Management

The timing of this research is particularly significant. Earlier this year, the American Heart Association, joined by ten other leading medical organizations, released updated guidelines recommending that many individuals begin cholesterol-lowering therapy at younger ages than previously advised.

As more people become eligible for treatment, and as a growing arsenal of cholesterol-lowering medications becomes available, the need to accurately identify who will benefit most from intensive therapy has never been greater.

"This means it is increasingly important to accurately identify who would benefit most from intensive treatment," Kohli-Lynch emphasized.

Heart disease remains the number one cause of death in the United States, accounting for enormous human and financial costs. If apoB testing were to become a standard part of cardiovascular risk assessment, experts believe it could meaningfully shift those numbers — saving lives while delivering measurable value to the broader healthcare system.

The study, formally titled *"Cost-Effectiveness of ApoB, Non-HDL-C, and LDL-C Goals for Primary Prevention Lipid-Lowering Therapy,"* was supported by an American Heart Association Career Development Award. Additional Northwestern University co-authors included Drs. John Wikins and Samuel Luebbe.

New research shows the apoB blood test may prevent more heart attacks than standard LDL testing. Here's what that means for your cardiovascular health.

Are Millions of Americans Getting the Wrong Cholesterol Test?

## Massive Wildfire Triggers Mass Evacuation in Southern France

A rapidly spreading wildfire has forced more than 10,000 residents to abandon their homes across a string of small towns and villages in southern France, as the country continues to battle the devastating effects of an early summer heatwave that has gripped much of Europe.

Authorities issued mandatory evacuation orders for residents across more than a dozen communities nestled in the foothills of the French Pyrenees, close to the Spanish border. The blaze, centered near Trévillach in the Pyrénées-Orientales region not far from Perpignan, has already consumed a minimum of 4,600 hectares — roughly 11,366 acres — of land.

## Deteriorating Conditions and High Winds Fuel the Crisis

French Interior Minister Laurent Nunez issued a stark warning on national television channel TF1, cautioning that the situation remained highly volatile. "This morning conditions are deteriorating again," he told viewers. "Today the battle resumes."

Emergency services have flagged strong winds as a major concern, warning that gusts could rapidly accelerate the fire's spread. Local residents described scenes of near-panic as the flames advanced with frightening speed.

"It came within 300 metres of the houses. We were shocked by how fast it spread — it was staggering, bordering on panic," said Patrice, a resident of Trévillach, speaking to the AFP news agency.

## Tour de France Forced to Restrict Spectator Access

The wildfire has also cast a shadow over one of the world's most celebrated sporting events. Tour de France organizers have urged fans and non-essential personnel to stay away from the final 40 kilometers of Monday's third stage, which concludes in Les Angles — located within the fire-affected Pyrénées-Orientales region.

The 195.9-kilometer stage begins in Granollers, Spain, and the convoy of team support vehicles that traditionally trails the peloton will be dramatically reduced to keep roads accessible for emergency responders.

Race director Christian Prudhomme emphasized the gravity of the situation: "An exceptional fire calls for exceptional measures for the Tour. We invite the public not to come to the edge of the race or to the finish site."

## European Union Mobilizes Emergency Aircraft

The scale of the disaster has prompted an international response. European Commission President Ursula von der Leyen announced that the EU would deploy four firefighting aircraft — stationed in Cyprus and Sweden — to support French emergency operations on the ground.

## Wildfires Also Ravage Neighboring Spain

The crisis is not confined to France alone. Across the border, wildfires have scorched more than 2,200 hectares within the protected natural reserve of Les Gavarres in Catalonia. Spanish authorities reported late Saturday that the blaze had been stabilized and was expected to be fully extinguished within the week.

Further south, in the eastern province of Castellon, approximately 500 people were evacuated after a separate wildfire breached the boundaries of the Sierra de Espadan national park.

## Record Heat Persists Across the Region

Temperatures across south-western France are forecast to climb back toward 40°C this week. Parts of Portugal and Spain have already surpassed that threshold. BBC Weather Lead Forecaster Matt Taylor noted that while this heatwave may not shatter the records set in June, it remains highly unusual for the time of year.

"With the heat expected to persist into next week and little widespread rain forecast, the risk of further wildfires will remain elevated," Taylor warned.

During June's unprecedented heatwave — when temperatures in some areas hit 42°C — France recorded its hottest day ever on a nationwide average basis on June 24. The extreme heat contributed to at least 2,025 excess deaths in France, 1,222 in Belgium, and approximately 480 in the Netherlands.

## Climate Change: The Driving Force Behind Europe's Worsening Summers

Scientists and climate analysts continue to point to climate change as the primary driver behind Europe's increasingly severe summer conditions. According to the Copernicus Climate Change Service, Europe is currently the fastest-warming continent on Earth, heating up at twice the rate of the global average.

This accelerating warming trend is intensifying summer heatwaves, straining water resources across the continent, and fueling more frequent and destructive wildfires — a pattern experts warn is set to worsen in the years ahead unless meaningful action is taken.

A massive wildfire near Perpignan has displaced over 10,000 people in southern France, disrupted the Tour de France, and spread into neighboring Spain.

## Jersey Leader Backs Public Purchase of Iconic Golf Course

Jersey's Chief Minister Lyndon Farnham has thrown his support behind efforts to bring a prominent golf course site into public ownership, following a growing community campaign urging the government to act before the land falls into private hands.

### Les Mielles Listed for Nearly £10 Million

Les Mielles Golf & Country Club, located in St Peter, was recently placed on the market with a guide price of £9.95 million. The listing has prompted swift action from local campaigners, who fear the site could be lost to private development if the government fails to intervene.

A public petition launched by local resident Matt Topman has already gathered over 600 signatures. Topman is urging the government to explore funding options that would allow the purchase of the site, with plans to restore the majority of the land to its natural state, introduce an educational and activities component, and repurpose the existing clubhouse as a national centre.

## A Once-in-a-Generation Opportunity

Topman drew comparisons to previous successful conservation efforts at Plémont and Grève de Lecq, highlighting how community-driven initiatives had led to meaningful land preservation in Jersey before.

"It's such a large parcel of land within our national park, and the fact that it has come up for sale right now creates a sense of urgency," Topman said. "Some form of rewilding, given its natural setting, would be wonderful — whether that's integrated with the existing golf course or involves a full change of use. This is an open canvas and a truly once-in-a-generation opportunity."

Topman added that he would welcome involvement from a private investor as well, noting that the petition was primarily intended to spark a broader conversation about the site's future.

## Farnham Signals Government Interest

In a recent interview with BBC Jersey, Chief Minister Farnham openly expressed his enthusiasm for the idea.

"I fancy that coming into public ownership somehow," he said, signalling that the government would seriously explore the possibility.

Farnham indicated his intention to consult with the National Trust of Jersey, envisioning the potential to create a corridor of outstanding natural beauty stretching from the Simon Sand area through to Les Mielles.

"That's something we can certainly take a look at," he confirmed.

### Multiple Funding Avenues on the Table

Farnham acknowledged that a purchase of this scale would require creative financial planning, but noted several avenues worth exploring.

"There's public money if we decide to use it," he said. "There are other options with the National Trust, and I've had a number of people from our 21E community — wealthier residents — who are very keen to contribute to something like this."

The Chief Minister previously facilitated the acquisition of Cafe Romany at Grève de Lecq after similar public calls to protect the surrounding environment, demonstrating a precedent for this kind of intervention.

The National Trust of Jersey has so far declined to offer a public comment on the matter.

Jersey's Chief Minister supports bringing Les Mielles Golf Club into public ownership as campaigners push to restore the £9.95M site back to nature.

## NASA Celebrates America's 250th Anniversary With Four Spectacular Cosmic Images

To honor the United States' 250th birthday, NASA has unveiled four stunning deep-space images captured by its Chandra X-ray Observatory, each rendered in patriotic shades of red, white, and blue. The agency also introduced three new sonifications — transforming astronomical data into immersive soundscapes — giving the public yet another way to connect with the cosmos.

Each image combines Chandra's X-ray data with observations from other powerful telescopes, showcasing some of the universe's most extraordinary phenomena, from the remnants of a stellar explosion to a galaxy cluster holding clues about the mysterious nature of dark matter.

## Cassiopeia A: The Remnants of a Stellar Explosion

The first image spotlights Cassiopeia A, one of the most well-studied supernova remnants in the Milky Way. This composite brings together X-ray data from Chandra — displayed in blue and purple — with infrared imagery from NASA's James Webb Space Telescope, shown in red and white.

Chandra's contribution highlights the powerful shockwave generated by the original stellar explosion and reveals scattered elements within the debris field, including iron, calcium, and oxygen. Webb's infrared perspective captures the outward-expanding shell of material and the surrounding clouds of cosmic dust.

## NGC 3603: A Stellar Nursery Bursting With Young Stars

The second image showcases NGC 3603, a vibrant nebula within the Milky Way that hosts a dense cluster of newly formed stars. Chandra's X-ray data — rendered in red and white — exposes diffuse emission near the nebula's core along with numerous distinct X-ray point sources scattered throughout.

Layered on top, observations from NASA's Hubble Space Telescope across optical, infrared, and ultraviolet wavelengths add rich detail: tightly packed stars at the center and sweeping clouds of dust and gas along the lower regions. The result is a vivid tableau dominated by the patriotic color scheme while vividly illustrating the process of star birth.

## NGC 4736: A Spiral Galaxy With an Active Star-Forming Core

Also known as Messier 94, the spiral galaxy NGC 4736 takes center stage in the third image. Chandra's multi-energy X-ray observations — shown in red, orange, and blue — are layered with ground-based visible light photography contributed by astrophotographers.

At the galaxy's center lies a prominent starburst ring, a circular region where new stars are forming at a remarkable rate. Researchers believe this intense activity is driven by gas being funneled inward through the galaxy's distinctive oval-shaped structure, continuously feeding the star formation process.

## ZwCl 0024+1652: A Galaxy Cluster That Unlocks Dark Matter Secrets

The final image in the collection features ZwCl 0024+1652, a distant galaxy cluster that has become a key landmark in dark matter research. Enhanced Hubble observations rendered in blue reveal spatial evidence for dark matter's presence, while a separate Hubble view captures the cluster's individual galaxies in yellow and white.

Chandra contributes a glowing red cloud representing superheated gas that permeates the entire cluster. Remarkably, this vast reservoir of hot gas contains significantly more mass than all of the cluster's galaxies combined — a finding that continues to challenge and deepen our understanding of the universe's hidden structure.

## A Cosmic Tribute to an American Milestone

Together, these four images serve as both a patriotic tribute and a reminder of NASA's ongoing mission to explore and understand the universe. By combining cutting-edge observatories like Chandra, Webb, and Hubble, the agency continues to push the boundaries of human knowledge — one spectacular image at a time.

NASA honors the US 250th anniversary with four stunning Chandra X-ray Observatory images showcasing supernovas, nebulae, galaxies, and dark matter.

## Super Typhoon Bavi Strikes US Pacific Islands

Super Typhoon Bavi has descended on Guam and the Northern Mariana Islands, unleashing ferocious winds reaching nearly 290km/h (180mph) and gusts soaring as high as 350km/h. The storm is currently battering the region with relentless rain and violent conditions, as the western eye of Bavi tracks across these vulnerable Pacific territories.

## Catastrophic Conditions Warned by Weather Authorities

The US National Weather Service (NWS) has described Bavi as an extremely dangerous system capable of causing catastrophic destruction. Forecasters have warned of ocean swells potentially reaching close to 11 meters (35 feet) in height, posing severe threats to coastal communities and infrastructure.

Authorities cautioned that wind speeds are not expected to drop below typhoon force until early Monday afternoon, with tropical storm-level conditions persisting well past midnight.

## Rota Takes a Direct Hit

Among the hardest-hit locations is Rota, the southernmost inhabited island of the Northern Mariana Islands, situated approximately 50 kilometers northeast of Guam. The NWS confirmed the island is bearing the full brunt of the storm's impact.

Local officials issued urgent advisories urging residents to brace for destructive winds, warning that outdoor conditions would become life-threatening as the storm intensified. Authorities stressed that conditions were expected to deteriorate rapidly.

## Evacuation Efforts Underway Across Guam

Guam, a sun-drenched tourist destination that is home to roughly 170,000 residents, activated five emergency evacuation centers housed within school facilities. These centers carry a combined maximum capacity of approximately 1,700 people and are primarily designated for the island's most vulnerable populations.

By early Sunday afternoon local time, civil defense officials confirmed that one of the shelters had already reached full capacity, with displaced residents being redirected to alternative sites.

### Residents and Visitors Express Fear and Concern

Local business owner Pinky Cubacub, 55, described the difficult reality facing small business operators in Guam. Having spent around $500 (£373) on plywood to board up her restaurant, she expressed anxiety over the financial toll of prolonged closures.

"I cannot afford to lose so many days. It hurts," she told AFP. "Because I just started, whatever we're making right now is just for rent, utilities, and my people, and supplies. I don't even pay myself yet."

Japanese tourist Miku Sakurai, 25, found herself stranded after her Sunday return flight to Tokyo was cancelled due to the approaching storm. "We will stay in the hotel when the storm comes. I am scared," she said.

## What Classifies Bavi as a Super Typhoon

Bavi has been officially categorized as a super typhoon by the Joint Typhoon Warning Center (JTWC), the US military body responsible for monitoring tropical storm activity across the western Pacific. A storm earns this classification when sustained winds exceed 240km/h. The NWS equates super typhoons to category four or five hurricanes in terms of destructive potential.

## A Pattern of Increasing Intensity

Bavi marks the 11th category four or five tropical cyclone to strike US territory within the past decade — a figure that already surpasses the entire total recorded over the previous 57 years combined.

Scientists attribute this alarming trend to the accelerating effects of climate change. Rising sea surface temperatures inject greater volumes of moisture into the atmosphere, effectively supercharging storm systems. A powerful El Niño event currently underway is also expected to drive more tropical storms to extreme intensities across the region.

The western Pacific is already no stranger to severe typhoon activity this year. Super Typhoon Sinlaku struck Guam and the Northern Mariana Islands in April, claiming 17 lives and inflicting an estimated $1.5 billion (£1.1 billion) in damage.

## Climate Change Fueling More Powerful Storms

Experts warn that while intense typhoons have historically been unusual for US Pacific island territories, the frequency and severity of such storms is increasing as global temperatures rise. Warmer ocean waters continue to serve as fuel for increasingly powerful tropical cyclones, making communities across the Pacific more vulnerable than ever before.
